Top 5 SEO Agencies in London That Can Actually Boost Your Brand
Nowadays, SEO is an essential part of life. Sure, it was tough to understand at first, but I soon realised, after laying it out very simply for me, that it could help boost my brand.
So I did it, and man, it feels good to see your business on the first page of Google results. In the digital world, it means you finally made it!
Well, I’m not gatekeeping this. Below are our trusted SEO agencies in London that my team and I have used to finally outrank the competition!
How much does an SEO agency cost in London?
An SEO agency in London costs around £500 per month for basic services, while premium plans are about £2000 or more. Factors that will affect the total prices are the inclusions, type and size of business, and add-ons.
1. Figment Agency

Address: Health Foundry, Canterbury House, 1 Royal St
Contact: 020 3642 2228
Business Hours:
- Monday – Friday: 9 am – 6 pm
- Saturday – Sunday: Closed
Most of our staff really liked Figment Agency because of their expertise. It’s easy to see why they’re a favourite because their team is full of SEO specialists with a positive track record.
When we checked their portfolio, we were impressed with how they managed to increase organic traffic and get their clients in the top rankings. And they did this for small and big clients!
These guys specialise in healthcare and professional services, which is cool because they have a wide reach. But that still means they’re not equipped for other industries.
That’s alright, though. From what we’ve seen, their holistic approach to SEO has helped their clients grow their businesses, probably due to their simple yet systematic framework.
Their SEO plans are reasonably priced as well, especially when you consider the inclusions. Plus, we love that they tailor the nitty gritty to ensure your business will have what it needs.
Exceptional impact!
“Exceptional impact!
We hadn’t had any SEO work done on our website before, we primarily relied on referrals. I’ve been super impressed with the impact they’ve made and working with their team is great as they are incredibly knowledgeable and consistently exceeded expectations. I highly recommend them to any business looking to strengthen their online presence. Looking forward to our continued partnership.”

2. ClickSlice

Address: Studio 10, Shoreditch Stables, 138 Kingsland Rd
Contact: 020 3287 3638, [email protected]
Business Hours:
- Monday – Friday: 9 am – 5:30 pm
- Saturday – Sunday: Closed
Here’s what we like about ClickSlice: they’re an e-commerce growth agency that helps increase sales for London businesses. We also like the strategy they use to achieve this.
Basically, they use a combination of marketing tactics to boost sales. They use SEO, PPC (pay-per-click), content, and social media marketing.
Plus, there’s no need for long-term contracts. We appreciate this a lot because it shows that their SEO team can deliver results.
They’ve proven that, too! When we looked at their case studies, we were surprised at the huge increase in organic clicks and revenue from the businesses they worked on.
They’ve partnered with large and popular e-commerce businesses, but they’re not ideal for other industries. Still, their SEO expertise is impressive since the UK government even hired them for training!
It’s unique that they don’t have SEO packages, which also means they aren’t budget-friendly. But instead of cookie-cutter plans, they tailor each service to suit the client’s business!
Valuable and capable SEO partner
“ClickSlice has proven to be a valuable and capable SEO partner. For me it was their attention to detail, they discovered amazing keywords for us to target on our commercial pages, as well as on our blog. From the first month of the campaign we’ve seen a steady increase in organic traffic. Our main target page is up 37% in comparison to last year and it’s only been 16 weeks. Josh has stated that this is only going to compound in the coming weeks too which is exciting to hear! If you’re looking for an SEO agency, give them a shot!”
– Bill Cheema, Google Review
A game-changer
“Partnering with ClickSlice has been a game-changer for our eCommerce business. Their detailed analysis and tailored optimizations increased our website traffic by 83% and boosted our revenue by 20% year-over-year. The team provided consistent updates and made us feel valued with their exceptional customer service. I highly recommend ClickSlice for anyone looking to enhance their online presence and drive growth. Their expertise and effective strategies set them apart in the SEO industry. Thanks to their efforts, we look forward to continued success and growth.”

3. Rapid SEO London

Contact: 020 8123 1581, [email protected]
Business Hours: Monday – Sunday: 8 am – 7 pm
Rapid SEO London is the kind of agency that offers cost-effective solutions. They’re actually a really inexpensive option.
It became clear when we inquired— their SEO services start at £495 per month, which is really affordable! On top of that, they provide free audits and don’t require contracts, so you can hire them on a month-to-month basis.
They also make SEO accessible for London businesses. They specialise in providing fast and direct SEO, all while not requiring a minimum contract (except for an understandable 3 months for new clients).
They have packages for different kinds of businesses, which is brilliant because you can find the right fit for your business. They also offer local and international packages.
But for an SEO agency, we think their website needs an upgrade. It’s also a bummer they don’t have in-house web designers.
On the plus side, their customer support is available even on weekends! Talk about fast responses!
Level of service is impeccable
“The level of service is impeccable. Adam and Lisa have month on month gained and held good rankings for my website resulting in more enquiries and bookings. They are honest and reliable in their approach and never try to sell additional services which I experienced with other companies that I’d worked with in the past. I would recommend Rapid SEO if you are looking to gain more business through website traffic. It is always a pleasure to receive a monthly report with positive results. Work promised is delivered on time and both Adam and Lisa go the extra mile to get results. Glad I found them”
– AT Beauford, Google Review
They really get results
“We were really hesitant about hiring an SEO company (there are soo many sharks out there!), but we are soo happy that we found Rapid SEO. These guys are amazing! They really care about their customers and what’s more they really get results, always going above and beyond. If you’re considering an SEO company, but don’t know who to trust, look no further. These guys are the real deal. You won’t regret it.”

4. Pearl Lemon

Address: Kemp House, 152 – 160 City Rd
Contact: +44 20 7183 3436, [email protected]
Business Hours: 24/7
Our staff was super impressed with Pearl Lemon for many reasons. One of which is their availability—they’re open 24/7, which makes them super accessible for local and international clients!
These guys can deliver organic traffic, and we can see why. They’re a full-service SEO agency that’ll will bring all the things you need to the table, such as free audits, increasing organic visibility, and addressing issues that affect your rankings.
Plus, they’re equipped to handle small and large businesses. They have an impressive list of clients that include high-end companies from various industries.
You do have to stay for 6 to 12 months, though, which can be tough on the bank account because they’re not exactly cheap (their services start at £3000 to £10000 a month).
But we understand their rates. Their strategy is strict and detailed, which has delivered positive results based on the case studies we saw.
SEO services are exceptional
“Pearl Lemon’s SEO services are exceptional! Their team’s expertise and innovative strategies have significantly improved my website’s visibility and organic traffic. They are professional, knowledgeable, and always ready to provide insightful guidance. Their dedication to achieving the best results truly sets them apart. I highly recommend Pearl Lemon for anyone looking to enhance their online presence with top-notch SEO services!”
– Olamide Saliu, Google Review
Results speak volumes
“Pearl Lemon has been an absolute game-changer for my business’s online presence. The strategies they implemented led to a noticeable boost in our website traffic and improved search engine rankings. Their SEO expertise is unmatched, and the results speak volumes.”

5. Cash Cow Marketing

Address: 5 Merchant Square
Contact: 0203 8238984, [email protected]
Business Hours:
- Monday – Friday: 8:30 am – 6 pm
- Saturday – Sunday: Close
Cash Cow Marketing lives up to their name. We’ve actually seen them provide concrete outcomes that have boosted sales, and it’s pretty obvious why.
They use a data-first approach, which uses different kinds of elements, like analytics and user behaviour, to create goals for the business. We’ve seen the effectiveness of their strategy through their case studies.
The clients we spoke with have had positive results, landing at the top of Google search results that have driven organic traffic. With their in-house team of SEO and social media experts, it’s understandable how they’ve managed to do this.
They work with different kinds of businesses as well, such as professional and e-commerce services. What’s brilliant is they don’t require long-term commitments, so you can pay on a monthly basis.
They don’t have weekend consultations, unlike others. But the no-obligation consultations are a plus!
Whole process was highly professional
“Absolutely brilliant experience. Right from the start I had great confidence that Enrico understood what I needed from the website, is hugely knowledgeable and knows exactly what to ask me to get to a fabulous result. He gave me great confidence throughout that we would not only get a website that exceeded my expectations, but also that I would receive the support to take the site on and make it really work for the business plus be prioritised in searches. The whole process was highly professional, thorough and smooth. I’m so glad I went with Cash Cow and I highly recommend them and Enrico to anyone who wants an excellent website.”
