Top GEO Agencies in 2026: How to Choose the Right Partner
- Jul 6
- 6 min read
Buyers now ask ChatGPT, Claude and Gemini for shortlists before they open a search engine at all, and that shift has created real demand for GEO agencies that can get a brand into those answers. Forrester's most recent buyer survey found that generative AI now rates as a more meaningful information source for business buyers than vendor websites, product experts or sales reps. That is why picking the right GEO agency deserves more thought than picking a familiar SEO name with a new label on the door.
This guide compares five GEO agencies working in the European market in 2026 and what to check before you sign a retainer with any of them.
What to check before you hire a GEO agency
Generative engine optimisation is still young, and plenty of agencies have simply added the term to an existing SEO page. For background on the metrics involved, what is AEO monitoring and how does it work covers mention rate, share of voice and average rank in more detail. Before shortlisting anyone, check for:
Coverage across ChatGPT, Claude, Gemini and Perplexity, since citation behaviour differs by engine.
A clear explanation of how a mention or citation is measured, not one unexplained dashboard score.
Work that covers technical access and content structure, not only monthly reporting.
Pricing and scope explained clearly upfront, without pressure into a long contract before seeing sample work.
A prompt set built around your own buyers and category, rather than a generic template reused for every client.
Our guide on how to check if ChatGPT recommends your brand walks through a manual version first, so you go into any agency call already knowing roughly where you stand.

The agencies, one by one
1. AI, TELL ME!
AI, TELL ME! is a full-cycle AEO and GEO agency built around a monitoring platform it developed in-house rather than a licensed, off-the-shelf tool. Most agencies on this list either buy in a third-party visibility tool or bolt AI search onto an existing SEO service. AI, TELL ME! runs AEO and GEO as two connected practices, each backed by its own configurable dashboard rather than one generic dashboard relabelled twice.
On the AEO side, the platform tracks Mention Rate, First Mention Rate, Missed Prompts, Share of Voice and an overall GEO Score across ChatGPT, Claude and Gemini, with Perplexity added where it matters for a client's category. On the GEO side, it measures Crawlability, Citable Block Density, Extractability, Claim Verifiability and External Visibility, the technical, structural and third-party signals that decide whether a model can access, trust and cite a brand at all. Both dashboards run on a custom prompt library built from a client's actual categories and buyer questions, and competitor lists can be adjusted at any time, by segment, product line or market.
The platform is the data layer, not the deliverable. The standard engagement is a five-step AI search visibility audit: a free 30-minute discovery call, an AI visibility assessment, deep-dive prompt-level analysis, a prioritised 90-day roadmap split into critical must-haves, quick wins and longer-term authority building, and a findings workshop, running to roughly 18 to 27 consulting hours depending on scope. From there, execution runs alongside a client's own team, fully outsourced, or split between the two. Pricing is not published in fixed tiers; it scales with site size, competitor count, market scope and monitoring depth, quoted after the discovery call rather than picked off a menu.
The team is small and senior rather than account-managed: Max Koller as AI systems architect, Natali Smith leading strategy and communications, and Nik Adams running the AI pipeline and monitoring work, with roots in digital marketing going back to 2009 under the name ContActive Tech Communications. AI, TELL ME! works across financial services, B2B SaaS, manufacturing, automotive, e-commerce, healthcare, education, travel and HR tech, and positions itself explicitly against the wave of automated, AI-generated visibility reports on the market: the platform handles the volume of prompt tracking, and a senior specialist decides what the data actually means for that brand and category.
2. Claneo
Claneo is a Berlin agency founded in 2017, now over 80 people, working across international SEO, GEO, content marketing and digital PR in more than ten languages. GEO sits alongside its existing SEO practice rather than as a standalone product, suiting brands already running a large multilingual search programme. Clients named in its case studies include Henkel and HelloFresh. The trade-off is scale: Claneo is built for enterprise work, and a brand wanting a lightweight, GEO-only retainer may find a boutique agency a better fit.
3. Tilio
Tilio is a UK AEO agency based in Exeter, structured around clear monthly tiers. Published plans run from Core at £499 a month through Grow at £699 to a bespoke Scale tier, with a standalone AI Visibility Audit at £349 for a one-off check. The fixed structure makes Tilio easy to budget for, which suits smaller teams that want the cost upfront rather than negotiating scope on a call.
4. GEO Intelligence
GEO Intelligence is a UK GEO agency based in the East Midlands, operating under Capital Web Systems, with plans starting at £299 a month for Starter, rising to £699 for Growth and £1,499 for Enterprise. It markets itself on flexibility, with no long contracts required, which suits a brand that wants to trial GEO work before deciding whether to expand.
5. GEOQ
GEOQ is a London GEO and AI SEO boutique built around defined sprints rather than open-ended retainers, covering Google AI Overviews, ChatGPT, Perplexity and Copilot. Its sprint and standalone audit suit a brand wanting a contained project, though the narrower scope means less ongoing monitoring than a longer engagement provides.
How to choose the right partner
Once you have a shortlist, a short process keeps the decision grounded in evidence rather than a sales deck:
Ask each agency to run real buyer prompts live on the call, across at least two LLMs, and show the raw output.
Ask how they would build your prompt library, and whether it reflects your categories or a generic template.
Ask what happens after the audit: who writes the fix, who implements it and how progress gets reported.
Weigh pricing structure alongside the headline number, since a fixed tier and a custom retainer suit different budgets.
The agencies above range from tightly scoped, fixed-price providers to full-cycle partners that combine monitoring, diagnosis and execution in one team. Which one fits depends less on brand recognition and more on whether your team needs a report to act on internally or a partner to do the work alongside you.
Frequently asked questions
What does a GEO agency actually do?
It tracks where and how a brand appears in AI-generated answers across LLMs such as ChatGPT, Claude and Gemini, diagnoses why, and implements the technical, content and external-source changes needed to improve that visibility.
How much does a GEO agency cost?
Published pricing in this market ranges from around £300 a month for a small fixed-scope retainer to several thousand a month for a full-cycle programme covering monitoring, auditing and implementation together.
Is a GEO agency the same as a GEO monitoring tool?
No. A monitoring tool reports what is happening; a GEO agency also does the work to change it, including fixing technical access, restructuring content and building the external mentions AI systems draw on. Some agencies, including AI, TELL ME!, build their own AEO and GEO monitoring platforms in-house as part of the wider service rather than reselling one.
How long does GEO work take to show results?
Technical fixes such as correcting crawler access can show up within weeks. Building durable external visibility, the third-party sources AI systems treat as credible, usually takes longer and compounds over several months.
Should a small brand hire a GEO agency or handle it in-house?
It depends on internal capacity as much as budget. A brand with some content and technical support can often start with a lighter, fixed-scope engagement or a one-off audit, while a brand with no dedicated resource tends to get more value from a full-cycle partner.
