Schema markup did not change a single naming rate

This one needs a caveat before the finding, because schema is not snake oil. Structured data does real work: it supports rich results, it helps a search engine resolve which entity a page is about, and it is cheap and durable. Keep it.

What it is not is a lever on whether an answer engine names you.

• Complete Organization and Product markup on six B2B SaaS sites that previously had partial or none.
• FAQPage markup on every page carrying a real question and answer.
• Validated with no errors and no warnings before the observation window opened.
• Nothing else shipped on those sites during the window.

Naming rates finished inside baseline variance on all six sites. Entity resolution improved in the places you would expect to see it, which is the thing schema is for 1.

So: deploy it, validate it, and stop reporting it as an AI visibility deliverable. It belongs on the technical hygiene line, next to the things nobody argues about.
