The four pricing models
Most SEO work is sold in one of four ways. Each has genuine use cases and genuine limitations.
Hourly
The most transparent model. You pay for time, and you can see exactly what that time produced. Typical rates in the UK range from £75–£150/hr for experienced freelancers to £150–£350/hr for senior agency staff or specialists.
Hourly works well for one-off audits, specific technical problems, or consultancy alongside an in-house team doing the execution. It's less suited to ongoing work where the volume of effort is variable month-to-month — you end up having a conversation about the invoice every time.
Monthly retainer
The dominant model for ongoing SEO. You pay a fixed monthly fee; the agency or freelancer delivers an agreed scope of work. Retainers provide predictable costs and allow the practitioner to plan their time properly.
The risk: retainers create an incentive to do the same things every month regardless of whether they're the right things. A good retainer should have a clear scope, clear deliverables, and a quarterly review of whether the priorities are still correct.
Project-based
A fixed price for a defined piece of work: a technical audit, a content strategy, a site migration plan. Projects work well when you have a specific problem with a clear scope. They require the practitioner to estimate accurately and carry the risk of underestimating.
Watch for scope creep clauses. A project "audit" that doesn't include fixing any of the issues found requires a separate engagement — make sure you understand what's in scope before signing.
Performance-based
Payment is tied to outcomes: rankings achieved, traffic delivered, conversions generated. In theory this aligns incentives perfectly. In practice it creates serious problems.
Rankings are influenced by factors outside the practitioner's control: algorithm updates, competitor activity, site changes you make independently. Performance models tend to reward gaming easy metrics (ranking for low-competition terms, driving irrelevant traffic) rather than the outcomes that actually matter to you. Treat them with caution.
What to expect at different budgets
These are UK market figures in 2026. Budgets in the US tend to run higher; smaller markets or less competitive industries may run lower.
Under £500/month
You're in freelancer territory, and that's fine for the right situation. A capable freelancer at this budget can run basic technical monitoring, advise on content, and handle straightforward on-page work. You won't get link building, content creation, or strategic direction at any scale.
This budget works if you have an in-house team executing and you need expert oversight, or if your site is small and the competitive environment is low. It doesn't work if you're in a competitive niche and expecting to out-rank established players.
£500–£2,000/month
A working budget for a small business with real SEO ambitions. At the lower end, you're getting a freelancer with bandwidth for proper work. At the higher end, you're getting a small agency or a senior freelancer.
Expect: monthly technical monitoring, basic content strategy, some on-page optimisation, and perhaps light link building or digital PR. Expect not to get: heavy content production, aggressive link building campaigns, or a team of people.
£2,000–£10,000/month
Where serious SEO happens for competitive industries. A full-service agency at this budget can run technical SEO, a content programme, and a link-building operation simultaneously. You should expect regular reporting, a dedicated account manager, and measurable progress against agreed KPIs.
At the top of this range, you can also engage specialist agencies — those that focus exclusively on technical SEO, or on digital PR, or on a specific sector.
£10,000+/month
Enterprise SEO. At this level you're typically working with a large agency or a combination of in-house resource and specialist suppliers. The complexity justifying this spend usually involves: large sites with hundreds of thousands of pages, international or multi-lingual search, highly competitive verticals (finance, legal, health, ecommerce at scale), or brands where search is a primary revenue channel.
The return on investment at this level is well-documented when it's working: enterprise SEO can drive millions in incremental revenue. The failure modes are also well-documented: agencies billing for activity rather than outcomes, internal politics slowing implementation, and technical debt that makes the site difficult to optimise.
Why "packages" are partly fiction
Most SEO package naming — "Starter", "Growth", "Enterprise", "Silver", "Gold" — is marketing shorthand. It bundles a set of activities at a price point and gives it a name. The problem is that SEO requirements vary enormously by site, industry, current state, and competitive environment.
A "Growth" package at £1,500/month might be exactly right for an SME in a mid-competitive niche and wildly insufficient for a business trying to compete in personal finance. The package name tells you nothing about whether it's the right intervention for your situation.
The better question to ask any supplier isn't "what does your package include?" but "what does my site specifically need, in what priority order, and what will it realistically cost to get there?" If they can't answer that without knowing more about your site, they're selling a product, not a service.
DIY and tools
For smaller sites and lower-competition environments, doing SEO yourself is genuinely viable. The investment is time rather than money. Our tools section covers the free utilities worth using, and the articles section covers practical technique. The glossary is useful for getting fluent in the terminology quickly.
The main paid tools worth knowing: Ahrefs and Semrush for keyword research and competitor analysis (both have basic free tiers), Google Search Console (free, essential), and Screaming Frog for site crawling (free up to 500 URLs). These cover the majority of what you need for most sites.
