Generative Engine Optimization for the AI search era

How brands get mentioned and cited in ChatGPT, Gemini, Perplexity, Copilot and Google AI Overviews — and how to measure it.

Short answer

What is GEO?

Generative Engine Optimization (GEO) is the practice of increasing how often, and how accurately, AI assistants such as ChatGPT, Gemini, Perplexity, Copilot and Google AI Overviews mention and cite your brand. It combines crawlable, fact-dense content, a consistent brand entity across the web, and third-party sources that AI systems already trust.

Key concepts

The GEO concepts worth knowing first

Understand these and most GEO advice — and most vendor pitches — becomes much easier to evaluate.

1

Retrieval & grounding

Most AI search answers are grounded in live web results, so a page must be crawlable and indexed by the engine’s search partner (e.g. Google or Bing).

2

Citations vs mentions

A citation links to your page as a source; a mention names your brand in the answer. Both matter and are measured separately.

3

Citable content

Specific facts, original data, clear definitions and named authors are easier for a model to quote than generic marketing copy.

4

Brand entity

Consistent descriptions on your site, Google Business Profile, LinkedIn, Wikidata and directories help models describe you correctly.

5

Third-party corroboration

Reviews, comparison articles, forums and industry publications are frequently used as sources when assistants recommend vendors.

6

Prompt-level measurement

Track a fixed set of buyer prompts across assistants over time — answers vary, so trends matter more than single runs.

FAQ

GEO questions, answered

No. AI answers are probabilistic and change with the prompt, the model version and live search results. GEO improves the likelihood and accuracy of mentions; anyone promising a guaranteed placement is overstating what is possible.

It can stop specific bots from training on or retrieving your pages, but it also removes you from the answers those assistants give. Decide bot by bot — for example, allowing search-retrieval bots while blocking training-only bots.
