Modulus is a UK GEO agency (generative engine optimisation). AI engines answer UK business queries without sending a click — we make your brand the source they cite, through entity authority, structured data, and citation-ready content for the UK market.
Generative Engine Optimisation (GEO) is the practice of becoming a trusted, cited source inside ChatGPT, Perplexity, Gemini, Claude, and other AI search engines. When someone in the UK asks "best AI development studio" or "GEO agency UK," GEO ensures your brand is in the answer AI returns—not buried in page 9 of Google, but directly quoted in the AI's response. It works via structured data, entity authority, and citation-ready content that AI training pipelines recognise and cite.
| Signal | SEO | GEO |
|---|---|---|
| Goal | Rank on SERP | Be cited in AI response |
| Key signal | Backlinks, keywords, CTR | Schema, authority, Q&A |
| Audience | Google, Bing, Yahoo | ChatGPT, Perplexity, Gemini, Claude |
| Citation value | Indirect (via ranking) | Direct (named in answer) |
UK decision-makers increasingly start with ChatGPT, Perplexity, Gemini, and Claude to research vendors, software, and services. When an AI engine answers "best GEO agency UK" or "generative engine optimisation services," it cites only a handful of brands — and if yours is not cited, you are invisible to AI search, regardless of your Google ranking.
GEO is the discipline of becoming a cited source inside generative engines. Unlike SEO, which ranks your page on a results list, GEO gets your brand named and quoted directly in the AI's answer. The signals are different: AI engines prioritise structured data (Schema.org), documented expertise, and well-formatted Q&A content over backlinks and keyword density. A page ranked #1 on Google can be completely absent from ChatGPT's citations.
Most UK businesses have ranked for SEO but are invisible to AI Overviews, Perplexity, and ChatGPT. Competitors who ship citation-ready content and proper schema are already earning mentions. By the time your brand lands on the AI radar, the cite-share is already distributed.
As a GEO agency based in the UK, Modulus runs a monthly citation audit across 50+ UK-market buyer-intent queries (like "geo agency uk", "generative engine optimisation services uk", "geo ai uk") to track which AI engines cite your brand and competitors. We harden your Schema.org markup (Organisation, FAQPage, Speakable), architect citation-ready content that AI engines extract cleanly, and rebuild your entity authority so generative engines recognise your brand as a trusted source. You get a monthly report on citation rate by engine, share-of-voice vs. competitors, accuracy of AI's claims about your brand, and referral traffic attribution from AI sources.
GEO and SEO compound. Most UK clients pair our GEO services with our SEO packages because the same authority signals—cite-worthy content, clean structure, entity depth—lift both classic SERP rankings and AI citations. Many also layer LLM development to create proprietary AI agents that become citation sources themselves.

A GEO (Generative Engine Optimisation) agency helps brands become cited sources inside ChatGPT, Perplexity, Gemini, Claude, and other AI search engines. Unlike SEO agencies that optimise for Google rankings, GEO agencies optimise for direct citations in AI-generated answers. This is especially critical in the UK where buyers research via generative AI.
Generative Engine Optimisation is the practice of optimising your brand's structured data, content architecture and entity authority so that AI engines cite your brand as a trusted source when generating answers. It is the AI-search equivalent of SEO — but the optimisation signals are entirely different.
SEO optimises for ranked search-results pages on Google and Bing. GEO optimises for direct citations and answers inside ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. Most websites are invisible to generative engines even when they rank #1 on Google, because AI engines use different signals: Schema.org markup, entity authority, and citation-ready content matter far more than backlinks.
We track your brand citation rate across ChatGPT, Perplexity, Gemini and Claude on 50+ UK buyer-intent queries every month, plus referral traffic from AI engines, share of voice versus competitors, and pipeline attribution where possible. Monthly reporting shows citation trends, competitor gaps, and accuracy of what AI claims about your brand.
Modulus offers fixed monthly retainers for GEO services in the UK, billed in GBP or USD. Pricing depends on your industry, competitive landscape, and the breadth of queries tracked. Most retainers start after a complimentary citation audit that shows where your brand currently appears (or doesn't) in AI answers.
ChatGPT, Perplexity, Gemini, Claude, Microsoft Copilot, Google AI Overviews, Bing Copilot and Meta AI. The same content architecture and schema markup works across all major generative engines, so you don't need to optimise separately for each one.
GEO works best with localised buyer-intent signals and market context. Modulus delivers regional GEO services tailored to each market's AI search behaviour, competitive landscape, and language nuances.
