AhrefsSiteAudit: what it is, its IP ranges, and how to block it

AhrefsSiteAudit is Ahrefs's SEO crawler.

Vendor	Ahrefs
What it is for	SEO tool
In its User-Agent	`AhrefsSiteAudit`
Verified by	Published addresses
Its vendor's address list	`https://api.ahrefs.com/v3/public/crawler-ip-ranges`
IP ranges	81
By default	Let through

It maps a site's pages and links for its customers' SEO reports, and sends nobody back. Bot Protection lets it through by default; you can block it.

How to verify it

Any bot can write AhrefsSiteAudit in its User-Agent. A request is AhrefsSiteAudit only when its address is in Ahrefs's published list below: check the address, not the name.

How to block it

With robots.txt, you ask it to stay out:

User-agent: AhrefsSiteAudit
Disallow: /

robots.txt is a request, not a block, and it cannot tell the real crawler from a bot wearing its name. Bot Protection verifies AhrefsSiteAudit by its address on every request and answers it as you choose on the Set-up page, per kind or for AhrefsSiteAudit alone; a bot that only wears the name is judged like any other bot.
