Before using these figures for an electrical contractor budget decision, separate what the source actually documents from what it merely states. The supplied JSON names public research publishers, keyword tools, and campaign observations, but it does not include source URLs that would let a reader independently verify most of the cited benchmark claims.
That matters because a statistic without a visible study edition, sample, collection method, geography, or metric definition should not be presented as universally verified. The source also contrasts a 20-person electrical firm with a smaller operator to illustrate how market structure can differ, but that example does not establish a benchmark by itself.
Edition and period also matter. The source warns that older data from 2023 may not represent behavior in 2026, especially where search result layouts and Google AI features have changed. Treat time-sensitive claims as historical unless the exact study edition and field period can be reconciled.
For decision use, attach five questions to every benchmark: what was measured, who or what was sampled, when the data was collected, how the metric was defined, and whether the result is descriptive or causal. If those details are unavailable, use the figure only as a planning reference and validate it against first-party analytics.
Market size, residential versus commercial demand, service urgency, local competition, website maturity, and attribution quality can all change the observed result. A useful benchmark is a comparison point, not a guarantee, target, or substitute for the contractor's own data.
