llms.txt Availability Checker
Check the optional llms.txt response. This is not a full syntax validator or an AI citation test.
Should I prioritize llms.txt or fixing my website content?
Use it to organise meaningful public documentation. Prioritise the website, navigation and sitemap first. Never publish secrets or private access links in the file.
What to do step by step
- State the product name and a factual description.
- Select current, important public pages.
- Explain the purpose of each linked resource.
- Generate links from the published content registry.
- Check the text response and every destination.

## Documentation
- [Methodology](https://example.com/methodology): What scores mean and what they do not prove.A common mistake
Llms.txt does not grant crawler permissions. Google says no special AI text file is required for AI Overviews or AI Mode. File presence does not establish eligibility or a ranking benefit.

Run your audit
When is an llms.txt file useful?
Treat llms.txt as a supplementary guide to useful documentation. Begin with a real workflow, such as helping an assistant locate an integration reference.
- Link an overview and a first-use guide.
- Include limitations and the current reference.
- Identify languages and archived versions clearly.

Which documentation links belong in llms.txt?
Each link should explain which question it answers. A short curated map is more usable than a dump of filters, announcements and duplicate URLs.
- Use “Pricing and limits” rather than “More information”.
- Link directly to the current public destination.
- Describe available features separately from planned ones.
How to keep llms.txt links current
Generate the file from an approved public-content list, or assign a manual owner. Successful generation alone does not establish that each description is accurate.
- Exclude drafts and token-bearing private links.
- Check changed product names and moved pages.
- Verify both HTTP responses and the promised content.
Does llms.txt guarantee AI citations?
Google’s AI Search guidance requires no special AI text file. Demonstrate the value of llms.txt in the particular workflow that uses it.
- Retrieve readable text without signing in.
- Test the intended tool with the maintained references.
- Keep crawler access rules in their appropriate controls.
How to verify the result
Check every listed URL after publication. Compare access with robots.txt, discovery coverage with the XML sitemap, and the document’s purpose with your AI crawlers policy. Record which tool actually consumes the file.

Frequently asked questions
Should I prioritize llms.txt or fixing my website content?
Fix inaccessible or unclear content first. A text map can help tools that choose to use it, but it cannot repair a broken URL or supply an expert answer. Generate it from the same publication registry as your sitemap and exclude private or unpublished documents.
When the task is complete
Every link reaches current public content and the description matches the product. File presence is not a confirmed citation, a crawler permission, or a measured ranking improvement.
