Public Registry

Every AAIR™-verified business, verifiable.

This is the public proof layer of the AAIR™ standard. Every AAIR seal — on a truck, a website, a Google profile — links to an entry here. If a seal doesn't resolve to a live entry, it isn't real. Issued by the AI Visibility Institute; scored across the leading AI answer engines.

AI Visibility Rankings — by trade and metro

The same reproducible AAIR standard, published as category rankings. This is the currency analog to the seal: a J.D. Power-style ranking or a Nielsen rating for AI answers — who the engines actually name, trade by trade and metro by metro. Independent of any engagement; the measure stands on its own, or it's worthless.

Published in full — winners and non-appearances alike. Only ChatGPT and Perplexity name any local sign shop for these grounded queries; Gemini, Claude, Google AI Overview and Grok name no local shop yet, and appear as columns the moment they do. Run the queries yourself and you’ll get the same names. Brand 9 Signs is a PRAGMA client, measured on the identical method as every other business here.

Measurement note (2026-08-06): an earlier census over-credited several shops before the grounded ruler was tightened; this dated entry is the corrected, reproducible reading. Grounded “who’s best” naming is volatile run-to-run, so we publish each dated census rather than the most flattering one.

Scored across ChatGPT, Gemini, Perplexity, Google AI Overview and more — the AAIR standard v1.2, public and reproducible.

2 · Issued

A passing score earns a tiered, signed credential from the AI Visibility Institute, with an "as of" date and a quarterly re-measure.

3 · Verifiable
