Domain Authority Checker
Check any domain's Open PageRank authority score.
How it works
Enter a domain (or any URL on it) and the checker queries Open PageRank — an openly published authority metric computed from real link data across the web — and returns the 0-10 PageRank decimal, the domain's global rank, and a plain-language verdict band.
Open PageRank refreshes roughly monthly, so treat the score as a slow-moving baseline: it tells you where a domain stands, and repeated checks tell you whether your link building is moving it.
The result downloads as CSV or JSON, free and instant.
Frequently asked questions
Is this the same as Moz DA or Ahrefs DR?
No — those are proprietary vendor metrics. Open PageRank is an openly published score on the same 0-10 idea, computed from public link data. The absolute numbers differ between providers; the relative comparisons are what matter.
What is a good score?
As a rule of thumb: 7+ is strong authority territory, 5-7 is established, 3-5 is emerging, and below 3 is where most new or niche sites start. Compare against direct competitors rather than the global giants.
Why hasn't my score moved after new backlinks?
Open PageRank updates roughly monthly and weights links by the authority of the linking domains. A handful of strong, crawlable placements moves the needle more than hundreds of weak ones — and either way it shows up on the next refresh, not the next day.
Know the score. Then move it.
