Check your website’s authority in 10 seconds

Backlinks are not the whole story any more

Off-page authority tells you whether Google is likely to trust you. It says nothing about whether ChatGPT, Claude, Perplexity or AI Overviews can read your pages, understand what you sell, and cite you in an answer. Those are different problems with different fixes, and most free checkers only measure the first one.

That is why this tool checks both. A site can have a modest link profile and still be the answer an AI engine reaches for — if the structure, schema and crawler access are right.

What your score means

• 80–100

  Dominant

  One of the most linked-to domains on the web. Authority is not your constraint.

• 60–79

  Strong

  A well-established link profile. Most competitors will not outrank you on authority alone.

• 40–59

  Building

  A real footprint that is still growing. Earned links move this number fastest.

• 20–39

  Early

  Some referring domains, not yet enough to carry competitive rankings on their own.

• 0–19

  Minimal

  Almost no earned links yet. This is the single biggest lever available to you.

Exactly what we check

Eight weighted dimensions, 43 individual checks, all from your public footprint. No logins, no access to your analytics, nothing you have to install.

• Technical

  Status codes, redirects, canonicals, robots directives, mobile viewport, client-render risk

• Content

  Titles, descriptions, headings, thin pages, duplication, information gain

• Answer engines

  Question headings, answer-first blocks, extractable passages

• AI search

  GPTBot, ClaudeBot and PerplexityBot access, llms.txt, raw-HTML share, citable passages

• Schema

  JSON-LD validity, required properties, entity identity, sameAs, deprecated types

• Local

  LocalBusiness markup and NAP consistency, where the business type calls for it

• Authority

  Declared entity profiles, and the Open PageRank link-graph position

• Experience

  Author signals, credentials, an about page, freshness

Fair questions

Is this Moz Domain Authority?

No. Domain Authority is a trademarked Moz metric and only Moz can calculate it, the same way Domain Rating belongs to Ahrefs. The authority figure here is Open PageRank, an independently published score built on the Common Crawl web graph, and we show it with its source attached. The score out of 100 is our own rubric and we list every check that feeds it.

Why does my site show a low authority number?

Open PageRank measures how many other indexed sites link to you, and it follows Common Crawl. New, small or crawler-blocking sites genuinely have very few recorded referring domains. That is a finding rather than a fault, and it is usually the least urgent thing on the list — the technical and AI-readiness checks are the ones you can fix this month.

How accurate is a 10-second check?

It reads one page — your homepage — plus robots.txt and your sitemap, and it looks up your domain in the public link graph. It reports how many of its checks it could actually run, and withholds any check it could not measure rather than guessing. Checks that need several pages, like duplicate titles across a site, are marked unmeasured rather than passed.

Do you store my website data?

We keep the scan result for 24 hours so a repeat check is instant, and we do not publish it. If you unlock the full report we store the result against your email so we can follow up about it. We do not add you to a newsletter or a drip sequence, and we do not call you.
