GEO vs SEO: what's the difference?

SEO (search engine optimisation) is the practice of getting a page to rank in traditional search results; GEO (generative engine optimisation) is the practice of getting a business mentioned and cited inside AI-generated answers from tools like ChatGPT, Perplexity and Google's AI Overviews. They're not rival disciplines — GEO is built directly on top of the same crawlable, well-structured, trustworthy content that good SEO produces, aimed at an extra goal: being quotable, not just rankable.

What does SEO optimise for that GEO doesn't?

Traditional SEO's job is to win a position in a list — get a page onto page one, then as high in the ten blue links as possible, because position strongly predicts click-through. That means SEO cares about things GEO barely touches: title tags and meta descriptions written to earn a click from a results page, URL structure, page speed, backlink authority, and the sheer breadth of keywords a site can rank for. None of that changes under GEO — a page still has to be crawlable and competitive to be in the running at all. What SEO doesn't optimise for is what happens after the click never comes, because an AI system answered the question itself.

What does GEO add that SEO doesn't cover?

GEO optimises for being lifted and cited rather than clicked. That's a different job: a direct, complete answer in the opening lines rather than a scene-setting introduction; headings phrased as the actual questions people ask; schema markup that states plainly what a business is, does and charges, so an AI system doesn't have to infer it; and consistent facts across a website, Google Business Profile and directories, because assistants cross-check sources and quietly drop the ones that disagree with each other. Full detail on what that work looks like in practice is in our guide to what generative engine optimisation actually involves.

Do you need to choose between GEO and SEO?

No — and treating them as a choice is the most common mistake we see. Skip the SEO fundamentals and there's nothing crawlable for an AI system to find in the first place; skip the GEO layer and what it finds is harder to quote cleanly, so a competitor's better-structured page gets the citation instead. Every AI system that composes answers is still drawing on the same underlying index that ranks organic search — Google's own AI Overviews pull overwhelmingly from pages that already rank well. GEO doesn't replace ranking well; it decides who gets quoted among the pages that do.

	Traditional SEO	GEO (generative engine optimisation)
Primary goal	Rank high enough to earn the click	Get mentioned or cited in the AI-generated answer
Success signal	Position, organic traffic, click-through rate	Being named in AI answers, AI-referred traffic, AI Overview appearances
Content shape that wins	Comprehensive, keyword-relevant, earns backlinks	Direct answer up front, structured, easy to extract a clean quote from
Key technical lever	Site speed, crawlability, backlink authority	Schema markup, llms.txt, business-data consistency across the web
Measurability today	Mature — rank trackers, Search Console, GA4	Partial — some AI-referral and AI Overview tracking exists; no reliable "AI rank" metric yet

Is GEO just a rebrand of SEO?

Partly fair, and worth saying honestly: a lot of what gets sold as "GEO" is standard technical SEO with a new label — clean markup, clear structure and crawlable pages have always been good practice. What's genuinely new is the target. SEO never had to worry about a system silently rewriting your answer to a question in someone else's words with no click attached; GEO exists because that's now routine. So GEO isn't a different set of tools so much as the same fundamentals pointed at a new, less controllable surface.

How do you know if you need GEO yet?

A quick, free test: ask ChatGPT or Claude to recommend a business in your category and town, and see whether you're named. If competitors show up and you don't, that's your answer. It matters more the more your customers research by asking rather than searching — which, for most local service businesses, is already a meaningful and growing share of enquiries, even if it's not yet the majority.

What doesn't work — an honest counterpoint

Be sceptical of anyone selling "GEO" as a separate, precisely trackable discipline with guaranteed placements — the tooling to measure "AI rankings" the way rank trackers measure Google positions doesn't reliably exist yet, and no one can promise a specific citation the way they might promise a keyword ranking. GEO today is closer to good practice applied early than a measurable campaign with a scoreboard. That's not a reason to ignore it — early, consistent machine-readability compounds — but it is a reason to be wary of anyone pricing it like SEO used to be priced in 2015, with guarantees attached.
