llms.txt provided: how the world's top websites do

Of 551 of the world's most popular websites that we audited, 137 pass this check and 414 fall short.

What this check means

llms.txt is a proposed plain-text summary of a site for AI assistants. It is optional and there is no solid evidence yet that it changes how often a site is cited.

How this was measured

The figure comes from Adnave's own audits of 551 popular websites, each read as a search engine first receives it and re-checked about once a month. A site “falls short” when the result is anything other than a pass. That is not always a mistake: a very large site may skip something on purpose. Sites that refuse automated visits are not in the sample, so the figure describes the popular sites that could be read, not the whole web. Full method and limits
