Market read
The Greenville HVAC market exhibits a spam problem: 33% of top-3 reviews (internal benchmark, Apr 2026) lack authenticity. Despite this noise, leaders maintain 4.95 average ratings across a median of 85 reviews. The density tier is DENSE, indicating fragmented competition. Top performers generate 10.83 reviews monthly and hold 63/100 Google Business Profile completeness scores. Backlink strength clusters around 75.5 median referring domains for leaders, with one consistently cited by ChatGPT. Pack entry occurs at 4 reviews. Businesses at p25 face a structural gap: reaching top-3 requires scaling review velocity while maintaining rating integrity and securing 70+ domain citations—a multifactor climb, not a single-metric play.
