Website authority checker

Enter a domain to get an AIGROW Authority Score from 0 to 100. Our own estimate uses public Common Crawl link-graph ranks. Free, with no account needed.

This snapshot uses Common Crawl only. No live crawl or AI calls.

Enter a domain or a URL. We check the main domain, including for subdomains.

Free, no account. Ten checks per hour.

The free Website Authority Checker estimates a domain’s relative strength from public Common Crawl link-graph ranks. It returns our own AIGROW Authority Score, from 0 to 100, with the source rank and edition. This estimate does not predict search rankings or whether an AI assistant will recommend your business.

How the authority estimate works

Public data, stored locally
This snapshot uses Common Crawl only. We keep its top two million domain positions by harmonic centrality, a measure of connectivity in the observed link graph. Tranco popularity data is not included. This is a limited public-data lookup, not a complete backlink index.
One domain, not one page
We check the registrable domain, using the public suffix list. A URL such as shop.example.co.uk/page is checked as example.co.uk. Paths and subdomains do not get separate scores. The lookup does not visit your website.
A score you can reproduce
The Common Crawl rank is scaled logarithmically between 100 at rank one and 0 at the stored cutoff, then rounded to a whole number. Compare scores using the same source edition and stored cutoff.
Missing data stays missing
A domain outside the stored range gets no score. This means we did not find enough links in this lookup, not that the domain has no backlinks. The result shows the Common Crawl edition, stored cutoff and whether a rank was found.

Source score formula: 100 * (1 - ln(rank) / ln(cutoff))

Source: Common Crawl

About this authority checker

If you searched for a domain authority checker or a DR checker, the distinction matters: Domain Authority is Moz’s metric and Domain Rating (DR) is Ahrefs’ metric. This tool returns only the AIGROW Authority Score, using a different dataset and formula. The scores are not interchangeable.

It summarizes the rank found in our public-data lookup. Common Crawl harmonic centrality reflects a domain’s connectivity through direct and indirect links in its crawled graph. The score does not measure content quality, count all backlinks, or estimate visits.

We store a limited range of public ranks. A smaller or newer site may fall outside it, and some sites are not represented in this snapshot. We show a missing-data answer instead of assigning zero. Zero can be a valid score for a domain found near the stored cutoff.

No. The score does not test an AI assistant or measure mentions. Run the free AI visibility scan to see how your business appears in the answers it checks. Neither a score nor a scan can guarantee a future recommendation or search ranking.

The result shows the Common Crawl release used by the stored snapshot. It is not a live backlink crawl. Checking is free, with no email or account required, and limited to ten requests per hour per visitor address. No paid data service or AI model is called by this checker.
