AI is changing how B2B software buyers discover and compare vendors.
G2’s 2026 research found that 51% of B2B software buyers now start their research with an AI chatbot more often than with Google, up from 29% eleven months earlier. The research, based on a March 2026 survey of 1,076 buyers, also found that 69% said chatbot guidance influenced which vendor they chose.
For SaaS companies, that creates a new visibility problem.
You can rank well in Google and still be missing from the AI answers your prospects see when they ask for software recommendations, alternatives, comparisons, or solutions to a specific problem.
That is the gap answer engine optimization, or AEO, is designed to address.
But not every agency approaches AEO in the same way. When comparing AEO agencies UK companies can work with, it is worth looking at how each one handles AI visibility, SEO, content, authority, and measurement.
Some build it into an existing SEO program. Others focus more heavily on digital PR and third-party citations. Some combine AI search with content and technical SEO, while others connect it with broader demand generation and revenue programs.
Pricing varies just as widely, and many agencies do not publish standard rates.
So this list focuses on the things a B2B SaaS buyer can actually compare. The right choice depends on your existing SEO setup, growth stage, budget, and whether you need AEO as a standalone service or as part of a wider B2B SaaS growth program.
10 AEO agencies UK B2B SaaS companies can consider
1. growth.cx
Best for: B2B SaaS scaleups that want AI search visibility connected to SEO, content, paid acquisition and outbound.
growth.cx approaches AEO as part of a broader growth program rather than as a standalone citation service.
Its Growth-Led AI SEO offering works alongside performance and ABM advertising, email and LinkedIn outreach, content, and website conversion work.
The idea is to connect these activities around the same ICP, buyer problems, and revenue goals instead of running AI search as a separate marketing project.
That makes the model particularly relevant for SaaS companies that have moved beyond basic SEO and want AI visibility to support a wider go-to-market strategy.
How the Strategy Performed
AIO Test
growth.cx helped AIO Tests improve its visibility across AI search through AEO, GEO, entity optimization, schema implementation, and content improvements. The program generated 435+ AI citations across 219 cited pages and achieved a 42% AI share of voice. The case study also reports an 84.95% increase in organic traffic.

HelloSend
For HelloSend, growth.cx integrated AEO and GEO into a broader SEO and content program covering technical SEO, content clustering, AI-focused content, and off-page optimization.
Over six months, the program generated a 314% increase in organic clicks, a 4,130% increase in impressions, and a 223% increase in organic traffic. Direct traffic also increased by 296%, while engagement rate improved from 52.5% to 56.6%.

Potential limitation
A company that only needs AI visibility tracking and citation optimization may not need a broader growth program.
Consider growth.cx if:
You want AEO to work alongside SEO, content, paid acquisition, and outbound rather than operating as a separate marketing channel.
2. Skale
Best for: B2B SaaS companies that want SaaS-focused SEO with AI citation work added to the program.
Skale is a London-based agency focused specifically on B2B SaaS.
Founded in 2019, it positions its SEO work around commercial outcomes rather than traffic alone, with reporting that includes signups, SQLs, and MRR.
Its AI Citation Outreach offering extends that SaaS SEO approach into AI search.
That combination can work well for SaaS companies that still see Google organic as an important acquisition channel but also want to understand how AI search is affecting vendor discovery.
Skale’s approach combines its existing SaaS SEO work with AI citation outreach.
The broader SEO program can include areas such as technical SEO, content and link building, while the AI component focuses on improving the chances of the brand appearing in relevant AI-generated answers.
Potential limitation
Skale’s SaaS specialization is useful if your company wants a focused SaaS SEO partner.
However, teams looking for a broader combination of AEO, paid acquisition, outbound, and demand generation may need additional support outside the agency.
Consider Skale if
You want a SaaS-focused SEO partner and see AEO as an extension of your existing organic growth program.
3. Integrated.Social
Best for: B2B teams looking to combine AEO with paid media and AI-led lead generation.
Integrated.Social positions itself as a B2B AI marketing agency covering AEO, GEO, AI search visibility, AI content operations, paid media, and agentic lead generation.
That broader scope is useful for teams that would rather manage fewer marketing partners.
The agency says AI Overview and Perplexity citations can begin appearing within four to eight weeks, with broader effects developing around the 90-day mark.
Those timelines are agency claims, so they should be treated as expectations rather than guarantees.
Its offering brings together AEO and GEO with areas such as:
- AI search visibility
- AI-assisted content
- Paid media
- Agentic lead generation
- Broader B2B marketing
That makes it less of a pure AEO specialist and more of a wider AI-focused marketing partner.
Potential limitation
The broad service offering can be useful, but AEO is one component of a wider marketing proposition.
Companies looking for a narrowly focused AEO partner may prefer a specialist agency.
Consider Integrated.Social if
You want AEO alongside paid media and AI-led lead generation from one London-based team.
4. Breaking B2B
Best for: B2B SaaS companies looking for a founder-led SEO and AEO program.
Breaking B2B is a UK-based, remote-first agency founded by Sam Dunning.
Its approach treats AEO as closely connected to good SEO.
The agency focuses on content formats that buyers and AI systems can use for evaluation, including alternatives pages, comparison pages, and best-of content. It also uses digital PR and third-party placements to build external authority.
That combination addresses an important part of AEO that can easily be overlooked: your own website is not the only source AI systems use when researching a company.
Its approach can include:
- B2B SaaS SEO
- AEO
- Comparison content
- Alternatives content
- Digital PR
- Third-party placements
- Revenue-focused reporting
Potential limitation
The agency operates with a relatively small team.
That does not necessarily indicate a delivery problem, but it makes account capacity worth discussing before signing. Ask who will work on the account and how much strategist and execution time is allocated each month.
Consider Breaking B2B if
You want a hands-on, founder-led B2B SEO and AEO partner and are comfortable with a longer engagement.
5. Position Digital
Best for: Smaller B2B teams that want GEO combined with digital PR.
Position Digital is a London-based agency founded in 2019.
Its AEO and GEO approach combines AI visibility measurement with technical SEO, citable content, and digital PR.
One of the more interesting aspects of its positioning is the connection between PR placements and AI visibility. Instead of treating earned coverage only as a branding activity, the agency looks at whether placements contribute to AI citations.
Position Digital focuses on:
- AI visibility measurement
- GEO
- Technical SEO
- Citable content
- Digital PR
- Brand authority
This makes it particularly relevant to companies that have already covered their basic technical SEO and need to build more external authority.
Potential limitation
Position Digital is a relatively small team.
The program can also depend heavily on the quality and relevance of digital PR placements. Ask what types of publications the team targets and how those placements relate to your actual buyer audience.
Consider Position Digital if
You want AEO combined with digital PR and are working with a smaller budget.
6. The SEO Works
Best for: Larger UK companies that want AEO within a broader SEO and digital marketing infrastructure.
The SEO Works is a long-established UK agency with offices in Sheffield and Leeds.
It works across SEO and digital marketing and has a considerably larger team than many specialist AEO agencies.
Its AEO approach includes what it describes as Universal Information Infrastructure, which focuses on making a brand’s information easier for search engines and AI systems to understand.
It also promotes LLM revenue attribution, connecting AI-driven visibility with analytics and CRM data.
The wider offering can include:
- Technical SEO
- Content
- AI search optimization
- Digital marketing
- Analytics
- AI and LLM attribution
For larger companies, that broader infrastructure can be useful when AEO needs to sit alongside an established organic search program.
Potential limitation
The SEO Works is a broad SEO agency rather than a SaaS-only AEO specialist.
That may be an advantage for larger companies with complex SEO requirements, but less relevant if you want a highly specialized SaaS AEO program.
Consider The SEO Works if
You want a larger UK team with established SEO infrastructure and AI search work as part of a wider organic program.
7. Omnius
Best for: SaaS and fintech companies looking for a selective SEO and AEO partner.
Omnius is a London-based agency founded in 2021.
It works with SaaS and fintech companies and covers AEO, technical SEO, content, programmatic SEO, and link building.
One differentiator is its AI visibility tracking technology, Atomic AGI.
The agency also describes itself as selective about new business, taking a limited number of new clients each year.
Its services include:
- AEO
- Technical SEO
- AI crawler optimization
- Programmatic SEO
- Content
- Link building
- AI visibility tracking
This makes it a fit for SaaS companies that want AEO incorporated into a more comprehensive organic search program.
Potential limitation
The selective client model can mean limited availability.
That may work well for companies looking for a smaller client roster, but it is worth asking about current capacity and expected onboarding time.
Consider Omnius if
You are a SaaS or fintech company looking for a specialist organic growth partner and are willing to work within a selective client model.
8. Blend
Best for: B2B companies using HubSpot that want AEO connected to their CRM.
Blend is based in Reading and also has a US presence.
The agency works heavily with B2B and professional services companies and is an Elite HubSpot Solutions Partner.
Its AEO offering covers areas such as AEO strategy, schema, entity optimization, and AI search visibility, alongside HubSpot integration and lead attribution.
The HubSpot connection is one of the main reasons a company might consider Blend.
If your marketing, sales, and reporting infrastructure already runs through HubSpot, connecting AI-driven acquisition signals to the CRM can be more useful than having an isolated visibility dashboard.
Blend’s AEO offering includes areas such as:
- AEO strategy
- Schema
- Entity optimization
- AI search visibility
- HubSpot integration
- Lead attribution
Potential limitation
Blend has a strong professional services and HubSpot orientation.
That may make it a good fit for a HubSpot-heavy B2B organization, but SaaS companies looking for a deeply specialized AI search partner may want to compare it with SaaS-focused agencies.
Consider Blend if
Your team is heavily invested in HubSpot and wants AEO connected to existing marketing and sales data.
9. LoudFace
Best for: SaaS companies that are not specifically looking for a UK agency and want transparent AEO measurement.
LoudFace was founded in Sweden and operates with a strong US-facing focus, so it is different from the UK agencies in this list.
Its offering combines SEO, AEO, GEO, content, and Webflow.
One of its main differentiators is transparency around AI search measurement and pricing.
The agency tracks buyer prompts and reports share of answers rather than relying only on raw citation counts.
LoudFace combines:
- SEO
- AEO
- GEO
- Content marketing
- Webflow
- Prompt tracking
- AI visibility measurement
That broader setup can be useful for SaaS companies that need both website and search work.
Potential limitation
LoudFace is not a UK agency.
It also publishes its own agency rankings, so buyers should examine the underlying evidence rather than relying on the ordering of those rankings.
Consider LoudFace if
You are not tied to a UK agency and want published pricing and prompt-level AI visibility reporting.
10. POLARIS
Best for: B2B companies that want AEO incorporated into a wider organic search and digital PR program.
POLARIS is a UK digital marketing agency serving B2B and eCommerce companies, from growth-stage businesses to larger enterprises.
Its AEO offering sits alongside technical SEO, content and digital PR rather than operating as a separate standalone service.
That can be useful if your website already needs significant technical and content work. Instead of creating a separate AEO project, your team can address traditional search visibility, authority, and AI search visibility within the same organic program.
The broader approach includes:
- Technical SEO
- Content
- Digital PR
- AEO
- Organic search
- AI search visibility
Potential limitation
POLARIS works across B2B and eCommerce, so it is not as narrowly focused on B2B SaaS as agencies such as Skale.
Consider POLARIS if
You want technical SEO, content, digital PR, and AEO handled as one broader organic growth program.
How to test an AEO agency before signing
A good sales presentation can make almost any AEO program sound impressive. A better way to compare agencies is to ask the same practical questions to each one.
1. Ask for the prompt set
Ask which buyer questions the agency plans to track.
A claim such as “your AI visibility increased by 40%” is difficult to assess without knowing what was measured.
2. Ask for the baseline
Find out where your brand appears before the work begins.
Ideally, you should know which prompts trigger your brand, where you appear, which competitors appear instead, and which sources AI systems cite.
3. Separate AEO from SEO results
An agency may have impressive organic growth case studies. That does not automatically mean those results came from AEO.
Ask which results came from traditional SEO, content, digital PR, AEO, or a combination of services.
4. Ask how attribution works
AI search attribution is still imperfect.
GA4 can identify some AI referral traffic, but not every AI-influenced buyer will click directly from an AI answer.
A simple “How did you hear about us?” field can therefore provide useful additional information.
5. Ask who will work on the account
A small team can deliver excellent work, but capacity matters.
Ask how many clients each strategist manages, who handles execution, and how much time the team expects to spend on your account.
6. Check the contract
If you are testing a relatively new channel, understand how easy it is to change scope or leave the engagement.
A 90-day test and a 12-month commitment are very different propositions.
You can also run a basic baseline yourself before speaking to an agency. Take 10 real buying questions, run them through several AI search platforms, and record which vendors and sources appear.
That gives you something concrete to discuss during the sales process.
How much do AEO services UK teams actually cost?
There is no standard AEO retainer.
A UK B2B SaaS company can encounter offers ranging from a few hundred pounds per month for measurement and audits to several thousand pounds per month for managed SEO, content, digital PR and AI visibility programs.
AEO pricing varies significantly depending on scope. A 2026 UK AEO pricing guide from MarGen puts monthly retainers at roughly £1,500 to £2,500 for entry-level work, £2,500 to £4,500 for foundation programmes, and £4,500 to £8,500 for more comprehensive authority programmes. Enterprise engagements can reach £8,500 to £18,000 or more per month.
Enterprise programs can cost substantially more.
The important point is that these are not necessarily comparable services.
A £350 monthly plan focused on measuring AI visibility is not equivalent to a £5,000 monthly program that includes content production, technical SEO, digital PR, and ongoing prompt tracking.
Before comparing prices, compare what you are actually getting.
What do AI SEO services UK typically include?
The scope can vary considerably between providers. Some focus mainly on AI visibility measurement, while broader programs may include content production, technical SEO, digital PR, link acquisition, and ongoing prompt tracking.
- Content volume: Creating and updating 20 detailed buyer pages every month requires more resources than maintaining five strategic pages.
- Off-site authority: Digital PR, review placements, and third-party content can involve substantial outreach and execution work.
- Measurement: Tracking a small set of prompts across two engines is different from monitoring hundreds of prompts across multiple AI search platforms.
- SEO scope: If the provider is also handling technical SEO, keyword research, content production, and link acquisition, you are buying a broader organic growth program rather than AEO alone.
Why growth.cx may be a fit for B2B SaaS scaleups
If you are comparing an AI SEO agency UK option with a specialist AEO partner, scope matters. growth.cx takes a connected approach to AI SEO, content, performance marketing, outbound, and website conversion.
This can suit B2B SaaS scaleups that want to build AI search visibility without treating it as a standalone channel. The exact mix depends on your existing marketing setup, growth stage, and goals.
Before starting an AEO engagement, growth.cx can help you assess:
- Which AI platforms and buyer prompts matter for your ICP
- Where your brand currently appears in AI search
- Which competitors and sources appear instead
- What content, SEO, or off-site gaps are limiting visibility
- How AI search activity can be connected to traffic, leads, and pipeline
The goal is to identify where your SaaS brand stands today and focus the work on the gaps that matter most to your growth goals.
What should you expect from an AEO agency?
Before signing, make sure the agency can clearly explain what it will measure, what it will change, and how progress will be reported.
A useful monthly report should show:
- Buyer prompts tracked: Which questions and searches are being monitored?
- AI platforms measured: Which engines or answer platforms are included?
- Brand visibility: How often does your company appear in relevant answers?
- Competitor visibility: Which competitors appear when your brand does not?
- Cited sources: Which websites and pages are influencing the answers?
- Progress from baseline: How has your visibility changed since the program started?
- Business impact: Can AI-referred traffic, leads, or AI-influenced opportunities be identified?
Don’t judge an AEO program by citation growth alone. Ask the agency to connect visibility changes to the buyer prompts, sources, traffic, and pipeline that matter to your business.
Want to see where your SaaS brand stands in AI search?
The right AEO agency depends on what your SaaS company needs today. A specialist may make sense if your priority is AI visibility tracking and citation growth. If your SEO, content, digital PR, and AI search efforts need to work together, a broader agency may be more suitable.
Before signing, ask how the agency measures AI visibility, which buyer prompts and AI platforms it tracks, what sources influence your visibility, and how AEO results are separated from traditional SEO results. Most importantly, make sure the scope matches your growth goals and budget.
If you want AEO to work alongside a broader B2B SaaS marketing strategy,growth.cx combines AI SEO and AEO with content, performance marketing, outbound, and conversion-focused work.

Frequently Asked Questions
2. What is the difference between an AEO agency and an AI SEO agency in the UK?
The main difference is scope. An AEO agency focuses on visibility in AI-generated answers and citations, while an AI SEO agency UK may cover those areas alongside technical SEO, content, authority building, and broader organic search.
3. How long do AEO services in the UK take to increase citations in AI-generated answers for a B2B SaaS company?
AEO services UK do not follow a fixed timeline. Some agencies report seeing initial citations within four to eight weeks, while broader AI visibility improvements may take around 90 days, depending on your content, authority, SEO foundation, and target platforms.
4. Why isn't my B2B SaaS brand showing up in ChatGPT, Perplexity, and Google AI Overviews, and can a UK AI SEO company fix it?
Your brand can miss AI answers even if it ranks well on Google. Gaps in content, third-party mentions, brand authority, or coverage of buyer questions can affect visibility. An AI SEO company UK can identify these gaps and address them through content, SEO, and authority work.
5. Can our existing SEO agency deliver AEO, or do we need a specialist AEO agency in the UK?
Your existing SEO agency can handle AEO if it already tracks AI visibility, buyer prompts, citations, and LLM-driven discovery. If its work is limited to traditional rankings and traffic, a specialist AEO agency may offer the additional expertise you need.
6. How much do AI SEO services cost in the UK for a B2B SaaS company, and what does each budget level include?
AI SEO services UK are usually priced based on the scope of work rather than a fixed package. Custom pricing can cover anything from AI visibility audits and content optimization to technical SEO, digital PR, authority building, and ongoing AI search tracking.
