Domain Authority Checker
Enter a domain and get its authority score with the backlink profile behind it — how many unique sites link to it and how many links they send. Works for your site and any competitor's.
What the score means
The score summarizes the strength of a domain's backlink profile on a 0–100 scale (the underlying provider rank is 0–1000; we show both). It is comparable across domains: a 40 out-muscles a 25 in the same niche. Different tools compute different scores — compare within one tool, never across tools.
Referring domains beat raw links
A thousand links from one site count as one vote; a hundred links from a hundred sites count as a hundred. Watch the referring-domains number first — it is the one that moves rankings, and the one both Google and AI assistants read as trust.
