The GEO Agency Market Is Growing. So Is the Risk of Hiring the Wrong One.

Generative Engine Optimisation is one of the fastest-growing disciplines in UK digital marketing. That growth has attracted genuine specialists — and a significant number of agencies that have relabelled existing SEO or PR services as “GEO” without building the capabilities the discipline actually requires.

For UK businesses evaluating GEO agencies, the stakes are real. A poorly chosen agency wastes budget, delays your AI visibility programme by months, and — in regulated sectors — can create compliance risks that take far longer to unwind than the original engagement.

These twelve questions will separate the agencies that can deliver from the ones that cannot. Ask every one of them before you sign.

The 12 Questions

1. What specific AI platforms do you track and optimise for?

A credible GEO agency should name specific platforms: ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini, at minimum. If the answer is vague — “all the major AI platforms” — without specifics, the agency may not have built platform-specific monitoring capability.

2. Can you show me a current AI citation audit for a brand similar to mine?

Any agency claiming GEO expertise should be able to demonstrate a real audit — not a templated deck, but a genuine analysis showing where a brand appears and does not appear in AI-generated answers. Ask to see the methodology, the platforms covered, and the specific queries tested.

3. How do you distinguish between GEO and traditional SEO in your methodology?

GEO requires entity engineering, structured data optimisation, citation signal building, and AI-specific content architecture. If the agency describes GEO as “SEO but for AI” without explaining the distinct technical capabilities, they are likely repackaging existing services.

4. What is your approach to entity engineering?

Entity engineering — building your brand’s recognisable identity in AI knowledge graphs — is foundational to GEO. Ask how the agency builds and validates entity signals across directories, structured data, and authoritative sources. If entity engineering is not a core capability, the agency is missing a critical piece.

5. How do you handle regulated sector requirements?

For FCA-regulated financial services, SRA-regulated legal practices, and CQC-registered healthcare providers, GEO strategies must operate within specific compliance frameworks. Ask how the agency navigates advertising standards, financial promotion rules, or medical advertising guidelines. Generic answers here are disqualifying for regulated businesses.

6. What does your reporting look like, and what metrics do you track?

GEO reporting should include citation frequency across platforms, citation accuracy, competitive citation analysis, prompt cluster coverage, and — ideally — downstream commercial impact. If the agency reports primarily on traditional SEO metrics (rankings, organic traffic, backlinks), their measurement framework has not caught up with the discipline.

7. How long before we see measurable results?

Honest GEO agencies will tell you that citation authority builds over weeks and months, not days. Initial audit and strategy phases typically take 4-6 weeks. Measurable citation improvements often begin within 60-90 days. Any agency promising immediate AI visibility results is either overpromising or conflating GEO with something else entirely.

8. Do you have a proprietary methodology or framework?

A GEO agency that has invested in developing a structured, repeatable methodology — not just a collection of tactics — demonstrates deeper capability. Ask them to walk you through their framework step by step. You should be able to understand the logic even if you are not a practitioner.

9. How do you handle competitive displacement?

A significant part of GEO is displacing competitors who currently appear in AI answers for your target queries. Ask how the agency identifies competitor citations, analyses why competitors are being cited, and builds the signals to displace them. If competitive displacement is not part of the methodology, the agency is playing defence only.

10. What is your content production approach for GEO?

AI models cite content that demonstrates genuine expertise — not marketing copy. Ask whether the agency produces content in-house, uses your subject matter experts, or relies on generic content writers. The quality and specificity of content production directly determines citation outcomes.

11. Can you provide UK-based client references?

Ask for references from UK businesses, ideally in your sector or a similar one. GEO in the UK market has different dynamics than in the US — regulatory environment, directory ecosystem, media landscape, and buyer behaviour all differ. US-focused case studies may not translate.

12. How do you price your services, and what is included?

GEO agency pricing models vary — retainer, project-based, performance-linked, or hybrid. Understand exactly what is included: audit, strategy, content production, entity engineering, citation monitoring, reporting. Beware agencies that quote low retainers but charge separately for every deliverable.
