Book on Heat

Book on Heat, based in Boise, ID, describes itself simply: "Now, this astonishing science-based breakthrough has turned weight loss research on its head." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 3.2 out of 10.

Under the hood there is a clear heading structure, but the score is capped by what is missing: structured data describing the business, credibility markers like credentials or reviews, the technical files AI engines look for, such as llms.txt or an open robots.txt.

AI crawlers have visited the site once in our tracking, so the engines are already looking. Off the page there is almost nothing to corroborate it: the domain does not yet read as established, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on. That half of the score is earned elsewhere on the web, not on the site itself.
