The domains AI cites when it recommends a business

AI answers aren't magic — they're assembled from sources. When a customer asks ChatGPT, Perplexity or Google's AI for a business, it pulls from directories, review sites, associations and community threads, and names whoever those sources talk about. This is the map of exactly where that happens, by category — so you know where to get listed to get named.
