Top 5 SEO Agencies in London That Will Rocket Your Site to Google Stardom!
So, it was my day off when suddenly, I got a frantic call from a friend who runs a small bakery. She was convinced that Google hated her because her website wasn’t showing up in search results despite her famous double chocolate scones.
That got me thinking, maybe it’s not Google; maybe we just need some SEO magic! And that’s when I started finding the best SEO agencies, ones that could transform any underdog into a search engine superstar.
So here we are with my list of London’s top SEO agencies that will make sure Google loves you (as much as I love those double-chocolate scones). These agencies are pros at boosting your rankings, and driving traffic to your digital doorstep.
How much does hiring an SEO agency cost in London?
In London, you can expect to pay between £2,000 and £10,000 per month for hiring an SEO agency. The cost typically depends on the agency’s size, experience, and the scope of services provided. The higher end of the range is reserved for more established agencies that have a track record of delivering measurable results.
1. Rapid SEO London

Address: serves London
Phone: +44 208 123 1581
Business Hours:
- Monday to Sunday – 8 AM to 7 PM
Rapid SEO is one of the top SEO agencies you’ll find in London. What we love the most is their approach to digital marketing.
They offer everything from local digital marketing to UK-wide online advertising and even international campaigns to boost your global rankings.
We were pretty impressed by their live portfolio, too, showcasing previous clients who are currently ranking well. When it comes to ethical SEO practices, they’re all about white-hat tactics.
We had a good chat with their team, and they assured us that they’re always up-to-date with the latest algorithm changes, making their strategies both innovative and safe.
Communication-wise, they were crystal clear about costs and processes, breaking everything down without any jargon.
On the downside, a few of us think their pricing might seem a bit high if you’re on a tighter budget. Plus, we would’ve liked to see a bit more automation and tech-forward solutions in their operations.
But overall, what’s keeping us positive is the feedback from their clients and staff, who swear by their exceptional service and client-centric approach.
Honest and reliable approach
“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
Efficient and analytical methods
“Working with Rapid SEO for the past year has been wonderful. From the very beginning, Adam understood the brand, and our aims and values and his efficient and analytical approach to tackling our SEO needs was invaluable. From keywords and visibility to site optimisation and the incredibly informative monthly reports – I would highly recommend Adam and his team.”

2. Iconic Digital

Address: 7 Adam St.
Phone: +44 207 100 0726
Business Hours:
- Monday to Friday – 9 AM to 5 PM
So, we took the time to inquire and visit Iconic Digital, and let’s just say, they’ve got some serious games. They’re primarily a marketing agency, but their digital expertise is off the charts—especially when it comes to SEO.
They laid out to us their SEO service, which includes on-page optimization, link building, technical SEO, local SEO, and the whole shebang. What’s more, they mentioned that they offer a free SEO audit and super detailed monthly reports.
However, their rates are a bit high. Also, some of us think they could benefit from integrating more tech-forward, automated solutions to streamline things a bit more.
But, going back, another thing that impressed us was the range of services they cover. Apart from SEO, they’re also adept at paid advertising, email marketing, social media management, and even website and branding design.
Their ethical SEO practices really stood out too. We chatted with a few clients and staff, and everyone echoed how transparent and honest the team is.
Communication is a big thing with them, and the monthly reports are not just detailed but also transparent.
Highly recommended service, no reservations
“I was recommended Iconic by a business associate and have been absolutely delighted with the service I have received. I therefore have no hesitation recommending the firm to others.”
Harjit Jhooti, Google Review
Exceptional problem-solving and web expertise
“The whole team at Iconic Digital has been truly fantastic. Any problems which have come up during the building of our new website Iconic has come up with excellent suggestions which they are able to implement without any questions. I would highly recommend Iconic for any who requires their website to be refreshed or their social media channels to be managed. Thank you to the whole team especially Rosie and Seth.”

3. PN Digital SEO Agency London

Address: Kemp House, 152 – 160 City Rd.
Phone: +44 207 846 0130
Business Hours:
- Monday to Friday – 8:30 AM to 5:30 PM
PN Digital SEO Agency really stood out in our books, and the most impressive aspect was their deep expertise in SEO and PPC.
They are undeniably specialists in the field, offering comprehensive SEO services including e-commerce SEO, link building, customised SEO strategies, consulting, and specialised SEO for retail and Shopify websites.
Another thing that caught our attention was their prowess in integrating SaaS and AI technologies into their SEO services. This just shows that they’re ahead of the curve in incorporating modern tech solutions.
Now, previous clients we spoke with were quite happy with how transparent and open the team was. They also added that the agency maintains clear communication and regular updates without needing constant follow-ups.
We were even more impressed by their well-defined processes, ensuring that our unique needs are met with tailored strategies. Their attention to detail and customization is definitely a plus.
However, we’re just a bit iffy about the pricing—it’s higher than some other places. But, considering the high-quality service, we still find it pretty fair.
Successful long-term partnership
“An excellent company to work with. We’ve enjoyed a successful relationship for nearly two years and are confident that this partnership will continue for many more years to come”
Izabella Wicks, Google Review
Remarkable online sales growth
“If you have any doubts about partnering with PNdigital let me assure you that you shouldn’t be hesitant at all. Our experience working with them has been excellent. We have achieved a remarkable 93% increase in our overall online sales and the positive trend is continuing to rise.”

4. Ignite SEO

Address: 49 Stewart’s Grove
Phone: +44 203 150 0995
Business Hours:
- Monday to Friday – 9:30 AM to 5:30 PM
Ignite SEO has a stellar reputation as an SEO agency, offering e-commerce SEO, local, and national SEO services, plus SEO consulting and white label services.
What caught us was when they mentioned that their expertise spans a wide range of industries, from medical practices to restaurants and law firms.
Meanwhile, their free SEO consultation was a great starting point. We were happy with how they dived deep into our business’s needs before proposing a strategy.
But even with the free consultation, we still noted that their pricing is on the high side. Nevertheless, they’re not just about big talk; they’ve got a solid portfolio that’s accessible on their website.
We were even more impressed with their transparency and clear communication. They kept us in the loop without us having to chase them for updates, something about which other clients rave.
Moreover, they’ve got some state-of-the-art processes, combining ethical SEO practices with effective link-building strategies.
A few folks we come across highlighted how seamless the experience was from start to finish, always knowing what to expect next.
Highly engaging and informative talk on SEO and AI
“Adam Collins delivered a concise yet extremely informative talk at Nottingham City Business Club around SEO and AI. He packed a lot of great insights into a short space of time. I would have loved to have heard more. Highly engaging and well worth attending.”
Suzie Leveson, Google Review
Exceptional support and effective online business exposure
“I couldn’t recommend Ignite highly enough! They worked with me to maximise the ranking of my business based locally in London. From start to finish their support and advice helped me gain a more in depth understanding of how to effectively expose my business online. From communication to execution their service is second to none and I look forward to working with them again in the future.”

5. ClickSlice

Address: studio 10, Shoreditch Stables, 138 Kingsland Rd.
Phone: +44 203 287 3638
Business Hours:
- Monday to Friday – 9 AM to 5:30 PM
ClickSlice really has its stuff together, offering their expertise across the board. Not only do they excel in all types of SEO—be it ecommerce, Shopify, WooCommerce, or Adobe Commerce—but they also offer stellar SEO consulting, SEO, and PPC services.
We all agreed that this agency is like a one-stop-shop for all things digital marketing. Additionally, their office is quite the creative hub, which is inspiring to see as it breathes a collaborative spirit into their workflow.
We were glad to hear them mention that they dabble in digital PR and web design too. Moreover, their approach to SEO is ethical, which is another aspect that stood out to us, and their process is so transparent.
We just felt a bit iffy about their high pricing, which might be tight for small businesses or startups. Moving on, they make a solid effort in communicating each step with their clients and keeping everyone in the loop.
Clients we spoke to were really impressed with the constant updates and the honest communication around costs, so no surprises there.
Generous advice and transparency
“I contacted clickslice when looking for support on SEO/ Google ads. I spoke to Matt who was upfront with me that my budget wasn’t large enough to work with their agency. Matt spent the rest of the call answering questions that I had, giving me free advice on how to improve/ optimise my website to improve my lead generation. Really appreciate the help.”
Alexander Dear, Google Review
Remarkable keyword strategy and growth
“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!”
