How much does SEO cost in the UK?

Ask five UK agencies what SEO costs and you will get five different numbers with no way to compare them. That is not because anyone is hiding something. It is because SEO is a label stuck on about six different jobs, and the price depends entirely on which ones you are buying.

So rather than quote a figure and move on, this article explains what sits inside a monthly SEO fee, what the common price bands actually buy, and how to work out whether a proposal in front of you is worth the money.

What you are actually paying for

A proper SEO engagement is made up of five separate workstreams. Most proposals include some of them. Very few include all of them, and the ones that claim to at a low price are usually doing each one badly.

Technical work

Making sure search engines can crawl the site, understand it and rank it: site speed, mobile behaviour, indexing, structured data, internal linking, fixing errors and broken redirects. This is front-loaded. There is usually a chunk of work in the first two months, then maintenance.

Content

Writing and improving pages so they answer the queries you want to be found for. This is where most of the ongoing hours go, and it is the part that produces most of the results. A month with no new or improved content is usually a month where nothing moved.

Digital PR and links

Earning mentions and links from other websites. It is the slowest and most expensive part, and the hardest to do ethically. If a proposal promises large numbers of links cheaply, they are being bought from somewhere you would not want your business associated with.

Local

Google Business Profile, local listings, reviews, location pages. For a business that sells within a fifty mile radius, this often produces more enquiries per pound than anything else on the list.

Reporting and strategy

Someone senior looking at what happened, deciding what to do next, and explaining it to you in language you can act on. Cheap SEO usually cuts this first, which is why so many people receive a monthly PDF full of graphs and no decisions.

The price bands, and what they realistically buy

Broad UK ranges for small and medium businesses. Treat them as orientation, because scope varies enormously.

Under £500 a month. This buys a handful of hours. It can work for a small local business with a healthy site, focused on local visibility and a piece of content every month or two. It cannot deliver a competitive national campaign, whatever the pitch says. Be careful at the bottom of this band, because the maths only works if the work is automated or offshored.

£500 to £1,500 a month. The most common band for UK small businesses. Enough for ongoing content, technical maintenance, local work and real reporting. A sensible place to be if you sell regionally or in a niche without brutal competition.

£1,500 to £3,000 a month. Serious content production, active technical work, some outreach, and a strategist who genuinely knows your market. Appropriate when search is a primary channel and the value of a customer justifies it.

£3,000 and up. Competitive national or ecommerce campaigns, several people involved, PR built in.

Two other models exist alongside retainers. One-off audits run from a few hundred pounds to a few thousand, and suit a business with someone in-house to act on the findings. Project work, such as a migration or a batch of new pages, is priced as a fixed piece and is a good way to start before committing.

The question that reveals a bad proposal

Ask this: what will you do in month one, and what will I see at the end of it?

A good answer is specific. An audit, a fixed list of technical issues, two new pages targeting named queries, the Business Profile sorted. A weak answer talks about optimisation, monitoring and ongoing improvements without naming a single deliverable.

Three more worth asking:

• Who does the work? The person in the meeting, or someone else entirely? There is nothing wrong with a team, but you should know who is writing your content.
• What do you need from me? Anyone who says "nothing" is not planning to write about your business in any depth. Good SEO needs your knowledge.
• What happens if I leave? Do you keep the content, the pages, the accounts? The answer should be yes to all three.

And one clear warning sign: anybody who guarantees a position in Google. Nobody controls the rankings, so nobody can guarantee them. It is the single most reliable indicator that you are talking to a salesperson rather than a practitioner.

How long before it pays for itself

For most small businesses, expect early movement at three months, meaningful change between six and nine, and the compounding benefit after a year. New websites and competitive sectors sit at the slower end.

That timescale is why cheap SEO is often the expensive option. Six months of hours spread too thinly finishes nothing, and you arrive at month seven with no results and no assets. The same money spent in a concentrated three month push usually leaves you with something.

To judge whether a fee makes sense, work out what one new customer is worth to you over their lifetime. If a customer is worth £3,000, one extra customer a month justifies a serious budget. If a customer is worth £150, the maths demands a very different approach, probably focused on local visibility rather than a full campaign.

Where AI search changes the sums

People increasingly ask an assistant for a recommendation instead of scrolling a results page. That does not replace search spending, but it does change what the work has to cover. Being quotable matters: clear answers under clear headings, structured data, consistent details across the web, and a site an AI can read without guessing.

The useful news is that most of this overlaps with good traditional SEO. The proposals to be wary of are the ones charging a premium for "AI optimisation" as a separate product, when in practice it should be part of how the work is done anyway. We fold it into SEO and GEO as one job rather than two invoices.

Common questions

Can I do SEO myself?

Parts of it, yes, and you should. Nobody knows your customers' questions better than you. Writing genuinely useful pages, keeping your Business Profile fresh and collecting reviews are all within reach. The technical work and the strategy are where outside help earns its fee.

Should SEO be tied into my website build?

Ideally yes. Structure, speed, headings and schema are cheaper to get right during the build than to retrofit afterwards. A site launched without them starts every campaign at a disadvantage.
