AI Search Optimization

GEO, AEO and GSO, explained plainly: how to make your website readable — and citable — by ChatGPT, Perplexity, Google AI Overviews and Gemini.

When people ask an AI instead of typing a query, ranking on Google is no longer enough — your site has to be readable and quotable by the model itself. That skill splits into three disciplines: GEO, AEO and GSO. Here is what each means, how they differ from classic SEO, and how to check where you stand.

The three disciplines
GEO

Generative Engine Optimization

Making your site likely to be surfaced and cited by generative engines (ChatGPT, Gemini, Perplexity). GEO is about being the source an AI pulls from when it writes an answer.

Improve it with: clean structured data, clear entity definitions, factual and quotable statements, authority signals, and an llms.txt file.

AEO

Answer Engine Optimization

Making your content the direct answer to a question. AEO targets answer engines and AI overviews that return one concise response instead of ten links.

Improve it with: question-based headings, concise answer-first paragraphs, FAQ schema, and well-structured lists and tables.

GSO

Generative Search Optimization

The umbrella term: overall readiness for generative search results, where the search engine itself composes an answer from multiple sources. GSO blends GEO and AEO with technical AI-crawlability.

Improve it with: server-rendered HTML an AI bot can read without JavaScript, fast load times, content freshness, and internal links.

Frequently asked

What is GEO?

GEO (Generative Engine Optimization) is making your site likely to be surfaced and cited by generative AI like ChatGPT, Gemini and Perplexity. It relies on structured data, clear entity definitions, and quotable, factual content.

How is GEO different from SEO?

Classic SEO aims to rank a page in a list of links. GEO aims to be the source an AI quotes when it composes a single answer. SEO optimizes for keywords and backlinks; GEO optimizes for structured data, quotable facts and entity clarity.
