What AhrefsBot does
AhrefsBot crawls the web automatically to build the Ahrefs database, which also powers the Yep search engine. It obeys robots.txt and Crawl-delay for HTML pages; when rendering JavaScript it may fetch several assets at once. It is not triggered by individual users.

FAQ
Questions about AhrefsBot
Does blocking AhrefsBot affect Google rankings?
No. AhrefsBot only feeds Ahrefs and Yep; Google uses its own crawler, Googlebot.
Does AhrefsBot obey Crawl-delay?
Yes, for HTML pages. Ahrefs notes crawl-delay cannot be followed when rendering JavaScript, so asset requests may arrive more often.
How do I verify AhrefsBot?
Check that reverse DNS ends in ahrefs.com or ahrefs.net, or match the IP against the ranges at api.ahrefs.com/v3/public/crawler-ip-ranges.
