What is Generative Engine Optimization (GEO)?

At a glance

• GEO targets citation inside a generated answer, not a ranking position on a results page.
• The competitive set is narrower: an assistant names a few sources where a results page lists ten.
• Assistants read pages in chunks, so one strong section can be cited while the rest is ignored.
• GEO and SEO share a technical base. A page an AI crawler cannot read cannot be cited.
• Progress shows up as citation rate and share of model, not keyword position.

How an assistant decides what to cite

When someone asks ChatGPT or Perplexity a question, the assistant does not run one search. It breaks the question into smaller searches, pulls passages from a range of sources, and writes one answer from what it retrieved.

Two things follow.

Your page is not competing once. It competes in every sub-search the generative engine runs, so coverage across a topic beats depth on one phrase.

And the unit being judged is the passage, not the page. A clean, self-contained paragraph answering one question gets pulled into an answer while everything around it is skipped. The 2023 paper that named the practice, GEO: Generative Engine Optimization, tested that shift: what changes when the thing scored is a fragment, not a document.

Why one answer changes the maths

In search, position ten still gets clicks. In an AI answer, the sixth-best source gets nothing.

That sounds bleak. In practice it cuts the other way for most brands. The sources an assistant reaches for are not the ones with the biggest backlink profile. They stated something clearly, recently, in a form that could be lifted without editing. A mid-sized brand with sharp pages regularly beats a larger competitor whose content is buried in a PDF.

The other shift is that the traffic mostly does not arrive as traffic. A shopper reads your name in an answer and turns up later as a branded search, which your analytics will not connect to the answer that caused it. Measuring GEO by sessions will tell you it is not working while it is working.

How to start competing for citations

Nothing here requires a platform. Start with the fixes anyone can make this month.

1. Put a real answer in the first 60 words of every page. Full sentence, term as the subject, no lead-in. A block that reads correctly on its own can be quoted on its own.
2. Break long sections into self-contained chunks. One idea per section, no back-references. Assume each paragraph is read alone.
3. Check that AI crawlers can read you. Server-rendered HTML, nothing locked behind JavaScript, GPTBot and ClaudeBot allowed in robots.txt. Google’s documentation on AI features and your website covers the controls on its side. Most failures we see are here, not in the content.
4. Publish something only you know. Your own numbers, tests and customer data. Definitions are commodity; original data is the reason to name you.
5. Track prompts, not keywords. Write down 30 questions a real buyer would ask about your category and check monthly whether you appear. That list beats any rank tracker.

GEO vs SEO

The two are not rivals. Almost everything that makes a page work for GEO also works in search, and broken crawlability fails at both. GEO vs SEO walks through the overlap.
