5 UK AEO agencies compared for 2026

Updated 5 October 2026

For UK marketing teams that want specialist AI search support alongside their existing SEO work, Tilio is our recommended starting point. Our programme connects visibility tracking with website improvements, factual corrections and work on the external sources that AI answers cite.

How we compared agencies

Tilio publishes this guide and appears first. We reviewed each agency’s public service pages for its focus, delivery and reporting, with links beside the profiles. The recommendations reflect those published offers and our first-hand knowledge of Tilio’s work; we have not independently tested the other agencies’ delivery.

This is a selected shortlist of five agencies serving the UK. Our own AI visibility evidence appears separately below, with its dates and scope.

The quick comparison

Tilio

A strong fit for specialist measurement and implementation.

Tilio is an Exeter-based answer engine optimisation (AEO) and generative engine optimisation (GEO) agency. We work on whether your business appears in relevant AI answers, how it is described and which pages are cited. The starting point is the questions your buyers ask as they research a problem, compare providers and decide who to contact.

The work connects three areas:

• On your website: improve service pages, comparisons and supporting evidence; resolve technical barriers to reading the content; and make your offer easier to understand.
• Across external sources: examine relevant articles, directories and other pages cited in answers, then pursue useful additions or factual corrections where there is a credible reason to feature.
• Between research and delivery: check claims, prepare supporting material, agree priorities and approvals, assign the work and record what was published or changed.

For publisher outreach, that includes preparing a specific contribution, managing follow-ups and checking the live page. We then review subsequent AI answers. Our explanation of how we work with AI-cited sources shows that process in more detail.

This makes Tilio particularly relevant when you want a specialist team to connect the diagnosis with delivery. Agree the implementation and outreach included in your plan: a measurement-only engagement has a different scope.

Ask us: Which changes will you deliver, what will our team need to approve, and how will we see what happened afterwards?

Bubblegum Search

A strong fit for off-site reputation and outreach.

Bubblegum Search’s AI-search service combines prompt tracking, competitor and source research, and managed outreach. It focuses on earning relevant brand mentions in third-party articles, comparisons, reviews and roundups. It also offers white-label delivery for agencies.

That scope suits teams that already have website and SEO support and want help with external visibility. Website content creation, technical SEO and on-page optimisation are separately priced services, so include them explicitly if your brief needs them.

Ask: Which sources will you target, how will you assess their relevance, and what counts as a delivered mention?

Found

A strong fit for AI search within a wider marketing programme.

Found’s GEO service covers audits, content, technical implementation, source analysis and ongoing tracking through its Luminr platform. It offers this work as a focused project or within its broader search strategy.

Found is worth considering when AI visibility needs to sit alongside SEO, digital PR, paid media and other marketing activity. The practical question is how those teams will coordinate the work and distinguish AI-search progress in the reporting.

Ask: Who owns the AI-search plan, which changes are included, and how will the report separate visibility, citations and commercial outcomes?

Propeller

A strong fit for technical and content implementation.

Propeller’s GEO process moves from an audit into a plan for how the business and its services are represented, followed by technical changes, content development and measurement. Its scope also includes reviewing external listings, partner pages and profiles for inconsistent information.

Consider Propeller when the brief requires several connected website changes, including structured data: code that labels information such as your organisation and services. Its published process gives you a basis for discussing what the agency will implement and what needs your developers.

Ask: Which fixes will your team make directly, and how will you check whether the work improves relevant visibility?

Digital Landscope

A strong fit for combined SEO and AEO support.

Digital Landscope offers tailored monthly SEO and AEO engagements aimed at SMEs and in-house marketing teams. Its AEO offer includes question-led content, technical work and keeping information accurate for AI search.

That combination may suit a business that wants one plan for conventional search and AI answers. Compare the proposed allocation of work carefully, particularly if you already have someone responsible for SEO.

Ask: How will the plan divide work between SEO and AEO, which pages will you improve, and what will count as progress?

Tilio in AI answers

An agency’s own visibility gives you something practical to examine: does it appear when buyers ask about the services it sells, and how is it described?

Across all 54 questions in Tilio’s UK tracking from 5 September to 4 October 2026, Tilio ranked first by mention frequency among the brands in our tracking. Tilio appeared in 33.8% of answers, compared with 13.7% for Found. It led five of the eight verified topic groups below.

The question set covers research, comparison and buying decisions, and includes questions that name Tilio or other agencies. These results therefore describe our tracked set, including brand-specific questions; they are not an independent ranking of agency quality or a measure of unprompted recommendations.

Each topic groups related questions asked across the available AI engines. Tilio led on agency selection, reporting and competitor comparisons. It placed second on questions about getting cited in ChatGPT and third on questions about visibility in Google AI Overviews. These differences show where AI answers recognise the business more often.

Source: Tilio’s own Answyn tracking, UK, 5 September–4 October 2026. Overall analysis: 4,032 answers across all 54 tracked questions. The table shows eight verified topic groups. Available results came from ChatGPT, Google AI Overviews, Gemini, Google AI Mode and Claude; collection frequency and date coverage varied by engine. Rank compares how often brands were named, not their position within an answer. See how we measure AI visibility.

What those answers say

On 2 October 2026, ChatGPT answered “Which agency offers the most reliable AI search monitoring for B2B brands?” by describing Tilio’s “particularly transparent methodology”. It highlighted defined buyer questions, mention and citation tracking, and competitor monitoring.

On 17 September, ChatGPT’s answer to “Shortlist of GEO agencies that track competitor mentions across AI answer engines” linked to Tilio’s website and highlighted its question-by-question comparisons, cited-source analysis and access to the underlying answers.

These examples show Tilio being associated with transparent measurement and access to evidence. They also give you specific capabilities to examine in a proposal. Our visibility figures do not establish how much any individual website change or piece of outreach contributed.

What useful reporting shows

Ask each shortlisted agency to walk you through a sample report and one decision it would change. You should be able to see:

• The questions and coverage: what was asked, where, when and how often, with questions that name your brand identified separately.
• Mentions and citations: whether your business was named, whether a page was linked as a source, and which competitors appeared.
• Accuracy and context: whether the answer describes your services correctly and recommends you for a relevant need.
• The work and next step: what changed on your site or elsewhere, what subsequent answers showed, and the next action with an owner.

Track identifiable visits and enquiries alongside these measures where possible. A mention or citation alone does not establish a sale.

Choose the delivery you need

Give your shortlisted agencies the same brief: your priority services, market, buyer questions, competitors and existing team. Ask each to explain its first phase of work, what it will deliver itself and where it needs your input.

Compare fees against that scope. Check the number of questions and platforms monitored, content and development time, outreach, any publisher costs, reporting and contract terms. This makes proposals easier to compare than a single visibility score.

If you need that starting picture, Tilio’s AI Visibility Audit includes the underlying answers, competitor comparisons and a prioritised plan. You can use it to decide what work to commission next.

FAQ

What is the difference between AEO and GEO?

Answer engine optimisation focuses on how a business appears in answers. Generative engine optimisation focuses on visibility in generative AI systems. Agencies often use both terms for overlapping work, so compare the deliverables, platforms and measurement behind the label.

Do I still need SEO?

Yes. Google’s guidance on AI features says existing SEO best practices remain relevant to AI Overviews and AI Mode, with no special additional optimisation required. Your AEO agency should coordinate with whoever maintains your website, content and search performance.
