Quick answer: Most businesses pay between £1,000 and £10,000 per month for AI SEO services in 2026, with the figure driven by scope, competition, and how much authority-building is involved. Small and local businesses typically sit at £1,000 to £2,500 a month, mid-market brands at £2,500 to £7,500, and enterprise programmes at £7,500 and up. One-off audits usually run £2,500 to £10,000.
What are you actually paying for with AI SEO?
Before you can judge a price, you need to know what sits behind it. AI SEO is not one task. It is a bundle of disciplines that work together to get your brand found in both traditional search results and AI-generated answers from tools like ChatGPT, Google AI Overviews, Perplexity, and Gemini. When you pay for AI SEO, you are usually paying for some mix of technical optimisation, content production, authority and citation building, and ongoing measurement.
The newer and most valuable layer is Generative Engine Optimisation, or GEO. This is the work of engineering your content and authority signals so that AI systems understand, trust, and cite your brand when they answer a user’s question. It overlaps with classic SEO but is a distinct discipline, and it is the part that most cheaply-priced providers quietly skip. If a quote looks suspiciously low, GEO and authority work are almost always what is missing.
A genuine AI SEO engagement also includes the unglamorous foundations: crawlability and site health, schema markup so machines can parse your pages, content structured for passage-level extraction, and a reporting layer that tracks not just rankings but AI citations and share of voice. You are paying for a system, not a checklist.
- Technical SEO and site health, so pages can be crawled and parsed cleanly.
- Content production structured for both readers and AI extraction.
- Authority and citation building across directories, earned media, and communities.
- GEO and AEO work to win AI Overviews, answer engines, and LLM citations.
- Measurement and reporting, including AI citation tracking and reporting cadence.
Typical AI SEO pricing in 2026
The honest answer is that AI SEO pricing spans a wide range because the businesses buying it span a wide range. A local plumber and a Series B SaaS company are not buying the same thing, so they should not expect the same invoice. The table below shows the ranges we see most often across the market in 2026, broken down by business size and engagement type.
Treat these as orientation, not gospel. The right number for you depends on how competitive your category is and how much ground you need to make up. A brand starting from zero authority in a crowded niche will pay more, and need more patience, than an established name making incremental gains.
| Business type | Typical monthly retainer | What is usually included |
|---|---|---|
| Local / small business | £1,000 to £2,500 | Local GEO, core content, citations, light technical |
| Mid-market / B2B | £2,500 to £7,500 | Full content engine, authority stack, AEO + GEO, monthly reporting |
| Enterprise / competitive | £7,500 to £25,000+ | Integrated GEO/AEO/AIO programme, PR-grade citations, multi-team coordination |
| One-off audit / project | £2,500 to £10,000 | Technical + GEO audit, roadmap, sometimes a content sprint |
The three main pricing models
AI SEO is sold in three broad ways, and understanding them helps you compare quotes that look very different on the surface. The most common is the monthly retainer, where you pay a fixed fee for an agreed scope of ongoing work. This suits AI SEO well because authority and citations compound over time; they are not built in a single sprint.
The second model is the one-off project or audit. Here you pay a fixed fee for a defined deliverable, such as a technical and GEO audit with a prioritised roadmap. This is a sensible low-commitment way to test a provider and to get clarity before signing up to anything ongoing. The third model is performance-based pricing, where some portion of the fee is tied to results. It sounds appealing, but be cautious: AI citations and rankings depend on factors outside any agency’s full control, so pure performance deals often hide restrictive terms or encourage short-term tactics.
- Retainer: predictable monthly fee for ongoing, compounding work. Best for most brands.
- Project / audit: fixed fee for a defined deliverable. Good for testing a provider.
- Performance-based: fee tied to outcomes. Attractive on paper, but read the terms carefully.
What makes the price go up or down?
If two agencies quote you wildly different numbers, it is usually because they have scoped the work differently, not because one is ripping you off. The biggest single driver is competition. Ranking and getting cited in a low-competition local niche is a fraction of the effort required in, say, B2B fintech where every competitor is also investing heavily.
Content volume and quality is the next lever. AI systems preferentially cite content that is specific, well-structured, and backed by data, and that kind of content costs more to produce than thin, templated articles. Authority building is the third lever and often the most expensive, because earning citations from directories, analysts, earned media, and credible communities takes genuine outreach and relationship work that cannot be automated away.
Finally, your starting position matters. A site with technical debt, thin content, and no existing authority needs remediation before growth work even begins. A healthy site with an established brand can skip straight to the high-leverage activities, which lowers the effective cost of progress.
How to tell whether a price is fair
A fair price is one where the scope, the expected timeline, and the reporting are all transparent. You should be able to see exactly what work is being done each month, what it is meant to achieve, and how progress will be measured. If a provider cannot or will not explain this clearly, the price is irrelevant because you cannot judge value.
Be wary of two extremes. Quotes that are dramatically below market usually mean automated, low-effort output with no real authority work, which produces little and can even harm you. Quotes that are dramatically above market should come with a correspondingly clear explanation of the additional scope, such as enterprise coordination or PR-grade citation building. The goal is not the cheapest invoice; it is the best ratio of credible work to cost.
- Green flag: clear scope, realistic timelines, and reporting that includes AI citations.
- Green flag: the provider can explain what GEO and AEO work they will actually do.
- Red flag: guaranteed rankings or guaranteed AI citations. Nobody can promise these.
- Red flag: prices far below market with no explanation of what is being skipped.
How MarGen thinks about pricing
At MarGen we price around outcomes rather than activity, because the point of AI SEO is visibility and citations, not a long list of tasks. Our engagements are built as an integrated programme that treats GEO, AEO, AIO, and search experience as one system, which means the price reflects the authority you are building, not just the articles you are publishing.
For most brands that looks like a monthly retainer scoped to their competitive reality, often preceded by a fixed-fee audit so both sides start with a clear, shared picture of the work. If you want a realistic number for your specific situation, the fastest route is a short conversation about your category, your current authority, and your goals.

MarGen runs AI SEO as one connected programme — the Synaptic Authority Engine — across three retainer tiers: Foundation (£1,950/mo), Authority (£5,950/mo) and Dominance (from £12,950/mo), each starting with a free audit.

Frequently Asked Questions
Is AI SEO more expensive than traditional SEO?
Often slightly, because it adds GEO and authority work on top of classic SEO. But the two increasingly overlap, and a good AI SEO programme covers both rather than charging twice.
Can I pay for AI SEO once and be done?
A one-off audit gives lasting value, but visibility itself needs ongoing work. AI citations and authority compound over months, so a single payment rarely produces durable results on its own.
Why do some agencies charge under £500 a month?
Usually because they rely on automated, templated output with no real authority building. It is cheap because little of substance is happening, and it can damage your site.
How long before I see a return on the spend?
Most brands see early movement in three to six months, with compounding gains after that. Treat anything promising results in weeks with suspicion.
Should I choose performance-based pricing to reduce risk?
It can work, but read the terms closely. Because citations and rankings depend on factors outside any agency’s control, pure performance deals often carry restrictive conditions.
