Walsh & Partners’ ultimate guide to help you decipher how much Search Engine Optimisation (SEO) services cost. A 2025 guide

 

Introduction

Businesses up and down the land will regularly purchase specific items and services that you will know the cost of from the top of your head.

However, search engine optimisation is a different kettle of fish.

Businesses globally often don’t know how much they should be paying- it can cause a lot of confusion as to what a company should be paying per month.

There is an old saying in Great Britain “that is you get what you pay for”; to a certain extent, this is true with SEO services. However, with that said, you don’t want to be paying through the nose.

Therefore, this comprehensive guide is here to enlighten you on how much you should be forking out.

 

Every website is entirely different.

Think of it this way for a moment: if you want to get your website to the top of Google’s organic search engine results pages, you have to approach the process like entering a race.

Now, what you will often find is that in the lucrative, highly competitive business sectors, companies will have their SEO perfected down to a fine art. Therefore, these business may have been diligently working on improving its SEO for thousands of man hours.

Therefore, a new website that thinks it can simply outdo the competition overnight will often be setting themselves up for a big mistake.

Good things come to those who wait.

Who likes Guinness? It’s a delightful drink, and its slogan is, “Good things come to those who wait”.

This is true with search engine optimisation; you could place millions of pounds on the table, yet sometimes it’s impossible to make things happen quickly. This is because of the following reasons:

• Link building velocity
• Google E-EAT
• Building trust
• Content marketing
• User data
• Analysing, seeing what works and building on that

 

Now, these are all critical topics, each warranting further explanation, so do go and grab a nice espresso as we explain why SEO can’t be rushed.

We understand it from a business perspective; directors all over the Great British Isles will want things done yesterday. And good SEO agencies, such as ourselves, will always aim to bring about a positive uplift in your organic rankings as soon as possible. The reason is that as you grow, a good digital marketing agency should aim to grow by your side.

However, Google puts some speed bumps in your way, which means you have to take things slowly and adopt a gentler approach. If you go SEO crazy, meaning you think that working crazy hours will move the needle in your favour, sometimes this can be a big mistake, leading to over-optimisation issues.

Plus, every aspect of the work must be focused on quality to satisfy Google EEAT. Then there’s shoppers, the real humans that use you site, to get high dwell times, with low bounce rates, well the work must be quality.

It’s a hard thing to do, and shouldn’t be rushed.

 

Let’s dive into some of the common pitfalls many businesses face:

Link building velocity (why you shouldn’t link build wildly)

You purchase a good link-building tool, log into it after all the staff have gone home, and say, ‘I’m going to do a bit of SEO myself.’

Good on you! We admire your ambition.

You log into an excellent backlink checking tool, such as Moz Pro, and then start typing your competitor’s website into the box.

You see that the top 4 results have a considerable number of links. You slam your hand down on the table, knowing that catching up will take a long time.

This is when businesses fall into the common mistake of trying to build backlinks quickly, or even worse, purchasing them. Then Google’s sophisticated and complex algorithms will detect that a large number of links are built at once, causing “link velocity” issues. If the links are then deemed as spam and low-quality, the business will inevitably incur a penalty, (Google Penguin) such as a link penalty.

Now, the reason we say this is that in an article that’s all about discussing SEO costs, it is simple. If you pay for bad quality work, this can majorly damage your business’s visibility, sometimes to the extent that the business is completely removed from Google because the company hasn’t followed Google E-E-A-T and Google Webmaster Guidelines.

So, returning to the Guinness saying: good things comes to those who wait.

Well we think this applies to SEO, if the work is good quality that’s being implemented.

 

Pay for quality

We would say that when it comes to finding an SEO freelancer, agency or marketing company, prices can often fall into two categories. First category is the ultra-low prices, where companies compete solely on price. This frequently means that the business’s seo is destined for a one-way street of complete and utter failure. Because, well, you usually get what you pay for.

On the other hand, often nestled in most cities or towns, will be an agency that does good work, yet has grown to the size where they no longer need to offer low prices; in fact, they sometimes charge eye-watering prices.

You need to find, therefore, that perfect balance between quality work and not paying the equivalent to large mortgage payment per month to receive such work. Consequently, you should work with agencies that let the results do the talking for you. They have a string of clients ready to sing their praises, simply because they have had such a profound and dramatic effect on the business’s overall success.

So don’t pay too much, don’t pay too little, find that company that’s in the middle, yet can demonstrate winning results.

 

Freelancer, agency and marketing company

 

Freelancer

A freelancer can often be the most affordable SEO option. Sometimes overlooked by medium to larger businesses. However, the right freelancer, one who is genuinely dedicated to doing a good job, can offer top-quality SEO services without the high markup that some agencies charge.

The problem with consultants and freelancers is there are only so many hours in the day. If they therefore get greedy, take on too may clients, they could end up neglecting some accounts to favour others.

What you have to consider is that when you go to some marketing agencies, sometimes one sole person is working on your account.

Sometimes, input from a copywriter is needed.

Therefore, you might want to consider partnering with the right freelancer in combination with a skilled copywriter who understands your business niche; this could be the ticket to saving money, rather than hiring a large agency.

Of course, however, the success of the SEO project ultimately hinges on how good the consultant is, which, from experience, can vary quite significantly.

 

SEO agency

An SEO agency is often the next step up.

Again, the quality of the services can vary massively, yet the prices are typically much higher than those of a freelancer.

The reason is that the different skill sets needed to complete the search engine optimisation work are brought in-house. The overheads, in terms of staffing costs can be vast, because you need link builders, copy writers, account managers. Yet again, the quality and experience of these staff vary massively; all agencies can’t therefore be tarred with the same brush.

For example, when getting detailed long-form evergreen content marketing written, you don’t need to go out and give a brief to your copywriter. That’s because in most agencies, there will be a copywriting team in-house.

This helps businesses save time, as it eliminates micro-managing the different aspects of search engine optimisation work. Often, this is all completed in-house.

 

Digital marketing agency

Perhaps the most expensive option is to opt for a full-service digital marketing agency, which has a whole team of web designers and web developers at your disposal. The reason is that you have a full range of skill sets that you can call on to help promote your business.
This can range from social media experts to PHP and WordPress experts, all under one roof, who implement the changes you want.

How much does SEO cost in the U.K. in 2025?

Let’s get down to brass tacks, how much do search engine optimisation services cost in the United Kingdom in 2025?

 

Agency, freelancer or marketing company

The first thing that your business needs to think about before you start your quest for an SEO company is what type of company you want to work for.

The reason is that typing “SEO consultant” into Google will often bring about a different set of results than if you were to type, say “, SEO agency” instead.

The reason is that there are many freelancers who often have relatively minimal overheads and typically work with a small number of clients.

This allows the business to pass on minimal overheads to the client, allowing smaller monthly retainers. Therefore these businesses generally want to rank on Google for “SEO consultant” keywords.

However, most agencies have either branched out into a wide range of marketing services or even offer web design services. Often, these businesses have offices in prestigious locations, such as those in the city centre. These businesses then have significantly larger overheads, which need to be considered. These businesses generally optimise their websites for “ SEO agency” keywords.

What you don’t want, for example, is to opt for a top-name agency in your city, to find that before they can get your business close to page one of Google, you run out of marketing budget.

Trust us, this is perfectly possible. For most start-up businesses, it takes over 6 months to get to the first page of Google for some keywords through local search engine optimisation. Some business sectors can take much longer. Therefore, you are paying top-end to receive such services from a leading agency. Well, your cash flow may dry up before they manage to raise the business through Google’s ranks and get you on page one of Google.

Do bear in mind when choosing a business.

 

How do I decipher whether I need a freelancer, a consultant or an agency?

• This boils down to three main factors, which we will detail below:
• Do you enjoy working in business?
• Can you manage the different aspects of work that you want completed?
• Is it a one-off set of tasks, or do you want to pay a monthly retainer?

Many agencies, including some consultants, are reluctant to undertake one-off work or tasks. Instead, they operate on monthly retainers, protected by fixed-price contracts. If you therefore want one-off work, there is often only one avenue: hiring a freelancer.

However, what you sometimes lose here is control over the quality of the work. The freelancer knows that you may never return for more work, so the quality could therefore be substandard, and possibly not even white-hat.

This is why many businesses prefer to establish a long-term relationship with a customer. This makes a lot of sense because ultimately, the responsibility for a company’s search engine optimisation success then rests with one company.
Because SEO requires a long-term marketing strategy, it’s far better to work with one business over the long run.

Comparing apples with pears

You ultimately have to be aware of this; every agency and consultant approaches their SEO tasks differently. Some have the Midas touch, so that everything they work on is a rip-roaring success.

Some other companies are out to make a quick buck. Therefore, what you have to be aware of is that there is the right way to follow Google’s SEO rules, called white hat optimisation, and then the opposite end of the spectrum are businesses which are flying against the rules, and using black hat methods. Like the plague, you will want to avoid the black hat methods, as they can attract problems, such as hefty Google penalties.

 

Needs to wear many hats

If you have a freelancer or an agency that doesn’t keep up with the best SEO practices, they will swiftly fall to the wayside. Just like last year’s fashion garments, they will be cast aside, destined to only compete on price.

Therefore, you need an agency or consultant that keeps its finger on the pulse. How do you check for this?

Where do they rank on Google?

Do not get us wrong, this is not a foolproof way of analysing if the agency is the bees ‘ knees.

However, suppose a company ranks at the top of Google for highly competitive search terms. In that case, it indicates that they have a solid understanding of how to optimise their own business for the top spot on Google.

Now, whether that same set of people or person applies the same standard of SEO work on your website is another kettle of fish. However, it does show a level of understanding that they know how to get a business to rank at the top of Google if the agency ranks at the top of Google themselves.

The next thing is that you want a well-rounded SEO consultant working on your website. Now, you don’t want to stroll into an agency and start integrating the individual based on their level of marketing knowledge. This is likely to get the business arrangement off on the wrong footing.

Instead, have a nice coffee with the staff, and say we want help with all aspects of our search engine optimisation, from technical issues to content marketing to link building. Therefore, make it clear you want the full spectrum of SEO knowledge applied to the website; consequently, you want the best consultant working on your site.

What you don’t want is someone who’s just started at the agency, has changed careers and could be possibly learning the ropes. This is why sometimes you’re better with a consultant who may work independently but has decades of experience, which some agencies may lack. If they do, they are sometimes reserved for those considered the primary income earners of that agency. Therefore, smaller agencies, which charge less for their SEO retainer, sometimes have less experienced staff working on the website.

 

But how long will we need to pay for?

SEO is a bit like building sandcastles as the tide comes in.

The reason is that you could be diligently working on your website, move up the ranks, and enjoy an influx of new customers.

Yet biting right at your heels will always be a new set of competitors, ready to boot your website back down Google’s ranks. Therefore, the competition is constantly analysing your work, seeing how you got to the top of Google.

Then, through a process we like to call reverse engineering, they can improve on your efforts so that they can rank higher. And so, this goes on in a constant cycle. Therefore, this is why search engine optimisation never really comes to a stop, because as soon as the foot slightly lifts off the pedal, a new influx of businesses is more than ready to take your position on Google.

It’s, therefore, a constant struggle, a battle that never really ends.

 

Google algorithm updates

What’s important to remember is this: you could have the best SEO minds globally working on your website, and therefore have an unlimited marketing budget.

However, Google can roll out significant “Google core updates” at any time it chooses. Ultimately, businesses that have implemented high-quality work are largely unaffected.

With that said, what can happen is “ranking flux,” which can occur and last for many weeks. This can essentially do something that our marketing agency describes as “disturbance in the force,” just like in Star Wars.

Meaning that your keyword positions on Google can fluctuate massively during this time. Therefore before you decide to pick up the phone, and give your SEO agency a good telling off, you do need to make sure whether a Google algorithm is underway, because even the best work in the work, can go through a period of ranking flux, where the keyword positions can sometimes sharply change until Google is finished with its roll out.

 

Location, location, location

It is a great TV show, for sure; however, location has a bearing on U.K. SEO costs.

For example, if you are nestled into the city centre of London, of course, you will pay more when compared to an agency in Cardiff. If face-to-face meetings are your preference, then you may want a local marketing company on your doorstep.

However, for some companies, a good old-fashioned phone call now and then may be appreciated to keep them updated. Therefore, if you are located in one of the U.K.’s larger cities, where costs will inevitably be higher to run a business, you may want to choose a company that’s slightly further away in another city, which offers lower prices.

To give an example, Bristol is a stone’s throw away; it’s not far at all. Fire up the sat nav, and one of our staff could be there in low traffic in less than an hour. However, the cost of SEO services between Cardiff and Bristol is vast. We mention this because often you will want to invest over the long run; therefore, if you could save money by choosing an agency in a neighbouring city, then why not do just that?

The problem with guaranteed rankings

We all like guarantees and certainty.
If a particular electrical item malfunctions and stops working, we often appreciate the fact that there’s a long guarantee period, allowing us to obtain a refund.

What’s wrong with a bit of certainty?

When it comes to SEO, we urge you to be cautious of businesses that claim to guarantee top positions or the number 1 spot on Google.

The reason is that we have heard businesses say they have got their client to number one in a matter of a few months.

Which sounds great; it sounds like the job’s done, let’s go down to the pub for a nice, refreshing drink.
But hold your horses.

What often happens here is that the agencies optimise the website, and move it to be optimised for a bunch of keywords that no one in the country is looking for.

So instead of saying “plumbers + city” name, they optimise the website for “emergency plumbers who can call out in the dead of night”.

Which is rubbish, but technically a first-page or first-position term. Technically, the way they have worded their SEO contracts, they have sometimes satisfied the first page ranking obligation. Yet, you receive no phone calls, no customers, just an SEO salesman with a blank expression pasted across his face.
