Check robots.txt, sitemap and llms.txt

The most important free LLM readiness check: robots.txt, sitemap and llms.txt.

What is measured here

This module checks whether the domain provides a robots.txt, a sitemap and LLM-relevant files such as llms.txt or llms-full.txt. It also detects whether known AI bots are blocked, allowed or not mentioned in robots.txt.

Why this module matters for AI / LLM visibility

This section is exactly what makes an AI visibility check different from an ordinary website scan. If AI visibility matters, you need to know whether content is accessible to ChatGPT Search, Claude Search, Perplexity or other crawlers at all.

What the free online version can already check here
  • status of robots.txt, sitemap and llms.txt
  • initial AI crawler access assessment
  • warning for missing or conflicting signals
What the full version adds
  • bot-level rule analysis by crawler and purpose
  • recommendations for separate search / user / training strategies
  • matching with logs and real visibility experience
Demo evaluation for the most recently checked URL

If you already checked a URL on the main page, CheckCom shows a live or demo evaluation for this exact module here. Without a previous check, a sample result is loaded automatically.

Note: the free web demo only checks signals that can be measured online quickly and sensibly. Expensive provider, model or market runs remain part of the premium version.
