Should You Block AhrefsBot?

AhrefsBot builds Ahrefs's commercial SEO database. Blocking it has no impact on your search rankings but may affect your site's data in Ahrefs's tools.

Blocking is reasonable to reduce server load, especially if you don't use Ahrefs's SEO tools.

Blocking Methods

1robots.txt

High for cooperative crawlers

Add a Disallow rule for AhrefsBot's user-agent string in your robots.txt file. This is the standard, cooperative method that well-behaved crawlers respect.

2Server-side UA filtering

High

Configure your web server (nginx, Apache, Cloudflare) to reject requests matching AhrefsBot's user-agent patterns. This blocks at the network level before your application processes the request.

3Switch Journey Workflows

Highest — granular, real-time control

Create a custom journey in Switch that detects AhrefsBot and routes it to a block action, challenge, redirect, or modified content — without touching your server configuration.

robots.txt — Block AhrefsBot

Add the following to your robots.txt file (at the root of your domain) to block AhrefsBot:

User-agent: AhrefsBot
Disallow: /

User-agent: ahrefsbot
Disallow: /

robots.txt — Allow with Restrictions

Alternatively, allow AhrefsBot on most pages while blocking specific directories:

User-agent: AhrefsBot
Disallow: /private/
Allow: /

User-agent: ahrefsbot
Disallow: /private/
Allow: /

AhrefsBot User-Agent Strings

Yes, AhrefsBot respects robots.txt directives. Adding a Disallow rule for its user-agent will prevent it from crawling blocked paths.

Can I allow AhrefsBot on some pages but not others?
