Domain Authority
Also known as: DA, Domain Rating
Domain Authority is a third-party score (1–100) that predicts how well a website is likely to rank, based largely on the quantity and quality of its backlinks.
Domain Authority (and the similar Domain Rating) was created by SEO tool vendors like Moz and Ahrefs — it is not a metric Google uses or endorses. It's a useful relative benchmark, not a direct ranking factor.
The score is logarithmic: climbing from 20 to 30 is far easier than from 70 to 80. Use it to compare your site against competitors and to track the trend of your link profile over time, rather than as an absolute target.
Because it's driven mostly by backlinks, raising domain authority means earning quality links — the off-page work that complements strong on-page and technical SEO.
