Finding the best Answer Engine optimisation (AEO) agency in the UK sounds simple, until you actually start looking. Almost every agency talks about AI search, visibility and results, so how do you know which ones can genuinely deliver?
That is exactly what we wanted to find out.
We researched and shortlisted 7 of the best AEO agencies in the UK for 2026, and we looked beyond what they say about themselves. We compared their AEO and Generative Engine Optimisation (GEO) services, client portfolios, case studies, measurable results, reviews on Clutch, Google and Yell, pricing transparency, AI search capabilities and technical SEO support.
But there was one more question we kept coming back to: who is each agency actually right for? Because a startup looking for affordable AEO and SEO support does not need the same agency as an enterprise managing thousands of pages.
So, rather than giving you a list where every agency somehow sounds like “the best,” this guide tells you where each one genuinely stands out, what you should know before choosing it and, most importantly, whether it makes sense for your business.
Best AEO Agencies in the UK: Quick Comparison
Here’s a quick look at how the top AEO agencies in the UK compare.
| Agency | Location | Best for | Starting Investment |
| YellowInk Digital | Pinchbeck, England | Startups and SMEs wanting AEO, GEO and SEO together | From £370/month* |
| Tilio | Exeter, England | Startups wanting dedicated AEO/GEO and AI visibility tracking | From £499/month |
| The SEO Works | Sheffield, England | Growing SMEs that already have an SEO foundation | From approx. £740/project* |
| 21 Degrees Digital | Leeds, England | Growing businesses wanting GEO alongside wider digital marketing | From £1,600/month |
| Rogue Logic | UK | Startups and SMEs wanting focused AEO and measurable AI visibility | From £1,500/month |
| AxiomAI | Scotland, UK | Businesses wanting an AI-search-first AEO and GEO strategy | Custom quote |
| Blue Array | Reading & London, England | Growing businesses wanting specialist GEO and organic search support | From approx. £740/project* |
Just a quick note on pricing: YellowInk’s figure is an approximate GBP equivalent of the SEO package currently listed on Clutch, while The SEO Works and Blue Array figures are based on their current minimum project sizes on Clutch. These numbers are useful as a starting point, but they shouldn’t be treated as official AEO package prices, as the final cost will depend on the scope and requirements of your project.
How We Selected the Best AEO Agencies for Startups and Small Businesses
We were not looking for the biggest agencies. We wanted to know which ones actually make sense for a startup, where budget, flexibility and access to the right team matter.
Here is what we looked at:
- AEO and GEO Services: We checked whether agencies genuinely offer AEO or GEO, including content optimisation, schema, technical SEO, AI visibility tracking and digital PR.
- Startup and SME Suitability: Could a startup realistically work with them? We looked at pricing, flexibility and whether they actually serve startups and SMEs.
- Case Studies and Results: We looked beyond “results-driven” claims and checked for real results, including traffic, rankings, leads and AI citations.
- Independent Reviews: We also checked Clutch, Google and Yell reviews wherever reliable feedback was available.
- Pricing: Where prices were public, we included them. Clutch minimum project sizes were treated only as a rough guide, not official AEO pricing.
- AI Visibility Measurement: Finally, we looked at whether agencies track AI citations, brand mentions, referral traffic and conversions, so you can actually tell if the work is paying off.
Now, let’s get to the agencies.
7 Best AEO Agencies for Startups and Small Businesses in the UK
So, which agencies are actually worth considering? Here are the top AEO agencies in the UK for 2026 and what each one does best.
1. YellowInk Digital
Location: Spalding, England
Best for: Startups and SMEs wanting SEO, AEO and GEO together
Starting investment: From approximately £370/month*
YellowInk Digital takes the top spot on our list, especially if you are a startup or small business. Why? Because at that stage, you probably do not need AEO alone. You may need better Google rankings, stronger website content, more traffic and, increasingly, visibility on AI search engines like ChatGPT, Perplexity, Claude, Gemini, Copilot, etc.
Instead of handling these as separate problems, YellowInk works on them together.
Core Services
Its core AEO services include:
- Question and Intent Research: Identifying the informational, comparison and decision-based questions potential customers are actually asking.
- Answer-Focused Content Optimisation: Improving existing pages or creating new content that gives clear and useful answers without adding unnecessary information.
- Structured Content and Formatting: Organising pages with logical headings, sections and formatting so answer engines can understand and extract relevant information more easily.
- Schema and Data Markup: Using structured signals to help answer engines better interpret the information and context on a website.
- Entity and Topic Clarity: Making it clearer who the business is, what it offers and which topics it should be associated with.
- Ongoing Performance Review: Tracking how content appears across search features and AI tools, then refining the strategy as search behaviour changes.
What makes this useful for startups is that YellowInk does not treat AEO as simply adding FAQs to a website. It works on the questions people ask, the answers they find, how those answers are structured and whether search and AI platforms can clearly understand the business behind them.
Results and Reviews
Now, this is where we looked beyond the services listed on the website.
YellowInk has a 5-star rating with 24 and 18 reviews on Clutch and Yell, respectively. Clients have reported improvements in Google rankings, organic traffic, leads and revenue.
The agency also shares some useful numbers in its case studies. One automotive client saw a 3.1x increase in organic and local traffic, while a cleaning business saw bookings increase by 2.9x.
Why YellowInk Stands Out in Our List
What we like here is that YellowInk does not expect a growing business to have everything else figured out before starting AEO.
If your SEO still needs work, they can work on that. If your website design or content needs improvement, that can be addressed too. And if you want your brand to become more visible on ChatGPT and other AI platforms, AEO and GEO can be built into the same strategy.
For a startup or SME trying to improve Google visibility and AI visibility together, that makes YellowInk a great option on a budget.
Best Suited For
- Startups and small businesses
- SMEs building organic visibility
- Local businesses needing SEO and AEO together
- Companies that also need human -written content and website design or development support
Things to Consider
One thing to keep in mind is the pricing. The starting figure we have mentioned comes from YellowInk’s SEO package listed on Clutch, converted approximately into pounds. So, this is not YellowInk’s official AEO package price, and your actual cost will depend on what your business needs.
Also, while YellowInk makes sense for startups and SMEs that need SEO and AEO together, a large enterprise looking only for advanced, enterprise-scale GEO support may be better suited to a specialist provider.

2. Tilio
Location: Exeter, England
Best for: Startups wanting dedicated AEO/GEO and AI visibility tracking
Starting investment: From £499/month
Tilio is a more specialised option on this list. Unlike YellowInk, which brings SEO, AEO, content and other digital marketing services together, Tilio has a much narrower focus: understanding how brands appear in AI-generated answers.
That can be useful if you already have your SEO and content foundations in place and mainly want to understand your visibility on platforms like ChatGPT.
Core Services
Tilio focuses on AEO, GEO, AI search analytics, content optimisation, fact-checking and third-party authority building. It tracks brand visibility across ChatGPT, Claude, Google AI Overviews and Perplexity.
The service range is more focused than a full digital marketing agency, so businesses needing SEO, website development, PPC or broader marketing support may need other providers alongside it.
AEO and GEO Approach
Tilio starts by looking at how AI platforms currently describe, mention and recommend your brand. Its higher service levels then add content optimisation, technical work, fact-checking and third-party mentions.
It is a sensible approach if you already know what you want from AEO. For a younger business that still needs help with SEO, content and its overall search presence, however, the narrower focus may feel limiting.
Results and Reviews
Tilio is transparent about its pricing, which makes it easier to understand what you are paying for. Its Baseline plan starts at £499 per month, but this is mainly focused on AI visibility tracking and analysis.
Businesses that want actual content work and implementation will need to move to the higher Momentum level.
Why It Stands Out
Tilio stands out for its focused AI visibility tracking. If you already have an SEO team or agency and simply want to know how your brand is performing across AI platforms, it can be a useful addition.
For businesses looking for SEO and AEO under one roof, though, a broader agency may make more sense.
Best For
- Businesses that already have SEO support
- Teams wanting to measure AI search visibility
- Brands specifically exploring AEO and GEO
- Companies that value transparent pricing
Things to Consider
The biggest thing to understand is that £499 per month does not get you a complete managed AEO campaign. The Baseline plan is primarily focused on analytics and visibility tracking. Content and hands-on implementation come with higher service levels.
So, while Tilio is an interesting specialist option, it may not be the most practical choice for a startup that still needs SEO, content and broader digital marketing support alongside AEO.
3. The SEO Works
Location: Sheffield, England
Best for: Growing SMEs with an existing SEO foundation
Starting investment: From approximately £740/project*
The SEO Works is a better fit for startups and SMEs that already have the basics in place. If SEO is already bringing some visibility and you now want your business to appear in AI-generated answers too, this agency is worth considering.
Core Services
The SEO Works offers SEO, AEO, AI search, technical SEO, content, digital PR, PPC and web services.
AEO and GEO Approach
Its AEO service focuses on helping platforms like Google AI Overviews, ChatGPT and Microsoft Copilot better understand and use your content. It combines clear, answer-focused content with technical SEO, schema and the SEO work you already have in place.
Results and Reviews
The SEO Works has a strong review profile, with a 4.8/5 rating from 58 reviews on Clutch. Clients often mention improvements in organic traffic, keyword rankings and overall search visibility.
Why It Stands Out
What makes The SEO Works interesting is its SEO experience. Instead of treating AEO as something completely new, it builds AI visibility on top of traditional SEO. This makes sense for businesses already investing in organic search.
Best For
- Growing SMEs
- Established startups
- Businesses already investing in SEO
- Companies wanting SEO and AEO together
Things to Consider
The SEO Works may be more than a very early-stage startup needs. Its SEO packages on Clutch also start above the listed minimum project size, so it is better to ask for a specific AEO quote rather than using that minimum figure as the expected campaign cost.
4. 21 Degrees Digital
Location: Leeds, England
Best for: Growing businesses wanting GEO alongside wider digital marketing
Starting investment: From £1,600/month
21 Degrees Digital is worth looking at if your business has already moved past basic SEO and now wants to be more visible in AI search. The focus here is not just on ranking higher. It is also about getting your brand mentioned, cited and recommended in AI-generated answers.
Core Services
The agency offers GEO, AEO, AI visibility tracking, schema, content, technical optimisation and digital PR, along with its wider digital marketing services.
AEO and GEO Approach
It starts by checking how visible your brand already is across AI platforms. From there, the team works on technical improvements, answer-focused content, digital PR and citations. It also tracks things like AI mentions, citations, share of voice and enquiries.
Results and Reviews
According to 21 Degrees, more than 150 client brands have appeared in AI answers. Its website also includes a client testimonial mentioning leads coming directly from ChatGPT. However, these results are shared by the agency itself rather than independently verified through Clutch.
Why It Stands Out
What makes 21 Degrees interesting is that it combines GEO with technical SEO, content and digital PR. So, you are getting more than just a few AI-focused content changes.
Best For
- Growing startups
- SMEs with larger marketing budgets
- Businesses wanting GEO and digital PR together
- Companies wanting to track AI visibility
Things to Consider
The main thing to think about is the price. Plans start at £1,600 per month, which may be too much for a bootstrapped startup. The agency also positions its services towards more established businesses, so it makes more sense once you have the budget and marketing foundations in place.
5. Rogue Logic
Location: Bristol, England
Best for: B2B startups and SMEs wanting senior-led AEO support
Starting investment: From £1,500/month
Rogue Logic is a smaller agency, and that is actually part of its appeal. Instead of dealing with several account managers, clients work more directly with the senior people handling the strategy and execution. For a founder or smaller business, that can make communication much easier.
Core Services
Rogue Logic offers SEO, AEO, digital PR, paid search and marketing automation. Its AI search work covers platforms such as ChatGPT, Claude, Perplexity, Gemini and Google’s AI search experiences.
AEO and GEO Approach
The agency goes beyond simply changing content for AI. It works on structured data, entity signals, brand consistency, authority and third-party sources that can help AI platforms better understand and trust a business.
Results and Reviews
Rogue Logic is still relatively new, so you will not find the same number of independent reviews as you would for a more established agency like The SEO Works. On the positive side, its pricing is clear, with services starting at £1,500 per month.
Why It Stands Out
The main attraction is direct access to senior specialists. If you run a smaller B2B company and prefer working closely with the people actually doing the work, Rogue Logic could be a good fit.
Best For
- B2B startups
- SMEs
- Founder-led businesses
- Companies wanting senior involvement
- Businesses needing SEO and AEO together
Things to Consider
The main drawback is its shorter track record. There is less independent review history to judge it by, and at £1,500 per month, it may also be too expensive for a very early-stage startup.
6. AxiomAI
Location: Scotland, UK
Best for: Businesses wanting an AI-search-first AEO and GEO strategy
Starting investment: Custom quote
AxiomAI is worth looking at if AI search is already an important part of your marketing plan. It is not simply a traditional SEO agency that has recently added AEO. AI search appears to be a much bigger part of what it does.
Core Services
AxiomAI offers SEO, GEO/AEO, AI search optimisation, PPC, AI automation and email marketing. So, while AI is a major focus, businesses can still get SEO and other marketing support from the same team.
AEO and GEO Approach
What we like here is that AxiomAI does not treat every AI platform the same. Your business might appear in Google AI Overviews but still be missing from ChatGPT or Perplexity.
So, it looks at the questions people are asking and tracks where your brand appears across different AI platforms.
Results and Reviews
AxiomAI also focuses on business results such as qualified enquiries, cost per qualified lead and lead-to-opportunity rates.
However, there is less independent review and case-study evidence available than for some of the more established agencies on this list. That makes its track record slightly harder to judge.
Why It Stands Out
If you want your business to appear across different AI platforms, AxiomAI is worth considering. Its approach feels more AI-first than traditional SEO-first.
Best For
- AI-focused startups
- Scottish businesses
- Companies targeting several AI platforms
- Businesses wanting SEO and GEO together
Things to Consider
We would ask a few questions before signing up. AxiomAI does not publish a clear AEO starting price, so you will need a custom quote. We would also ask for relevant case studies and exactly how the agency plans to measure improvements in your AI visibility.
7. Blue Array
Location: Reading and London, England
Best for: Growing businesses wanting specialist organic search and GEO support
Starting investment: From approximately £740/project*
Blue Array is a little different from some of the other agencies on this list because search is what it mainly does. We would look at it if you already have a marketing team and now want specialists to take your SEO and AI search visibility further.
Core Services
Blue Array focuses on SEO, GEO, technical SEO, content and digital PR. It also works on areas like international SEO.
AEO and GEO Approach
The idea behind its GEO service is simple: help your brand appear and get cited in AI-generated answers on platforms like ChatGPT and Gemini. But it does not forget traditional SEO. The team also works on making your content easier for search engines and AI platforms to find and understand.
Results and Reviews
Blue Array has a 5.0/5 rating on Clutch, but there are only two verified reviews, so we would keep that in mind. One long-term client reported a 21% increase in sales and a 100% increase in visitor traffic. These results, however, came from its wider SEO work rather than GEO alone.
Why It Stands Out
What we like about Blue Array is its clear focus on search. If you already have the rest of your marketing covered and simply want stronger SEO and GEO expertise, it could be a good fit.
Best For
- Scaleups
- Growing SMEs
- Businesses with their own marketing teams
- Companies focused on SEO and GEO
Things to Consider
Pricing is something we would check before making a decision. Clutch’s minimum project size should not be taken as the cost of a full GEO campaign. Also, if you are an early-stage startup that needs help with several areas of marketing, a broader agency may make more sense.
How to Choose the Right AEO Agency
So, how do you actually choose one? We would start by looking past the word “AEO” on an agency’s website. Check what they actually do with AI search, technical SEO, content, structured data and citation tracking. More importantly, look for case studies and results that back it up.
Read More: How to Choose the Right Digital Marketing Agency
Then think about what your business actually needs. Do you want AEO alone, or do you still need SEO, content and technical support too?
Before signing anything, we would also ask which AI platforms they track, what they will actually deliver, how often they report and what is included in the price. You should know exactly what you are paying for.
Our Final Verdict
So, which one would we choose? For startups and SMEs, YellowInk Digital takes our top spot. The main reason is simple: most growing businesses do not need AEO alone. They usually need SEO, better content and stronger overall visibility too, and YellowInk brings these together.
That does not mean it will be right for everyone. Larger businesses may prefer a more specialised enterprise agency, while others may only need AI visibility tracking.
Our advice? Choose the agency that fits where your business is right now. But if you want SEO and AEO to grow together without juggling different agencies, YellowInk is where we would start.
