What is GEO?
GEO (generative engine optimization, or optimizing for generated answers) is the work of getting a business to appear in the answers written by generative systems: ChatGPT, Gemini, Claude, Perplexity, Copilot and Google's AI Overviews. Google writes that, from its point of view, this work is SEO. What changes is the surfaces targeted and the way results are measured.
What GEO is for
A buyer who asks an assistant a question gets a written answer rather than a list of links. GEO aims to have your business named in it as a source, or recommended, when the question is about what you offer.
The expected result is not primarily a visit. A citation produces few clicks: the Pew Research Center measured a click on a source cited in a Google summary in 1% of visits. Its value is presence at the moment the customer is searching.
What Google says about it
On May 15, 2026, Google published its documentation on optimizing for its generative features. It acknowledges the GEO and AEO acronyms. It writes that this work is SEO, because its summaries rest on its usual ranking and quality systems. A page that is neither indexed nor ranking well therefore has little chance of being picked up.
The same documentation rules out several practices sold as AI-specific: the llms.txt file, pre-splitting content into chunks, and Markdown versions of pages.
What really differs from SEO
Two gaps remain. The first is the surface: ChatGPT, Claude, Perplexity and the other assistants fall outside Google's documentation. The second is measurement. Search Console reports impressions in AI Overviews and AI Mode, without clicks. Outside Google, presence is tracked against a list of questions set in advance: that tracking shows a trend, never a volume.
Fictional example: a landscaping company lists twenty questions its salespeople hear before a sale ("which contractor should I hire for a retaining wall?"). Every month, it asks those questions to ChatGPT, Perplexity and Gemini, then notes who is cited. It shows up in 3 answers out of 20 in January, then in 7 in June: its presence is growing. This tracking does not say how many sales those citations produced.
At Falia, SEO and GEO are a single discipline: organic search is the foundation and optimizing for generative engines is its extension. GEO is part of every SEO engagement, at no extra cost. The SEO audit always includes the GEO audit. The only spending that honestly separates from SEO is tracking the surfaces outside Google.
We read a citation as presence, not as a traffic source. No one today can honestly tie a citation to a closed sale. What gets a business cited is still content its competitors cannot publish: its numbers, its real timelines, its documented cases.
Not to be confused with
- AEO
- AEO aims to make a page the direct answer shown for a question (featured snippet, answer box, voice search). GEO aims at being cited as a source in an answer written by a generative system.
- SEO
- SEO aims at ranking in the list of results. GEO is its extension: it rests on the same foundations, but it targets a written answer rather than a position.
- Local SEO
- Some agencies use "GEO" for local SEO (the business profile, near-me searches). On Falia's site, GEO always means generative engines.

Frequently asked questions
Can you measure GEO results?
Partly. Google reports impressions in its AI Overviews, without clicks. Bing publishes Copilot citations. Elsewhere, presence is tracked by hand against a fixed list of questions.
