Three evidence categories are described: keyword research tools, internal pool service campaign observations, and published home-services research. Those inputs should not be treated as interchangeable because each measures a different thing and the underlying datasets are not embedded here.
Where internal experience is referenced, treat the statement as an observation rather than an industry-wide benchmark. Where third-party organizations are named, those attributions require validation before being presented as independently verified evidence.
Market limitation: an example with 200 local operators versus 15 competitors illustrates how competitive density can change the context. Those values are examples, not documented market counts for a named location and not a causal model of ranking difficulty.
The stated edition reflects conditions observed through early 2026. Figures older than 18 months should receive additional skepticism. That is a useful freshness rule for planning, but every material benchmark should still be checked against current platform data, local search results, and first-party performance before it is used operationally.
