What is GEO? How AI Visibility is Shaping Brand Reputation

According to a Gartner forecast cited by Meltwater, around 30% of brand perception will have been shaped by generative AI content by 2026: not social media, not press coverage, not reviews – AI.

Predictions like this seemed to be about the distant future – but that future has arrived, and will only increase. For most businesses, it’s a blind spot the size of a billboard.

We’ve been talking about GEO (Generative Engine Optimisation) for a while here at Peaky HQ. We touched on it in our SEO in 2026 piece, as the strategy you can’t ignore any longer. But the more we dig into it, and the more we see how quickly AI is reshaping the way people discover brands, the more we feel it warrants its own conversation. We’re seeing a fundamental shift in how reputation is built.

So, what is GEO?

GEO is the practice of optimising your content and digital presence so that AI platforms (ChatGPT, Perplexity, Google’s AI Overviews, Gemini, Copilot) cite, reference, and recommend your brand when answering user questions.

Traditional SEO was about earning a spot in a list of ten blue links – GEO is about earning a place among the handful of sources an AI surfaces in a single, synthesised answer.

The competitive field is narrower. The reward, when you get there, is something no organic ranking has ever quite delivered: an implicit endorsement from the tool your potential customer is already trusting to make decisions for them.

Think about how you’ve used AI search recently. You probably didn’t type a keyword and scroll through results. You asked a question – something like “what’s the best digital marketing agency for an e-commerce brand?” or “which SEO tools are worth it in 2026?”… and you got an answer. A reasoned, structured, confident answer which you trust, with names in it. Those names didn’t end up there by accident.

The discovery shift nobody’s talking about loudly enough

User behaviour has changed in a way that most marketing strategies haven’t caught up with yet.

When someone turns to ChatGPT or Perplexity to shortlist suppliers, compare products, or find out who the credible voices in an industry are, they’re not simply browsing – instead in a decisive mode where they will take action. The AI has done the legwork – they’re ready to act on what it tells them.

This is the channel that doesn’t yet show up in most dashboards. It often doesn’t appear in Google Analytics the way a PPC click does. But it’s happening, and it’s influencing decisions at scale. 

What makes a brand get cited by AI?

The honest answer is that this is still being understood industry-wide, but the patterns are becoming clearer.

AI systems (particularly those using Retrieval-Augmented Generation (RAG), which is the dominant approach right now) pull information from across the web, synthesise it, and deliver a response. What they pull from tends to share certain characteristics: it’s authoritative, it’s well-structured, it’s consistent across multiple independent sources, and it’s clearly associated with real expertise.

This is why GEO and SEO are strategies layered within each other, not completely separate. The brands appearing in AI-generated answers tend to be those with strong existing SEO foundations

• good technical health
• credible backlinks
• clear topical authority

You can’t shortcut your way into AI citations by gaming something new; you earn them by being genuinely credible in the first place.

But GEO adds something SEO alone doesn’t address: how your content is structured for extraction, how clearly your brand entity is defined across the web, how consistently named authors and real experts are associated with your ideas, and how widely your credibility is corroborated across sources that aren’t your own site. 

Digital PR matters here in a way it arguably matters more than it ever has, for the kind of independent corroboration that signals to AI systems: this brand is the real thing.

There’s also a dimension around sentiment that makes GEO feel closer to reputation management than traditional SEO ever did. It’s not enough to be cited. What does the AI say about you when it cites you? If your brand appears in answers with caveats, or worse, described inaccurately, that’s a reputational problem playing out at scale invisibly. Monitoring what AI says about your brand is becoming as important as monitoring what people say on social media.

The window to move early is open, but it’s narrowing

One thing we’re seeing consistently is that the businesses investing in GEO now are building citation authority which compounds. Just as domain authority took years to accrue and is genuinely hard for newcomers to replicate quickly, citation authority in AI systems is beginning to work the same way. The brands that are referenced consistently across quality sources are the ones AI is most likely to reach for again.

The brands that act now, building out structured, authoritative, expert-led content with clear entity signals and proper technical accessibility for AI crawlers, are the ones who’ll have a meaningful head start when the rest of the market wakes up.

And to be clear: this doesn’t have to mean blowing up your current strategy. It means layering intentionality about AI visibility on top of what you’re already doing, thinking carefully about how content is structured, who it’s authored by, and how widely your expertise is being recognised beyond your own website.

Where does this leave you?

If you’re not sure how your brand is currently showing up, or not showing up, in AI-generated responses, that’s probably the most important question to start answering. That’s where we can help -if you want to understand where GEO fits into your current strategy and what it would take to start building visibility in this space, we’d love to have that conversation.
