AEO vs GEO: two names, one job?

What each term covers, where they overlap, how both relate to SEO, and how to measure the work whatever you call it.

Updated 30 Oct 20264 min read4 sources

The short answer

AEO vs GEOAEO is about being the answer on any answer surface, from featured snippets and voice to AI chat. GEO is about being named and cited by generative AI engines. For ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews, the work is largely the same.

GEO has a clear origin: a 2023 research paper that coined “generative engine optimization”, later published at KDD 2024.1 AEO grew out of the earlier push to win featured snippets and voice answers, and now also covers AI answers. Usage varies between authors, so expect overlap.

Where they agree

Whatever the label, the useful work is the same list:

  1. Readable pages

    Pages that can be crawled and indexed. Google's AI features draw on its normal Search index.2

  2. Answer first

    Lead with a plain answer to the question, then the detail.

  3. Specific, sourced facts

    Google asks whether content offers original information and analysis.4 The GEO paper found citations, quotations and statistics helped in generative answers.1

  4. Presence beyond your site

    Fair mentions on the review sites, communities and comparisons that answers cite.

Where they differ

SnippetsA featured snippet lifts one passage from one page, and Google says you can't mark a page to be chosen.3 Classic AEO optimizes that passage.
SynthesisGenerative answers combine several sources; Google describes a query fan-out across subtopics.2 GEO cares about being one of the names in that synthesis.
Brand framingIn a generative answer, the reason given for your brand is part of the result. GEO pays attention to that wording.
MeasurementSnippets can be checked on a results page. Generative answers change between runs, so GEO needs repeated checks across engines.

In practice: if you sell to people who ask ChatGPT or Google's AI before they buy, call it what you like, but track the answers.
