Scored on reputation, findability, content, trust and AI visibility. Last updated 2026-09-09, rubric 3.0.0. This is the top 60 listings Google Places returned for this trade and city, not a complete census of the market. How this is scored.

What the data shows

4 of the 50 sites this scan could read disallow an AI crawler in the robots.txt of the site their Google listing points to, which asks that vendor not to fetch the page: Affordable Drain Flow Inc. (GPTBot, ClaudeBot), Green Tech Plumbing & Heating (GPTBot, ClaudeBot), Gomes Plumbing Heating & Cooling (GPTBot), A.F. Ventolieri Plumbing & Heating LLC (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot).
25 of the 50 sites this scan could read publish no LocalBusiness structured data, so nothing in their markup states the business type or the city it serves in a form a machine can read.
6 of 60 have no website on their Google listing.
4 of 60 list a website this scan could not audit: it redirected away from the listed address, answered with an error, or did not answer at all.
