Robots.txt Analyzer
Check which AI bots and crawlers can access your website content.
How robots.txt controls crawler access to your website
The robots.txt file is one of the most important — and most misunderstood — files on any website. It tells search engines and AI crawlers which pages they can and cannot access.
A misconfigured robots.txt can block Googlebot from indexing your content or prevent AI assistants like ChatGPT from reading your pages.
Crawlfind's Robots.txt Analyzer checks your file against all major search engine and AI crawlers to identify blocking issues before they affect your visibility.
- Robots.txt controls which bots can crawl your site
- AI bots like GPTBot and ClaudeBot respect robots.txt rules
- Blocking crawlers can prevent your content from being indexed or cited
- Misconfigured robots files are one of the most common SEO mistakes
If you want to go further, run a full SEO & AEO audit to identify technical issues across your entire site.
Key facts about robots.txt
Robots.txt controls bot access
This plain text file at your domain root tells crawlers which URLs they are allowed or disallowed to visit.
AI bots respect robots.txt rules
GPTBot, ClaudeBot, PerplexityBot and other AI crawlers follow robots.txt directives. Blocking them means your content won't appear in AI answers.
Blocking bots can prevent indexing
If you accidentally block Googlebot or other search crawlers, your pages will not appear in search results.
Misconfigured robots files harm SEO
Common mistakes like blocking CSS/JS resources or using overly broad disallow rules can significantly reduce your search visibility.
