AI Crawler Policy
At least one AI crawler (such as GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot or Google-Extended) appears to be blocked by robots.txt.
Issues Found
- At least one user-agent has Disallow: / which blocks the entire site.
Recommendations
- Avoid blocking the entire site (Disallow: /); restrict only sensitive or low-value paths instead.
- Review your AI crawler policy for GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot and Google-Extended to ensure it matches your content strategy.
- Consider adding explicit Allow rules for important sections to clarify crawling intent for complex setups.
- Ensure important pages, CSS and JavaScript assets are crawlable so search engines can fully render your site.
