Picking out the single ‘best’ SEO agency in the UK is pretty much a no-go. Every business has its own goals, budgets, and audiences, so the right fit really depends on what you need, not just who’s at the top of the list.

SEO pricing in the UK varies significantly based on your business size, goals, and the complexity of your project. Most reputable agencies work on monthly retainers rather than one-off fees, because SEO is an ongoing process that requires consistent effort and adjustment.
For small businesses looking for local SEO support, you might expect to pay anywhere from £850 to £2,000 per month. This typically covers basics like Google Business Profile optimisation, local citations, and content updates.
Mid-sized businesses with broader organic growth goals usually invest between £2,000 and £10,000 per month. At this level, you’re looking at comprehensive strategies including technical SEO, content creation, link building, and regular reporting.
Enterprise-level SEO for larger organisations or competitive industries can range from £10,000 to £50,000+ per month. This includes dedicated teams, advanced technical work, international SEO, and integration with wider marketing strategies.
It’s worth remembering that cheaper isn’t always better. SEO done poorly can actually harm your rankings, so focus on value and proven results rather than just the lowest price. Most good agencies will offer a free consultation or audit to give you a realistic sense of what’s needed and what it’ll cost.
If we’re being completely honest? SEO takes time. Anyone promising first-page rankings within a few weeks is either targeting very niche keywords or not being straight with you.
For most businesses, you should start seeing some initial improvements within 3 to 6 months. This might be better rankings for less competitive keywords, increased organic traffic, or improved site health metrics. The real momentum typically builds between 6 and 12 months, when your content starts gaining authority and your technical improvements compound.
That said, SEO is never truly “finished.” Search algorithms evolve, competitors improve their own SEO, and user behaviour shifts. The best results come from treating SEO as an ongoing investment rather than a one-off project.
Several factors affect how quickly you’ll see results:
The agencies in this guide understand these realities and will set honest expectations from the start. Be wary of anyone who promises overnight success.
Choosing the right SEO agency is a big decision, so it’s important to ask the right questions upfront. Here are the essentials we’d recommend covering in your initial conversations:
About their approach:
About their experience:
About reporting and communication:
About expectations:
About the contract:
We’ve actually got a more detailed guide on 15 questions to ask when hiring a digital marketing agency if you want to dig deeper.
This depends more on your business goals than your physical location. Here’s how to think about it:
Choose a local agency if:
Choose a national or remote agency if:
The truth is, in 2025, location matters less than it used to. Most SEO work happens online anyway, and video calls have made distance irrelevant for communication. What really matters is finding an agency that understands your business, your audience, and your goals.
Many of the agencies in this guide work with clients across the UK and beyond, regardless of where their offices are based. Alba SEO Services is Edinburgh-based but has clients throughout Scotland. Koozai works with businesses nationwide, as well as overseas, but is based in the UK and the team all work remotely. Rise at Seven has global clients despite being UK-founded.
Focus on expertise, results, and chemistry with the team rather than whether they’re around the corner.
Both are essential parts of a complete SEO strategy, but they focus on different aspects of how your site performs in search.
Technical SEO is all about the behind-the-scenes work that helps search engines crawl, understand, and index your website properly. This includes:
Think of technical SEO as making sure your website’s foundations are solid. If search engines can’t properly crawl your site or if pages load slowly, even brilliant content won’t rank well.
Content SEO focuses on creating and optimising the actual content on your pages to match what users are searching for. This includes:
Content SEO is about making sure you’re saying the right things in the right way for both users and search engines.
The best SEO agencies (including those in this guide) understand that you need both working together. Brilliant content on a technically broken site won’t rank. A perfectly optimised site with thin, unhelpful content won’t either.
At Koozai, for example, we combine technical expertise with strong content and digital PR capabilities, because that’s how you get sustainable, long-term results. Most of the agencies featured here take a similar holistic approach.
There’s a lot of noise in the SEO world, so knowing who to trust can be tricky. Here are the signs we’d look for when evaluating whether an agency really knows their stuff:
Red flags to watch out for:
Green flags that signal quality:
You can also check independent review platforms like Trustpilot, Clutch, or Google Business Reviews to see what real clients say. Look for patterns in the feedback rather than just the star rating.
And don’t underestimate chemistry. You’ll be working closely with your SEO agency, so you need a team you trust and enjoy collaborating with.
This is one of the most common questions we hear, and honestly, there’s no single right answer. It depends on your business size, budget, and long-term goals.
Consider an agency if:
Consider in-house if:
The hybrid approach: Many businesses actually get the best results by combining both. You might have an in-house SEO manager or coordinator who works day-to-day on content and optimisation, supported by an agency that handles technical audits, link building, and strategic planning.
This gives you the business knowledge and responsiveness of in-house, with the specialist expertise and scalability of an agency. It’s an approach we see working really well for mid-sized companies looking to grow.
Whatever you choose, make sure you’ve got the right people with the right skills. One junior SEO executive trying to do everything rarely delivers the results you need.
This is the million-pound question, and the honest answer is: it depends on where you’re starting from and what you’re trying to achieve.
Realistic expectations for most businesses:
Months 1-3:
Months 4-6:
Months 6-12:
12+ months:
But here’s what good agencies focus on beyond just rankings:
The best agencies in this guide won’t just talk about ranking positions. They’ll help you understand how SEO contributes to your bottom line, whether that’s sales, leads, bookings, or brand awareness.
Every business is different, so a good agency will set bespoke KPIs based on your specific situation. If someone’s promising you generic “first page rankings,” dig deeper into what that actually means for your business.
If you want to understand what’s realistic for your specific situation, most agencies (including Koozai) offer free consultations or audits where they can give you a clearer picture.
And if you’d like to speak with a team that really listens to what you’re trying to achieve?
