AI search engines ignore llms.txt proposal for website guidance

By PulseAugur Editorial · [1 sources] ·

A new proposal called llms.txt suggests website owners create a plain-text file at their domain root to guide AI tools to important pages. However, current evidence indicates that major AI search engines like Google do not use this file for citation decisions, with Google explicitly stating it ignores llms.txt. While some platforms like Chrome Lighthouse audit the file, it does not impact rankings, and AI tools like OpenAI and Perplexity recommend using robots.txt instead for crawler access. AI

IMPACT This proposal's ineffectiveness suggests current AI citation mechanisms rely on traditional SEO and content quality rather than explicit AI-specific directives.

RANK_REASON The article discusses a proposal for AI website guidance and its lack of adoption/effectiveness by major AI platforms, which is commentary on a potential product/standard.
