Market read

Top-3 plumbing businesses in Spokane maintain a median 437 reviews while operating at 59% Google Business Profile completeness (internal benchmark, Apr 2026)—a gap suggesting review volume outpaces profile optimization. The market ranks as DENSE, with pack-entry competitors holding just 6 reviews. Top performers average 4.82 stars with 6.17 monthly review velocity (internal benchmark, Apr 2026), though 17% spam contamination warrants attention. Backlink authority concentrates heavily; top-3 median referring domains reach 187 with DFS rank 135. AI citation data shows named placement in ChatGPT recommendations for local searches. Competitors at the p25 entry threshold need sustained review generation and profile completion to close the 431-review gap separating them from top-3 positioning.
