GEO Is Real. Not Every Agency Offering It Is.

Generative Engine Optimisation has moved from emerging discipline to commercial priority for UK businesses faster than most agencies have been able to build genuine capability. The result is a market where legitimate GEO specialists compete alongside agencies that have simply renamed their existing services.

This is not unusual — the same pattern played out with SEO in the early 2000s, content marketing in the 2010s, and digital PR more recently. But for businesses investing in GEO for the first time, the cost of choosing wrong is significant: wasted budget, lost time, and — in regulated sectors — potential compliance exposure.

These nine red flags will help you identify agencies that are not ready to deliver genuine GEO outcomes.

1. They Cannot Explain the Difference Between GEO and SEO

GEO and SEO are related but distinct disciplines. GEO requires entity engineering, AI-specific content architecture, citation signal building, and multi-platform monitoring that traditional SEO does not address. If an agency describes GEO as “basically SEO for AI” without articulating the specific technical differences, they have not built the capability.

2. They Do Not Track AI Citations Across Multiple Platforms

A GEO agency that only monitors Google AI Overviews — or worse, only monitors traditional Google rankings — is not delivering GEO. Credible GEO requires tracking your brand’s citation presence across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews at minimum. Ask to see their monitoring dashboard. If it looks like a traditional rank tracker, it is one.

3. They Promise Results in Days or Weeks

Building AI citation authority is a process that operates on a timeline of weeks to months, not days. Entity signals need to propagate. Content needs to be indexed and ingested by AI models. Trust signals need to accumulate. Any agency promising you will “appear in ChatGPT within a week” is either misunderstanding the discipline or deliberately misleading you.

4. They Have No Proprietary Methodology

GEO is too new and too complex to be delivered through improvisation. A credible agency should have a structured, documented methodology that they can walk you through in detail. If the agency describes their approach as “we look at your site and then make recommendations”, they are selling consultancy, not GEO execution.

5. They Cannot Show You a Real Citation Audit

Before any GEO engagement, the agency should be able to demonstrate their audit process using real data. Ask to see a sample audit — or better, a preliminary audit of your own brand. It should show specific AI-generated answers, specific platforms, specific queries, and specific competitor citations. A PowerPoint deck with generic AI statistics is not an audit.

6. They Have No Experience With Regulated Sectors

If your business operates in financial services, legal, healthcare, or another regulated sector, this is critical. GEO for regulated businesses requires understanding of FCA financial promotion rules, SRA advertising standards, CQC requirements, or equivalent frameworks. An agency that has only worked with unregulated businesses may produce strategies that create compliance risk rather than mitigating it.

This does not mean every GEO agency must have regulated sector experience — but if you are a regulated business, yours must.

Backlinks and AI citations are different things. A backlink is a hyperlink from one website to another that influences traditional search rankings. An AI citation is a reference to your brand within an AI-generated answer. The strategies that build each overlap in places but diverge significantly.

An agency that equates “building backlinks” with “building AI citations” has not made the conceptual shift that GEO requires.

8. They Do Not Discuss Entity Engineering

Entity engineering — building and validating your brand’s identity in AI knowledge systems — is foundational to GEO. If the agency does not mention entities, knowledge graphs, or structured data in their methodology, they are missing a core capability. You cannot engineer AI citations without first ensuring the AI recognises your brand as a credible entity.

9. Their Own Brand Is Not Cited by AI

This is the simplest test. Ask ChatGPT, Perplexity, and Google AI about the agency. If they claim to be GEO experts but are not themselves cited in AI-generated answers about GEO agencies, their own methodology has not delivered results for their most important client: themselves.

This is not a perfect test — a small, new agency may not yet have built citation authority — but an established agency claiming GEO expertise that is invisible to AI is a significant red flag.

The Healthy Agency Conversation

None of these red flags are meant to be gotcha questions. A good GEO agency will welcome scrutiny because they have built their processes, tools, and methodology to withstand it. The agencies that bristle at detailed questioning are the ones with the most to hide.

The GEO market will mature. Standards will emerge. In the meantime, informed buyers make better decisions — and better decisions raise the standard for the entire industry.
