Free Domain Authority Checker

It gives your site a Website Health score from 0 to 100, based on real on-page checks: SEO basics (title, meta, headings, structured data), security (HTTPS, SSL), mobile setup, and crawlability (sitemap, robots). It then lists the highest-impact fixes first, so you know exactly what to improve.

Domain Authority (DA) and Page Authority (PA) are Moz's proprietary backlink metrics, and the only honest free data behind them is too thin to show a number you could trust. More importantly, a DA number does not tell you what to do. This Website Health score measures things you can actually fix this week, which is what improves your rankings and conversions. If you specifically need a Moz DA figure, a paid tool like Moz or Ahrefs is the right source.

A grade of A (90+) means the on-page fundamentals are solid. B (75 to 89) is good with a few quick wins. Below 60 usually means real issues that are costing you search visibility and trust. The fix list shows you the fastest way to move up.

Start at the top of the fix list, since those items carry the most weight. Common quick wins are tightening the page title and meta description, adding a clear H1 and clean heading order, enabling HTTPS, and adding a sitemap. Most are small changes you or your developer can make quickly.

This is a fast, focused on-page snapshot. For a deeper, page-by-page audit that also scores performance, design, and technology, run our full Website Analyzer. And if the fixes point to a site that is simply old or poorly built, we can rebuild it for you.

No signup required, and we do not sell your data. The check runs against publicly available information about your site, and results may be cached briefly to keep the tool fast.
