Hot take: most llms.txt files are vanity. Here's how to build one that earns its keep.

Don't dump your sitemap. Curate:
— List ONLY your 15-20 highest-authority, most-citable pages
— One line per URL: what it definitively answers, in plain words
— Add a top block stating who you are as an entity and what you're the authority on
— Link your original data and definitions first, blog fluff never
— Update it when your best content changes, not never
A bloated llms.txt is noise. A curated one is a pitch. Tell the model what to trust, or it guesses. Fight me.
