Generative Engine Optimisation (GEO) in the UK

Generative Engine Optimisation (GEO) is the practice of structuring your website, content and off-site signals so that large language models (ChatGPT, Perplexity, Gemini, Claude) name your business when buyers ask category-defining questions. In the UK, GEO sits alongside SEO as the second visibility layer: SEO wins Google blue links, GEO wins the spoken or summarised answer that comes before the click.

Why GEO matters for UK businesses in 2026

UK B2B buyers increasingly start research in ChatGPT or Perplexity rather than Google. When an AI engine answers 'who are the best AI consultants for UK insurance?' or 'recommend a customer service automation partner', it names two or three businesses and ignores the rest. If you are not in that shortlist, you have lost the deal before you knew it existed.

GEO closes that gap. It is the discipline of making your business legible, citable and authoritative to the engines that now sit between you and your buyer.

What GEO actually involves

  • Direct-answer content: every key page opens with a clear 40 to 60 word summary the engine can lift verbatim
  • Structured data: FAQ schema, HowTo schema, Organization schema and BreadcrumbList markup on every important page
  • llms.txt and robots.txt: explicit signals to AI crawlers about what to index and how to attribute your business
  • Citation strategy: earning mentions on industry publications, Wikipedia, LinkedIn and trusted directories that AI models weight heavily
  • Topical clusters: building depth around a defined topic so engines recognise you as the authority, not a one-page result
  • Measurement: running a defined prompt set across the major engines monthly to track mentions, citations and competitive share

GEO vs SEO: how they differ in practice

SEO optimises for Google's blue-link algorithm. GEO optimises for how language models read, summarise and cite. Three concrete differences:

1. Format. SEO rewards comprehensive long-form content. GEO rewards clear, lifted-friendly paragraphs and well-structured facts.

2. Authority. SEO weights backlinks. GEO weights citation diversity across trusted sources the models train on or retrieve from.

3. Measurement. SEO measures keyword rank. GEO measures whether your brand is named in answers, and which sources the engine cites.

You need both. GEO without SEO leaves you invisible on Google; SEO without GEO leaves you invisible in AI answers.

Where UK businesses should start

  • Run an AI visibility audit to find where you currently appear and where competitors beat you
  • Add direct-answer paragraphs and FAQ schema to your top 10 commercial pages
  • Publish a topical cluster of 6 to 12 deep articles around your category
  • Earn citations on 3 to 5 UK industry publications relevant to your sector
  • Set up monthly tracking of a 20 to 40 prompt set across ChatGPT, Perplexity and Gemini

How this plays out in UK motor claims

We ran a 32-prompt test for a UK accident management business across ChatGPT, Perplexity and Gemini. They appeared in 0 of 32 answers. Two competitors appeared in 18 and 14 respectively. Six weeks after a focused GEO programme (direct-answer rewrites, FAQ schema sitewide, an llms.txt file, two earned guest articles on Insurance Times and Modern Insurance) they appeared in 11 of the 32 prompts. The site itself barely changed for human visitors. What changed was its legibility to the engines now mediating buyer decisions.

Frequently Asked Questions

Is GEO the same as AEO?

Effectively yes. GEO (Generative Engine Optimisation) and AEO (Answer Engine Optimisation) describe the same discipline from different angles. GEO emphasises the engines (ChatGPT, Perplexity, Gemini). AEO emphasises the output (the answer itself). The tactics are largely identical.

How long does GEO take to show results?

Faster than SEO. We typically see initial mention gains in 4 to 8 weeks because LLMs re-index and re-train on a shorter cycle than Google updates rankings. Sustained share-of-voice takes 3 to 6 months.

Do I need to abandon SEO?

No. SEO still drives a significant share of UK B2B traffic. GEO is additive. The good news is that most GEO improvements (clearer content, schema, citations) also help SEO.

Can I do GEO in-house?

Yes, partially. Direct-answer rewrites, FAQ schema and llms.txt are within reach for most in-house teams. The audit, prompt-set design and citation strategy benefit from outside expertise because they require category-level pattern recognition across many engines and competitors.

How do I measure GEO success?

Run a fixed prompt set monthly across the major engines. Track three numbers: how often your brand is named, which sources the engine cites for your category, and your share-of-voice versus named competitors.
