Domain Authority & Website Rank Checker — Bulk, Open Data

Check the link strength and web ranking of up to 10,000 domains per run. For every domain you get a 0-100 link strength score, its Majestic Million rank with referring subnets and referring IPs, and its position in the Common Crawl web graph by harmonic centrality and PageRank. One row per domain, ready for a spreadsheet.

The numbers come from two large open datasets, kept on Apify, with the data date of each in every row. Nothing is scraped from Moz, Ahrefs, Semrush or Similarweb, so there are no logins, no bot walls and no failed runs because a website blocked the scraper.

Why this one

• 🧮 Bulk and quick. Paste a list of domains or full links: 1,000 domains took 18-26 seconds and 10,000 took 101 seconds in live test runs.
• ✅ Runs that finish. The data is already on Apify. No website is visited, so there is nothing to block the run.
• 🔗 Backlink signals you can trace. Referring subnets and IPs from the Majestic Million, link-graph ranks from Common Crawl, each with its source, licence and data date in every row.
• 🌍 Any domain name. Links, subdomains, www., ports and paths are reduced to the registered domain (news.bbc.co.uk → bbc.co.uk) with the Public Suffix List; internationalised names (bücher.de) work too.
• 💸 You pay only for domains with data. Domains that are in neither dataset and inputs that are not domains are free.

What you get

Field	What it is
domain, domainUnicode	the registered domain that was looked up (punycode), and its Unicode spelling for internationalised names
linkStrength	our 0-100 score from the two link rankings below (see how it is calculated)
majesticRank, majesticTldRank	position in the Majestic Million (1 = most referring subnets) and within its top-level domain
majesticRefSubnets, majesticRefIPs	how many distinct IP subnets and IP addresses link to the domain (Majestic)
commonCrawlHarmonicRank	position by harmonic centrality in the Common Crawl domain graph (1 = most central of ~133 million domains)
commonCrawlPageRankRank	position by PageRank in the same graph
found	true when at least one dataset has the domain
dataDates, sources	the data date of each dataset, and for every dataset used in the row: name, licence and its link
input, status, error, checkedAt	what you gave, OK / NOT_FOUND / INVALID_INPUT, why there is no result, when it was checked

A value is null when the dataset does not have the domain: the Majestic Million covers one million domains, the Common Crawl part the 20 million most central ones.

How linkStrength is calculated

Each ranking position is turned into points on a log scale, points = 100 × (1 − log10(rank) / 8): rank 1 gets 100, rank 10,000 gets 50, rank 1,000,000 gets 25, and every tenfold step down the ranking costs 12.5 points. linkStrength is the mean of the points for the Common Crawl harmonic-centrality rank and the Majestic rank (Majestic orders its million by the number of referring IP subnets), over the ones the domain has, rounded to a whole number.

It is our own score, not Moz Domain Authority, Ahrefs Domain Rating or Semrush Authority Score, and it will not match them. Those are built from private link indexes; this one is built only from open data, and every input to it is in the row, so you can check or recompute it.

Data sources and attribution

Dataset	Used for	Licence / terms	Published
Majestic Million by Majestic-12 Ltd	majesticRank, majesticTldRank, majesticRefSubnets, majesticRefIPs	CC BY 3.0	Majestic publishes it daily
Common Crawl web graph, domain level	commonCrawlHarmonicRank, commonCrawlPageRankRank	Common Crawl Terms of Use	about monthly; each release covers three months of crawls

The values are used as published; linkStrength is calculated by this Actor from them. The exact data date of each dataset is in every row (dataDates, sources).

How to use it

1. Add Domains, one per line — names or full links (a column pasted from a spreadsheet works too).
2. Press Start.
3. Download the results from the Output tab as JSON, CSV or Excel, and sort by linkStrength.

Typical uses: rank a list of link prospects or guest-post sites, compare competitors, clean a lead list by site size, or check how strong a domain is before you buy it.

You can also call it from the Apify API, from Make, Zapier or n8n, or from an AI agent through the Apify MCP server.

Pricing

You are charged per domain found — see the price on this page. Domains that are in neither dataset, inputs that are not domain names, and duplicates are free.

FAQ

Why is my domain not found? The Common Crawl part covers the 20 million most central domains on the web and the Majestic Million the million with the most referring subnets. A new site, or one with few links from other sites, is in neither — that itself tells you its link profile is still small. It is not charged.

Is this Moz DA, Ahrefs DR or Semrush Authority Score? No. Those tools do not publish their data under an open licence. This Actor gives an open, reproducible alternative built from public datasets; scores will differ.

Does it check subdomains or pages? It checks the registered domain of whatever you give: shop.example.co.uk and example.co.uk/page give example.co.uk.

What about sites on github.io, blogspot.com or vercel.app? Both datasets rank such a platform as one domain (github.io is among the top 50), not the sites on it. A site like someone.github.io is therefore reported as not found, with that reason, and not charged; it never gets the platform's numbers.

How fresh is it? The data date of each source is in every row (dataDates). Link graphs change slowly, so ranks that are a few weeks old still compare domains well.
