Generative Search
A search experience that generates an answer in natural language — using retrieved sources as input to an LLM — instead of returning a list of links.
In plain English
Generative search is the broader category that includes AI search and AI Overview: any search product where the output is an AI-generated answer rather than a list of links. The mechanism is almost always retrieval-augmented generation — pull relevant sources, then ask an LLM to write the answer.
Names you'll see:
- SGE — Search Generative Experience (Google's earlier name for AI Overview)
- AI Overview — Google's current branded name
- AI Mode — Google's expanded standalone version
- Answer engines — what Perplexity calls itself
Why it matters for publishers: Generative search collapses the funnel: users get the answer in the search results, fewer click through to source sites. Sites whose content trains and feeds these systems may see fewer visits even when their content is the answer. This is the largest open question for SEO in 2026.
Citation behaviour: Generative search products cite differently — Google AI Overview shows source cards, Perplexity puts inline footnotes, ChatGPT Search shows a citations panel. Earning citations is the new ranking game.
