Digital Marketing Review from Michael Fratangelo
We had a great experience with Pearl Lemon. Our account manager, Dimple was quick to respond to my enquiry and provide a quote and timeframe for delivery of HTML coded emails. The price was really reasonable and they actually delivered the template ahead of schedule! We also had some feedback on the final product which they rectified promptly and free of charge.

Janine Sudbury's Review Sourced from Google
I’ve been working with Guy for just over two years now, across multiple websites and brands — and I can honestly say, he’s in a league of his own.His SEO expertise isn’t just theoretical — it delivers. Thanks to Guy’s guidance, I’ve consistently secured page one rankings for competitive keywords, and seen tangible results in traffic, engagement, and conversions.But what sets him apart is his blend of sharp strategy and human insight. He genuinely takes the time to understand your business and voice — no generic SEO templates or cookie-cutter advice. He’s collaborative, clear, and incredibly responsive, even when juggling multiple complex projects.If you're serious about building a strong online presence and want someone who’s both technically brilliant and great to work with — Guy’s your guy. Highly, highly recommended.

Guy proactively reached out to me to explore a collaboration and I’m happy that he did. We’ve since met face-to-face and he was very generous with his time and knowledge. Most impressively, my business and my website was able to benefit from his expertise with some incredibly quick wins; notably by securing a page 1 ranking within 48 hours of our meeting for a high-volume search phrase.

Imogen Aitchison's Review Sourced from Google
Adding to my 5* review from 4 years ago to add that Atomic have continued to provide invaluable advice and support. They are very responsive and great at problem solving. Still 🌟🌟🌟🌟🌟 in 2025!I got quotes/design ideas from several agencies for my website. Atomic stood out from the start. They listened to what I wanted and produced a very comprehensive, detailed and competitive plan. They understood my needs as a small business owner and delivered exactly the aesthetic I was after. They were also incredibly patient with the many tweaks and changes needed along the way. They worked extremely hard to find solutions when challenges arose, their communication skills were exceptional and they were willing to train me up so I could make basic updates and changes myself. Very professional and approachable. I’m really glad I chose them!

Have work with Atomic now for over 7 months and I have to say that is the best Digital Marketing Agency I have worked with in my 20 years career. They are pros that know what they are doing, get things done and more importantly, deliver results. I would like to mention Simon, Rachel, Tim and Justin, thank you for your work and support always! 100% recommend them.

We've been using Atomic Digital Marketing for web hosting and ongoing website maintenance, and they’ve always delivered a reliable and responsive service. Recently, they've supported us with some UI improvements and are now helping implement important compliance updates following our company’s acquisition. Special thanks to Timothy and Amr, who have both been incredibly helpful and supportive throughout – their attention to detail and quick turnaround times have made a real difference. Highly recommended.

Alan McKechan's Review Sourced from Google
Sarah at Digital Flourish ran a fantastic digital marketing campaign for WOW Youth Musical Theatre's production of Legally Blonde. The heart of this was her Meta advertising, using data brilliantly to optimise the campaign and ensure every penny of our budget was spent as efficiently as possible. She also created a striking landing page, tracking views effectively to measure true engagement.We are already using her excellent landing page structure for our upcoming production of We Will Rock You. She has also seamlessly set up a new mailing list for long-term audience reach, independent of Meta.I can't recommend Digital Flourish highly enough for any Weymouth businesses looking to run Facebook advertising campaigns. Their expertise is outstanding and delivers real, measurable results!
