Generative search
Generative search is search in which an AI model writes a direct answer to the question, instead of only listing links to web pages.
Classic search returns a SERP: a ranked list of pages and ads, leaving the user to click and read. Generative search uses a large language model to read sources and compose an answer in plain sentences, often with follow-up questions in a chat. Google's AI Overviews and AI Mode are examples inside a traditional search engine. Standalone AI assistants are another.
Search arbitrage was built on the classic pattern. Its whole revenue is the click from a list of sponsored listings, and its related-search units mimic the act of refining a query. Generative search changes the pattern in three ways. People may get the answer without clicking (zero-click search). Queries become longer and more conversational, which changes which keywords have ads. And the places where ads appear are being redesigned (Ads in AI assistants).
How far this goes is uncertain, and honest forecasts differ. Commercial queries, where someone wants to compare, buy or hire, still need a destination, and that is where most arbitrage revenue sits. But a business whose supply and demand both come from search platforms has to watch this shift closely: it is a clear case of platform risk.
Think of it like this
Classic search is a directory that lists every plumber in town. Generative search is a neighbour who simply says "call this one".
