Passion Digital
Passion Digital is a search-led performance marketing agency at Holborn Tower in London, founded in 2012 and acquired by Pixis.ai in 2025. Its AI search practice covers generative engine optimisation, AI Overviews optimisation, deep research, entity optimisation and LLM performance tracking.
The agency runs dedicated GEO, AI search and AI Overviews optimisation service pages, and uses proprietary tooling to monitor mentions, authority and sentiment across Google AI Overviews, ChatGPT, Gemini and Perplexity. It holds 33 verified Clutch reviews at 4.7.
Measuring and reporting your AI citation share matters as much as earning it.
- Multiple dedicated AI search service pages, not a single bolt-on page
- Proprietary tracking of mentions, authority and sentiment across four engines
- 33 verified Clutch reviews at 4.7, plus Google Premier Partner status
- Acquired by Pixis.ai in 2025, so no longer independent
- Paid media is an equally large part of the business, so AEO is not the whole offer
Omnius
Omnius is a remote-first B2B SaaS growth agency with bases in London, Belgrade and Dubai, serving SaaS, fintech and AI companies. It lists Answer Engine Optimization and Generative Engine Optimization as named services and says it is one of very few agencies that owns both the service delivery and the data-processing technology behind AI search optimization.
AEO and GEO are explicit service lines on its own site, and it operates a proprietary AI-search analytics product for LLM content scoring, source citation monitoring and zero-click query targeting.
You are a B2B SaaS or AI company that wants AEO delivered alongside its own visibility-tracking technology.
- AEO and GEO both named as standalone services on its own site
- Owns its in-house AI-search analytics tool
- States its work has been referenced by Y Combinator, Reuters and Bloomberg
- Positioned for SaaS, fintech and AI companies, so a poor fit for local or ecommerce brands
- Remote-first across three cities rather than a single London team
Found
Found is a London digital marketing agency established in 2005, based at the Johnson Building in Hatton Garden with a second office in New York and 90 or more marketing specialists. Its AI SEO service explicitly covers answer engine optimisation, generative engine optimisation, entity optimisation, voice search optimisation and LLM performance tracking.
Found's own AI SEO page names answer engine optimisation as a distinct deliverable alongside AI keyword and prompt strategy, and the agency is a Google Premier Partner with 100 or more awards and nominations.
You want answer-engine work delivered by an established, award-heavy agency that also runs your paid search.
- Names answer engine and generative engine optimisation as separate deliverables
- Established 2005 with 90 or more specialists and Google Premier Partner status
- London and New York offices for transatlantic clients
- Its Clutch profile shows no verified client reviews despite the agency's size
- AEO sits inside a broad, historically paid-search-led service mix
Iconic Digital
Iconic Digital is a London marketing agency with a head office on Adam Street, The Strand, and a network operations centre in Wallington, Surrey. Its Answer Engine Optimisation service covers intent-based content creation, FAQ schema implementation, entity optimisation and content layering, featured snippet targeting, and voice search and AI assistant readiness.
Iconic Digital runs a dedicated service page under the literal Answer Engine Optimisation label, one of the few London agencies to do so, with featured-snippet targeting and FAQ schema named as concrete deliverables, plus a free AEO audit offer.
Your priority is winning featured snippets, FAQ-rich results and voice answers rather than a broad AI-visibility programme.
- Explicit Answer Engine Optimisation service page with five named deliverables
- Central London head office on Adam Street, The Strand
- Offers a free AEO audit and strategy call as an entry point
- No pricing or project minimum is published
- No third-party rating profile on Clutch, G2 or GoodFirms was found during verification
Position Digital
Position Digital is a small London SEO and GEO agency founded in 2019, based at FOUNDRY on Forest Road in Walthamstow with a team of around nine specialists. It positions itself as an SEO and GEO agency for ambitious B2B firms and SaaS startups looking to boost visibility in Google, AI chatbots and everywhere search happens.
GEO audits, AI visibility tracking and AI brand auditing are named services on its own site, and the agency publishes its own GEO research and agency rankings rather than treating AI search as a bolt-on.
You are an early-stage B2B or SaaS company that wants senior, hands-on answer-engine work at a smaller scale.
- GEO audits and AI visibility tracking are named, distinct services
- Founded 2019 with a small senior team of about nine, so principals stay on the account
- Specialised in B2B and SaaS rather than general-purpose marketing
- Team of roughly nine limits capacity for enterprise-scale programmes
- No third-party rating profile on Clutch, G2 or GoodFirms was found during verification
Roar Digital
Roar Digital is a London full-service digital agency on Battersea Park Road with around eleven named staff. It sells generative engine optimisation as a dedicated service, describing it as ensuring a brand is cited, recommended and trusted across ChatGPT, Gemini and Perplexity.
GEO is a standalone service page covering content extractability, freshness discipline, third-party presence and entity optimisation, and the agency states a decade of experience across AI optimisation, SEO, paid media and CRM.
You want an evidence-led answer-engine engagement from a compact London team rather than a network agency.
- Dedicated GEO service page naming ChatGPT, Gemini and Perplexity as target platforms
- Verified London office address on Battersea Park Road
- States a decade of experience across AI optimisation, SEO, paid media and CRM
- Small team of around eleven named staff for enterprise-scale programmes
- Published case studies skew heavily toward property and estate-agency clients

Why work with a AEO agency in London
Terminology varies more in London than in the US. Some agencies label the work AEO, others GEO or AI SEO. What matters is whether the deliverables are named and concrete, which is how this list is ranked.
Several London agencies now run their own AI visibility tracking rather than reporting from a third-party tool, which is worth asking about before you sign.
Published minimums range from 1,000 dollars to 5,000 dollars per project. Several London agencies publish no pricing, which is noted on each card.
