Frequently Asked Questions
What is Domain Authority (DA) and Domain Rating (DR)?+
Domain Authority is a general term for how 'authoritative' a website looks to search engines based on its backlink profile. This tool reports Domain Rating (DR) from Ahrefs — a 0-100 logarithmic score that compares the strength of a domain's backlink profile to the most-linked sites in Ahrefs' database. A higher score indicates more and stronger referring domains.
Is this DA checker really free?+
Yes. It uses Ahrefs' free Domain Rating API, so you can check any domain at no cost and without an account. To keep the service available for everyone, checks are rate limited to 10 per minute.
What is a good Domain Rating score?+
DR is logarithmic, so moving up gets harder at the top. As a rough guide: 0-20 is a new or low-authority site, 20-40 is growing, 40-60 is established, and 70+ is a strong, well-linked domain. Always judge DR relative to competitors in your own niche rather than against the whole web.
Why is DR a logarithmic score?+
On a logarithmic scale, the difference between DR 20 and DR 30 represents far fewer backlinks than the difference between DR 70 and DR 80. This reflects reality — earning links to push an already-strong site higher is much harder than improving a new one, so the score grows slowly at the top.
Does a higher DR guarantee better Google rankings?+
No. DR only measures backlink strength — it is not a Google metric and ignores content quality, search intent, technical SEO, and on-page relevance. It's a useful signal for comparing authority, but rankings depend on many factors beyond backlinks.
