Plumbing in San Francisco, CA: top 60 ranked
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
- 3 of the 47 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: George Salet Plumbing, Inc. (GPTBot, ClaudeBot), ASAP Plumbing Pros (GPTBot, ClaudeBot), Rapidfix Plumber San Francisco (GPTBot, ClaudeBot).
- 16 of the 47 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.
- 9 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.

9 of these 60 rows share a score with another row and are marked Tied on score. Rows are ordered by score, and rows on an equal score are left in the order the Google Places query returned them in, so the difference between two tied ranks is not something this rubric measured.
These rows as data: data.json and data.csv. Both are written beside this page in the same build, from the same scan record the table is built from.

The count is how deep that scan was run, not how many businesses the market held that day. A scan run deeper finds more because it looked further, and scans are never compared across rubric versions.
