Almost every article about SEO pricing exists to avoid answering the question. They explain that it depends, list some factors, and finish with a form. That is a sales page wearing a guide’s clothes, and it wastes the time of the person who just wants to know whether they are being overcharged.
So here are numbers. Ranges, with what sits behind them, what each band actually buys, and how to tell an expensive quote from a bad one — which are not the same thing and get confused constantly.
The short answer
UK market ranges as I observe them in August 2026, from quotes clients show me and published freelance and agency rates. Not a survey — treat them as the middle of what you should expect to see, not a statistic.
Agencies run higher. A mid-range UK agency retainer is roughly £1,000 to £3,000 a month, and a professional or enterprise engagement runs £3,000 to £10,000 and upward. Some of that premium buys genuine specialism you cannot get from one person. Quite a lot of it buys account management, an office, and the salary of whoever sold you the contract.
Why the range is so wide
Not because some people are four times better. Because “SEO” is four different jobs sold under one word, and a quote is really an answer to which of these are we doing, and how much of it.
In short: The single biggest variable is the first one. Nobody can price the work honestly without looking at the site, which is why a quote offered before anyone has looked is a number chosen to win the enquiry.
What each band actually buys
Under £500 a month. Automated rank reports, a few directory listings, and perhaps a monthly blog post written by someone who has never seen your business. The maths is simple: at £300 a month, after tax and overhead, you are buying two or three hours. Two or three hours cannot research, write, publish and fix anything. The monthly report exists to make the invoice feel earned.
£800–£2,000 a month. The realistic small-business band. Enough for genuine keyword research, a few pages a month produced properly, technical problems fixed as they surface, and reporting a human wrote. This is where most local and small B2B businesses should be, and where a competent freelancer is usually better value than an agency at the same price.
£2,000–£4,000 a month. Programme territory. Whole-site content maps, several pages a month, technical work absorbed as needed, and enough hours to keep several areas moving at once rather than one. Worth it when you have a wide catalogue or several services, and wasteful when you have one page that needs to rank.
£4,000 and up. You are buying a team. That is correct for a national retailer or a business in a genuinely contested market. For a firm with twelve service pages, it is a Range Rover for the school run.
The four ways it gets sold
One-off audit or technical fix. Finite, defined, and the right purchase when something specific is broken — traffic dropped after a redesign, the site is slow, pages are not indexed. Priced £1,000 to £5,000 in the wider market, and lower from a freelancer with no report-writing overhead.
Monthly retainer. Ongoing production and maintenance. The right purchase when you need to keep publishing and keep pace. The trap is the retainer sold to a business whose site needed fixing once — you pay monthly for a job that had an end.
Day rate. £560 to £770 for senior freelance work. Excellent for a migration, a diagnosis, or training your team. Poor for ongoing SEO, because the work is spread thin across months rather than concentrated into days, and day-rate billing quietly pushes it into the shape that bills best.
Project. A rebuild, a replatform, an international rollout. Priced as a piece of work with a defined end, which is usually the honest structure when there is one.
What I charge, and why it is here
I would rather show you my numbers than write another article that will not.
A fixed-price technical fix is £599. Monthly plans are £1,999 and £3,999. Day rates exist for ad-hoc work. Everything is scoped before you commit and there is no lock-in — the pricing page has what each one includes.
Those sit at the lower end of the ranges above for a reason that is structural rather than generous: there is no office, no account manager, and no salesperson taking a cut. You get me, which also means I take fewer clients than an agency can. That is the trade.
How to judge a quote
Price is the last thing to look at. These are the questions that separate a real proposal from an expensive one.
Before you sign anything
0/ 7
That is the whole list. Anything still unticked is your next job.
Expensive is not the same as bad value
A £3,999 month that produces eight properly researched pages, fixes the technical faults holding them back and moves a converting cluster onto page one is cheap. A £499 month that produces a PDF is expensive, whatever the invoice says.
The number to work back from is what a customer is worth to you. If a new client is worth £2,000 over their lifetime, then two extra enquiries a month at a 30% close rate covers almost any retainer on this page. If a customer is worth £40, the arithmetic is completely different and most of this pricing is irrelevant to you — you need volume, and volume needs a different plan.
That calculation is the one worth doing before you ask anyone for a quote. It tells you what you can afford to pay, which is a much more useful number than what other people charge.
Common questions
How much does SEO cost per month in the UK?
Most legitimate UK monthly retainers sit between £800 and £4,000. Under about £500 a month there is not enough time in the budget to do research, produce pages and fix technical problems, so something is being skipped. Above £4,000 you are usually buying a team rather than a person, which is right for some businesses and wasteful for most small ones.
How much should a small business pay for SEO?
It depends far more on what needs doing than on the size of the business. A small firm with a sound site and one weak area might need a one-off fix of a few hundred pounds and nothing more. A small firm that needs its site rebuilt, its pages rewritten and its technical foundations repaired is a programme, and that is thousands. The honest answer comes from looking at the site, which is why any quote given before someone has looked is a guess.
Is cheap SEO worth it?
SEO at £99 to £300 a month is almost always automated reporting plus a handful of directory submissions. It is not fraud exactly — you do get something — but nothing in it moves rankings, and the monthly report is designed to look like progress. If a budget only stretches that far, spending it once on a proper technical fix will do more than spending it twelve times on nothing.
Why do SEO quotes vary so much for the same work?
Because 'SEO' is not one job. One quote may be a technical audit, another content production, another link acquisition, and a fourth all three with a project manager attached. Ask what gets produced each month rather than what is included, and the quotes become comparable very quickly.
What is a typical SEO day rate in the UK?
Senior freelance day rates generally run £560 to £770. Day rates suit a defined job — a migration, a diagnosis, a training session — and suit ongoing work badly, because the productive part of SEO is spread thin over months rather than concentrated into days.
Should I pay for SEO monthly or as a one-off?
One-off if the problem is structural and finite: a bad migration, a slow site, a missing page. Monthly if you need to out-publish and out-earn competitors over time, which is a compounding job that cannot be done once. Many businesses need the one-off first and only then have something worth maintaining.
