How We Rated These Agencies
Every agency on this list was scored using SEOCompare's proprietary framework. We look at five areas:
- AI platform coverage - How many AI platforms does the agency actively monitor and optimise for? The best cover 4 or more.
- Methodology - Does the agency have its own framework for AI search, or is it bolting AI onto traditional SEO?
- UK market expertise - Does the agency understand UK search behaviour, pricing, and business culture?
- Pricing transparency - Can you see pricing before speaking to sales?
- Published results - Has the agency shared before-and-after AI citation data?
Specialist vs Generalist AI SEO Agencies
The biggest decision is whether to hire a specialist or a generalist. Specialist agencies like Rank4AI exist only for AI search. They tend to cover more platforms and use frameworks designed for how LLMs evaluate sources.
Generalist agencies like Impression and SEO Works offer AI SEO alongside traditional SEO, PPC, and content marketing. This works well if you want one agency for everything. The trade-off is less depth on AI-specific tactics.
If AI visibility is your top priority, go specialist. If you need AI SEO as part of a wider digital strategy, a generalist may suit you better.
What to Ask Before Hiring
Before signing with any UK AI SEO agency, ask these questions:
- Which AI platforms do you monitor? Look for at least ChatGPT, Gemini, and AI Overviews. The best cover 5 or 6.
- What is your AI search framework? Agencies with their own method tend to deliver better results than those adapting traditional SEO.
- Can you show AI citation data? Ask for before-and-after examples of client mentions in ChatGPT or Gemini responses.
- How do you measure success? Good agencies track citation frequency, sentiment, and position across each AI platform.
- What is your minimum contract? Most UK agencies ask for 3 to 6 months. Avoid 12-month lock-ins unless results justify it.
UK AI SEO Pricing Guide
UK AI SEO agencies charge between £1,200 and £3,000+ per month. Here is how pricing breaks down:
| Tier | Monthly Cost | What You Get |
|---|---|---|
| Entry | £1,200 - £1,500 | AI audit, 2-3 platforms monitored, monthly reporting |
| Mid-range | £1,500 - £2,500 | Active optimisation, 3-4 platforms, content recommendations |
| Premium | £2,500 - £3,000+ | Full-service AI SEO, 4-6 platforms, entity and schema work |
| Enterprise | £5,000+ | Multi-market, custom dashboards, dedicated team |
Most UK SMBs spend between £1,500 and £2,500 per month on AI SEO. The best value comes from agencies that combine strong methodology with reasonable pricing.
Common Mistakes When Choosing an Agency
Businesses often make these mistakes when picking an AI SEO agency:
- Choosing on price alone - The cheapest option rarely covers enough platforms or has deep AI expertise.
- Ignoring platform coverage - An agency that only monitors Google AI Overviews misses ChatGPT, Gemini, and Perplexity traffic.
- Not asking for AI-specific results - Traditional SEO case studies do not prove AI search capability.
- Signing long contracts early - Start with a 3-month trial before committing to longer terms.
- Assuming all AI SEO is the same - Each AI platform uses different signals. Agencies that treat them as one thing will underperform.
