Free Domain Authority Checker
Enter any domain to check its authority score, free and no login. The score is Ahrefs Domain Rating (DR), the 0-100 authority metric most link builders quote and the closest equivalent to Moz Domain Authority (DA).
What is Domain Authority?
Domain Authority is a 0-100 score that predicts how well a website can rank, based on the strength of its backlink profile. Moz coined the term, but it has become the generic phrase for website authority, and every major SEO toolset has its own version. None of them is a Google metric; all of them estimate the same underlying thing Google rewards, which is links from strong, relevant sites.
DA vs DR: the two authority scores
Moz DA and Ahrefs DR are the two scores you will hear quoted. Both run 0-100, both are logarithmic and both measure backlink strength, from different link indexes, so the numbers rarely match exactly but rank sites in nearly the same order. This checker reports Domain Rating because Ahrefs runs the larger link index and DR is the number the link-building market prices against.
What is a good Domain Authority score?
0-10: Very low authority. A brand-new or near-invisible domain. Every quality link counts.
11-30: Low authority. Some footing. Consistent, niche-matched links compound fast from here.
31-50: Medium authority. Established. You can compete for mid-competition keywords with the right links.
51-70: Strong authority. A real player. Links from peers at this level move the needle most.
71-100: High authority. Top-tier. A link from here passes serious weight to whoever you point at.
FAQ
What is a good Domain Authority score?
Authority scores are relative, not pass or fail. Under 10 is a brand-new or near-invisible site, 10-30 is typical for a small site or blog, 31-50 is established, 51-70 is strong and above 70 is top-tier. What matters is how you compare to the sites outranking you for your keywords, not the absolute number.
Is Domain Authority a Google ranking factor?
No. DA and DR are third-party estimates, by Moz and Ahrefs, of how strong a site's backlink profile is. Google does not use either score. They still correlate with ranking ability because they measure the thing Google's link systems reward: links from strong, relevant sites.
What is the difference between DA and DR?
Both score a domain's backlink strength from 0 to 100 on a logarithmic scale. DA is Moz's metric, DR is Ahrefs'. They use different link indexes and formulas so the numbers differ a little, but they track each other closely. This tool reports DR, the score most link builders quote.
How do I increase my Domain Authority?
Earn dofollow links from real sites that have authority of their own, ideally in your niche. The scores are logarithmic, so moving from 40 to 50 takes far more link equity than moving from 10 to 20. Steady links from relevant sites beat bursts of low-quality directory links every time.
