Question 1

Does llms.txt help my Google rankings?

Accepted Answer

No. Google has publicly stated it doesn't use the file. Your Google visibility depends on the quality, structure and authority of your actual pages.

Question 2

Does ChatGPT use llms.txt?

Accepted Answer

There's no evidence it does. Studies of real AI-crawler behaviour show ChatGPT's crawlers rarely request the file, and OpenAI has not committed to using it as a signal.

Question 3

Does Perplexity use llms.txt?

Accepted Answer

Logs show PerplexityBot requesting the file at negligible rates. There's no confirmation it influences which sources Perplexity cites.

Question 4

Is llms.txt the same as robots.txt?

Accepted Answer

No. robots.txt tells crawlers which parts of your site they may access. llms.txt is meant to point AI tools to your best content. It can't block anything, and unlike robots.txt, it isn't widely honoured.
