The Best SEO API Providers

Article credentials | Author: Robert Goldenowl; Publication date: October 20, 2025

Managing SEO data and insights manually has become time-consuming and prone to errors. Modern SEO professionals – especially agencies and developers – increasingly rely on APIs to automate data collection, integrate tools, and generate real-time insights. In an era where Google emphasizes E-E-A-T in content, using trusted data sources and expert-driven tools is more critical than ever for credible SEO strategies. This article will explain how to choose the best SEO API provider, key criteria to evaluate, why SEO APIs are vital for agencies, and how to get started. We’ll also compare the top 10 SEO API providers – with DataForSEO and SE Ranking leading the list – alongside other major players like Semrush and Ahrefs.

The Best SEO API Providers

How to Choose the Best SEO API Provider

Choosing an SEO API provider starts with understanding your specific needs and constraints. There is no one-size-fits-all API – the optimal choice is the one that solves your particular problems without breaking your budget or workflow. Begin by defining what you need the API for: is it rank tracking, keyword research, backlink analysis, technical audits, or all of the above? Different providers excel in different areas. For example, an enterprise team focused on backlink analytics might favor Ahrefs for its unparalleled link index, whereas a startup building a custom SEO dashboard might opt for DataForSEO’s broad data and pay-as-you-go flexibility.

Next, assess the scope and scale of data you require. If you manage thousands of keywords across many clients, look for providers known for high scalability and generous rate limits. If your focus is local SEO, prioritize APIs with strong geo-specific capabilities (e.g. location-based SERP results). It’s often wise to mix and match APIs as you grow: many successful SEO teams use 2–3 APIs in combination, since no single provider covers everything perfectly. As SEO strategist Ridam Khare notes, a smart approach is to start with one primary API that covers ~80% of your needs and supplement with specialized APIs for specific tasks. For instance, you might begin with a free Google Search Console API for your own site data, plus a comprehensive data API like DataForSEO (for competitor SERPs) or an affordable one like SE Ranking for general metrics. You can then add a backlink-specific API (Ahrefs or Moz) or a content-focused API (as needed) once you identify those gaps.

Finally, consider your team’s expertise and resources. Implementing an API requires some technical skill – at minimum, the ability to handle HTTP requests and parse JSON or CSV data. While some providers offer no-code solutions or pre-built connectors, truly leveraging an SEO API means coding and integration. As one expert puts it, “Let’s be honest – yes, you need at least basic programming skills or someone who has them” to use APIs effectively. If your team lacks development experience, look for providers with robust documentation, client libraries (SDKs), and even example code or support to help non-developers get started. Ease of integration can be a deciding factor in choosing the “best” API for you – because an expensive, powerful API means nothing if you can’t implement it properly in your workflow.

Key Criteria for Choosing an SEO API Provider

When evaluating SEO API providers, keep the following criteria in mind:
● Data Coverage & Accuracy: Ensure the API provides the types of data you need (SERP results, keywords, backlinks, technical metrics, etc.) with a reputation for accuracy. The breadth and depth of the data should match your use case. For example, DataForSEO boasts 100+ endpoints spanning rankings, keywords, backlinks, and more. Ahrefs offers an index of over 35 trillion backlinks updated every 15 minutes for top-tier link intelligence. Look for claims (and user feedback) on accuracy – e.g. DataForSEO’s rank tracking is noted for being within 0.1 position of manual checks. An expert from Longtail UX attests that DataForSEO delivers "100% accurate data" even at massive scale across regions, which speaks to its trustworthiness.
● Scalability and Rate Limits: Scalability is crucial if you plan to pull large volumes of data or run frequent queries. Check the provider’s rate limits and whether they apply per endpoint or overall. Some APIs allow high throughput (e.g. 100+ requests/second on enterprise plans), while others have strict limits (e.g. “10 calls per second” as with SE Ranking’s default). If you need to track tens of thousands of keywords or run heavy data pulls, opt for APIs known for high concurrency or asynchronous job processing. Also review their error-handling and throttling policies. As one guide notes, robust providers publish their SLA (Service Level Agreements), provide logs, and offer clear retry mechanisms – all ensuring you can reliably collect data at scale. The last thing you want is an automation breaking because you hit a hidden cap or got IP-blocked with no guidance.
● Pricing Model and Cost: SEO APIs vary widely in pricing structures – from pay-as-you-go credits to monthly subscriptions or tiered plans. Determine which model suits your budget and usage pattern. Pay-as-you-go (usage-based) models like DataForSEO can be cost-efficient if you only need certain data occasionally, as you “pay for what you use”. Subscription models (like Semrush or Ahrefs) often require a hefty monthly fee (e.g. Ahrefs API ~$500+/mo, Semrush ~$500/mo) but may include generous data allotments. Some providers have minimum spends or deposits (DataForSEO requires a ~$50 starting deposit, SE Ranking’s standalone API starts at $149/mo for 1M credits). Calculate your expected data needs (keywords to track, reports to run, etc.) and compare costs. Also watch for overage fees or upsells – e.g. Ahrefs charges extra per additional rows of data beyond plan limits. Transparent pricing and the ability to scale up or down without exorbitant costs is key. Don’t forget to factor in whether a free trial or freemium tier is available, which can help you test the waters. For instance, SE Ranking offers 100K free credits with a trial and DataForSEO provides trial access to all APIs.
● Integration & Documentation: A well-documented API with easy integration options can save hours of frustration. Look for comprehensive docs, code examples, and libraries for your preferred programming language. Some providers offer official SDKs or client libraries (e.g., wrappers in Python, JavaScript, etc.), and others rely on REST endpoints but may have community-contributed libraries. Consistency in how endpoints work (auth, pagination, etc.) also matters for smoother integration. Check if the provider has support for bulk operations or webhooks for large jobs. For example, providers like SerpAPI and Bright Data handle proxies and CAPTCHA-solving for you, simplifying SERP scraping integration. Support channels are part of integration ease too – if you run into issues, is there a responsive support team or community forum? Many top providers offer dedicated support for API users, and some even have account managers for enterprise clients. As a positive indicator, SE Ranking’s users praise its customer support and flexibility, noting the API allows extracting only the data needed without clutter.
● Reliability and Uptime: When you’re building critical reporting or automation on an API, it must be reliable. Investigate the provider’s uptime guarantees or status reports. Some providers, like Bright Data, pride themselves on infrastructure (claiming 99.99% uptime over two years for their SERP API). Read reviews or case studies: are there complaints of data outages or inconsistent results? Also consider how fresh and timely the data is – an API that provides real-time or daily-updated data is more valuable than one with stale data or long update intervals. For example, Google Search Console API is free but has a ~2-day data delay and only 16 months of historical data available, which could be a limitation for some analyses. Enterprise-grade APIs should handle high volumes without failing and provide consistent performance (some even let you choose standard vs. live priority modes depending on how real-time you need results).
● Features and Specialization: Look at any unique features that set the API apart. Does it offer something others don’t? For instance, some newer APIs incorporate AI-powered insights – e.g. Contently’s API (a 2024 entrant) can predict content “decay” (pages likely to drop in ranking). Others might excel in local SEO (detailed location targeting), or have unique metrics (Moz’s Domain Authority, Majestic’s Trust Flow). If a provider aligns with a niche need – like a JavaScript rendering for technical SEO audits, or share-of-voice metrics from full SERP captures – that could be the deciding factor. Create a checklist of must-have features (e.g. does it support Google’s new AI-generated results in SERPs?) and see which provider ticks the most boxes.
● Compliance and Ethics: As a professional consideration, use APIs that respect legal and ethical norms for data. Providers that gather publicly available data via scraping should have measures to comply with search engines’ terms and privacy laws. Some enterprise-focused APIs highlight their compliance, proxy management, and data security practices. Especially if you plan to resell data or integrate into client-facing tools, ensure the provider’s terms allow it and that they maintain high data integrity standards (this also ties into E-A-T, as trustworthy data underpins trustworthy content).
In short, choose an SEO API provider by balancing capabilities with credibility. A reliable API with slightly fewer features might be better than a feature-rich one that is unstable. Do your due diligence: read user reviews, ask for demos, and even negotiate enterprise contracts – as one expert wryly notes, “list prices are just the opening offer”. The right API partner will provide you with accurate data at scale, integrate smoothly into your systems, and support your team as you grow.

Why SEO API Providers Are Important for SEO Agencies

For SEO agencies, the ability to automate and scale is a game-changer. As an agency takes on more clients, tasks like keyword tracking, audits, reporting, and competitor analysis multiply quickly. APIs allow agencies to handle this workload without proportional headcount increases. Instead of manually pulling data from tools or running one-off reports, an API can feed data into dashboards and workflows continuously. This not only saves labor but also reduces human error, ensuring more reliable reporting for clients.
Efficiency and scalability are top benefits. According to Outscraper’s Ed Umbao, using APIs and automation helps agencies “streamline repetitive tasks and make scaling processes more efficient,” enabling one to take on multiple clients and deliver results “without the headaches of constant hiring.”. In practice, an API can unify various data sources – for example, pulling rankings from Google, backlinks from Ahrefs, and traffic stats from analytics – into one internal system. This unified workflow means teams spend less time logging into dozens of tools and more time analyzing insights. As a result, agencies can focus on strategy and optimization rather than data collection drudgery.
SEO APIs also empower agencies to offer advanced services and customization. With raw data access, agencies can build their own proprietary tools or dashboards that differentiate their services. For instance, an agency might use a rank tracking API to develop a custom client dashboard that updates daily, or use a content analysis API to create an automated content audit product. These value-adds would be impossible relying only on standard tool UI. “APIs create a unified workflow by connecting third-party tools easily,” effectively letting agencies craft bespoke solutions for clients. They also open opportunities for white-label reporting – pulling data via API and presenting it under the agency’s branding. Many providers explicitly allow and encourage this for agencies.
Crucially, APIs provide real-time responsiveness. Agencies can set up alerts or scripts via API to monitor sudden drops in rankings, spikes in crawl errors, or new competitor moves, and react immediately. One enterprise SEO director noted that after switching to the Ahrefs API, they caught negative SEO attacks “within hours instead of weeks,” which alone justified the cost. This kind of agility can significantly improve client satisfaction and outcomes.
Cost savings are another factor. While APIs are not cheap, they can be more cost-effective than using multiple tool subscriptions or hiring extra staff to do manual work. Automating data collection frees up team members to focus on analysis and strategy, which is a better use of expert talent. As one agency leader explains, using DataForSEO’s APIs “saves us time, money, and resources by eliminating the need to scrape everything in-house. This frees up our developers to work on core features that deliver value to our clients.”. In other words, let the API provider handle the heavy lifting of crawling/searching data, while your team uses that data to drive SEO results.
Additionally, integrating SEO data with other business data via APIs can elevate the role of SEO in an organization. Agencies that pull SEO metrics into client’s business intelligence tools can show SEO performance alongside sales or other KPIs, providing a more holistic view. This integration, made possible by APIs, often strengthens the agency’s strategic advisory role. A quote from an agency using SE Ranking’s API highlights this: “They [the API] enable a deeper integration of SEO and SEA insights… creating measurable synergies that directly impact our clients’ revenue.”. By blending search data with advertising or conversion data, agencies can demonstrate the full value of their work and make more data-driven decisions.
In summary, SEO APIs are vital for agencies to scale efficiently, maintain quality, and deliver advanced, data-driven services. They turn disparate data into a cohesive pipeline, enabling real-time monitoring, customized offerings, and resource savings. Agencies that leverage APIs effectively can outpace competitors by being more agile and insightful without ballooning their costs. In today’s fast-paced SEO landscape, that can be a decisive advantage.

How to Start Working with an SEO API Provider

Starting with an SEO API may seem technical, but by following a structured process you can integrate one step by step. Here’s a roadmap to begin working with your chosen SEO API provider:

Define Your Goals and Use Cases

Before diving into implementation, be clear on what you want to achieve with the API. Are you automating rank tracking reports? Building a custom SEO dashboard? Performing bulk keyword research? Defining the use case will guide which endpoints and data you need to focus on. For example, if your goal is to monitor daily rankings for 500 keywords, you’ll likely use a SERP or rank-tracking endpoint. If you want to enrich your content strategy, you might use endpoints for keyword suggestions or search volume. Knowing the end goal helps in planning the integration.

Choose the Right Provider and Plan

Using the criteria above, select the API provider that best fits your needs. If uncertain, take advantage of free trials or free tiers to test a couple of providers side by side. Many SEO APIs offer trial credits (e.g., SE Ranking provides a 14-day trial with 100K credits, and SerpAPI offers 250 free searches/month). During trials, evaluate data quality, speed, and ease of use. Also ensure the pricing plan you choose can scale if your usage grows – it’s often simplest to start with a lower plan or pay-as-you-go and upgrade as needed.

Obtain API Access (Keys or Tokens)

Once you’ve signed up, follow the provider’s instructions to get your API credentials. Typically, this involves logging into your account and generating an API key or OAuth token. For instance, with SE Ranking you’d go to Settings → API to create a key. Secure this credential as it will be used to authenticate your requests. Most APIs use a key in the request header or URL for authentication. Keep it private to prevent others from using your quota.

Read the Documentation and Examples

Before coding, spend time reading the API’s documentation. This is crucial for understanding endpoints, parameters, response formats, and any quirks. Look for quick-start guides or example code provided by the provider. Many offer sample requests in cURL or popular languages. Understanding the API’s data structure will save you headaches later – e.g., know how pagination works, or how rate limit headers are returned. If the provider has an API explorer or sandbox, try making a few test calls right in the documentation interface.

Make a Test API Call

Start with a simple test query to ensure you can successfully connect. For example, you might fetch your own website’s ranking for a single keyword or retrieve one page of SERP results. Use a tool like Postman or a basic script in Python/JavaScript to do this. Verify that you get a valid response and inspect the data format. This step confirms that your authentication works and that you understand the basics of forming requests. It’s often helpful to test the waters with a small call because some APIs have particular formats (like required URL encoding for queries, or specific request headers).

Implement in Your Application or Workflow

With a successful test, proceed to integrate the API into your workflow or application. This could mean writing a script that pulls data and stores it in a database, or connecting the API to a Google Sheet or BI tool. Focus on one functionality at a time – for instance, implement the rank fetching, then later the backlink data, rather than tackling everything at once. Ensure your code handles the API responses properly (parsing JSON, handling nulls, etc.). If you’re not a developer, some providers suggest using platforms like Google Colab with provided scripts, then output to Google Sheets – a semi-manual approach that can work for non-coders. However, for robust use, investing in development will pay off.

Handle Rate Limits and Errors

As you integrate, build in logic for rate limiting and error handling. APIs will return specific status codes if you exceed limits (e.g. HTTP 429 Too Many Requests). You should implement retries with exponential backoff (delay) when these occur. Also handle network errors or timeouts gracefully. Smart error handling ensures your automation runs smoothly even when there are hiccups. For example, if you plan to fetch 10,000 keywords’ data, you might need to queue requests or space them out according to the provider’s guidance. Nearly all providers document their rate limit policies – abide by them to avoid temporary bans.

Validate Data and Results

Don’t assume the data is correct or fits your need without validation. Cross-check a sample of API results against the provider’s web interface (if available) or against known values. For instance, verify that the “position 1” reported via API indeed matches a live Google search for that keyword (taking personalization into account). This will build trust that your integration works as expected. If you notice discrepancies, consult support or documentation – sometimes additional parameters (like specifying a location or device) might be needed to get the intended data.

Scale Up Gradually

After initial success with a small implementation, gradually expand your usage. Increase the number of keywords or sites you track, or integrate more endpoints once you’re comfortable. Remember the advice: “Start small. Test thoroughly. Scale gradually.” By ramping up slowly, you can monitor how performance and costs scale. This approach also helps in optimizing your code and avoiding overwhelming yourself with too much data at once. Monitor your API usage metrics if provided (many dashboards show how many requests or credits you’ve used) so you stay within quotas or know when to upgrade.

Leverage Support and Community

If you encounter challenges, reach out for help. Many API providers have dedicated support teams for their paying customers, and they can assist with troubleshooting or best practices. Some have communities (Slack groups, forums, or StackOverflow tags) where you can ask questions and share knowledge with other developers. Don’t hesitate to use these resources – for example, DataForSEO’s support is known to be “prompt and professional” in helping clients build data solutions. Getting guidance can accelerate your implementation and uncover features you might not have been using.

Integrate Monitoring and Updates

Finally, once your API usage is in production, set up monitoring. Track if the API responses change or if there are outages (some services allow subscribing to status alerts). Also, keep an eye on new features or deprecations announced by the provider. SEO is a fast-evolving field – new SERP features or changes (like Google’s SGE) may require updates to the API or new parameters. By staying updated (e.g., following the provider’s blog or release notes), you can take advantage of improvements.

Table: Comparison of top SEO API providers, highlighting their data focus, entry pricing, and primary strengths.
Below, we review each of these providers in detail:

DataForSEO API

1. DataForSEO

DataForSEO is often regarded as the “Swiss Army knife” of SEO data APIs. It offers an expansive range of data endpoints – including SERP results, keyword data (search volumes, suggestions, Google Trends), on-page and technical SEO data, backlinks, PPC data, and more – all delivered via a flexible pay-as-you-go API. This breadth makes DataForSEO a top choice for developers building custom SEO software or dashboards, as you can fetch almost any SEO metric you need from one provider. Users commonly praise its accuracy and value: the service is known for highly accurate SERP rankings (covering 230+ search engines in 195 countries in real time), and you only pay per request, which can be cost-efficient. According to Andreas Dzumla, co-founder of Longtail UX, “DataForSEO provide 100% accurate data, great value for money and a very flexible API for a great range of queries.” This sentiment is echoed by many agencies and SaaS companies that rely on DataForSEO as a backbone for their SEO data needs.
One standout aspect is DataForSEO’s granular control over cost and speed. They offer multiple query modes (Standard, Priority, Live) so you can decide to fetch data faster at higher cost or slower at lower cost. For instance, a standard SERP request might cost ~$0.0006, whereas real-time “live” mode is ~$0.002 per request. This transparency allows you to optimize spending. DataForSEO’s documentation is technical but thorough – indeed, it’s sometimes noted that their docs “read like they were written by engineers for engineers,” so expect a learning curve. However, the support team is reputed to be very helpful and responsive, which can assist during implementation. DataForSEO is constantly expanding their offerings (e.g., APIs for Google Trends-like data, search intent, etc.), making them a cutting-edge choice. Overall, DataForSEO is best for developers and agencies who want comprehensive SEO datasets with flexible, scalable usage. It’s the top pick if you plan to build your own tools and need raw data at scale, or if you require a one-stop-shop API to replace multiple tool-specific APIs.

SE Ranking API

2. SE Ranking

SE Ranking is a popular all-in-one SEO platform that also provides an API for direct data access. We place it at #2 for its balance of features and affordability – it’s often called the “workhorse” API that’s not the flashiest but gets the job done reliably. Through SE Ranking’s API, you can retrieve data on keyword rankings (including historical rank tracking), website audit results (technical SEO issues), backlink profiles, keyword suggestions, and more. Essentially, anything you can do on the SE Ranking platform, you can automate via the API. Agencies love this because you can integrate ranking reports, on-page check results, etc. into your own reporting systems or CRM.
One of SE Ranking API’s biggest strengths is cost-effective pricing. Unlike some competitors that require very expensive plans for API use, SE Ranking’s API starts at $149 per month (for ~1 million credits), which is accessible even to smaller agencies. Each data type (keyword, backlink, etc.) costs a certain number of credits – for example, a ranking for one keyword might be a fraction of a credit – making the model understandable and scalable. For higher needs, they have larger plans (their own site notes an advanced API plan around $239/month for higher limits). Users have highlighted that SE Ranking offers flexible usage without excess clutter: “It has cost-effective pricing with flexible usage models and allows us to extract only the data we need without excess clutter,” says Adam Heitzman of HigherVisibility. This aligns with agencies that want efficiency.
Technically, the SE Ranking API imposes a reasonable rate limit (to ensure stability) – currently about 10 requests per second to keep things smooth. It’s sufficient for most use cases, though heavy-duty users might supplement it with another API for bulk tasks. The data accuracy is generally good for rank tracking (though some independent reviews have noted minor discrepancies in certain cases). SE Ranking continuously updates its databases (daily refreshes for rankings, etc.), and also integrates new features like SERP feature tracking and even Google’s SERP AI results tracking as those emerge.
SE Ranking’s API is a great fit for SEO agencies and teams who already use SE Ranking or those who want an affordable entry into API usage. It’s particularly useful if you need a broad range of data (rankings, on-page, backlinks) in one package. The ease of use is notable – many find the learning curve gentle, and SE Ranking provides solid documentation plus a support team that can help enable API access (sometimes you need to request API activation if you’re an existing customer). In short, SE Ranking is a reliable, budget-friendly API that covers all major SEO bases. It may not have the ultra-granular SERP capabilities of DataForSEO or the sheer link index of Ahrefs, but for many agencies it hits the sweet spot of functionality and price.

Semrush API

3. Semrush

Semrush is a giant in the SEO tool space, and its API gives developers access to the wealth of data behind the Semrush platform. The Semrush API includes various modules: Analytics API (for domain stats, keyword research data, backlink info), Projects API (for data from your projects like position tracking, site audit results), and others covering things like traffic analytics. Essentially, it’s as if you took Semrush’s extensive UI and made it programmatically accessible. This means you can fetch keyword metrics (volumes, difficulties, CPC, competitive density), lists of keywords a domain ranks for, backlinks to a domain, and more. One area Semrush’s API shines is competitive research – for example, you can pull all the keywords two competing sites share or where one outranks the other, etc., which is great for creating competitive gap analyses automatically.
Semrush’s data is known for being broad: their keyword database and SERP analytics cover a huge number of queries and domains globally. They also offer data beyond pure SEO, like PPC (Google Ads) research data, which some other SEO APIs lack. If your focus is holistic digital marketing data, Semrush API is attractive. One feature users highlight is the Traffic Analytics API, which provides estimated traffic and visitor metrics for websites (approximate but useful for competitive benchmarking). This kind of data – approximating website traffic and user metrics – is something you can integrate to get a fuller picture of competitors.
However, Semrush’s API comes with a couple of considerations. First is cost: you generally need a Semrush Business account (~$499.95/month) and then purchase API units additionally. These API units are like credits that different calls consume. So, using the API substantially can become quite expensive, especially for smaller operations. Second, not all parts of Semrush’s data are equally strong. As one analysis noted, “their traffic analytics [via API] provides estimates surprisingly close to reality... but their backlink API? Honestly, don’t bother with it unless you have no other options.”. Indeed, Semrush’s backlink database, while large, is often considered less comprehensive than Ahrefs or Moz for hardcore link analysis. Thus, many teams use Semrush API for keywords and competitive intel, but might rely on another for backlinks.
Semrush provides solid documentation through their developer portal, and given their user base, there’s a community of developers familiar with it. The API is best for companies already invested in Semrush – for example, agencies who use Semrush extensively and want to automate reporting from it. It’s also a top choice if you need multi-faceted SEO+PPC data. Semrush’s API can empower custom tools for keyword research at scale, content planning (with keyword and topic metrics), and competitive benchmarking. Just be mindful of the cost and consider mixing data sources (as Semrush themselves suggests: use their API for what it excels at, and “look elsewhere” for things like detailed link data).

Ahrefs API

4. Ahrefs

Ahrefs offers one of the most powerful – and premium – SEO data APIs, renowned especially for its link index. Ahrefs API provides programmatic access to its core datasets: backlinks and referring domains, organic search rankings for websites, keyword search volumes and difficulty (via their Keywords Explorer data), and even their content explorer data (popular content by social shares/links). If backlinks are a significant part of your strategy or service (like link audits, competitive link analysis, digital PR tracking), Ahrefs API is often considered the gold standard. Their continually updated link index and proprietary metrics like UR/DR (URL Rating and Domain Rating) allow for very in-depth link analysis via API.
Ahrefs is frequently described as the "Lamborghini" of SEO APIs – very powerful, but at a high price. To access it, you not only need a high-tier Ahrefs subscription, but also pay a minimum of ~$500/month for API access. Large enterprises may pay thousands per month for bulk data. For that investment, you get unparalleled data freshness and scale in certain areas. A real-world benefit: one enterprise SEO director mentioned that by hooking into Ahrefs’ API, their team detected negative SEO (spammy backlinks attacking their site) within hours, instead of it going unnoticed for weeks. This underscores how real-time link monitoring via Ahrefs can provide immediate ROI for those who need it.
The Ahrefs API has endpoints to query things like: get all backlinks for a domain (with filters), get new/lost backlinks, retrieve keywords a site ranks for, retrieve top pages by links, and more. The link data is arguably the richest – with context like anchor text, follow/nofollow, etc., and very large export limits (if you have the units purchased). It’s fantastic for competitive research too (e.g., find which sites link to your competitors but not to you). For keyword data, Ahrefs is decent, though some prefer Semrush or others for keyword breadth. Where Ahrefs might be slightly weaker is data outside the SEO realm (they don’t focus on things like website traffic estimations or technical crawling in their API – it’s mostly backlinks and rankings).
Implementing Ahrefs API requires careful consideration of units consumption because heavy data pulls (like all backlinks of a high-authority site) can eat through credits fast. The API returns data in pages (e.g., 1000 rows at a time), and large jobs can be time-consuming. Some users note that “sometimes the data feels a little behind, especially when tracking backlinks or keyword rankings”, meaning that even with frequent updates, there might be slight delays in reflecting the absolute latest. Still, it’s more up-to-date than most other tools in link tracking.
In summary, Ahrefs API is best for those who need top-tier backlink data and are willing to invest for quality. Agencies doing a lot of link audits, or software companies offering backlink analysis features, find Ahrefs invaluable. It’s also very useful to supplement another API: for example, you might use DataForSEO for SERPs and Ahrefs for backlinks to get the best of both worlds. If budget is a concern, Ahrefs API might be overkill; but if link intelligence is mission-critical, it’s hard to beat.

Moz’s API

5. Moz (Mozscape API)

Moz provides an API (often called Mozscape) that gives access to its SEO data, most famously the Domain Authority (DA) and Page Authority (PA) metrics. Moz’s link index was one of the earliest in the industry, and while smaller than Ahrefs’ index today, it’s still substantial (Moz claims tens of trillions of links indexed). The Moz API allows queries like retrieving the DA, PA, number of linking domains, and spam score for a given URL or domain; pulling top pages or links for a domain; and running some limited keyword data (Moz has a keyword database too, though not as extensive as others). It’s a bit more limited in scope – largely focusing on link metrics and site authority signals.
One appealing factor of Moz’s API is its simplicity and cost flexibility. They often operate on a unit-based system with relatively low entry cost. For example, you might pay just a few dollars for thousands of URL metrics queries (the snippet from Coefficient shows “From $5” which likely indicates you can buy small blocks of usage for cheap). This makes Moz’s data accessible to those on a budget or who only need occasional data. Some third-party SEO dashboards and reporting tools use Moz’s API specifically to fetch DA/PA scores, since Domain Authority has become a client-friendly number to show (many clients understand it as an authority benchmark).
In terms of strengths, Moz’s authority and spam metrics are unique. Domain Authority (scaled 0-100) is widely cited in the SEO industry. Moz’s Spam Score can flag potentially harmful link profiles. These are valuable for quick site evaluations or link prospecting via API. Moz also offers historical index data, which can be useful if you want to see how a site’s link profile has grown over time. The API endpoints allow filtering and selecting specific data fields to keep responses lean.
However, Moz’s coverage of other areas is not as comprehensive. For serious rank tracking or keyword research, their API is not the top choice (Moz Pro’s keyword data is decent but not as large as Semrush/Ahrefs, and their rank tracking API is mostly for one’s own projects). Also, the update frequency of Moz’s link index historically was slower than Ahrefs/Majestic (though they’ve improved it with rolling updates).
Moz’s API is ideal for lightweight link data needs and augmenting other data. For example, a developer might pull data from another source but call Moz API to get the DA/PA for each URL for an extra layer of insight. It’s also suitable for those who want affordable access to link metrics without needing a huge index – small businesses or consultants might use Moz to quickly gauge sites. The API documentation is straightforward and Moz has a developer community given their long-standing presence.
All in all, Moz might not be the singular solution for all SEO data, but it’s a reputable, trusted source for key link metrics. Its inclusion in the top 10 is warranted by the ubiquity of Domain Authority in SEO discussions and the convenience of grabbing those metrics via API for your reports or tools.

Majestic’s API

6. Majestic

Majestic (also known historically as Majestic SEO) is another veteran in the SEO data space focused on backlinks. Majestic’s API gives you access to their extensive link database and proprietary metrics like Trust Flow and Citation Flow. Trust Flow aims to measure link quality based on a seed set of trusted sites, while Citation Flow measures the sheer quantity of links. The combination of these metrics is often used to evaluate backlink profiles (e.g., a site with high Citation Flow but low Trust Flow might have a lot of links but of suspect quality). Many SEO professionals still use these metrics alongside Moz’s DA or Ahrefs’ DR for a comprehensive view.
Majestic’s link index is comparable in scale to Moz/Ahrefs – on the order of billions of URLs crawled and updated frequently. The API allows you to query for all the backlinks to a domain or URL, get a list of referring domains, check the index volume (how many URLs/pages Majestic has seen for a site), and pull those Flow metrics. Majestic also has a historical index mode vs. fresh index mode – you can query data from the past (useful for seeing old lost links etc.) if needed.
The API pricing for Majestic is geared towards heavier users: as noted, the API plan starts around $399.99/month, which provides a large allotment of query units (e.g., 100 million analysis units). They also have larger plans for more units (and smaller read-only API options via their Silver/Gold plans but with limited capabilities). This means Majestic is primarily used by agencies or tools that need bulk link data regularly, rather than individuals doing occasional checks (those might use the web interface or smaller exports).
One area Majestic might shine is in bulk backlink analysis – they have commands to submit a batch of URLs and get link counts or metrics for each, which can be very useful for auditing lists of pages or doing competitive domain profiling at scale. Also, Majestic explicitly encourages developers and even allows certain data to be resold (with terms), which is why many SEO software (like various link analysis tools or SEO auditors) incorporate Majestic’s API under the hood.
Majestic’s data has historically been prized for its Trust Flow metric, which some consider a more reliable spam/quality indicator than others. For example, link auditors might use Majestic API to quickly find toxic links (very low Trust Flow or out-of-context links). However, Majestic’s interface and ecosystem feel a bit more old-school, and some modern SEOs have gravitated more to Ahrefs or Semrush unless they specifically need Majestic. Still, many agencies keep a Majestic subscription for that alternative view of backlinks.
In our list, Majestic is best for specialists in link building and auditing, or developers needing another lens on link data. It’s a strong supplemental API if you’re dealing with a lot of backlink analytics. While it doesn’t cover keywords or on-page data (Majestic is almost entirely about links), it covers that niche deeply. If your workflow values Trust Flow/Citation Flow or you need double-checks against another link source, Majestic is the go-to. Just budget accordingly and be prepared to handle potentially very large data outputs if pulling all links for big sites.

Serpstat’s API

7. Serpstat

Serpstat is an all-in-one SEO platform that emerged from Eastern Europe and has grown globally as a cost-effective alternative to the likes of Semrush. Serpstat’s API provides access to a range of SEO data: keyword research (including international databases, keyword difficulty, trends), organic and paid competitor analysis, backlink data, rank tracking, and site audit results. It aims to cover the spectrum of SEO needs, making it a one-stop solution similar in concept to Semrush or SE Ranking, but often at a different price point.
One reason to consider Serpstat API is its competitive pricing for volume. As indicated, their API access can start around $1,000 per year for a base tier, which, on a monthly basis, is quite affordable compared to big players. They use a credit system too, and Serpstat tends to give generous credit allotments. This means for agencies or developers on a tighter budget, Serpstat might allow a lot of data pulls without breaking the bank. They also have had promotions and custom enterprise deals that can be attractive.
Feature-wise, Serpstat might not have the absolute largest database in each category, but it’s robust. It has particularly strong data for certain regions (it originated in Ukraine/Russia market, so its databases for Eastern European search engines/languages are rich). It covers Google worldwide too, with indices of keywords for many countries. The API can let you do things like get the top keywords for a domain, find keyword suggestions, get rank tracking results for your projects, and retrieve backlinks with Serpstat’s own metrics (they have a Visibility score, etc.). In their own content, they highlight how API helps to combine data sources and create custom solutions, echoing the general benefits of APIs.
Serpstat’s API and documentation are fairly straightforward. They also invest in content that guides users (e.g., they have a public API documentation and even blog posts on using their API in Python or R for automation). This makes it approachable for data analysts who might not be hardcore developers but want to try some scripts.
In practice, Serpstat is best for marketing agencies or developers who want a well-rounded SEO data source at a reasonable cost. It can be thought of as a “value” choice: you get multiple types of data, maybe not the absolute top in each category, but good enough for many purposes. For example, if you need to pull keyword rankings and also get keyword suggestions and some backlink info and you can’t afford separate Ahrefs + Semrush + others, Serpstat can cover a bit of everything. Some users pair Serpstat with one specialized tool (like maybe Serpstat + Ahrefs, since Serpstat’s backlinks might not be as rich, that combo still costs less than Semrush + Ahrefs).
Serpstat’s platform is continually improving its data (they often expand their keyword DBs and features yearly). The API is an extension of that platform. So, if you are an SEO professional or developer looking for a budget-friendly yet capable API, Serpstat deserves a close look. It reflects the idea that “you can access vast datasets using an API” affordably, which has long been a challenge for SEO pros – Serpstat aims to solve that with its pricing strategy.

SerpAPI

8. SerpAPI

Despite a similar name, SerpAPI is a distinct provider (serpapi.com) with a laser focus: Google and other search engine results scraping via API. It’s included in this list for its developer-friendly approach to getting live SERPs without the hassle of managing proxies or parsers. SerpAPI essentially provides a real-time on-demand SERP extraction service. You send an API request specifying a query and perhaps location, device, etc., and it returns the structured results of the search engine page (in JSON, including organic listings, ads, snippets, etc.). It covers Google primarily, but also Bing, Yahoo, Yandex, Baidu, YouTube, Amazon, and some others – making it quite comprehensive for multi-engine needs.
What sets SerpAPI apart is that it solves many practical headaches for you. It has built-in proxy rotation and CAPTCHA handling, meaning you don’t have to worry about Google blocking your IP for automated queries; SerpAPI handles that on their end. They even can render JavaScript and get things like Google’s localized or “People Also Ask” sections properly. Essentially, it abstracts the whole process of SERP scraping into a simple API call. This is incredibly useful for developers who need live search data (like position tracking on the fly, competitive analysis, monitoring of specific snippets) without building their own scraper infrastructure.
SerpAPI’s pricing is subscription-based with a free tier. The free tier (at time of writing) is 250 searches per month which is great for testing or small projects. Paid plans start at $75/month for 5,000 searches, and scale up with higher volume plans. It’s not the cheapest per search compared to doing it yourself, but for the convenience and reliability, many find it worth it. Also, you only pay for successful requests; their system doesn’t count failures against you, which is nice.
One of SerpAPI’s notable features is speed – they claim extremely fast response times since they parallelize the scraping on their side. They also keep up with SERP changes very quickly; for example, when Google started rolling out its AI-generated answers (SGE), SerpAPI introduced ways to retrieve those. Similarly, they have support for things like news, images, maps, shopping results through specialized endpoints. This means if you need something like Google Maps API data (not just SEO but local search data), SerpAPI might do it.
Developers often praise SerpAPI’s ease of integration – they provide client libraries in multiple languages and have an active support team. On G2, a review mentioned “integration has been easy, and SerpAPI's support has been fast and helpful.”. That speaks to the developer experience which is a big plus in an API service.
In our context, SerpAPI is best for real-time rank tracking and SERP analysis needs, especially when multiple engines or no-code scraping is required. SEO software companies use it to power their rank checking features, and some agencies might use it to grab on-demand SERPs for reporting or research (e.g., pulling the current top 10 results for 100 keywords to analyze competition). It doesn’t give you historical databases or keyword suggestions (that’s not its aim), so it often pairs with a data API like DataForSEO or Semrush for those aspects. But for what it does, SerpAPI is highly specialized and excellent. It exemplifies the idea of “SERP APIs as a specialized tool” distinct from broader SEO APIs – you might need both types depending on your project.

Bright Data’s SERP API

9. Bright Data (SERP API)

Bright Data, formerly known as Luminati, is a well-known data collection (web scraping) platform. They offer a specific SERP API for search engine results, targeted at those who need to scrape search results at very high volumes or with extensive customization. Bright Data leverages its huge proxy network and infrastructure to deliver search results from Google, Bing, Yahoo, DuckDuckGo, etc., similar in goal to SerpAPI but geared more towards large enterprises. It’s a bit like the “AWS of web data”: extremely powerful and configurable, but also complex in pricing and options.
Bright Data’s SERP API can handle nearly unlimited concurrency – they advertise unmetered or very high throughput and pride themselves on reliability. As mentioned, they reportedly have 99.99% uptime and laugh at things like CAPTCHAs because of their advanced proxy/emulation setup. They can retrieve raw HTML or structured JSON results, handle headless browser rendering for heavy pages, and allow geotargeting down to city level or specific devices. This is valuable if you need to mimic a real user in, say, Paris on an iPhone, searching Google.fr – Bright Data can do that at scale.
The pricing model is complex. Bright Data often charges on a pay-per-use basis factoring in the number of results, bandwidth, and other parameters. The snippet indicates an example like ~$0.75 per 1000 results for their base rate, but in practice one has to also maintain a minimum deposit and possibly pay for additional proxy bandwidth. They have volume-based plans (Growth, Business, Premium tiers) with better rates for large commitments. Essentially, Bright Data can get expensive, but it can also be cost-efficient at massive scale where other APIs might not even offer the capacity.
One advantage of Bright Data’s API is integration into larger data workflows. Companies that have data engineering teams might plug Bright Data into pipelines that feed directly into databases or machine learning models (indeed Bright Data is used beyond SEO, for scraping prices, ecommerce data, etc.). They provide tools like webhooks for asynchronous job completion – you can fire off a million queries and get callbacks when data is ready, which is important at scale. They even offer a GUI and integrations for non-devs, but for the API, expect to have developer resources to manage it.
Bright Data is best for enterprise-level needs or highly technical SEO teams. For example, a large SEO agency or a search intelligence startup that needs to pull millions of SERPs per day across the world might use Bright Data because it can handle that volume reliably. It’s likely overkill for smaller operations – services like SerpAPI or DataForSEO are simpler if your volume is moderate. However, Bright Data often competes with DataForSEO’s SERP API on the high end; each has its loyal users. There’s also a direct comparison by some users noting Bright Data offers real-time flexibility while DataForSEO is very cost-effective with structured outputs.
In sum, Bright Data’s SERP API earns a spot in top 10 as the go-to for heavy-duty SERP data extraction. It’s like the enterprise solution where you “pay for what you need – proxies, bandwidth, geography – in a very granular way”. The learning curve on pricing and configuration is non-trivial (imagine AWS vs a simple hosting service), but once mastered, it delivers incredible power. If you have large-scale needs and the technical chops, Bright Data can be a game-changing provider.

SpyFu’s API

10. SpyFu

SpyFu is a long-standing SEO and PPC research tool known for its strong focus on competitor keyword analysis. SpyFu’s API is less publicized than some others on this list, but it exists and allows users (with certain plans) to pull data like: top organic keywords for a domain, top paid keywords for a domain, SEO and PPC competitors for a domain, and keyword stats (volume, CPC, click-through rates, etc.). Essentially, anything you see in SpyFu’s interface for competitive research can be automated via their API. This is especially useful for agencies that prepare competitor profiles or want to integrate competitive insights into their reporting dashboards.
SpyFu has made a name by historically offering unlimited search results and data exports on their platform at a fixed price, which is unique. Their pricing for API access comes with their Team plan (around $299/month), which is quite affordable relative to the volume of data you can get. With that plan, you can make a generous number of API calls (they mention tens of thousands of rows of data). This flat pricing model can be appealing if you need to run regular bulk reports without worrying about per-unit costs.
One of SpyFu API’s strengths is simplicity in competitive data. For example, you can query a domain and get all the keywords it ranks for in Google’s top 50, along with each keyword’s search volume and that domain’s ranking position. You could also get all the Google Ads keywords a domain has bought. This is valuable for creating competitor audit documents or for feeding data into a content strategy (knowing what keywords competitors target). SpyFu’s data isn’t as large-scale as Semrush’s, but it’s often sufficient and sometimes even better in terms of historical coverage for certain keywords (they track many years of data).
A noteworthy feature SpyFu provides (though not sure if via API or just UI) is historical ranking and ad performance – they have SERP snapshots going back over a decade for many keywords. This can allow trend analysis. If accessible via API, one could pull how a domain’s ranking on a keyword changed over time.
However, SpyFu’s limitations include that it primarily covers Google US (and a few other countries) data – it’s not as international as others. Also, it doesn’t have a site audit or crawler component; it’s purely about search marketing data. So, as an API, think of it as a specialized competitive keyword intel source.
SpyFu is best suited for agencies and marketers interested in competitor research and keyword-focused analysis without a huge budget. For instance, a small agency could use SpyFu’s API to generate monthly competitor ranking reports for clients, showing how they stack up. It’s also potentially useful for PPC campaign planning, given the API can reveal competitors’ ad history.
In the context of E-E-A-T and trust, SpyFu’s data can add an extra layer of insight (experience) about the competitive landscape that more authoritative strategies can be built on. By knowing what worked for others, SEO professionals can craft informed campaigns.
While not as all-encompassing as some others above, SpyFu earns a place in the top 10 for its unique value proposition: affordable, rich competitor data at your fingertips. It often flies under the radar, but many experts quietly use SpyFu alongside bigger tools to double-check and uncover opportunities that others might miss.
