What is generative engine optimization (GEO)?

Key takeaways

• GEO means making your brand show up, and show up accurately, in AI-generated answers.
• AI engines retrieve sources, then write one answer that names a few brands. Being named matters more than being linked.
• GEO builds on SEO: crawlable pages, quotable content and authority across the web.
• Measure it by testing real buyer questions in several engines, several times each.

What GEO means

Generative engine optimization is the practice of improving how often, and how accurately, AI engines mention your brand when people ask them questions. The engines include ChatGPT, Perplexity, Gemini, Microsoft Copilot, and Google's AI Overviews and AI Mode.

Where SEO aims for a high position in a list of links, GEO aims for a place inside the answer itself. That answer often names only a handful of brands, so the gap between being mentioned and being left out is large.

How AI engines choose their sources

Most AI search features work in two steps. First they retrieve pages that look relevant to the question, much like a search engine does. Then a language model reads those pages and writes a single answer, sometimes with links to the sources it used.

So two things decide whether you appear: whether your pages are retrieved at all, and whether what they say is clear and trustworthy enough to use. Pages on other sites matter too. In Pew Research Center's analysis of Google searches from March 2025, Wikipedia, YouTube and Reddit were the most cited sources in AI summaries.¹

GEO vs SEO

The two overlap heavily. Pages AI engines can't crawl or read won't be cited, and authority earned through links and mentions helps in both. The difference is the finish line.

What affects your visibility

Five things decide most of it. None of them are tricks; all of them also help in ordinary search.

1. Crawl access. AI crawlers need to reach and read your pages. Check your robots.txt, and make sure important text doesn't depend on scripts.²
2. Clear brand facts. The same name, description, prices and locations across your site and your profiles elsewhere.
3. Quotable content. Direct answers, specific numbers and named sources, near the top of the page.
4. Third-party mentions. Reviews, media coverage, communities and comparison lists that talk about you.
5. Structured data. Schema that describes your organisation, products and articles.

How to measure it

Choose the questions your buyers actually ask, at every stage of buying. Run each one in several engines, several times, because answers change between runs. For each, record whether you are mentioned, cited with a link or recommended, how you are described, and which competitors appear instead.

Where to start

1. Check that AI crawlers can access your site.
2. Fix wrong facts about your brand on your own site and main profiles.
3. Write direct, sourced answers to your top buyer questions.
4. Earn mentions on the sites AI engines already trust in your market.
5. Track the same questions every month.

FAQ

Is GEO the same as AEO?

Mostly. Answer engine optimization (AEO) and GEO are often used for the same work: optimising for AI-generated answers rather than lists of links.

Does GEO replace SEO?

No. GEO builds on SEO's foundations and adds a new goal: being mentioned in the answer, not only ranked beneath it.

How long does GEO take?

Fixing crawler access and wrong facts can show results quickly. Earning regular mentions usually takes months of content and authority work.
