What is Domain Authority?
Definition
A third-party metric (by Moz) that predicts how likely a site is to rank in search results, based primarily on the quality and quantity of its backlink profile.
In more detail
Domain Authority (DA) is a 1–100 score developed by Moz. New sites start near 0; well-established publications with thousands of quality backlinks score in the 80s–90s. Higher DA correlates with stronger ranking ability, but DA itself doesn't cause rankings — it's a proxy metric, not a ranking signal Google uses directly.
Similar metrics exist from other SEO tools: Ahrefs Domain Rating (DR), Semrush Authority Score, and Majestic Trust Flow. Each uses different methodology and weights different signals, so scores aren't directly comparable across platforms.
DA is most useful as a comparative benchmark — evaluating the quality of a potential backlink source, comparing your authority against competitors, or tracking your site's growth over a 12–24 month period as your backlink profile matures.
Why it matters
DA provides a useful shorthand for site authority in SEO conversations and reporting, but it should never be the primary goal. Chasing DA leads to gaming metrics rather than building genuine authority through quality content and real backlinks.
