What Is AhrefsBot?
AhrefsBot is a web crawler used by the SEO tool Ahrefs. It travels across the internet, visits web pages, and collects data that Ahrefs shows in its reports.
Definition
AhrefsBot is the software robot, also called a bot or spider, that Ahrefs uses to:
- Find new web pages
- Check links between pages
- Measure how strong a website looks online
- Update Ahrefs tools like Site Explorer and Backlink reports
In your server logs the user agent usually looks like AhrefsBot.
Why AhrefsBot Matters
AhrefsBot matters for website owners and SEO specialists because it:
- Helps you see who links to your site
- Provides SEO metrics like Domain Rating and URL Rating
- Shows which pages and keywords bring traffic
- Can use your server resources when crawling many pages
Understanding AhrefsBot helps you manage crawl activity and get better value from Ahrefs data.
How AhrefsBot Works
AhrefsBot follows a simple process:
- Starts from a list of known URLs
- Checks if the site allows crawling in the
robots.txtfile - Downloads allowed pages
- Reads links and finds new pages to crawl next
- Sends the collected data to Ahrefs servers for analysis
If your robots.txt blocks AhrefsBot, it will not crawl those blocked pages.
