I’m going to give you the honest version of SEO vs GEO, because most of what you’ll read on this topic falls into one of two camps: either “GEO is the future, SEO is dead” (it isn’t), or “GEO is just good SEO with a new acronym” (it isn’t that either). The truth is more nuanced, more interesting, and more commercially important than either extreme.
I’m writing this as someone who runs an SEO consultancy — the literal name of my business is SEO Strategy — and who has spent the last two years watching the data shift beneath my feet. My own brand keyword, “SEO strategy,” is down 70% year-on-year in search volume. “SEO consultant” is down 72%. “WordPress SEO consultant” is down 67%. Meanwhile, “generative engine optimisation” is up 189%. “GEO agency” is up 1,300%. “SEO vs GEO” — the term that probably brought you to this page — is up 2,500%.
Those numbers aren’t abstract to me. They’re my business. So when I tell you that SEO and GEO are different but inseparable, that’s not a diplomatic hedge — it’s a conclusion I’ve reached by watching the transition happen in real time and working out what it actually means for the businesses I serve.
The Data: What’s Actually Happening to Search Volumes
Before we get into what SEO and GEO are, let’s look at what people are actually searching for. These are real UK keyword volumes from our research, not estimates or projections.
Traditional SEO terms in decline. “SEO consultant” at 5,400/month is down 72% year-on-year. “SEO strategy” at 1,600/month is down 70%. “B2B SEO consultant” at 170/month is down 94%. “Featured snippet optimisation” at 10/month is down 100%. These aren’t niche terms — they’re the core vocabulary of the industry I’ve worked in for over 20 years.
AI and GEO terms are exploding. “AI search optimisation” at 140/month is up 1,300% year-on-year with a £28.15 CPC. “GEO strategy” at 70/month is up 600%. “Generative engine optimisation agency” at 70/month has appeared from nothing. “AEO SEO” at 140/month is up 600%. “AI SEO strategy” at 40/month is up 200%. “GEO SEO” at 590/month is up 700%.
The bridge terms are growing fastest. “SEO vs GEO” at 210/month is up 2,500%. “GEO vs SEO” at 390/month is up 875%. “SEO and AI” at 110/month carries a £48.75 CPC — the highest commercial intent in the entire dataset. These are the terms from people asking exactly the question this page answers: what’s the difference, and what do I actually need?
The pattern is clear. People aren’t abandoning the concept of being found online — they’re looking for the version of that concept that accounts for AI. The demand hasn’t disappeared. It’s migrating.
What SEO Is (And What It Still Does Well)
Search Engine Optimisation is the practice of improving your website’s visibility in traditional search engine results — primarily Google, but also Bing and others. It covers technical foundations (can search engines crawl and index your site?), content quality (does your content match what people are searching for?), authority signals (do other credible sites link to yours?), and conversion optimisation (do visitors take action when they arrive?).
SEO has been the backbone of online visibility for over two decades, and despite the declining search volumes for the term itself, the discipline isn’t dying. Google still processes billions of searches daily. Google still refers vastly more traffic to websites than all AI platforms combined. For e-commerce, local services, and any business where the customer journey involves visiting a website, organic search traffic remains the highest-volume discovery channel.
What’s changing is that SEO alone is no longer sufficient. It’s still necessary — you can’t skip the foundations — but it’s no longer the complete picture of how businesses get found.
What GEO Is (And What It Does Differently)
Generative Engine Optimisation is the practice of ensuring your brand is cited and recommended by AI-powered search platforms — Perplexity, ChatGPT, Google AI Overviews, Microsoft Copilot and Gemini. These platforms don’t return a list of links. They generate answers, synthesising information from multiple sources and citing the ones they drew from.
The fundamental shift is this: in traditional search, the goal is a ranking position. In generative search, the goal is a citation. You’re not competing for position three on page one — you’re competing to be one of the three to eight sources the AI selects to build its answer. There is no page two in AI search. There is only cited or invisible.
GEO sits within the broader LLM Optimisation ecosystem alongside AI Overviews Optimisation (AIO) and Answer Engine Optimisation (AEO). The terminology is still settling — you’ll see GEO, LLMO, AIO, AEO and GAIO used across the industry — but they all address the same underlying shift: optimising for AI-generated answers rather than ranked link lists.
The Real Differences Between SEO and GEO
Most comparison articles give you a table with neat columns. Here’s what actually differs in practice, from someone who works across both.
The competition model is fundamentally different. In SEO, you compete for ten organic positions on page one. You can see exactly where you rank, who’s above you, and what they’re doing. It’s a chess game with a visible board. In GEO, the AI generates one answer and cites a handful of sources. You’re either in the answer or you’re not. And unlike rankings, citations are probabilistic — ask the same question twice and the AI might cite different sources each time. This makes GEO harder to measure but also means the competition isn’t as fixed as organic rankings suggest.
Keywords matter less. Entities matter more. SEO has always been partly about keywords — matching the terms people search for with the terms on your page. GEO cares far less about exact keyword matching and far more about entity recognition. Does the AI know your brand exists? Does it understand what you do and what you’re an authority on? Can it distinguish you from similarly named entities? If the AI doesn’t recognise you as a distinct, authoritative entity in your space, your content won’t be cited — regardless of how well it’s keyword-optimised.
Content needs to be citable, not just rankable. A page that ranks well in Google might be too vague for AI citation. Generative engines need content with specific, attributable claims — definitions, statistics, named processes, concrete examples — that the AI can confidently reference. “We offer comprehensive digital marketing solutions” is rankable with enough authority behind it. It’s not citable. “Generative Engine Optimisation increased source visibility in AI responses by 30–40% according to the Princeton study” is citable because it contains a specific claim the AI can attribute.
Measurement is still immature for GEO. SEO has two decades of measurement infrastructure — Google Search Console, rank tracking tools, analytics platforms. You know exactly where you rank, for what, and how that’s changing. GEO measurement is where SEO measurement was in 2008. We can track referral traffic from AI platforms, run manual citation audits, use emerging tools like Otterly and Peec AI, and monitor brand mentions. But there’s no Google Search Console equivalent for AI citations yet. Anyone claiming precise GEO measurement is oversimplifying.
The traffic model is different. SEO drives clicks to your website. That’s the whole point — get people from the search results to your pages. GEO might drive clicks, but it often doesn’t. The user gets their answer from the AI and never visits your site. Instead, your brand gets mentioned, cited, and positioned as authoritative. The value isn’t always a click — it’s brand presence in the answer. For some businesses, being cited as the recommended provider in a ChatGPT response is worth more than a thousand organic visits from people who bounce after five seconds.
Where SEO and GEO Are the Same (The 70% Overlap)
Here’s what the “GEO is completely different” crowd gets wrong: roughly 70% of what makes you visible in AI-generated answers is the same work that makes you rank in Google. The foundations are shared.
Content quality is non-negotiable for both. Thin, generic content doesn’t rank in Google and doesn’t get cited by AI. Comprehensive, authoritative, genuinely useful content ranks well and gets cited. There is no shortcut here for either discipline. If your content doesn’t offer something that five other pages already cover, neither Google nor ChatGPT has a reason to surface it.
Technical foundations matter for both. A site that search engines can’t crawl won’t rank. A site that AI crawlers can’t access won’t be cited. The crawlers are different — Googlebot vs GPTBot, ClaudeBot, PerplexityBot — but the principle is identical: if the machines can’t reach your content, nothing else matters. Page speed, mobile experience, clean architecture — these all serve both disciplines.
Authority compounds across both channels. Backlinks from credible sources help you rank in Google. Those same links and brand mentions become training data for AI systems, strengthening your entity recognition. Digital PR that earns editorial coverage doesn’t just build PageRank — it builds the entity associations that AI platforms use when deciding who to cite. Investment in authority is never wasted because it works for both.
Structured data helps both. Schema markup helps Google generate rich results and helps AI systems parse your content for citation. FAQPage schema, HowTo schema, Organisation schema — these make your content machine-readable for search engines and AI platforms alike.
User experience signals matter to both. Pages that satisfy user intent — low bounce rates, strong engagement, clear answers — perform well in Google and provide the positive signals that AI systems factor into their source evaluation.
This overlap is why the best strategy isn’t “SEO or GEO” but “SEO as the foundation, GEO as the extension.” The work you do to rank well in Google is the same work that makes you citable by AI platforms. You’re not starting over — you’re building on what you’ve already invested.
What SEO Can Do That GEO Can’t
GEO isn’t a replacement for SEO. There are things that organic search visibility does that AI citation simply cannot replicate.
Volume. Google still drives enormously more traffic to websites than all AI platforms combined. For businesses that need volume — e-commerce, publishing, lead generation at scale — organic search is irreplaceable. AI citation might mention your brand, but Google sends the visitors.
Direct website traffic. SEO brings people to your website where you control the experience — the messaging, the conversion path, the retargeting pixel. AI citation might never result in a site visit. For businesses where the website is the conversion engine, SEO delivers the visitors that CRO converts.
Local discovery. “Solicitor near me,” “plumber in Southampton,” “restaurant Winchester” — these queries are still dominated by Google’s local results, map pack and Google Business Profile. AI platforms handle local queries poorly by comparison. If you’re a local business, local SEO is still your primary growth channel.
Measurable, reliable data. Google Search Console tells you exactly which queries drive impressions and clicks, which pages perform, and how that changes over time. That data infrastructure doesn’t exist for GEO yet. If you need precise, reportable metrics for stakeholders, SEO delivers data that GEO currently cannot.
What GEO Can Do That SEO Can’t
Equally, GEO opens opportunities that traditional SEO was never designed to capture.
Brand positioning inside the answer. When Perplexity answers “which SEO agencies specialise in healthcare IT?” and cites your website as a source, you’ve been positioned as an authority by a trusted third party — inside the answer itself. That’s more powerful than a ranking position because the AI has effectively endorsed your expertise to the user. Traditional SEO can get you on the list. GEO gets you into the recommendation.
Visibility without the click. In the zero-click era, being mentioned matters even when nobody clicks through. If an AI assistant tells someone “according to [your brand], the best approach to healthcare IT security is…” then your brand authority has been reinforced regardless of whether the user visits your site. That brand impression has commercial value that traditional SEO’s click-dependent model doesn’t capture.
Reaching users who’ve left Google. An increasing number of people — particularly younger demographics and technical professionals — go to AI platforms first. They ask ChatGPT or Perplexity before they open Google. If you’re only optimised for Google, you’re invisible to this growing segment. GEO captures discovery that happens outside traditional search entirely.
Compounding entity authority. Every AI citation strengthens your brand’s entity signals, which in turn increases the probability of future citations. This creates a flywheel effect that traditional SEO’s link-based authority model doesn’t provide in the same way. Early investment in GEO compounds faster than equivalent SEO investment because the citation patterns are still being established.
Is SEO Dead? The Honest Answer
No. But it’s not the whole answer anymore.
People have been declaring SEO dead roughly once every 18 months since I started working in this industry. Social media was going to kill it. Mobile was going to kill it. Voice search was going to kill it. None of those things killed SEO — they changed it. AI search is the same: it’s not killing SEO, it’s expanding what “being found” means.
The businesses that struggle will be the ones that treat SEO as frozen in 2019 — just keywords, backlinks and technical fixes, pretending AI doesn’t exist. The businesses that thrive will be the ones that recognise SEO as the foundation and GEO as the natural extension. Same goal, broader toolkit, more channels to be visible in.
I kept the name SEO Strategy for my own business despite watching “SEO strategy” decline 70% as a keyword. Why? Because SEO is expanding as an umbrella term. When a client says “I need SEO,” what they increasingly mean is “I need to be found” — and that includes AI search, generative engines, AI Overviews and traditional rankings. The discipline is growing even as the literal keyword shrinks.
A Practical Decision Framework: What Does Your Business Need?
Rather than asking “SEO or GEO?”, ask where your business actually is.
If your website has technical issues, poor rankings, or you’ve never invested in SEO: Start with SEO. The technical and content foundations that drive organic rankings are the same foundations that GEO builds on. There’s no shortcut — AI platforms preferentially cite sources that already have organic authority. Fix the foundations first.
If your SEO is strong but you’re invisible to AI platforms: Add GEO to your existing strategy. You already have the authority and the content — you need to extend it with entity optimisation, structured data for AI parseability, and content restructuring for citability. This is often the most efficient investment because you’re building on existing assets.
If you’re in a B2B or professional services market: Prioritise GEO alongside SEO. B2B buyers are adopting AI search faster than consumers. When a procurement manager asks ChatGPT “which managed file transfer solutions are HIPAA compliant?” or a marketing director asks Perplexity “which agencies specialise in GEO?”, you need to be in those answers. The CPCs in your space tell the story — “AI search optimisation” at £28.15, “SEO and AI” at £48.75, “B2B SEO agency” at £42.05. Where the CPC is high, the commercial intent is real.
If you’re a local service business: SEO first, GEO as a secondary investment. Local SEO — Google Business Profile, local citations, map pack visibility — still drives the majority of local discovery. GEO will become more important for local as AI assistants improve at local recommendations, but the immediate ROI is in local organic visibility.

What This Means for 2026 and Beyond
The direction is clear even if the pace is uncertain. AI search usage is growing. Google is integrating AI Overviews into more queries. New AI platforms are emerging. The share of discovery that happens through AI will increase, and the share that happens through traditional ranked links will decrease.
But “decrease” doesn’t mean “disappear.” Traditional organic search will remain a significant channel for years to come. The shift is additive, not replacement. You need to be visible in Google results and in AI-generated answers. You need content that ranks and content that gets cited. You need backlinks for authority and entity signals for AI recognition.
The businesses with the biggest advantage are those that invest now while the GEO landscape is still forming. The competitive window is open — most businesses haven’t even heard of GEO yet, let alone optimised for it. Establishing citation patterns and entity authority now, while competition is minimal, creates compounding advantages that will be much harder to build once every agency is offering GEO services.
That’s the same argument people made about SEO in 2005 — and the businesses that listened built organic visibility that competitors spent a decade trying to match. The window is the same. The only question is whether you walk through it.
