FAQ

Questions about this tool

Is this the same as Moz Domain Authority?

No. The authority score here is a 0–1000 backlink-rank score from the backlink index — directionally similar to Moz DA or Ahrefs DR, but its own metric. We label it honestly rather than claim parity with a specific vendor's number.

How accurate is the estimated organic traffic?

It's a model estimate: the keyword index multiplies each ranked keyword's position and search volume into an estimated click total. It's great for comparing domains on the same scale, not for matching a site's own analytics exactly.

What does the position split show?

How many of the domain's ranked keywords sit at position 1, positions 2–3 and positions 4–10. A site with lots of page-one rankings converts its keyword footprint into far more traffic than one stuck on page two.

Why does this cost two lookups?

The authority score comes from the backlink index and the traffic and keyword data from the search index — two different sources. We combine them into one report so you get the full picture in a single check.
