The short answer
Traditional SEO (search engine optimisation) is about getting a page to rank in a list of results, the familiar blue links and the local map pack, so someone clicks through to your website. GEO (generative engine optimisation) is about getting your business named, quoted or recommended inside the answer an AI tool writes, whether that's Google's AI Overviews, ChatGPT, Gemini, Perplexity or Claude.
The neat way to hold the distinction in your head: SEO ranks pages, GEO influences answers. One competes for a position in a list; the other competes to be one of the handful of sources an AI decides to trust and cite. They are not rivals and one does not replace the other. In practice they lean on a lot of the same groundwork, which is exactly why treating them as an either/or choice is a mistake.
SEO and GEO at a glance
The distinction in one view. Every row below is expanded on later in this guide.
| Traditional SEO | Generative Engine Optimisation | |
|---|---|---|
| What you compete for | A position in a list of results | A mention inside a written answer |
| How many winners | Ten organic results plus three map slots | Usually one to three named sources |
| What success looks like | A click through to your site | Being named, quoted or recommended |
| How the visit arrives | Directly from the results page | Often no click at all — or a branded search later |
| Content that wins | Matched to search intent, well linked | Directly answerable, specific, quotable |
| Authority signal | Links from reputable sites | Corroboration across trusted sources, including unlinked mentions |
| Indexes involved | Effectively one (Google, or Bing) | Several, each sourcing differently |
| Measurement | Rankings, impressions, clicks, CTR | Whether you are named, and what gets cited |
| Maturity | Two decades of settled practice | Emerging — tooling and norms still forming |
The single most useful line in that table is the second one. Ten organic results and three map slots give you thirteen ways to be seen; an AI answer that names three businesses gives you three. The competition is narrower, which cuts both ways — harder to get in, far more valuable once you are.
What traditional SEO optimises for
SEO aims to earn a high position when someone types a query into a search engine. The mechanics are well understood after two decades: relevant content matched to search intent, sensible use of keywords, a technically sound and fast site, and authority signals, chiefly links from other reputable sites. For a local business, that also means a complete Google Business Profile, consistent name, address and phone details across the web, and genuine reviews, all of which feed the local map results.
The payoff is a click. Someone sees your listing, chooses it over the other results, and lands on your site where you control the message and can turn a visitor into an enquiry. That model still matters enormously: Google remains the dominant way people search, holding around 90% of the UK market according to StatCounter, so ranking is far from dead.
What GEO optimises for
GEO works backwards from how generative engines actually answer. Instead of returning ten links, an AI reads across multiple sources, then writes one merged reply and cites only a few of them, often just one to three. Your goal shifts from ranking a page to being one of those cited or mentioned sources, and ideally being recommended by name.
That rewards slightly different things. AI systems favour content that is clearly structured, directly answers a specific question, and backs claims with concrete detail, facts, figures, prices, specifics, rather than vague marketing copy. Clear headings, straightforward FAQ-style answers and structured data (schema) all help a machine extract and reuse your information. Being referenced elsewhere, in directories, reviews and reputable third-party sites, builds the 'entity' picture an AI draws on when deciding who to trust.
The catch worth being honest about: this field is young. Measurement is patchy, the platforms change their behaviour often, and many of the eye-catching statistics circulating come from vendors rather than independent research. Treat confident-sounding numbers with healthy scepticism.
Where they overlap (more than you'd expect)
The good news for anyone dreading a second discipline: strong SEO is the foundation GEO is built on. Google's AI Overviews draw heavily on pages that already rank in the top organic results, so ordinary ranking work directly feeds AI visibility. The signals that have long mattered for SEO, genuine expertise and trustworthiness (what Google calls E-E-A-T), a crawlable and well-structured site, and clear, accurate content, are the same signals that make content easy for an AI to quote.
- Content quality and topical depth help both.
- A technically clean, crawlable site is a prerequisite for both.
- Structured data and clear headings aid ranking and make you easier to cite.
- Reputation and mentions across the web build authority for search and AI alike.
- For local businesses, an accurate Google Business Profile underpins both map results and AI recommendations.
Where they genuinely differ
The overlap is real, but so are the differences, and pretending GEO is just SEO with a new name does no one any favours.
- Outcome: SEO wins a click to your site; GEO wins a mention or citation inside an answer, often with no click at all.
- Competition: SEO competes for one of ten link slots; GEO competes to be one of only a few cited sources.
- What's rewarded: SEO leans on keywords and backlinks; GEO leans on answer completeness, clear structure and extractable facts.
- Format of content: AI engines prefer direct, self-contained answers over long, meandering pages.
- Measurement: SEO has mature tools and clear metrics; GEO visibility is harder to track and the tooling is still maturing.
How each AI platform actually finds its answers
“AI search” is not one thing. The engines source differently, which changes what you should actually do. Treat the detail below as current rather than permanent — this moves quickly.
- Google AI Overviews lean on Google’s own index. If you already rank well organically you are in the candidate pool, so ordinary ranking work feeds directly into AI visibility.
- ChatGPT uses two separate mechanisms. Its search feature fetches live pages to cite; a different crawler gathers content for training. One decides whether you get cited today, the other shapes what the model knows unprompted. Blocking one does not block the other.
- Perplexity retrieves live and displays its sources prominently, which makes it the easiest place to check whether you are being cited at all.
- Gemini draws on Google’s index, with a separate control governing whether your content is used for grounding and training.
- Microsoft Copilot leans on Bing. This is the one most UK businesses overlook — if you have never checked whether Bing indexes your site properly, that is a genuine and cheap gap to close.
One practical warning from our own work: a surprising number of sites block AI crawlers by accident, and not in robots.txt where you would look. Hosting-level bot protection can drop those requests before they ever reach your site, with nothing in your access logs to show for it. We found exactly this on a site we run — several major AI crawlers were being refused at the firewall while ordinary search bots passed through untouched. It is worth testing rather than assuming.
How do you actually measure GEO?
Honestly: less precisely than SEO, and anyone telling you otherwise is overselling. Rank trackers cannot see inside a generated answer, and the same question can return different answers to different people on different days. What follows is what genuinely works today.
- Ask the assistants directly, on a schedule. Take the ten questions your customers actually ask, put them to ChatGPT, Perplexity, Gemini and Copilot on a repeating basis, and record three things: are you named, who is named instead, and which sources the answer cites. That last column is the most actionable data in GEO — it tells you exactly which sites to get mentioned on.
- Watch branded search. GEO influence often shows up indirectly. Someone gets a recommendation from an assistant, then searches your name. A rise in branded impressions in Search Console with no other obvious cause is a reasonable signal.
- Check referral traffic. Visits from assistant domains appear in analytics as referrals. The volumes are typically small, but they are real and they are a floor, not a ceiling — most AI influence never produces a click at all.
- Track the citations, not just the mentions. If an answer recommends you but cites a directory rather than your site, that directory is doing the work. That is useful to know.
Set a baseline before you change anything. Without one you cannot tell improvement from the natural variance in how these systems answer.
Why a local business needs both
It is tempting to pick a side, but the behaviour of real customers rules that out. In the UK, a large and growing share of searches now end without a click, and searches that trigger an AI Overview are especially likely to be answered on the results page itself. If you only chase clicks, you are invisible in the growing number of moments where the answer, and the recommendation, happens before anyone reaches a website.
At the same time, ranking still delivers the clicks that turn into enquiries, and AI recommendations often lean on businesses that already rank and have a solid local presence. Crucially, doing well in Google Maps does not automatically get you recommended by an AI. You can test this yourself in about two minutes: search your category and town in Google, note who holds the map pack, then ask ChatGPT or Perplexity the same question in plain English. The two lists frequently disagree. Where they disagree is your opportunity, and it is why the two need tending separately even though they share roots.
For a local firm, the practical reading is simple: keep doing the local SEO that earns visibility and clicks, and add the GEO layer, clear answers, structured content, consistent business details and genuine reviews, that makes an AI comfortable naming you. This is exactly the joined-up approach we take for clients at GEO SEO, rather than selling one at the expense of the other.
Where to start, in order
GEO work has a natural sequence, and doing it out of order wastes effort. Roughly:
- Check the AI crawlers can reach you. Everything else is pointless if they cannot. Test it rather than trusting robots.txt.
- Make your facts consistent and machine-readable. Same name, address and phone everywhere; proper organisation and service schema; a Google Business Profile that agrees with your website. AI systems look for corroboration before naming anyone, and inconsistency reads as uncertainty.
- Get genuine reviews. When an assistant recommends a local business it is synthesising what other people said about you. Nothing else substitutes for this.
- Restructure your key pages to answer questions directly. The answer up front, specific detail, clear headings, real figures. Content written to be extracted reads differently from content written to rank.
- Build presence in the sources these systems actually retrieve from. A narrower set than Google ranks — established directories, review platforms, industry bodies, local press.
- Then measure, using the baseline method above.
Notice how much of that is ordinary local SEO done properly. That is the honest headline of this whole guide: for most local businesses, GEO is less a new discipline than a reason to finally finish the fundamentals. When we took a Broadstone jeweller from not ranking at all to number one for ‘jewellery’ — 135,000 searches a month — none of it was AI-specific work. It was structure, profile alignment and genuine depth: the same foundations an AI needs before it will name you.
Myths worth busting
A few claims are doing the rounds that deserve a firm, honest correction.
- "GEO replaces SEO." No. GEO is built on SEO foundations; neglect ranking and your AI visibility usually suffers too.
- "There's a secret GEO trick." Mostly it's disciplined fundamentals, clear, accurate, well-structured, trustworthy content, not a hack.
- "SEO is dead." Google still handles the overwhelming majority of UK searches; clicks still matter.
- "You can precisely measure AI citations." Not reliably yet, be wary of anyone promising exact numbers.
- "Do it once and you're set." AI engines change often and rebuild answers frequently; visibility needs maintaining.
