# Check your site

Paste your website address. In a few seconds you get a score for what AI search engines and agents can read on it, and one plain fix for each thing that is missing.

## What it looks at

- Whether GPTBot, ClaudeBot, PerplexityBot, Google-Extended and CCBot are allowed in robots.txt
- Whether there is an llms.txt, and whether it is valid
- The sitemap
- JSON-LD structured data on the home page and up to ten pages it links to
- Whether the main text is in the page itself and not added by JavaScript
- The title, description and canonical link on each page

## How it behaves

It reads only public pages: at most 11 pages and a few small files, each fetched once, plus any redirects it follows (three at most for each). It reads robots.txt first and does what it says. It refuses private and internal addresses, and each visitor can run 5 checks a minute. This page does not save the address you type or the report.

## For agents

The same check is a tool for Claude, ChatGPT and other agents. Point an MCP client at https://superintelligentfoo.com/mcp and call check_site with a url. Or call the JSON address directly: https://superintelligentfoo.com/api/check?url=example.com
