"Is this a real, established business with enough history to name?"
Threshold signal
Works like a floor, not a scoreboard. 9 reviews vs 300 matters. 400 vs 600 mostly doesn't. Compare yourself to the companies AI already names in your city.
"Is this business credible, and does the profile look organic?"
Band signal
Below ~4.0 hurts. 4.3 to 4.8 is the credible band. A 5.0 on 22 reviews reads as a campaign, not a business. Chasing 4.6 → 4.9 is wasted effort.
"Is this business still operating and still doing the work well?"
Freshness signal
The one most businesses lose quietly. A few new reviews every month beats 60 in one quarter, then silence. A 14-month-old newest review answers nothing.
"What exactly does this business do, and where does it do it?"
Highest leverage
Models read the sentences, not just the score. "Same-day water heater swap in Collierville" earns a specific recommendation. "Great service!" earns none.
