What Our Clients Say About Us
“I can highly recommend Atomic. We have been working with Atomic for some time now. They have designed and created 5 fantastic websites for us, with a complex back end system for our users, as well as some custom event software our users are able to utilize for our corporate events. We are now also in the final stages of launching apps through Atomic.”
“Obviously, the results are the most important thing for us, but so too has been their commitment and enthusiasm. It's clear they are committed and determined to deliver above and beyond expectations. Their overall style is highly collaborative. We have had weekly, online meetings with no less than 3 Atomic consultants present on each call.”
“We have noticed a marked increase in online bookings and enquiries for the events space. We have had lots of comments from customers saying how inviting the site is now, and how easy it is to navigate and make a booking. We were frequently updated by Timothy, who gave us lots of advice and guidance on design and always made himself available for any queries.”
“Our ROAS for our Facebook and Instagram campaigns has averaged around 4-6 with highs of 15 during peak selling time. Previously we had been seeing 0.5-2 with our own marketing. We were impressed with the way they really learnt to understand our business. Though it's likely different to any previous business model they have worked with.”
“I approached Atomic Digital Marketing to modernise and SEO optimise my old dinosaur of a web site. They firstly UX/UI designed and prototyped my new website and then built the entire thing within two months. Not only am i absolutely thrilled with the outcome of what they have produced, so too are my clients.”
“I needed to rebrand my website and Atomic handled the job very quickly, efficiently and without needing much from me which was great. It's very nice to work with a business that you feel has complete control of the work required - especially when you don't understand it yourself.”
“We have been working with Atomic now for over 6 months. They have built a new website, run our CPC and organics. So far so great and we have achieved all that we set out to do. Recommended!”
“The team did a great job at building a website for our first aid training business. I'd recommend Atomic to anyone looking for a good design which also has a focus on SEO site structure.”
“I always doubt the claims of 3rd party tech agencies but received 1st class, rapid service that was right on price and exceeded the deliverables that we had agreed with them. Atomic Marketing know their stuff and delivered for Evolution Power Tools. Easy to work with, quick to respond and exceeded our expectations. That doesn't happen often.”
“Atomic Digital Marketing helped the client generate leads and referral customers. The team was always available for any questions and calls to discuss elements of the website build. They used Agile methodology to iterate quickly and provide guidance on the UX experience. Tim, Justin, Robyn & Peter were always on hand to help.”
“We have been working with Atomic for the first half of the year now, and have offered a fantastic service, extremely knowledgeable and up to date with the latest marketing trends. Very tailored made to our company needs, and always very quick to respond! just a great team all round!!”
“As managing director at Enbi Global, it was made known to me that our SEO was suffering heavily. Atomic first conducted a site SEO audit which identified where our issues lay, and then subsequently worked on the website for the following week ironing these issues out. Following the work, our site optimisation score increased to around 94% and our rankings continued to improve.”

Google Tag Manager is a free tag management system that allows you to manage and deploy marketing tags (snippets of code) on your website without having to modify the code directly. It simplifies the process of adding tracking codes for analytics, advertising, remarketing, and more.
While GTM is a powerful tool, incorrect implementation can lead to data inaccuracies, site performance issues, and missed tracking opportunities. A specialist GTM agency ensures your setup is clean, accurate, and optimised — providing reliable data that drives better marketing decisions.
Yes. We implement server-side Google Tag Manager, which processes tags on a server rather than the user's browser. This improves site performance, enhances data accuracy, and provides better privacy compliance in a cookieless future.
