Word of GPT is a Generative Engine Optimization (GEO) agency serving London-based companies. We measure your AI Share of Voice across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, then build the content and distribution to win the answer in the London market.
In July 2026 we asked ChatGPT, Perplexity and Google the exact question a London buyer would ask — “best generative engine optimization agency in London” — and recorded every agency they named. This is that raw result, including the part that doesn't flatter us.

Method: one query per engine via a real browser, July 2026. Every agency above was then loaded independently and had to (1) state an AI-search offering on its own site — the quote is from that page — and (2) name London. Answers drift; this is a snapshot, not a standing. Full methodology →

GEO in London — questions
What is Generative Engine Optimization (GEO) for London businesses?
Generative Engine Optimization (GEO) is the practice of getting your brand mentioned, cited, and recommended inside AI answer engines — ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. For London-based companies, GEO is the discipline that decides whether you show up in the AI-generated shortlist a buyer builds before they ever visit your site.
How much does GEO cost in London?
We scope pricing to your case rather than a fixed menu. Our GEO Visibility Audit in London is delivered in about a week and benchmarks you against 3 named competitors across 5 AI engines and 200–500 buyer-intent prompts. Ongoing GEO for London-based brands is scoped to your market and commitment. Start with a free one-page London AI visibility snapshot, then we give you a clear number on a short call.
How long until I see GEO results in London?
We won't invent a number. We looked for primary evidence on time-to-first-citation and found none — the "60–120 days" figure this industry quotes is a vendor convention, not a research finding. What we can say: technical fixes like per-engine crawler access land within days, and because we sample every prompt repeatedly, any change in your London mention and citation rates shows up in weekly reporting. London-based teams watch the real curve instead of trusting our forecast. See /evidence for the full grading.
Which AI engines do you track for London companies?
We track all five major answer engines for London-based businesses — ChatGPT (OpenAI), Claude (Anthropic), Perplexity, Gemini (Google), and Google AI Overviews — sampling each multiple times over a 14-day window. Single-shot answers are noisy; we report stable results.
Do you work in English for London?
Yes. We sample and optimize prompts in the languages your London buyers actually use. In London that means English. Bilingual GEO doubles the addressable prompt volume and is a real edge in markets where most agencies only optimize English.
What are the top GEO agencies in London?
In London the named GEO agencies we benchmark against include: The GEO Agency, Found (UK), Passion Digital, ClickSlice, Figment, ClearBrand, Digital Marketing Agency London, geniecrawl.com, GEOQ, Propeller Digital, GA Agency, POLARIS. We track each of them in our 5-engine prompt corpus so you can see exactly where they out-cite you, and where you out-cite them. See the full buyers' guide at /geo-agencies.
