What is Generative Engine Optimisation (GEO)?
Generative Engine Optimisation, or GEO, is the practice of optimising your content and brand signals so that generative AI tools (ChatGPT, Gemini, Claude, Perplexity, Microsoft Copilot) include and cite you when they generate answers for users.
The difference between GEO and AEO is subtle but useful. AEO is the umbrella term covering any answer engine, including featured snippets, voice assistants, and AI summaries. Generative Engine Optimisation is the more specific subset focused on generative AI: the chatbots that actually write paragraphs from scratch when someone asks them something. If AEO is "get cited," GEO is "get included in the generated text."
The numbers are eye-opening. The GEO market was valued at around $848 million in 2025 and is projected to hit $33.7 billion by 2034. UK senior decision-makers are increasingly using AI in their buying research. Brands that get cited inside AI answers right now compound that advantage for years.
Who Should Choose Generative Engine Optimisation?
Generative Engine Optimisation is not for everyone. It is a strong fit if any of these sound like you.
B2B brands whose buyers research with AI. ChatGPT and Perplexity are now part of the B2B buying journey. GEO is how you appear in it.
Brands competing against bigger names. GEO is one of the few areas where smaller, sharper brands can outrank established ones quickly.
Businesses with strong expertise but weak online presence. GEO turns expertise into citation share.
Companies whose category is fast-moving. GEO rewards fresh, original content. Stale industries reward old content; emerging ones reward GEO.
Anyone with a long sales cycle. Being cited repeatedly during research compounds trust in ways ads can't.

Generative Engine Optimisation FAQs
Isn't Generative Engine Optimisation just SEO with a new name?
No, though there's overlap. GEO requires entity consistency across the open web, content structured for AI extraction (not just human reading), authority building in sources AI training pipelines pull from, and structured data that goes deeper than typical SEO.
Which AI platforms should I prioritise for GEO?
Depends on your customers. For UK B2B and professional services, ChatGPT and Perplexity carry the most weight right now. For consumer searches, Google AI Overviews matter most. For technical industries, Claude is increasingly relevant. We audit where your customers are actually using AI before recommending where to focus.
Can I track ROI from Generative Engine Optimisation?
Yes, more than people realise. AI-referred traffic in analytics, citation appearances via tools like Profound and Otterly, share of voice across AI platforms, and the conversion rate of AI-referred visitors. Conversion rates from AI tend to be significantly higher than standard organic.
How quickly will I see results from GEO?
Structural changes can show in AI answers within days or weeks. Building authority in AI training data is a longer game (3 to 12 months for meaningful share of voice). We deliver quick wins alongside the long-build work.
