Ahrefs SEO Checker & API: Bulk DR, Backlinks & Traffic
All-in-one Ahrefs checker for lists of domains, page URLs and keywords. One run gives each site its Domain Rating (DR), backlinks, referring domains, dofollow share, the top 20 backlinks with anchors, organic traffic and traffic value, top pages, top countries and keywords, competitors and a 12-month history, and each keyword its Keyword Difficulty (KD), search volume and SERP. Turn on the tracker to see what changed since the last run.
No Ahrefs account, no API key, no captcha tokens, no browser setup on your side. Works on the free Apify plan. Use it as a bulk Ahrefs SEO checker, an Ahrefs API alternative for SEO reports, competitor research, link prospecting and keyword research.
What you get
One row per domain or URL. Real example, 24 October 2026:
| target | DR | backlinks | referring domains | dofollow | organic traffic | traffic value | keywords |
|---|---|---|---|---|---|---|---|
| ahrefs.com | 91 | 25,265,945 | 118,384 | 58% | 3,028,432 | $5,300,727 | 135,500 |

| backlinko.com/seo-checklist (page) | 90 | 1,104 | 474 | 82% | 899 | $2,207 |
Each domain row also carries lists: topBacklinks (linking page, its DR, anchor, linked URL), topCountries, topKeywords, competitors, trafficHistory and referringDomainsHistory, and topPages when you turn them on.

How it works
| Step | What happens |
|---|---|
| 1. Free index | Each domain is looked up in the Ahrefs Top index by plain HTTP: fast and cheap |
| 2. Live checks | Backlinks, top pages, keyword difficulty, ideas and sites missing from the index are checked live in Ahrefs' own free tools. The Actor passes their human check itself, so you pay nothing extra for captcha solving |
| 3. One row | Everything about a domain, URL or keyword goes into one row, pushed as soon as it is ready |
| 4. Tracker | With Track changes on, the numbers and top backlinks are remembered under the tracker name and compared on the next run |

Pricing
Pay per event:
| Event | Free / Starter | Scale | Business |
|---|---|---|---|
| Result (one domain, URL or keyword with data) | $0.00499 | $0.00449 | $0.00399 |
| Live check (backlinks, top pages, a site missing from the index, KD, ideas) | $0.006 | $0.006 | $0.006 |
| Run start (per GB of memory) | $0.003 | $0.003 | $0.003 |
Examples on the Free plan, default 2 GB memory:
| Run | Cost |
|---|---|
| 1,000 popular domains, DR and traffic only (backlinks off) | $0.006 + 1,000 × $0.00499 = ~$5.00 |
| 100 domains with backlinks and top 20 backlinks | $0.006 + 100 × ($0.00499 + $0.006) = ~$1.10 |
| The example: 1 domain + 1 page with backlinks, 1 keyword with ideas | $0.006 + 3 × $0.00499 + 5 × $0.006 = ~$0.051 |
| Weekly tracker of 10 competitors with backlinks | ~$0.12 a run |
Rows with no Ahrefs data, unknown keywords, invalid entries and failed live checks are free. Set a maximum cost per run in Console and the Actor stops at it.
Speed and memory
The free index answers in under a second per domain. Live checks run in a browser: 1 at a time with the default 2 GB (2-3 checks a minute), 2 with 3 GB, 6 with 4 GB. The price per check is the same; more memory only adds the run start fee per GB. Give API and agent calls a timeout of 180+ seconds when they include live checks.

FAQ
Are the numbers the same as on ahrefs.com? Yes. Index data comes from Ahrefs Top (Ahrefs' free website rankings, updated monthly), live data from Ahrefs' free tools at the time of the run.
Why do some domains have no backlinks list or top pages? Those come from live checks: turn on Backlinks or Top pages. Domains from the free index always have DR, referring domains, traffic, keywords, countries and competitors.
How many backlinks per site? Up to 20 top backlinks, one per linking domain, as in Ahrefs' free Backlink Checker. The totals cover the whole profile.
Is this the official Ahrefs API? No. The official Ahrefs API needs a paid Ahrefs plan with API units. This Actor reads the same public data Ahrefs shows in its free tools, for any number of domains and keywords, without an Ahrefs account.
What if a check fails? The row comes back with an error and is not charged. Run it again later.
Use with the API and AI agents
Call the Actor from the Apify API, Python or JavaScript clients, Make, Zapier, n8n, or as a tool for AI agents through the Apify MCP server. Input is one JSON object, output is one JSON row per domain, URL and keyword.
