GEO vs SEO: ranking in results vs winning the answer

SEO competes for the click. GEO competes for the answer. Here is what changes when your buyers ask AI instead of searching, and how to tell which problem you have.

The short answer

Same buyer, different shelf

Search engine optimization (SEO) gets your pages ranked so a buyer clicks through to your site. Generative Engine Optimization (GEO) gets your brand named, cited and, ideally, recommended first inside the answer that ChatGPT, Claude, Gemini or Perplexity writes.

You still need SEO. AI assistants read the same web, and often the same search indexes, that SEO has spent years making crawlable and credible. What changes is where the decision happens. More and more of the shortlist is built inside the conversation, before anyone visits your site, so your analytics never see the deal you lost.

"Ranking gets you on the list. GEO decides whether AI reads your name out first."

Side by side

SEO and GEO, compared

The disciplines overlap. The questions they answer do not.

	SEO	GEO
What you compete for	A position in a list of links	A place inside the answer, ideally as the first recommendation
Where the buyer decides	On your site, after the click	Often inside the AI conversation, before any click
How the buyer asks	Short keywords	Full questions with context, then follow ups that narrow the shortlist
The unit you optimise	The page	The brand: how models describe, cite and rank you
Who you compete with	Whoever ranks on page one	Whoever the model names alongside you, including review sites and directories
Main signals	Relevance, links, technical health	Mentions across the web, credible sources, clear facts the model can quote
What you measure	Rankings, impressions, clicks	Mention rate, citations, Win of Visible (WoV)
What a win looks like	A visit	Being the brand AI recommends first

The SomRise Win Ladder

Four rungs between being online and being chosen

SEO mostly lives on the first rung. GEO is the climb to the fourth. Diagnose from the bottom up: a brand AI cannot read will never be recommended.

Reachable

AI crawlers can fetch and read your key pages. Content that only appears after JavaScript runs may be missed.

Recognised

Models know who you are, what you sell and who you sell to, and describe you correctly.

Referenced

Your pages and third party mentions of you are among the sources AI cites.

Recommended first

You are the top pick once you appear. This is what Win of Visible (WoV) measures.

Measurement

Rank tells you where your page sits. WoV tells you whether AI picks you.

SEO has mature measures: rankings, impressions, clicks. GEO needs its own. SomRise tracks three:

Mention rate: the share of relevant AI answers that name your brand at all.
Citations: which sources the models link to when they talk about your category, and whether your own site is one of them.
Win of Visible (WoV): wins as #1 recommendation ÷ conversations where your brand is visible. Once AI knows you, does it choose you?

The average enterprise brand scores 38% on the SomRise AI Visibility framework across 11 AI model families. Most do not know there is a gap until it is measured. How Win of Visible works →

What to do first

Four moves that serve both SEO and GEO

Earn mentions, not only links. In an Ahrefs study of 75,000 brands, branded web mentions correlated with AI Overview visibility at 0.664, against 0.218 for backlinks. Being talked about on other credible sites matters. Ahrefs, 2025 ↗
Write pages AI can quote. Researchers behind the original GEO paper found that adding statistics, quotations and cited sources could lift visibility in generative answers by up to 40% in their tests. Aggarwal et al., GEO ↗
Be indexed beyond Google. AI assistants do not all search the same index. Submit your sitemap to Bing Webmaster Tools as well as Google Search Console, and keep AI crawlers allowed in robots.txt. You can also publish an llms.txt file, a plain text summary of who you are for AI assistants. It is an emerging convention rather than a confirmed ranking signal, so treat it as a low cost extra. See how we structure ours.
Measure the answer, not just the rank. Run the questions your buyers actually ask across the major AI models. Track how often you appear, what is cited, and how often you are recommended first.

FAQ

GEO and SEO questions

What is the difference between GEO and SEO?

SEO works to rank your pages in search results so people click through to your site. Generative Engine Optimization (GEO) works to get your brand included, cited and recommended inside the answers AI assistants such as ChatGPT, Claude, Gemini and Perplexity write. SEO competes for the click. GEO competes for the answer.

Does GEO replace SEO?

No. AI assistants draw on search indexes and on the same pages SEO already makes crawlable and credible. Strong SEO is the foundation GEO builds on. What changes is what you measure and where your brand needs to appear.

How do you measure GEO?

Start with mention rate, the share of relevant AI answers that name your brand at all. Then track citations, the sources AI links to, and Win of Visible (WoV), the share of answers where your brand appears and is recommended first. Rankings and clicks remain the SEO measures.

Is GEO the same as AEO?

The terms overlap. Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) are both used for work that earns a place inside AI written answers rather than a position in a list of links. SomRise uses AI Visibility as the umbrella term.
