GEO — generative engine optimization — is optimizing for AI-powered search: making sure that when someone asks ChatGPT, Perplexity, Gemini or Google's AI Overviews a question in your space, your business appears in the answer and is cited as a source rather than a competitor.
How generative engines actually work
Most AI answer engines don't invent facts from nothing. They run a retrieval step first, pulling in a handful of pages that already look authoritative on the topic — usually the same pages already ranking well in ordinary search — and then generate a response grounded in those sources, citing the ones it leans on most. That single fact is why GEO can never be separated from SEO: a page that never gets retrieved can never get cited.
What actually moves the needle
- A healthy SEO foundation. Technical health and existing authority decide whether you enter the retrieval set at all.
- Clear, quotable writing. Direct statements a model can lift without distortion, rather than claims buried inside marketing copy.
- Topical depth. Covering a subject completely, the way topical authority content does, signals that the site understands the whole subject rather than getting lucky on one page.
- Structured data. The same schema that helps AEO helps AI crawlers parse exactly what a page claims.
GEO is additive, not a replacement
None of this replaces the layers underneath it. A site with strong technical SEO, content built around real questions, and enough depth to be treated as an authority is already most of the way to being retrievable. GEO adds the last part: writing and structuring with an eye to how a language model reads and quotes, and then tracking how the brand actually shows up in answers.
FAQ
How do AI engines decide what to cite?
Most of them run a retrieval step first, pulling in pages that already rank well and look authoritative on the topic, then generate an answer grounded in those sources and cite the ones it draws from most directly. Sites that don't rank well in ordinary search rarely get retrieved in the first place.
Can I do GEO without doing SEO?
Not realistically. GEO sits on top of the same signals SEO already measures — technical health, authority, clarity — because those decide whether an engine's retrieval step finds the page at all. Treat GEO as an additional layer on a healthy foundation, not a replacement for one.
How do I know if AI engines are citing me?
Run your own brand and topic queries through ChatGPT, Perplexity and Google's AI Overviews and see what comes back. Some analytics tools now separate referral traffic from AI engines, which is worth setting up alongside ordinary Search Console monitoring.
