Expanding on Point 05 from The 2026 Marketing Playbook
I wrote at the start of 2026 that GEO – Generative Engine Optimisation – was the acronym that would actually stick. Six months in, the debate has moved on. It’s not whether GEO matters. It’s whether your brand has started taking it seriously yet.
Most haven’t.
What changed in search?
For roughly two decades, the game was consistent. Understand how Google ranks content, build your site accordingly, earn links, climb the results page. The rules shifted constantly at the margins, algorithm updates, mobile-first indexing, but the underlying model stayed the same. A ranked list of ten blue links. Visibility meant appearing near the top.
That model is changing
Google’s AI Overviews now appear on a significant proportion of searches, surfacing a synthesised answer before the user ever reaches an organic result. ChatGPT’s search functionality has crossed 1 billion web searches per week. Perplexity has built a growing user base specifically among high-intent, research-led audiences.
And the logic of how you get cited in those answers is materially different from the logic of how you get ranked in a traditional SERP.
Why traditional SEO isn't enough
Traditional SEO optimises for ranking signals, so keyword relevance, backlink authority, page speed, structured data. All of that still matters, but it is a partial answer to a bigger question. Generative engines not only ranks, but synthesises content. Drawing on sources it deems credible, authoritative, and clearly structured, and producing an answer that may not include a link to your website at all.
The implication is uncomfortable for anyone who has spent years optimising for click-through rates. Visibility in a generative result might look like your brand being named, your product being recommended, or your perspective being quoted but without a single trackable click. The metric changes before the strategy does, and most measurement frameworks haven’t caught up.
The SEO agencies and in-house teams that thrive in this environment are the ones that evolve their practice, not the ones that keep doing the same thing and hope AI Overviews go away. Understanding how to structure content so that a generative model can extract and surface it is not the same as understanding PageRank. Both matter, but they are not the same job.
What GEO actually requires
The honest answer is that the playbook is still being written. At Charlie Oscar, we’re in early stages of experimentation alongside clients, and anyone who tells you they’ve cracked it definitively is probably selling something.
What’s becoming clear is this: generative engines reward clarity, authority, and specificity. Content that answers a question precisely, that demonstrates genuine expertise, that cites credible sources and is structured in a way that a model can parse, performs better than content written primarily to hit keyword density targets. E-E-A-T — Experience, Expertise, Authoritativeness, Trustworthiness – which Google introduced as a quality signal years ago, has become more important.
Brand visibility also plays a different role in this environment. A brand that is widely referenced, discussed, and cited across the web (not just on its own properties) is more likely to surface in generative answers. Earned media, thought leadership, PR, and third-party coverage contribute to GEO in ways they never fully contributed to traditional SEO. The disciplines that were always connected in theory are now connected in practice.
The industry reckoning
New roles are emerging. New agencies are being built around this specific problem, and the specialist GEO market is growing precisely because the gap is real and the existing skillset doesn’t fully bridge it.
For brands, the question isn’t whether to engage with GEO. The question is whether to wait until competitors have established a presence in these environments and then play catch-up, or to start building now when the landscape is still relatively open.
Traditional SEO took a decade to become a serious discipline with a serious budget behind it. GEO will not have that runway. The pace at which generative search is growing means the window for early-mover advantage is shorter than most people assume.
Start before you're ready
The brief for 2026 is straightforward; treat GEO with the same seriousness you eventually gave SEO, but without waiting a decade to do it.
Audit how your brand currently appears, or doesn’t, in ChatGPT, Perplexity, and Google AI Overviews. Ask what questions your target customers are putting into these tools and whether your content can credibly surface as an answer. Start building the content, the authority signals, and the cross-channel presence that generative engines reward.
