Market read
Plumbing's top-3 median reviews (85 reviews, internal benchmark, Apr 2026) sit just one review ahead of pack-entry floor at 84, signaling tight competition in a DENSE market. Average rating holds steady at 4.91, though Google Business Profile completeness lags at 68/100 across leaders. Review velocity averages 8 per month with an 8% spam rate. Backlink authority remains strong—top-3 median referring domains reach 397 with median DFS rank 230. Notably, ChatGPT cites zero of Google's top-3 when queried for local recommendations, indicating offline reputation hasn't yet translated to AI visibility. For p25 entrants targeting top-3 status, the gap is modest in raw review count but substantial in profile optimization and emerging AI-search positioning.
