The source records 35-50% of Google Business Profile interactions ending in a phone call or direction request. The phrase appears to combine selected profile interaction types, but the denominator, reporting window, business mix, and collection method are not documented.
General local SEO surveys are mentioned without a supporting URL, so the range should remain classified as previously published and unresolved rather than verified. Operationally, a deck builder can still use the metric to check whether profile information, service details, photos, and contact paths are accurate and useful.
It does not prove that a posting cadence, photo routine, map embed, review response pattern, or other undocumented activity causes local rankings. The source's earlier recommendation to respond to 100% of reviews is better treated as a customer-service practice; respond professionally when a response is appropriate and measure profile interactions against qualified inquiry records with consistent definitions.
The source also reports 15-25% higher CTR for listings with at least 50 five-star reviews in 2026. This appears to compare click-through behavior across listings grouped by review profile, but the source gives no study URL, query set, control variables, business mix, or attribution method.
It is therefore an observational comparison, not evidence that reaching a particular review count or rating causes higher CTR or stronger rankings. A safer decision use is to treat reviews as information prospective homeowners may consider: ask eligible customers consistently for honest feedback, without incentives, review gating, discouraging negative feedback, or selecting only satisfied customers, and evaluate whether review content helps people understand the contractor's actual project experience.
