ChatGPT, Claude, Gemini, Perplexity, and the rest each pull from different sources, serve different people, and answer different kinds of questions well. If you want to show up when customers ask an AI for a recommendation, it helps to know which assistant does what.
Why Platform Differences Matter
Optimize for only one assistant and you miss everyone who uses the others. Each one draws from its own mix of data, serves a somewhat different audience, and is strongest at a particular kind of query. The good news is that the foundational work (an accurate, consistent web presence and real reviews) helps you everywhere at once. From there, a few platform-specific moves round things out.
