What is GEO? Generative engine optimization, explained

Updated 17 October 2026By GrowMarketingPro3 min read

Quick answer

GEO, or generative engine optimization, is the practice of improving how often and how favourably generative AI systems, such as ChatGPT, Gemini and Claude, mention your brand and cite your content when they write answers. It focuses on the sources these systems rely on and on how your brand is described across the web.

What changes

Why GEO is different from SEO

A search engine shows a list of links. A generative engine reads several sources and writes one answer that names only a few brands.

Being named beats ranking

If you're not in the answer, there's no second page to fall back on.

Order matters

The brand named first is usually the one the answer recommends.

Description matters

The words the AI uses about you shape the buyer's first impression.

Other people's content matters

The answer is built from many sources, not just your website.

Measure it

The GEO metrics that matter

Mention rateHow often you are named in answers to the questions you track.

PositionWhere you appear in the answer when you are named.

Share of voiceYour share of all brand mentions compared with competitors.

FAQ

Frequently asked questions

Is GEO the same as AI SEO?

Broadly, yes. AI SEO is the umbrella term for optimising for AI search. GEO is the more specific name for optimising for generative engines that write answers. See also the free AI SEO checker.

Which AI engines matter for GEO?

Start with the assistants your buyers use most. For most markets that means ChatGPT, Gemini and Claude, which GrowMarketingPro tracks.

Can I do GEO without paid tools?

You can ask AI assistants your questions by hand, but answers vary and are hard to compare over time. The free plan automates this for one brand and 10 questions, checked weekly.

How quickly does GEO show results?

Improvements to your own pages can show up within weeks once they are crawled. Gaining mentions on third-party sources usually takes longer. Track the same questions over time to see the trend.
