I get asked some version of this question on nearly every discovery call I run now. A marketing director will say something like “we’ve got SEO covered, do we actually need this GEO thing as well, or is it just the same work with a new name.” It’s a fair question, and I’d rather give you an honest, detailed answer than a sales pitch dressed up as one.
I run Essheo, a search marketing agency working across the UK and US, and before that I spent years building acquisition systems in some of the toughest sectors going, competing against price comparison giants with marketing budgets most businesses could never match.
So I’ve watched search evolve from the inside for a long time, and what I can tell you plainly is that SEO and GEO are related, but they are not the same discipline. Confusing the two, or assuming one replaces the other, is exactly how businesses end up with gaps in their visibility that a competitor quietly slips into.
What Actually Is the Difference Between SEO and GEO?
The simplest way I explain it on calls is this. SEO optimises your website to rank inside a list of links on a traditional search results page. GEO optimises your content and brand presence to be cited, quoted or recommended inside the answer an AI system actually writes, whether that’s ChatGPT, Gemini, Claude, Perplexity or Google’s own AI Overviews. One is about earning a position. The other is about earning a mention.
That distinction sounds subtle until you look at what each discipline actually measures. SEO success is judged on rankings, organic sessions, click-through rate and conversions from that traffic. GEO success is judged on citation frequency, share of answer, brand mentions inside AI conversations, and whether your business gets represented accurately when someone asks an AI system a relevant question.
You can rank first on Google for a term and still never get mentioned when someone asks ChatGPT the exact same question. I’ve seen that happen to clients before we started working with them.
How Do the Ranking Signals Actually Differ?
Traditional SEO leans heavily on things like backlink volume, keyword targeting, site speed, technical crawlability and on-page optimisation. GEO cares about a different mix. Structured, clearly written content, direct quotability, credible sourcing, consistent brand mentions across trusted third-party platforms, and how well an AI model can extract a clean, accurate answer from your page.
Backlinks still help in GEO, but they behave more like credibility references than the core ranking currency they’ve always been in classic SEO.
I think the clearest way to put it is that ranking factors help a page get seen inside a list of search results, while citation factors help a brand get reused inside a generated answer. Those are genuinely different jobs, even though good foundational content quality tends to support both at once.
Does One of Them Drive More Clicks Than the Other?
Traditional SEO still drives the clear majority of website discovery traffic. Current estimates put traditional search at roughly 40 to 60% of overall discovery traffic, with AI platforms currently accounting for under 5%.
That gap matters, and I always tell prospective clients this honestly rather than overselling GEO’s current reach. GEO drives what’s often called zero-click brand authority and AI-referred traffic, meaning the value frequently comes from being recommended without a click ever happening, rather than from direct sessions landing on your site.
That doesn’t make GEO less important. It makes it a different kind of important. If a user asks an AI assistant to compare boiler brands, or find the best air source heat pump installer in their area, and your business never gets mentioned in that answer, you’ve lost the enquiry before your website ever had a chance to earn the click.
I’d argue that’s a more dangerous form of invisibility than sitting on page two of Google, because at least page two still gets seen by someone scrolling.
Is GEO Actually Replacing SEO?
No, and I say this to every client who asks, because I think agencies overselling GEO as a total replacement for SEO are doing their clients a genuine disservice. Google’s own AI features still surface links inside AI Overviews and AI Mode, and Google itself continues to recommend that site owners review fundamental SEO best practices as the foundation for AI visibility.
SEO remains the gateway that makes GEO possible in the first place.
Why Does SEO Still Come First in the Process?
Think of it this way. SEO controls your discoverability infrastructure, meaning whether your site gets crawled, rendered, indexed and understood at all. GEO then targets whether an AI system, synthesising an answer from multiple sources it has already found and understood, chooses to select and cite yours specifically.
If your technical SEO foundations are weak, an AI system may never properly crawl or understand your content in the first place, which means there’s nothing for GEO to build on top of.
I’d compare it to building a house. SEO is the foundation and structure. GEO is how well the house gets described and recommended once people can actually see it properly. You genuinely can’t skip straight to the second part.
What Happens If a Business Only Focuses on One?
I’ve seen both mistakes play out with prospective clients before they came to us. A business with strong traditional SEO but zero GEO strategy tends to keep its Google rankings for a while, but slowly becomes invisible in the exact AI-driven conversations where its customers are increasingly starting their research, especially for comparison and recommendation-style queries.
A business chasing GEO with no SEO foundation, on the other hand, often struggles to get indexed properly at all, because the crawling, structure and technical fundamentals that get a page found and understood haven’t been built.
Search Engine Land put it well when they described GEO as what happens when search becomes multi-platform and multi-modal rather than confined to one channel. It isn’t a rival discipline to SEO. It’s what SEO has to expand into as discovery genuinely fragments across more surfaces.
Do You Actually Need Both SEO and GEO?
Yes, and I’d be doing you a disservice if I said otherwise just to make a sales point. Every credible piece of research I’ve reviewed on this lands in the same place. GEO extends SEO to a new surface. It doesn’t replace the underlying infrastructure SEO has always provided.
How Do SEO and GEO Actually Work Together in Practice?
In our own work at Essheo, we don’t treat these as two separate service lines fighting for budget. We treat them as one connected system. Strong technical SEO, clean site architecture, proper schema markup and genuinely useful, well-structured content give AI systems the clearest possible signal about who you are and what you offer.
That same foundation then gets extended through GEO-specific work: building citation-worthy content with real statistics and credible sourcing, establishing presence on the third-party platforms AI models actually trust like Reddit, YouTube and industry publications, and keeping content fresh enough that it keeps earning citations rather than losing them over time.
This is exactly why we describe what we do as search everywhere optimisation rather than just SEO or just GEO. Google as a sole channel isn’t sustainable any more, and treating AI visibility as a bolt-on afterthought isn’t sustainable either. Both need building properly, together, from the same strategic foundation.
What Should a Business Prioritise First?
I’d never tell a business with genuinely weak technical SEO to skip straight to chasing AI citations. Get your crawlability, site structure, page speed and core content quality right first, because that’s the shared foundation both disciplines depend on.
From there, I’d focus on auditing where you currently stand in AI platforms, since most businesses genuinely don’t know whether ChatGPT, Gemini or Perplexity mention them at all. Then build out citation-worthy content and third-party presence alongside your ongoing SEO work, rather than as a separate project running on its own timeline.
I’d also say this plainly: don’t expect instant results from either discipline done properly. We structure our own client engagements around 12 and 18 month growth strategies because genuine topical authority, the kind that compounds across both traditional rankings and AI citations, takes sustained, consistent work. Quick wins can and should happen in the first few months, but the real defensible advantage builds over time.
Which Approach Is Right for Your Business?
I think the honest answer is that this depends far less on your industry and far more on how your customers actually search. If you’re in a category where people compare options, ask for recommendations, or research before buying, which describes most competitive sectors I’ve worked in, then your customers are almost certainly already asking AI tools some version of those questions, whether or not your business currently shows up in the answer.
At Essheo, every practitioner on our team carries 8 plus years of experience ranking in genuinely hard sectors against household name competitors and billion-pound comparison sites.
That same experience is exactly what transfers into building GEO strategies that actually work, because the underlying discipline, understanding what earns trust and authority in a specific space, hasn’t changed. What’s changed is the number of platforms that trust signal now needs to reach.
Our clients have generated over £45 million in combined revenue over the last two years through search marketing systems built on that exact principle: proper foundations, extended properly across every channel that matters.
Ready to Find Out Where You Actually Stand?
If you’ve read this far, you’ve probably already sensed that “SEO or GEO” is the wrong question to be asking your team. The right question is whether your current strategy covers both properly, and whether you actually know where your business stands in AI-driven search right now, rather than assuming your Google rankings tell the whole story.
We start every client relationship with honest discovery and analysis, finding out exactly where your ideal customers are searching today, across Google, AI platforms, YouTube and social channels, and where the gaps sit compared with your competitors.
From there we build a tailored roadmap that covers both the SEO foundations and the GEO strategy on top of them, designed to deliver quick wins early while compounding into genuine long-term authority. You can have us run this hands-off with regular reporting, or work hands-on alongside your team, entirely your choice.
I’d rather have that honest conversation with you now, while there’s still a genuine first-mover advantage to be had in most sectors, than have you find us in a year having watched a competitor take that ground instead.
