Claude writes comparison tables and names 14.7 businesses per query. ChatGPT writes numbered lists and names 9.1. Perplexity cites sources and names 8.4. Same question, three completely different answers — and the AI engine your buyers use determines the format, the directories cited, and even whether specific providers get named at all.
