FAQ

Questions about domain authority checker

A score that estimates how strong a domain's backlink profile is, so how likely its pages are to rank. Each SEO index computes its own. Moz calls its score Domain Authority, others call it domain rank or domain rating, and the numbers do not convert into each other.

DataForSEO domain rank, from the DataForSEO backlink index. It scores every domain in DataForSEO's link graph from 0 to 1000, with a method similar to PageRank: links from domains that themselves have many strong links count more.

No. Moz Domain Authority is Moz's own 1 to 100 score from Moz's own index. This page shows DataForSEO's rank on a 0 to 1000 scale. Compare domains with the same score only.

There is no fixed bar. Compare your domain with the sites that rank for the keywords you want. Referring domains often say more than the score: a few hundred real sites linking to you is a solid base.

The number of different websites that link to the domain. Ten links from one site count as one referring domain, which is why it is a better signal than the raw backlink count.

DataForSEO's estimate, from 0 to 100, of how much of the domain's link profile looks spammy. A high score is a reason to look at the links before you trust the rank.

Earn links from relevant sites that already rank: useful tools, original data and pages other writers cite. The score follows the links, so there is no shortcut on the score itself.

Yes. Each run on this page costs you nothing and is limited per hour. For many domains, your agent runs the same endpoint on your own looot account at the per-call price shown above.

Copy the prompt above into your agent with the looot skill.md link. It picks the backlink summary endpoint, checks the price and returns one row per domain.
