Market read
Duluth's plumbing market shows minimal AI visibility despite moderate review activity. The top-3 median sits at 63 reviews (internal benchmark, Apr 2026) with a 4.69 average rating, yet ChatGPT named zero of these leaders when queried for local recommendations. Review velocity averages 2 per month across top performers, while median GBP profile completeness languishes at 41/100—a gap competitors rarely exploit. The p25 entry floor stands at just 3 reviews (internal benchmark, Apr 2026), indicating a SPARSE density tier where modest review counts still position businesses competitively. Top-3 backlink profiles average 80.5 referring domains with a median DFS rank of 130.5. A p25 business targeting top-3 status should prioritize GBP optimization and sustained review velocity, as the field remains underdeveloped relative to review counts alone.
