My site looks fine. Why is it cold?

Because looking fine is a statement about a browser and this is a statement about a fetch. The two diverge more than people expect.

The three that catch working, attractive, professionally built sites most often: content assembled client-side so the response is nearly empty, a robots.txt blocking AI crawlers that nobody has revisited since 2023, and no structured data at all, so every fact on the page has to be inferred from prose.

None of those are visible to a human. All three are worth more than 10 points each.
