AI Visibility

GEO vs SEO: what’s the difference — and do you need both?

The Orchestra Team · August 26, 2026 · 5 min read

For more than two decades, the objective of SEO has been relatively clear: get discovered by search engines and earn visibility for relevant searches. That hasn't disappeared. What has changed is the interface between the search engine and the user.

Instead of query → list of links → website, we increasingly also see question → generated answer → sources and recommendations → optional website visit.

That is where Generative Engine Optimization (GEO) enters the picture.

What is SEO?

Search Engine Optimization improves a website's ability to be crawled, indexed, understood and surfaced by search engines. It covers technical SEO, content, internal linking, site architecture, authority, structured data, user experience and local SEO.

These fundamentals remain essential. Google states that SEO best practices remain relevant for AI features in Search, because those features still depend on its principal ranking and quality systems.

What is GEO?

GEO focuses specifically on visibility inside generative search experiences. Instead of only asking where does my webpage rank?, GEO asks is my business or content being used when AI generates an answer?

That introduces different measurements:

| | Traditional SEO | GEO | |---|---|---| | Example metric | Position #4 | Your company appears in 7 of 20 relevant AI discovery prompts | | Example metric | 3,000 organic impressions | Your domain was cited in 18 AI-generated answers |

Where SEO and GEO overlap

The overlap is substantial. Good SEO improves:

  • Crawlability — search systems need access to your content.
  • Understanding — pages need clear subjects, relationships and structure.
  • Authority — useful, credible information has a better foundation for discovery.
  • Content quality — AI systems don't produce useful grounded answers without useful underlying information.
  • Freshness — current information is more useful than obsolete information.

This is why businesses should be cautious about anyone selling GEO as a collection of secret technical hacks. Google explicitly says special AI markup, special schema.org markup and llms.txt are not required for visibility in its generative AI features — and that creating such files "will neither harm nor help your site's visibility or rankings in Google Search."

Where GEO adds something new

The meaningful difference is measurement and intent.

Traditional SEO tends to evaluate rankings, impressions, clicks, CTR, organic sessions and conversions. GEO adds brand mention rate, citation rate, AI prompt coverage, competitor visibility, thematic visibility and AI referral traffic.

Microsoft's AI Performance reporting already reflects this shift, exposing citations, cited pages and grounding queries rather than a traditional SERP position.

An example

Imagine you run an accounting firm in Manchester. You rank well for accountants Manchester. That's SEO visibility.

But a prospect asks an AI assistant: "which accounting firms in Manchester specialize in technology startups?" Three competitors are recommended. Your firm isn't.

That's an AI visibility gap. The cause could be insufficient content around startups, unclear service positioning, weak evidence, poor entity consistency, competitors with stronger topical authority, or insufficient third-party signals.

You wouldn't see that problem by checking your ranking for accountants Manchester. Why AI recommends your competitors works through the likely causes.

So which one should you invest in?

Both — but not as separate universes. A sensible framework:

SEO builds the foundation. GEO measures and improves the new discovery layer on top of it.

Businesses shouldn't abandon Google rankings to chase ChatGPT mentions. They should build strong websites, strong content and strong authority, while expanding measurement to include how AI systems interpret and surface the brand.

How Orchestra connects SEO and GEO

Orchestra treats GEO as part of the wider marketing system rather than an isolated technical discipline. A GEO audit identifies where the brand appears, where it doesn't, who appears instead, which topics need attention, and what actions should come next. Those actions then inform content and broader marketing execution.

That creates a feedback loop: measure → identify gap → create → publish → measure again.

SEO answers "can people find us through search?" GEO adds "does AI include us in the answer?" Modern businesses increasingly need to know both.
