What is an answer engine?

By the Variask team · Updated

Definition

An answer engine is a search tool that replies with a direct, written answer instead of a list of links. ChatGPT, Perplexity, Gemini, Claude, Copilot and Google AI Overviews all work as answer engines.

With Variask: Variask tracks how 9 answer engines describe your brand and competitors, in any market.

How answer engines differ from search engines

  • They write one answer, usually naming only a few brands.
  • They mix what the model learned in training with pages found live.
  • They support follow up questions in a conversation.
  • They often show citations, but many readers never click.

What it means for brands

  • With fewer slots in the answer, being named matters more than ranking somewhere on page one.
