Should I hire a specialist AI search agency or add it to my existing SEO contract?

This is one of the most practical decisions UK businesses face when considering AI search optimisation. The answer depends on what your current SEO provider actually understands about how AI models select, interpret and recommend businesses. Choosing the right AI SEO agency requires understanding the fundamental differences between traditional search optimisation and AI search visibility.

Traditional SEO focuses on ranking positions within Google's organic results. AI search optimisation focuses on whether your business is included, accurately described and favourably positioned within AI-generated answers. These are related but distinct disciplines, and the skills required to execute them well do not always overlap.

The confusion arises because AI search optimisation is often presented as an extension of SEO. Many existing agencies have added "AI SEO" or "GEO" to their service pages without fundamentally changing their methodology. They may apply the same keyword-driven, content-volume approach that works for traditional rankings but does not address how AI models process and cite information.

AI models do not rank pages in a list. They synthesise answers from multiple sources, weigh authority signals differently from Google and evaluate content for clarity, specificity and consistency rather than keyword density or backlink volume. An agency that has genuinely adapted to this shift will talk about citation patterns, prompt behaviour, entity clarity and model confidence signals. An agency that has simply rebranded its SEO services will talk about keywords, traffic and rankings.

The distinction matters because ineffective AI search work can produce no measurable results, leaving you paying for a service that does not address the actual mechanisms behind AI visibility.

In some cases, an existing SEO provider genuinely does have the expertise to handle AI search work. This is more likely if the agency has invested in understanding how different AI platforms retrieve and process information, has experience auditing AI citation patterns and can demonstrate results in terms of AI inclusion rather than just Google rankings.

If your current agency proactively raised AI search as a topic, can explain the differences between ChatGPT, Perplexity, Gemini and Google AI Overviews in terms of how they source information, and has a clear methodology for improving AI visibility, they may be a credible option.

However, if your agency's response to AI search is to produce more blog content or add FAQ sections to your website, this suggests they are applying traditional SEO tactics without understanding the underlying AI mechanisms.

Ask your current agency specific questions:

- Can they show you how your business currently appears across ChatGPT, Perplexity and Gemini?

- Can they explain why your business is or is not being cited in AI answers?

- Do they understand the difference between a citation and a mention in AI responses?

- Can they audit your prompt visibility across multiple platforms?

- Do they have a methodology for improving how AI models interpret your business identity?

If the answers are vague, generic or redirect to traditional SEO metrics, this is a strong indicator that their AI search capability is limited.

A specialist AI search agency should be able to demonstrate a clear process for auditing AI visibility, diagnosing interpretation issues and building the signals that influence how AI models describe and recommend your business. They should also be transparent about what AI search can and cannot achieve.

If you have an existing SEO agency, start by having a direct conversation about AI search. Ask them what they are doing specifically for AI visibility and how they measure it. If their approach is essentially "keep doing good SEO and AI will follow", this is insufficient. Whilst traditional SEO provides a foundation, AI search requires additional work that many SEO agencies are not equipped to deliver.

If you are considering a specialist, evaluate them on the specificity of their methodology. Look for agencies that explain how AI models work, not just what they promise. Ask for examples of how they have improved a business's AI citation profile, not just its Google rankings.

It is also reasonable to run both in parallel. Some businesses maintain their existing SEO relationship for traditional search performance whilst engaging a specialist for AI search work. This avoids disrupting what is already working whilst addressing a gap that traditional SEO does not fill.

The most common misunderstanding is that AI search is simply "the next version of SEO" and that any competent SEO agency can handle it. Whilst there is overlap in foundational skills, the analytical framework, tools and methodology required for AI search are distinct. Assuming your current agency can manage it without verifying their specific capability is a risk.

Another misconception is that specialist AI search agencies are unnecessarily expensive or niche. In practice, the specificity of their focus often means they can identify and address visibility issues faster than a generalist agency that is learning as it goes.

Finally, some businesses assume they need to choose one or the other. In most cases, traditional SEO and AI search optimisation complement each other, and maintaining both is the most effective long-term approach.
