Moz DA checker — FAQ
What is Moz Domain Authority (DA)?
Domain Authority is a 1–100 score created by Moz that predicts how likely a website is to rank, based mainly on the number and quality of sites linking to it. It is not a Google metric — Google does not use DA — but it is a handy way to compare sites.
Can I check Moz DA for free?
Yes. Enter a domain above and use the one-click Moz link to open Moz’s own free domain analysis pre-filled with your domain. A free Moz account gives a limited number of lookups each month.
Why does this tool not show the Moz DA number directly?
Moz DA is a proprietary score that only Moz can calculate, and showing it requires Moz’s paid API. Rather than invent a fake “DA”, we show real, free signals (Open PageRank and domain age) and take you straight to the official Moz, Ahrefs and Semrush checkers.
What is a good domain authority score?
It is relative. New sites usually start at 1–10, established small business sites often sit at 20–40, and major publishers reach 80+. Compare yourself with the sites ranking for your keywords rather than chasing an absolute number.
How do I increase my domain authority?
Earn links from relevant, trusted sites: publish genuinely useful content and tools, get listed in reputable directories, write guest posts for sites in your niche, and fix broken links pointing to your site. DA rises slowly as your link profile grows.
Is Moz DA the same as Ahrefs DR?
No. Ahrefs Domain Rating (DR) and Semrush Authority Score (AS) are separate scores built from each company’s own link index, so the same site can have different numbers on each. Checking all three gives a more rounded view.
