Website Authority Checker
Check any domain's authority score — computed from the open Common Crawl link graph — plus its real Chrome popularity tier. Single domain or up to 100 at once.
Quick answer
What is website authority?
Website authority is a 0–100 estimate of how strong a domain's backlink profile is compared to every other site on the web. It is computed from the link graph — how many distinct, reputable sites link to a domain — and higher scores correlate with an easier time ranking. Authority is a third-party comparison metric: Google does not use any vendor's authority score directly.
How to read your authority score
Authority scores are logarithmic: moving from 10 to 20 is far easier than moving from 50 to 60. Most small-business sites sit between 5 and 25; established niche publications typically land between 30 and 55; only heavily-linked global brands exceed 70.
Use the score comparatively, not absolutely. The useful question is never "is 34 good?" — it is "is 34 higher or lower than the sites ranking for the keywords I want?" If the top results for your target keyword all score below you, content quality decides. If they all score far above you, target longer-tail keywords first and build links in parallel.
How to increase website authority
Authority follows referring domains — the number of distinct sites linking to you — more than raw link counts. A hundred links from one directory move the needle less than ten links from ten real publications.
- Publish citable assets: original data, studies, free tools, and calculators earn links passively.
- Fix crawlability first — links to pages that redirect, 404, or noindex waste the equity they pass.
- Get listed where your competitors are: run their domains through this checker, then check their common referring sources.
- Internal linking multiplies external authority: a well-linked page passes strength to the pages it links to.
- Avoid purchased link schemes — the risk of a manual action outweighs any temporary score movement.
Bulk checking up to 100 domains
Paste up to 100 domains (one per line) to compare a full competitor set in one request — useful for prospect qualification, link-outreach triage, and agency audits. Results include each domain's authority score, global rank position, and Chrome popularity tier so you can separate strong-but-quiet domains from popular-but-weakly-linked ones.
Where this data comes from
Authority scores come from Open PageRank, an open project that computes PageRank-style scores from the Common Crawl web graph — a public crawl of billions of pages. Popularity tiers come from the Chrome UX Report (CrUX), Google's public dataset of real Chrome navigation. Both sources are public and independently verifiable; neither is an internal Google ranking factor. Scores refresh periodically as new crawls are published.
Frequently asked questions
What is a good website authority score?
There is no universal 'good' score — authority is comparative. Most small-business sites score 5–25, established niche sites 30–55, and major global brands 70+. The practical benchmark is the authority of the sites currently ranking for your target keywords: if you match or exceed them, your content and on-page quality decide the ranking.
Is website authority a Google ranking factor?
No. Authority scores are third-party estimates computed from the public link graph. Google uses its own link-based signals, but no vendor's authority number is used by Google directly. Authority scores are useful for comparing sites and estimating ranking difficulty, not as a guarantee of position.
How is this different from Ahrefs DR or Moz DA?
All three estimate the same underlying thing — backlink strength — from different crawls. Ahrefs uses its own crawler, Moz uses its Link Explorer index, and this tool uses Open PageRank scores computed from the public Common Crawl graph. Absolute numbers differ between vendors; relative comparisons between domains generally agree.
How often does the authority score update?
Open PageRank refreshes as new Common Crawl snapshots are processed, typically on a multi-week cadence. We cache results for up to seven days, so a brand-new backlink campaign can take several weeks to reflect in the score.
Why does my domain show no authority score?
Very new domains, domains with almost no external links, or domains missing from the latest Common Crawl snapshot may have no computed score yet. That usually means the site has too few referring domains to register — earning your first dozen genuine referring domains is the fix.
Can I check authority for 100 domains at once?
Yes — switch to bulk mode and paste up to 100 domains, one per line. You get authority, global rank, and popularity tier for each in a single run, free.
