What the page actually says
- Engines
- Three named engines. Says plainly that AI search optimisation, GEO, AEO and LLM SEO “describe the same work”, and refuses to sell four services for it.
- Method
- Queries the major assistants with the questions homeowners in the market actually ask, and tracks whether the client is named. Practice described, no prompt count or artefact.
- Change over time
- Nothing published.
- Entity and schema
- LocalBusiness, service, FAQ and review schema named specifically, with entity consistency explained as an inclusion problem rather than a listings chore.
- Falsifiability
- The strongest in the set. An entire section headed what it will not tell you: that SEO is dead, that it can guarantee ChatGPT will name you, or that this is urgent enough to skip fundamentals.
The check we would run on this one
The unusual thing about Plumber SEO is what it declines to promise, which is worth reading in full on its own page. Open plumberseo.net/ai-search-optimization/ and find the passage where it limits its own claims. Then ask the obvious follow-up: given that honesty, what does the reporting actually contain, because a stated limit and a stated method are different things and this page is stronger on the first.
We found nothing on Plumber SEO's page we would challenge, which is rarer in this set than it ought to be.
