What is Ahrefs Site Audit?

Consider blocking Ahrefs Site Audit only if you do not want your pages included in SEO databases. It does not influence how search engines rank you, and blocking it will not hide backlinks to your site because those are discovered on the linking sites. Almost none of the top websites we track currently have robots.txt rules for Ahrefs Site Audit.

Yes. Ahrefs Site Audit is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Ahrefs Site Audit respects it.

No. Ahrefs Site Audit can reach only public pages, and authentication prevents it from accessing private content.

Your domain appears in the ranking, backlink, or competitor data maintained by Ahrefs Site Audit's operator. A customer may be tracking your site, one of your competitors, or a backlink that connects another site to yours.

Agent Analytics tracks Ahrefs Site Audit visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Ahrefs Site Audit". Look for comprehensive site crawls that follow internal links. Because Ahrefs Site Audit does not publish a verification method, any client can claim its identity and a log match is only a clue.
