The Reality of AI Bot Access
Your robots.txt file might say one thing, but CDNs, firewalls, and security systems often tell a different story.
Many websites are unintentionally blocking AI bots at the infrastructure level, and consequently, they are missing out on the advantages that AI can offer for increasing their online visibility.
- CDN-level blocking
- Firewall rules
- Rate limiting
- Geographic restrictions
What We're Testing
This tool simulates requests from the actual AI bot user agents that power modern AI search and chat systems.
OpenAI Bots:
GPTBot, ChatGPT-User, OAI-SearchBot - Powers ChatGPT's web browsing
Anthropic Bots:
ClaudeBot, Claude-User - Used by Claude AI for web access
Perplexity Bots:
PerplexityBot, Perplexity-User - Powers Perplexity AI search
Interpreting Your Results
Understanding your AI bot accessibility is crucial for modern SEO strategy.
Full access: Bot can crawl and potentially reference your content
No access: Missing AI visibility opportunities
Connection failed: Often indicates bot-specific blocking at server/CDN level. Missing AI visibility opportunities
Pro tip: AI bots respect robots.txt but may be blocked elsewhere. Check both policies and actual access.

Technical Implementation Notes
Common Blocking Scenarios:
- 403 Status + Allowed in robots.txt: CDN/firewall blocking
- Connection errors: Bot-specific server rejection
- Different responses per bot: User-agent based content serving
Testing Limitations:
- Results may vary by geographic location
- CDN caching can affect consistency
- Rate limiting may impact subsequent tests
- Bot behavior documentation is often incomplete
Note: Bot purposes are based on official documentation where available and observed behavior patterns. Companies rarely provide complete technical specifications for their crawlers.
