Audit Content for LLM Readability
Analyze how well your content is structured for consumption by large language models and AI search engines.
Check AI Crawler Access to Your Site
Verify whether AI search crawlers like GPTBot, ClaudeBot, and PerplexityBot can access and index your content.
Quick answer: Use the GEO tool through ToolRouter to check ai crawler access to your site directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolAI-powered search engines are sending their own crawlers to index the web -- GPTBot for ChatGPT, ClaudeBot for Claude, PerplexityBot for Perplexity. If your robots.txt blocks these crawlers, your content is invisible to AI search. Many sites block them without realizing the traffic implications.
The check_ai_crawlers skill tests whether major AI crawlers can access your site. It checks robots.txt rules, response codes, and any explicit blocks that would prevent AI indexing. You get a clear pass/fail for each crawler.
This is the first step in any Generative Engine Optimization (GEO) strategy. Before optimizing content for AI discovery, you need to confirm the crawlers can reach it. A single misconfigured robots.txt rule can make your entire site invisible to AI search results.

Claude approaches AI crawler verification with analytical thoroughness, testing each major bot against your site and explaining the specific robots.txt rules or server responses causing blocks. It follows up with questions about your GEO goals to recommend exactly which crawlers to prioritize and what changes will have the most impact.
How to check ai crawler access to your site
Once connected (see setup above), use the GEO tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Ask Claude: "Check if AI crawlers can access my site using the geo tool" and provide your URL
- Claude tests access for all major AI crawlers
- Review which crawlers are blocked and which have access
- Ask Claude to suggest robots.txt changes if crawlers are blocked
Example prompt
Try this with the GEO tool
Check whether GPTBot, ClaudeBot, and PerplexityBot can crawl https://mysite.com. I want to make sure my content appears in AI search results.
Tips
- Run this check after any robots.txt changes to avoid accidentally blocking AI crawlers
- Some CDN and security tools block AI crawlers by default -- check your WAF rules too
- Allowing AI crawlers is the prerequisite for all other GEO optimization work
Frequently Asked Questions
How do I check ai crawler access to your site with an AI assistant?
Verify whether AI search crawlers like GPTBot, ClaudeBot, and PerplexityBot can access and index your content. Connect the GEO tool to Claude, ChatGPT, Microsoft Copilot, and OpenClaw through ToolRouter, then ask the assistant in plain language. For example: Ask Claude: "Check if AI crawlers can access my site using the geo tool" and provide your URL Claude tests access for all major AI crawlers
