AI search
AI search is any search experience where a language model reads the web and returns a synthesized, cited answer — ChatGPT search, Perplexity, Google AI Mode, Gemini — instead of a ranked list of links.
Also searched as: AI search engine, ChatGPT search, Perplexity.
AI search changes the unit of success from a ranking position to a citation inside an answer. A page can rank #3 organically and still be invisible in AI search if the model never quotes it; conversely, a well-structured page can be cited even when it ranks modestly.
Important constraint for marketers and their agents: most AI crawlers do not execute JavaScript, so any content that only appears after client-side rendering is invisible to them. Important text must be server-rendered.
