We help British ecommerce, B2B SaaS, fintech and multi-location businesses become the brand that ChatGPT, Google AI Overviews and AI Mode, Gemini, Perplexity, Copilot and Claude recommend when buyers ask what to choose.
Trusted by brands across Britain, Europe and the US to win visibility in generative search.
A buyer asks ChatGPT for "the best … in Britain" or "… near me in London", and the reply names your competitor.
Google's generated summaries now sit above the organic results for your category's questions, so page-one rankings bring fewer clicks.
Assistants quote Reddit threads, Trustpilot reviews and comparison sites about your market, and you're in none of them.
Your SEO provider started calling its monthly report "answer engine optimisation", yet the work itself looks exactly the same.
You have no idea how often Gemini, Perplexity or Copilot mention you, or what they say when they do.
Chatbots repeat old prices, closed locations or discontinued products, and there is no obvious way to correct them.
If this sounds familiar, you need an AEO agency UK brands can verify, one that measures the replies buyers actually see as well as the rankings.

The SEO side is covered by our AI SEO services; the GEO side, by LLM SEO.
Most case studies in our industry ask you to trust a screenshot. Each result below comes with a query you can run yourself, and checking it takes under a minute.
748 new paying signups per month
Problem: Strong Google rankings, completely invisible in generated replies about wholesale grocery. We rebuilt category pages for LLM extraction and fixed the technical gaps keeping them out of reach. Sixteen months later, 748 new paying signups per month come through assistant-driven discovery.
Solution: Ask ChatGPT about wholesale grocery platforms in Thailand and see who it recommends.
56 booked sales calls per month
Problem: Dozens of regional sites, product data scattered everywhere, no coherent entity presence for models to pull from. We consolidated schema, aligned knowledge-graph data and ran a full technical cleanup. Result: 56 booked sales calls per month, client-confirmed. Every one of those calls is pipeline.
Solution: Ask Gemini about enterprise cybersecurity solutions and check who shows up first.
4 new enterprise clients per month
Problem: A niche where enterprise buyers ask an assistant for a shortlist before they ever contact a vendor. We mapped the prompts that mattered, placed Cydome in maritime security press and built the comparison content LLMs needed. Eleven months in: 4 new enterprise clients per month and the #1 position in ChatGPT for maritime cybersecurity.
Solution: Run a maritime cybersecurity query yourself right now.
426 new subscribers per month
Problem: A DTC brand in a category where models kept defaulting to the legacy players. We built the definitions, comparisons and citation architecture that gave LLMs a reason to recommend Hubble. Thirty-two months of compounding work: 426 new subscribers per month attributed to AI search channels, client-reported.
Solution: Type "best contact lens subscription" into Perplexity and check the sources listed on screen.

Whether you sell online or build a B2B pipeline, this list will tell you quickly if we're a good match.
Run a British ecommerce or DTC brand competing for "best …" and comparison prompts (see our approach to GEO for ecommerce).
Are a B2B SaaS company selling into Britain, where buyers shortlist vendors with chatbots (see GEO for SaaS).
Are a London fintech in a regulated market that needs models to get the facts right (see our fintech practice).
Are a multi-location business targeting "near me" and city searches.
Want an AEO agency UK partner that reports on citations and pipeline, and can commit to at least 90 days.
Don't have a website or a content foundation yet.
Expect overnight results, since citation authority usually takes 60-90 days to build.
Are shopping for the cheapest option.
Only care about Google rankings.
Every project is quoted after the audit. But so you can see roughly where you fit, here is how AEO services UK pricing usually breaks down.
$1,500–2,500/mo
Category isn't contested yet. One location, one city, a handful of buyer questions to win. Often the fastest results we get, simply because nobody in the category has started.
$3,000–4,500/mo
Several products or markets, competitors already visible in ChatGPT and Gemini. More prompts to contest, more content to rebuild, citations that have to be earned rather than claimed.
$5,000+/mo
Multi-market or multi-language, contested category. Scaled digital PR, reporting into your BI stack.
These figures come from what our current clients pay; we don't sell fixed packages. What you'd actually pay comes from the audit, and the audit is free.
It works towards one outcome: your business being named and cited when buyers ask an assistant for advice. That means finding your buyers' prompts, rewriting key pages into clear explanations, fixing schema and entity data, and earning mentions on British sites that language models trust, then tracking how often you appear.
SEO gets a page ranked. Answer engine optimisation gets your brand chosen as the reply in Google's Overviews, ChatGPT or Perplexity. GEO covers visibility inside longer generated responses, where the model compares several options. The three overlap, so we build on the rankings you already have instead of starting over.
Ask for proof you can check yourself: prompts to run in ChatGPT or Perplexity, with the results visible live. Then ask how they measure citations, which British sources they build mentions on, and whether their pricing is published. A vague reply to any of these is a warning sign.
AEO services UK pricing depends on how contested your category is and how many markets you cover. Local businesses usually invest $1,500-2,500 a month, established companies $3,000-4,500, and enterprise projects start at $5,000. The free audit shows which band fits.
Fixed packages assume every business needs the same amount of work, which is rarely true in generative search. Ranges show what to expect before a call; the audit sets the exact scope.
Yes. As a UK AEO agency for ecommerce, we focus on "best …" and comparison prompts, product and category schema, and the review sites assistants quote when shoppers ask what to buy. Hubble, a DTC contact lens brand, now gets 426 new subscribers a month from generative search channels.
ChatGPT, Gemini, Perplexity, Copilot, Claude and Google's generative results, including Overviews and AI Mode. Each picks sources differently: Google draws on its own index, Perplexity lists its sources openly, and ChatGPT search leans heavily on third-party pages and forum threads. An AI search marketing agency in the UK that treats them all the same misses those differences.
Yes, and many clients work this way. Your current team keeps rankings and campaigns, and we cover the generative layer. We share query data and content briefs, so both teams work from one plan and nobody duplicates effort.
Most clients see first citations within 60-90 days, sooner where competitors haven't started yet. Business results take longer: in our case studies, signups, sales calls and subscribers grew over 11 to 32 months. If a provider promises overnight wins, treat that as a red flag.
We track a fixed set of your buying prompts across the major platforms and record whether you're mentioned, cited or recommended, compared with local competitors. The monthly report shows citation frequency, share of voice and prompt-level changes. You also get the prompt list, so you can check any result yourself.
Each platform has its own logic for choosing sources, so this work performs best alongside platform-specific optimisation.
