Basic
Quirky Digital is a UK-based SEO agency that works with brands and ambitious SMEs to grow visibility online. Their approach focuses on improving SEO foundations first, then tailoring content and structure so AI search engines like ChatGPT and Perplexity are more likely to pick up and use it.
This positions them closer to an SEO agency evolving for AI search, rather than a highly specialised generative engine optimisation agency in the UK.
- Established SEO agency with a strong foundation in search marketing.
- GEO is integrated with traditional SEO audits and improvements through LSI keyword research.
- GEO doesn’t come off as their speciality; it’s tied to SEO services.
- Lack of independent GEO case studies.

- SMEs wanting GEO integrated into traditional SEO.
- Brands prioritising authority building and contextual relevance.
- Strong emphasis on SEO foundations before GEO, with a unique LSI keyword research approach.
So, how did we arrive at these scores? Definitely not randomly. They are based on the following criteria, which we’ll discuss in more detail at a later point:
- GEO expertise - Real capability as a GEO agency; not just rebranded SEO.
- Strategy - Can the agency think beyond execution? Strong GEO agencies should guide decisions, not just deliver tasks.
- Technical depth - Structured data, entities, and content built for AI retrieval. A true generative optimisation agency gets this right.
- Thought leadership - Do they actually understand GEO and prove it with insights, not fluff?
- UK market fit - Built for UK businesses, search behaviour, and real commercial use cases.
Why does finding the best GEO agency matter for your business?
In the past 18 months, tools like ChatGPT, Perplexity, and Google AI Overviews have started shaping how people discover brands right at the start.
A McKinsey survey shows 40-50% of consumers already use AI-powered search to make decisions in 2025. That’s a clear change in behaviour.
This is why choosing the best GEO agency matters for your business. The right agency helps your brand appear where decisions are actually made.
So, what changes for your business?
- Your brand needs to appear inside generated responses, not just search results.
- Generative engines prioritise brands they can reference confidently.
- Users often act on a single answer without browsing multiple sites.
- From ChatGPT to Copilot, visibility needs to be consistent everywhere.
- A strong GEO (+SEO) agency structures content for AI retrieval, not just ranking.
So, which agency is the best partner for your business size and growth goals? Let’s find out.

Buried’s evaluation framework - In detail
To create the above list, we scored agencies across five GEO-critical dimensions.
1. GEO expertise (Weight: 20%)
Does the agency demonstrate a dedicated GEO service, in-depth understanding of LLM behaviour, evidence-led methodology, multi-engine optimisation (ChatGPT, Perplexity, Copilot, Google), and experience in content architecture for AI retrieval? This is the most heavily weighted factor.
2. Strategic depth (Weight: 20%)
Does the agency provide strategic advisory, offer frameworks beyond basic optimisation, explain why and how GEO decisions work, and show clear thinking, not just tactics?
3. Technical maturity (Weight: 20%)
This includes schema/structured data sophistication, entity modelling, technical SEO + GEO synergy, AI readability adjustments, data cleanliness, and content formatting for LLM ingestion.
4. Thought leadership (Weight: 20%)
It’s measured through frequency of GEO publications, depth of insights, use of examples, transparency in methods, and quality of explanations. Agencies producing detailed, evidence-backed GEO content are ranked higher.
5. UK market relevance (Weight: 20%)
We prioritised agencies that actively support UK SMEs and mid-market companies, understand UK search behaviour, deliver geographic relevance, and publish UK-focused insights.
Understanding the ranking & scoring scale
Each agency is independently scored on:
- 5 = Industry-leading
- 4 = Strong
- 3 = Good but incomplete
- 2 = Weak/unclear
- 1 = Not demonstrated
How to choose the best GEO agency
Choosing the best GEO agency comes down to fit and capability. Here’s what to look for when comparing top GEO agencies and finding the right partner for your business.
Specialist vs full-service
Some agencies are built purely as a generative engine optimisation agency focused on LLM behaviour. Others offer GEO as part of a wider service mix.
- Specialist GEO agencies - Stronger depth in AI search, content structuring, and LLM behaviour.
- Full-service agencies - Better if you need SEO, PPC, PR, and GEO under one roof.
If AI visibility is a priority, a focused GEO agency usually brings deeper expertise. That said, GEO and SEO are closely linked. GEO builds on strong SEO foundations and doesn’t work well in isolation. Even if GEO is your main focus, choose an agency that integrates both.
Industry fit
Not all GEO agencies work the same way across industries. For example:
- Ecommerce brands need product-level optimisation
- B2B brands need authority and citations
- Local businesses need geographic relevance
Choose a GEO agency that understands how your customers search and how AI tools surface results in your sector.
Proof of AI visibility
Any good GEO agency should show real evidence, not just make big promises about visibility and citations. Look for mentions or citations in AI tools, case studies showing visibility growth, and examples of content appearing in AI answers. Without proof, it’s hard to judge if a GEO agency can deliver beyond theory.
Content vs technical balance
Strong GEO sits between content and technical SEO. Content needs to be structured for AI understanding; technical setup helps AI engines interpret and trust your site. The best GEO agencies balance both.
Common mistakes when choosing a GEO agency
Picking the wrong GEO agency can slow down your AI visibility before you even start. Here are common red flags to watch for:
No GEO case studies
If an agency claims to be a specialist generative engine optimisation agency but can’t show real examples, that’s a concern. Look for evidence of content appearing in AI answers, clear before-and-after visibility improvements, and proof beyond their own blog. No proof usually means limited real-world experience.
“AI SEO” confusion
Some agencies use terms like AI SEO, GEO, AEO, and LLM optimisation interchangeably throughout their website. A specialist GEO agency will use a single specific term, clearly define what they offer, explain how GEO differs from SEO, and show where AI visibility fits in their strategy. Lack of clarity often signals a rebranded SEO service, not true GEO expertise.
No clear methodology
The best GEO agency will explain how they approach content, structure, and tracking, not just promise results. Watch out for vague processes, no explanation of how the content gets cited, and no framework for measuring AI visibility.
Treating GEO as an add-on
Many GEO agencies bolt GEO onto existing SEO services without adapting their strategy for LLM behaviour. This often leads to generic content not suited for AI retrieval, missed opportunities for citations, and limited visibility across AI tools. The right agency builds for AI search from the ground up.
Over-promising quick results
AI search visibility takes time, testing, and iteration. Be cautious if a GEO agency promises instant visibility in AI tools, guaranteed placement in answers, or fast results without a clear process.
Why Buried is the number 1 GEO agency in the UK
Buried takes the top spot (with a 5-star Google rating) because we actually do GEO, not just talk about it.
Many UK agencies still treat AI search as a trend or an extension of SEO. We approach it differently. We’ve built our services around organic search, including both SEO and GEO from the ground up.
Our approach recognises that GEO differs from SEO in critical ways. GEO focuses on being cited and referenceable by generative engines (ChatGPT, Perplexity, Google AI Overviews, Copilot), not just ranking pages in traditional SERPs.
We also invest in creating clear, in-depth resources to explain how GEO works and how businesses can use it properly.
At Buried, we run integrated GEO & SEO strategies, maximising the return from an organic search optimisation work stream. Our approach is comprehensive. And we are perfectly positioned to help you, no matter which industry your business falls in or at what level you wish to get started.
Will TombsFounder, BuriedCase study of Pinter.co.uk/Pinter.com - GEO audit & ongoing SEO/GEO optimisation
Buried SEO and GEO experts analysed both the UK and US websites of Pinter, a home beer brewing product site with strong traditional SEO but weak generative engine visibility.
Despite ranking highly in Google UK for relevant keywords, the brand didn’t appear in AI search responses across 9 different prompts, highlighting a clear gap in GEO implementation.
As part of the GEO audit, Pinter scored 26/50 in GEO readiness, compared to our benchmark average of 31/50. While areas like speed (9/10) and rendering performed well (7/10), structured data scored 0/10, with additional gaps in content depth (5/10) and link-driven citations (6/10).
Buried identified that the product wasn’t strongly linked to its core category in training data. The proposed GEO strategy included targeted comparison content, educational articles, category alignment, third-party “best of” listings, and social/UGC (User-Generated Content) signals to strengthen how AI models associate the brand with its category.
While implementation is still ongoing, we’re already seeing clear improvements in Pinter’s AI search visibility, with Pinter outperforming competitors in Share of Voice.
FAQs
What is GEO?
GEO (Generative Engine Optimisation) improves how your brand appears in AI-generated answers. It focuses on making content easy for AI tools to understand, trust, and cite during responses.
How does GEO work?
GEO works by structuring content, entities, and data so AI tools can interpret and cite your brand. It combines content clarity, technical setup, and authority signals across platforms.
How much do GEO services cost in the UK?
GEO services vary by scope. GEO audits typically cost £2k-£10k. Ongoing retainers range from £3k-£8k monthly, depending on complexity, competition, and how advanced your AI visibility strategy needs to be.

Yes. GEO is becoming essential for every business in 2026. As AI search shapes discovery and decisions, brands need visibility in AI answers to stay competitive and relevant.
