If you already run traditional SEO and you are wondering whether generative-engine optimisation (GEO) replaces it, the answer is no. GEO builds on the same foundations, then adds a handful of habits that help your pages get quoted inside AI answers rather than just ranked in a list of links.
That matters for UK service businesses, because more people now start their search inside an AI answer. Ofcom found that around one in five UK adults use generative AI to keep up with the news, and the habit is spreading to how people research services too. So the practical question is not SEO versus GEO. It is: what do you keep doing, and what do you add.
Same engine underneath
Here is the part most confusion comes from. AI answers in Google are not a separate system bolted on the side. Google is explicit that its generative features are rooted in its core Search ranking and quality systems, using a technique called retrieval-augmented generation (also known as grounding) to pull content from the same Search index.
The knock-on effect is simple. To be eligible to appear as a supporting link in AI Overviews or AI Mode, a page has to be indexed and eligible to show in ordinary Search with a snippet. There are no extra technical requirements and no special optimisations. If your SEO fundamentals are weak, no amount of GEO tinkering will save you. Good crawlability, fast pages, clear structure, helpful content and honest expertise are the entry ticket for both.
What GEO genuinely adds
So if the foundation is shared, what is actually different about optimising for a generative engine? The shift is subtle. A ranked link only has to be relevant and trustworthy enough to earn a click. To be quoted inside an answer, your content has to be easy for a model to lift a clean, self-contained statement from and attribute confidently.
In practice that means a few concrete things layered on top of good SEO:
- Answer the actual question near the top of the page, in a sentence that stands on its own without the surrounding paragraph.
- Support your points with figures, dates and named sources, so the claim is verifiable rather than vague.
- Show first-hand experience. Google’s quality guidelines reward content that demonstrates actual use of a product, a real visit or a genuine experience, which is exactly the tone models tend to trust and quote.
None of this replaces SEO. It is closer to writing your existing content a bit more like a reference than a brochure. We go deeper on the writing side in writing service content that AI answers can cite, and on the broader tactic in getting cited in AI answers.
What we see with UK service businesses
Beyond the official guidance, a pattern is worth naming. For a local service business, the pages that get pulled into AI answers are rarely the glossy homepage. They are the plain, specific ones: a clear service page that states what you do, who for and in which areas, or an honest explainer that answers a question a customer actually asks before they enquire.
The reason is practical. A generative engine wants to give a confident, specific answer to a specific query. “Do you cover evening call-outs in Colchester?” is answered far better by a page that says so in plain words than by a page selling a mood. So the businesses winning here are not the ones chasing GEO tricks. They are the ones who wrote genuinely useful pages, kept them accurate, and made the important facts easy to find. That is also why local SEO and GEO reinforce each other so cleanly. The same clarity that helps you get found nearby in local search is what makes your pages quotable.
Myths worth ignoring
A cottage industry has grown up around GEO, and some of its advice is simply wrong for Google. You do not need to create special AI text files, add exotic markup or convert everything to Markdown. Google Search does not use them. You also do not need to chop your content into tiny fragments. Google’s systems can understand a page covering several topics and surface the relevant part.
Two more traps. First, do not spin up a separate page for every possible phrasing of a query. Creating content mainly to manipulate generative answers falls foul of Google’s scaled content abuse policy. Second, be wary of tools that promise AI ranking success or claim to use Google’s internal metrics. No third-party tool has access to those systems. Structured data is still worth doing, but follow Google’s own documentation as the definitive guide rather than generic advice.
And to settle a common worry: using AI to help write is not against the rules. Using automation to generate content primarily to manipulate rankings is. The line is the same one that has always applied. Is this genuinely useful to the reader.
How to know if it is working
You can now measure AI visibility rather than guess. Google added a Generative AI performance report in Search Console, which shows how your content performs in AI features on Search. Combined with your normal performance data, it tells you whether your changes are landing. If you are not yet comfortable in Search Console, start with our business owner’s guide to Google Search Console, then add the AI report to your monthly check.
Where to put your effort
Do SEO properly first. It is the foundation both classic results and AI answers stand on. Then layer the GEO habits onto the pages that matter most: your core service pages and the questions people ask before they buy. You are not running two campaigns. You are doing one thing well and making sure the useful bits are easy to lift.
This is the work Kilij Digital does as part of SEO and generative-engine optimisation for service businesses. The outcome we are after is specific. The person searching for an emergency call-out at 9pm, or comparing a couple of clinics before booking a consultation, finds your page, gets a straight answer, and enquires, whether that answer arrives as a blue link or a quoted line inside an AI response. And once they enquire, the same care needs to carry through to how fast you reply.
