What is the Domain Authority Checker?

Domain authority is a third-party score that estimates how strong a website is in search, usually on a 0–100 scale. When the Open PageRank integration is active, this tool returns the domain’s Open PageRank (a 0–10 score built from Common Crawl link data) and its global rank. Without it, the tool shows only a placeholder computed from the domain name, which does not measure links; the result page says clearly which one you are looking at.

Why it matters for SEO

Authority estimates help you prioritise: which sites are worth approaching for links or guest posts, how strong competitors are, and whether an expired domain is worth buying. Google does not use any third-party authority score, but stronger sites do tend to rank more easily.

How to read your Domain Authority Checker results

Check the label on the score first. “Open PageRank × 10” is a link-based metric you can compare across domains. “Placeholder score” is not link-based and should not be used for decisions. Compare scores between domains rather than reading them in isolation, and use Moz DA or Ahrefs DR directly when you need those exact figures.

Expert tips

  • Compare yourself with the top three competitors for your main keyword.
  • Judge link prospects on relevance first, authority second.
  • Grow authority with great content and genuine links, not shortcuts.
  • Pair this with the Backlink Checker overview.

Limitations

Shows Open PageRank when that integration is active. Otherwise it shows a placeholder computed from the domain name, which does not measure links.

Guides that use this tool

Frequently asked questions

No. Domain authority scores are third-party estimates. Google uses its own signals, though sites with many quality links tend to score higher.
No. With the integration active the score comes from Open PageRank, a different link-based metric. For official Moz DA use Moz’s own tools.
If Open PageRank data is unavailable, the tool falls back to a score computed from the domain name only. It does not measure links and will not change as your site grows, so treat it as a placeholder, not a metric.
Earn links from relevant, reputable sites, publish content worth referencing and keep the site technically healthy.
