10 Best Rank Tracking APIs for Accurate Keyword Tracking

A rank tracking API returns Google results for a keyword, location, and device as structured data, so a script can find your domain’s position and store it every day without anyone opening a browser. The ten services below do this in one of two ways. Four of them sell raw SERP data by the request (HasData, DataForSEO, Bright Data, and GeoRanker’s API plans), and six are rank tracking platforms with a dashboard that also offer an API, on some or all of their plans or as a separate product (Semrush, Accuranker, Authority Labs, SE Ranking, SheerSEO, Nightwatch).

What is Rank Tracking in Search Engines

Rank tracking means checking, on a schedule, which position a page holds in search results for a given keyword, location, and device. A rank tracker API does the SERP fetch for you. Vendors sell the same call under several names (rank tracker API, keyword ranking API, SEO ranking API, rank checker API). You send the keyword and location, the service loads the results page through its own proxies, parses it, and returns JSON with every organic result, its position, title, and URL. Your side of the job is to find your domain in that list, save the position with a timestamp, and compare it with yesterday’s.

The alternative is a rank tracking platform. It runs the same checks on its own schedule, stores history, and draws the charts, but you pay per tracked keyword and work inside its interface. Most platforms on this list also open an API, usually on higher plans, so the difference between the two groups is where the data ends up. With a raw SERP API you own the storage and the reporting. With a platform API you read what the platform has already collected. The same split applies to SEO APIs in general, where keyword and backlink data come either as a raw feed or as an export from a platform.

Criteria for Choosing Rank Tracking APIs

The comparison below rests on six criteria.

Functionality and Features

SEO work needs more than your own position for each keyword. You also need the full top 100 for the keyword, so you can see who ranks above you, the SERP features around the organic results (local pack, People Also Ask, AI Overview), and SERP history so a drop can be traced to a date. For an API that means reading what the response contains. For a platform it means checking which of these views exist in the dashboard and whether the API exposes them or only the position table.

Data Accuracy

Freshness is the first accuracy question. A platform that re-checks positions once a week cannot show you a drop that happened on Tuesday, and daily updates are the minimum for anything you act on. Raw SERP APIs fetch the page when you ask, so freshness is your scheduler’s problem rather than the vendor’s. Location fidelity is the second. Google personalizes by location, so a check from a data center in Virginia does not show what a user in Austin sees. Look for city or ZIP-level targeting and for a statement of how the vendor gets there, whether through local proxies or through Google’s uule location parameter.

User Interface and Ease of Use

Pure APIs rarely have an interface beyond an account page, so judge them by their documentation. Look for a request builder that produces working code in your language, a playground for testing a query, and a documented response schema. For platforms, check whether the API documentation is as complete as the product tour.

Integration and Ecosystem

If you build your own tracker, the integration question is which SDKs, webhooks, and callback options the API offers, and whether it can be called from tools like n8n, Make, or an MCP server. If you use a platform, ask which of your existing sources it pulls in, typically Google Search Console and Google Analytics, and where the reports can be exported.

Pricing and Availability

Platforms charge per tracked keyword per month, so 1,000 keywords cost the same whether you look at them daily or once. Raw SERP APIs charge per request or per credit, so the same 1,000 keywords checked daily cost 30,000 requests a month, and checked weekly cost about 4,300. Price the workload you plan to run rather than the entry plan. Also check whether the API is on the plan you can afford, because on several platforms it sits on the top tier only. A free trial or a permanent free tier lets you test location handling and parsing on your own keywords before paying.

Customer Support and Service

For an API, support means response times on failed requests and a status page. For a platform, it means someone who can explain why a position differs from what you see in your own browser. Dedicated or priority support appears only on the top tiers at HasData, Semrush, Accuranker, SE Ranking, Nightwatch, and Bright Data, GeoRanker advertises 24/7 live support, DataForSEO says nothing about support on its pricing page, and none of the ten states a response time. Ask before you commit.

The Best Rank Tracker APIs

The list is not ranked. The table is the comparison, the sections below give the reasoning.

Plan details are current as of the article’s last update.

Moz and Ahrefs also track positions, as part of suites that include backlink analysis, site audits, and competitive research. If position tracking is the only thing you need, you pay for the suite anyway, so they are left off this list.

HasData

HasData is a web scraping platform with a general Web Scraping API, site-specific scraper APIs, and no-code scrapers run from a dashboard. For rank tracking the relevant pieces are the Google SERP API, which returns the full results page as JSON, and the Google Rank Checker API, which returns the organic results at half the credits. Both take a keyword, a Google location, and a language, the full SERP API adds a device type, and both route the request through HasData’s own proxies for the location you specify. HasData is our own product. I wrote its con the same way I wrote the other nine.

Pros and Cons

The API returns every organic result with position, title, link, and displayed URL, plus the related searches, so one call covers your own position and the competitors above it. Location can be set as a Google canonical location string or an encoded uule value, down to city level. Proxy rotation, retries, and parsing of Google’s changing layout are handled on the API side, so your request is a single GET with the query and location.

The con is that HasData is not a full rank tracker, so there is no position history. A call returns the positions for today, and yesterday’s exist only if you stored them. Saving each day’s position per keyword in a database or in a spreadsheet closes that gap, and the request below is the whole input side of that job.

Request and response

One GET with the query and a Google location is the whole request. Each call costs five credits, and the key goes in the x-api-key header. This is the call for a keyword in Austin, Texas.

curl -G "https://api.hasdata.com/scrape/google-light/serp" \
  --data-urlencode "q=rank tracker api" \
  --data-urlencode "location=Austin,Texas,United States" \
  -H "x-api-key: $HASDATA_API_KEY"

Trimmed to the first two organic results, the response looked like this.

{
  "searchInformation": {
    "queryDisplayed": "rank tracker api",
    "appliedLocation": { "location": "Austin, Texas" }
  },
  "organicResults": [
    {
      "position": 1,
      "title": "Rank Tracking API - 5K requests/Month for Free - Bright Data",
      "link": "https://brightdata.com/products/serp-api/rank-tracking",
      "displayedLink": "brightdata.com › Products › SERP API"
    },
    {
      "position": 2,
      "title": "Rank Tracking App - DataForSEO",
      "link": "https://dataforseo.com/solutions/rank-tracking-app",
      "displayedLink": "dataforseo.com › Solutions"
    }
    // ... 7 more organic results
  ],
  "relatedSearches": [
    { "query": "Rank tracker api free" },
    { "query": "Rank tracker api github" }
  ]
}

Finding your own domain is a filter on link over organicResults, and position is the number to store. The SERP Light docs list the remaining parameters. A missing or wrong key returns 401 Unauthorized, more parallel requests than the plan allows return 429 Too Many Requests, and once the credit balance reaches zero new requests are refused until it is topped up. The documentation includes a request builder that generates the same call in cURL, Python, Node.js, PHP, Java, C#, or Ruby, and the API is also reachable through an MCP server, a CLI, and n8n and Make integrations.

Pricing

HasData gives 1,000 credits at sign-up with a 30-day trial of the paid features and no card required, and the free plan after that is topped up to 100 credits every day (a balance below 100 goes back to 100, credits do not accumulate). Paid plans are priced by monthly credits and concurrency, from Startup and Basic to Growth, which is sold in four credit volumes, and annual billing gives two months free. A Rank Checker call costs five credits and a full SERP call ten, so the price of one check falls as the plan grows. Current figures are on the pricing page.

Semrush

Semrush is an SEO and marketing platform. Rank tracking is one module, Position Tracking, and it is included from the entry plan.

Pros and Cons

The platform covers keyword research, competitor analysis, backlink analysis, site audits, and, on current plans, tracking of visibility in AI search as well as Google. The downside for a tracking-only use case is that you buy the whole suite, and the API sits on the top plan only.

Position Tracking

Position Tracking checks a set of keywords daily per project, with multi-location and multi-device tracking from the Pro+ plan upward. Keyword caps grow with the plan, from 500 tracked keywords a day on the entry plan to 5,000 on Advanced.

Pricing

Plans are monthly subscriptions with a discount for annual billing, and each tier fixes the number of keywords tracked daily. API access requires the top SEO plan (named Advanced on the current pricing page), and API units are bought separately on top of the subscription, so API-based rank tracking on Semrush costs the subscription plus per-unit fees. A free trial is available.

Accuranker

Accuranker is a rank tracking platform with daily updates, aimed at agencies and in-house teams. A read API is included from the Expert plan, and a write API from Enterprise.

Pros and Cons

Rank checks run daily, with local and mobile tracking, tagging, search intent, and integrations with Google Search Console and Google Analytics. Reporting can be customized and exported, and the Expert plan adds a Google Data Studio connector. The drawbacks are for small sites. The smallest plan starts at 2,000 keywords, there is no free trial, only a demo on request, and API access starts one tier up.

Read and write API

The read API has no call limit on the plans that include it and covers keyword rankings, domain metrics, and landing page data. Enterprise adds a write API, raw SERP HTML, and a BigQuery export.

Pricing

Plans are priced per tracked keyword with a discount for annual payment. Professional covers 2,000 to 5,000 keywords, Expert covers 10,000 to 25,000 and includes the read API, and Enterprise is quoted individually above 25,000 keywords.

Authority Labs

Authority Labs is a rank tracking service whose site now carries the ScraperAPI, LLC copyright, and whose standalone data API is sold under the separate Traject Data brand. The tracking product is still sold with interface API access on every plan.

Pros and Cons

Local and global rank tracking and competitor tracking are on every plan. The set of SEO analysis features around tracking is smaller than Semrush’s or SE Ranking’s, which is a plus if tracking is all you want to pay for.

Pricing

There are four monthly tiers, from 250 keywords and 50 domains on the smallest to 5,000 or more keywords with unlimited domains on Enterprise, each with a 14-day free trial and no card required, and accounts can move between tiers at any time. Every tier lists interface API access, and the API documentation is public.

GeoRanker

GeoRanker has two separate products. The platform tracks keywords with local results, and the High Volume API returns raw SERPs for building your own tracker, with credits sold separately from the platform plans.

Pros and Cons

GeoRanker sells location. Results are collected with local IPs, and both the platform and the API report rankings per city. The platform’s keyword caps are low, 100 tracked keywords on the entry plan against 250 at Authority Labs and 500 at Semrush and Nightwatch, so tracking thousands of keywords means the API side and your own storage and reporting.

Rank Tracker API

The Rank Tracker API returns results for any search engine, on desktop, mobile, or tablet, for any location, either parsed or as raw HTML. Requests can be delivered to a callback URL, and the service level sets the speed. Standard delivers within 24 hours, realtime within 5 minutes, instant within 30 seconds. The account limits are 15 simultaneous connections and 100,000 credits per hour.

Pricing

The platform has three monthly plans with a 7-day trial, capped by keywords tracked and monthly credits. The API is sold as prepaid credit packages. One Google SERP page costs one credit at the standard speed, two at realtime, and three at instant, and packages scale from a small top-up to custom volumes above 100 million credits.

SE Ranking

SE Ranking is an SEO platform for agencies and in-house teams. Rank tracking, keyword research, backlink research, and site audits are on every plan, and so is API access.

Pros and Cons

Every plan includes an API credit allowance and MCP access, so you can pull tracked positions into your own reporting without upgrading. Rank tracking covers the major search engines, with local and map rank tracking available. Historical data across the whole project lifetime and page change monitoring start on the Growth plan, and the full API with advanced integrations is Enterprise only.

Plans and integrations

Core tracks 2,000 keywords daily across 10 projects, Growth tracks 5,000 across 30 projects, and extra keywords can be added to either. Integrations include Google Search Console, Google Analytics, Matomo, and Looker Studio.

Pricing

Plans are monthly with a 20 percent discount for annual billing, and each fixes the number of tracked keywords and the API credit allowance. A 14-day trial needs no card. Separate API-only plans exist for the data APIs if you want the keyword and backlink databases without the platform.

SheerSEO

SheerSEO is an SEO tool aimed at small sites, with rank tracking for Google, Bing, and YouTube, and a separate SEO API with Rank and SERPs endpoints.

Pros and Cons

There is a free-forever plan with no card required. Paid plans are priced per domain, so the cost grows with the number of sites rather than the number of keywords. The API is a separate product with its own documentation and its own pricing.

Tracker and SEO API

The tracker reports local city and mobile rankings and shows search volume, clicks, and history per keyword. The SEO API covers Google and Bing positions, local results down to ZIP code, mobile and desktop, and more than 40 countries, and it is documented with a Swagger UI.

Pricing

The tracker has a free plan and per-domain paid plans. The API is sold either as pay-per-use credits or as monthly plans with better rates. SheerSEO’s own claim is that its API has the lowest price on the market. Check it against DataForSEO and Bright Data at your own volume before taking it at face value.

Nightwatch

Nightwatch is a rank tracking platform that charges by keywords tracked rather than by user seats, and, on current plans, tracks visibility in AI assistants as well as in search engines.

Pros and Cons

Positions are tracked daily on Google, YouTube, Bing, Yahoo, DuckDuckGo, and Google Maps, by location and device, and the AI side covers ChatGPT, Claude, Gemini, Perplexity, AI Mode, and AI Overviews. Every plan includes unlimited users. API access starts on the Professional plan, so the entry plan is dashboard-only.

Engines and integrations

Site audits and Google Analytics integration come with every plan, and the Professional plan adds a Looker Studio connector, white-label reports, and the API. The Agency plan adds custom API rate limits.

Pricing

Plans are billed in euros, monthly or yearly, and differ by keywords tracked, from 500 on Starter to 20,000 or more on Enterprise. Every plan comes with a 14-day full-feature trial and no card.

DataForSEO

DataForSEO sells SEO data through APIs only. SERP API, Keyword Data API, Backlinks API, and others share one account and one pay-as-you-go balance.

Pros and Cons

You pay per SERP, not per plan, so a tracker checking 1,000 keywords daily costs exactly 30,000 SERPs a month with no keyword cap to grow into. The cheapest queue is asynchronous. You post a task, and the result arrives minutes later through a callback or a second request, which is fine for daily tracking and wrong for anything interactive.

Queues and turnaround

The SERP API bills per SERP of 10 results, and the price depends on the queue. Standard Queue averages around 5 minutes with a 45-minute target, Priority Queue averages about a minute, and Live Mode returns within about 6 seconds. Location, language, and device are request parameters.

Pricing

Pay as you go with a prepaid balance and a minimum top-up, no subscription. Per-SERP prices rise with each faster queue, and a free account gives access to the API playground for testing.

Bright Data

Bright Data is a web data platform with proxy networks, scrapers (Web Unlocker, Scraping Browser, Web Scraper API), and ready datasets under one account, and its SERP API is the part relevant here. For a tracker, the SERP API alone is enough.

Pros and Cons

The SERP API returns parsed results with location targeting through Bright Data’s proxy network, and you pay only for successful requests with unlimited concurrency. The con is that rank tracking is one use of a general SERP API, so positions, history, and alerts are yours to build.

Pricing

There is a free tier of 5,000 requests a month with no card. Beyond that, pay as you go is billed per 1,000 successful requests, and a monthly plan includes a fixed request volume at a lower rate, with additional requests billed on top. Enterprise plans are custom.

Conclusion and Takeaways

If you want a dashboard and the API is a bonus, choose the plan that includes the API at your keyword count. Authority Labs, SE Ranking, and SheerSEO open it on every plan, Nightwatch from Professional, Accuranker from Expert, and Semrush on Advanced only. If you are building the tracker yourself, compare per-request prices at the volume you will run, which for 1,000 keywords checked daily is 30,000 SERPs a month, across HasData, DataForSEO, Bright Data, and GeoRanker’s API. Owning the raw table also lets you join positions with Search Console clicks and your deploy log, which no dashboard does for you. Every provider on this list offers a free way to test except Accuranker, so run your own keywords through two or three of them before committing to a year. I would start with HasData, Bright Data, and DataForSEO on the same 20 keywords on the same day, since all three can be tested without paying, and compare the positions they return before reading a single plan page.
