Generative Search
In one line
Generative search is the search paradigm where results are delivered as an LLM-written answer rather than a list of links — think AI Overviews, ChatGPT Search, Perplexity.
Going deeper
Generative search is the model where the engine writes the answer for you instead of returning a ranked list of links. AI Overviews, ChatGPT Search and Perplexity are the canonical examples — the engine is no longer sorting candidate links, it is composing a reply.
Two shifts matter for marketers. First, more users finish the journey without clicking through. Second, exposure narrows to the small set of sources the engine chose to cite. The game moves from 'rank in the top ten' to 'be one of the cited two or three'.
The space is still unsettled. Different surfaces use different citation styles, and the same prompt can swing across runs. The pragmatic move is to track how your brand shows up across multiple surfaces rather than chase a single global score.
