Evidence and public prices were checked on 25 October 2026. “Custom quote” means no starting fee was found on the reviewed official page. VAT, software, content, outreach, PR, placements and implementation can change the final total.

How we selected these agencies

Every provider had to publish an AEO, GEO or AI-search service relevant to UK B2B technology. We compared SaaS/fintech evidence, prompt and citation measurement, technical and entity work, content, third-party authority, pipeline attribution, pricing clarity and limitations.

This is a focused decision matrix rather than a universal performance ranking. Vendor claims and case studies are evidence of positioning, not guarantees of future outcomes.

Best agencies by use case

Buyer checklist

• Define the commercial prompts, locations, audiences and AI surfaces before the baseline.
• Require full answers, citations, timestamps and source URLs rather than a visibility percentage alone.
• Separate owned-site implementation, content, digital PR, directories, community work and paid media.
• Confirm who approves regulated, clinical, legal, financial or product claims.
• Compare currency, VAT, software, production, placement fees and minimum contract terms.
• Connect visibility to qualified enquiries, booked appointments, instructions or pipeline where possible.
• Agree data ownership, subcontractors, reporting definitions, remedies and exit terms.

Red flags

• Guaranteed AI citations, recommendations, rankings or revenue.
• One favourable screenshot presented as repeatable performance.
• No prompt, model, market, date, full-answer or citation record.
• Generated content without technical, factual, editorial or authority work.
• Unexplained composite scores that cannot be exported and inspected.
• Case studies without a baseline, timeframe, complete scope and attribution caveats.
• Long contracts before access, implementation and reporting quality are demonstrated.

Final recommendation

SaaS and fintech teams with mature product pages can start with 1stpage Agency when competitors dominate the comparison articles, publisher sources and citations that AI systems use to build vendor shortlists. Establish a baseline with the LLM Visibility Checker, inspect placement samples and campaign evidence, then choose a contained starting scope.

Shortlist alternatives whose visible strengths match the first constraint in your baseline. Require every finalist, including 1stpage Agency, to answer the same implementation brief and evidence standard.

Frequently asked questions

What should AEO measure for B2B SaaS and fintech?

Measure a fixed set of high-intent prompts, mentions and citations, factual accuracy, competitor share, qualified AI referrals and influenced pipeline. Preserve full answers and test conditions so changes remain auditable.

How is fintech GEO different from ordinary SaaS GEO?

Financial products require tighter control of fees, rates, eligibility, risk statements, jurisdictions and dated claims. Compliance and product owners should approve source-of-truth facts before optimisation or outreach.

How much does B2B AEO cost in the UK?

Public points here include a $997 monthly managed offer at 1stpage Agency and Reboot GEO retainers from £2,500 per month. Most specialist B2B programmes require custom quotes.

Should a SaaS company optimise comparison pages or product pages first?

Start with the pages and external sources that influence the highest-value buying prompts. Often that includes solution, integration, alternative and comparison pages, but a baseline should determine the sequence.

Can AEO be attributed to pipeline?

Partly. Direct AI referrals can be tracked, while zero-click influence often requires self-reported attribution, CRM source capture, assisted-conversion analysis and controlled prompt monitoring. Avoid claiming certainty where the data is incomplete.
