What It Checks
Our robots.txt checker analyzes your file for AI-specific crawler rules including GPTBot (ChatGPT), ClaudeBot (Anthropic), Google-Extended (Gemini), PerplexityBot, and others. It checks for overly restrictive rules, crawl delays, sitemap declarations, and TDM Protocol compliance.
Why It Matters
Your robots.txt directly controls which AI systems can access your content. Blocking AI crawlers means your pages won't appear in AI-generated responses. Many websites unknowingly block important AI bots, losing visibility in the fastest-growing search channel.
How to Fix Issues
Review your robots.txt for User-agent rules that target AI bots. Decide which AI crawlers you want to allow and update rules accordingly. Add your sitemap URL. Consider adding TDM-specific headers if you want to control AI training access separately from inference access.
Frequently Asked Questions
Which AI bots should I allow in robots.txt?
At minimum, consider allowing GPTBot (ChatGPT/OpenAI), Google-Extended (Gemini), ClaudeBot (Anthropic), and PerplexityBot. These are the major AI systems that drive referral traffic back to your site.
Can I allow AI bots to read but not train on my content?
Yes! The TDM (Text and Data Mining) Protocol allows you to permit inference access while restricting training. GEOAudit checks for TDM-Reservation headers and ai.txt compliance.
Does blocking AI crawlers affect my Google ranking?
Blocking Google-Extended only affects Gemini/AI Overview access — not your traditional Google Search ranking. However, blocking Googlebot itself will impact both. Each AI bot user-agent is independent.
How do I test if my robots.txt changes work?
Use this free checker to scan your site after making changes. It will show you exactly which AI bots are allowed or blocked and flag any potential issues with your configuration.
