A synthetic answer is the response an AI system generates by gathering information from multiple sources and synthesizing it into a single reply. It is the output of AI search — the answer that now sits where a list of links used to be.
The word synthetic is literal: the answer is synthesized, assembled. It is not retrieved whole from any one page. The AI system reads several sources and composes a new response from them.
The short definition
A synthetic answer is an AI-composed reply built from multiple sources, presented in place of a list of links.

Surface
What the user sees
How visibility works
Classic search result
A ranked list of 10 blue links
Compete for rank position; every result has a click chance
Synthetic answer
One composed paragraph naming a few brands inside the prose
Compete to be one of the sources the answer is built from — there is no tenth place

Why it changes the stakes
A list of links gave every result a chance — ten brands visible, the user free to choose. A synthetic answer names a few brands inside the prose, or sometimes none. There is no tenth place in a synthetic answer. A brand is either part of the composition or absent from it.
This is why citation matters more than ranking inside AI systems. The synthetic answer is built from the sources the system trusted enough to use. To shape the answer, a brand has to be one of those sources — which is the work of Generative Engine Optimization (GEO).

What a brand should ask of it
The practical test is simple: put the questions that matter in the category to the major AI systems, and read the synthetic answers they return. Is the brand named? Is what the answer says about it accurate? Those answers are the brand's first impression for a growing share of buyers — and they are visible to anyone willing to look.

A synthetic answer is the new shape of a search result: composed, not listed, and far more selective. It is built from the sources an AI system trusts. For a brand, the goal is no longer to rank near the answer — it is to be part of it.
