Moz helped shape modern SEO, and its Domain Authority score became a shorthand many marketers still use to gauge a site's competitive strength. The platform covers the familiar range — keyword research, link explorer, rank tracking and technical audits — with a focus on accessibility for less technical users.
Domain Authority, like Ahrefs' Domain Rating, is a third-party estimate on a 0–100 scale, not a Google ranking factor. It is best used to compare sites relative to each other over time, not as an absolute target.
