How does the PressGEO Los Angeles AI Visibility Index rank local businesses?

The November 2026 Los Angeles AI Visibility Index is a research report by PressGEO that measures how often 156 local service firms across 14 categories are recommended by AI engines like ChatGPT and Claude. The Index is built from 192 AI answers recorded over a rolling 90-day window and refreshed monthly. A firm's ranking is determined by its share of recorded answers; for example, Elite Group Inspection Professionals and Roof Repair Specialist achieved visibility rates of 44% and 43%, respectively. Rankings are based strictly on recorded AI responses and cannot be purchased.
