llms.txt Checker

What is llms.txt?

llms.txt is a proposed standard (similar to robots.txt) that provides AI language models with structured information about your website. It helps AI search engines understand what your site is about, what content to prioritize, and how to cite your pages.

As AI search engines like ChatGPT, Perplexity, Claude, and Google AI Overviews become mainstream, having a proper llms.txt file is critical for AI visibility.
