Free AI SEO Checker: Can AI Crawlers Read Your Site?
Check your website for AI crawler access rules and technical barriers that may prevent AI search systems from reading your content.
Check AI access
No sign-up or email required. Three checks per day. Simulated crawler requests cannot prove that a real AI service can access or cite your site.
What does this AI SEO checker check?
It checks robots.txt rules for AI crawlers, the presence of llms.txt, a sitemap declaration and page indexing restrictions. It also compares browser and simulated crawler responses to highlight possible access barriers. This is an AI overview checker for technical readiness, not a tracker of actual Google AI Overview appearances.
| What it covers | How to use the result |
|---|---|
| robots.txt | Access rules for named AI crawlers and a sitemap declaration. |
| Simulated requests | Browser, GPTBot and PerplexityBot HTTP responses, with inconclusive results identified. |
| Indexing barriers | A noindex directive on the readable page, excluding security challenge pages. |
| llms.txt | Whether a readable file is found, missing or cannot be verified. |
Frequently Asked Questions
Is this an AI Overview ranking checker?
It checks technical readiness rather than rankings or citations. It does not search Google AI Overviews to see whether your brand appears. Use the findings to investigate access barriers, then check actual visibility separately.
Does an accessible site automatically appear in AI answers?
No. Access is only one part of discovery, and each service chooses what it uses or cites. A clean report is not a promise of inclusion in ChatGPT, Gemini or Google AI Overviews.
What does an inconclusive crawler test mean?
A security layer may treat our simulated request differently from a real crawler. Rate limits and challenge pages can prevent a reliable comparison. Review the robots.txt results and your server settings before deciding that an AI crawler is blocked.
Is llms.txt required for AI visibility?
This tool checks for llms.txt as a discoverability signal. Its presence does not guarantee that any service will use it. A missing file alone does not prove that AI systems cannot read your website.
Is the AI SEO checker free?
Yes, you can run three checks per day without an account. Enter a public website or page URL to get the report on this page. No email address is needed.
