Ahrefs Site Audit
Overview
What Ahrefs Site Audit does
Ahrefs Site Audit is the crawling module of the Ahrefs SEO platform. It fetches your pages from the cloud, checks them against a large set of predefined rules covering performance, HTML tags, content quality, redirects, links, and indexability, and rolls the results into a single Health Score you can track over time. Issues are labeled Errors, Warnings, and Notices so you know what to fix first.
Key reports and how it works
The tool includes visual reports many crawlers lack: a crawl-depth and internal-link view, an orphan-pages report drawing on other Ahrefs indexes, and charts for status codes and page performance. You can schedule automatic recrawls, compare crawls to see what changed, and filter issues by segment. Because it runs in the cloud, large sites can be audited without tying up a local machine.
How we use it in SEO projects
For our SEO and technical SEO clients, Ahrefs Site Audit pairs crawl data with the backlink and keyword data already in Ahrefs, so one platform connects technical health to ranking performance. Our team uses the Health Score and change tracking to report progress plainly to clients and to verify that a fix deployed by developers cleared the underlying issue rather than just hiding it.
