Does llms.txt Get You Cited by AI? I Checked the Data.
The SEO argument about llms.txt has moved on from adoption to effect: does shipping one actually get you cited by ChatGPT and Perplexity? I have my own AI-citation tracker, so I probed every domain those engines cited us alongside. The correlation is real and large, about 10x. The causation claim falls apart the moment you look at which domains get cited most.
