The pattern holds here as it does across every trade in the study: an AI engine can nearly always reach these sites. What it cannot do is describe them precisely, because the machine-readable facts and the answer-shaped content it needs are missing.

The most common single failure in this trade is FAQPage schema, missing on 93.9% of plumbing sites audited. It is worth knowing that this is a fixable, mechanical problem rather than a content one: it is a block of markup stating who the business is and what it answers, not a rewrite.

The spread between trades is much smaller than the spread inside any one of them. Who built the website matters more than what the business does, which is why a trade average is a starting point and not a verdict on any one site.

04Method, in short

Businesses were drawn at random from Overture Maps open place data across 50 US metros, one per registrable domain, with a fixed seed and no score filter. Every business drawn was audited and counted. 49 plumbing businesses responded and were scored against the same 23 checks we run for clients. Full method, limitations and the null results we could not explain away are on the main Index page, and every figure is published as JSON under CC BY 4.0.
