AI Crawlers Are Scanning Your Site Right Now - How to Check and Control Access

AI crawlers now appear in many server logs alongside traditional search bots.

Some are used for search retrieval, some for training, and some for broader web

indexing. If you care about AI search visibility, you need to know which ones

can access your public pages.

The most common accidental blocker is simple: a robots.txt rule or CDN bot

setting that prevents AI crawlers from reaching the content you want discovered.

The major AI crawler tokens to check

Here are crawler tokens you may see in logs or robots.txt rules:

Crawler names and purposes change. Always confirm against official platform

documentation before making sitewide access decisions.

First, check what is actually happening

Before you change anything, find out who is already crawling. If you have server

logs:

grep -E "GPTBot|OAI-SearchBot|ChatGPT-User|ClaudeBot|Claude-SearchBot|Google-Extended|CCBot|PerplexityBot" access.log

If you use Cloudflare, check bot and security events and filter by user agent.

Three quick diagnostic steps:

1. Open https://yourdomain.com/robots.txt and look for broad Disallow: /
   rules.


2. Confirm the sitemap is listed in robots.txt or discoverable at
   /sitemap.xml.


3. Use our to audit these signals in one scan.
   
   
   

   
   
   
   The bottom line
   

   
   
   

   Most accidental AI crawler blocks come from broad robots.txt rules or CDN bot
   
   settings. Both are fixable. The right setup is not "allow everything forever";
   
   it is to make public discovery intentional and private areas truly private.
