What to do with it
-
1
Complete every directory listing the AIs quote in your market: details, hours, photos, recent reviews. It is the biggest lever.
-
2
Get into the guides and "best of" lists of your city and trade.
-
3
Keep your own site clear and complete: it is quoted in 38% of answers, and that is where an AI checks what you do.
Method
Every answer comes from the AIs' official APIs with web search on, as they answer their own users, for the businesses tracked in kwerve and audits we ran. Each quoted site is sorted by type, by rules and a one-time AI label. A measurement of what the AIs answered, not a random sample of all businesses.
Numbers as of 12.10.2026: 295 answers, 2,280 quoted sites.
