Domain Authority
A 0–100 score estimating how likely a whole website is to rank. Higher is harder to beat.
Domain Authority (DA) is a 0-to-100 score — created by SEO tools like Moz, with similar versions from Ahrefs and Semrush — that estimates how likely an entire website is to rank in search results. A brand-new site sits near 1; sites like Wikipedia approach 100.
Important: DA is not a Google metric. Google has never confirmed using it. It's a useful third-party estimate, mostly driven by the quantity and quality of a site's backlinks.
How to use it
Treat DA as a comparison tool, not a goal. Before you target a keyword, check the DA of the pages already ranking. If they're all 70+ and you're at 15, pick an easier long-tail fight instead. Chasing the DA number itself is a distraction — rankings and traffic are what pay the bills.
