Web Development Review from Micah Steytler
We gave them our requirements for the website. They were in charge of the UX/UI design and the whole development process. DiscoverMyBusiness put all the features that were required in place, including an enhanced search engine that lets consumers browse for commercial real estate whenever they want using various business criteria. They also included a function that lets users list homes for sale or leasing.
Social Media Marketing Review from Joe Parlett
We needed someone to curate, create and manage our social media platforms. we especially wanted someone to manage our growing community. Once we met with all the team members, socially in got to work creating our tone, voice and social media strategy. I believe our platform gained followers in our demographic and that the content improved the face of our business. the community management was great and something that was above and beyond my expectations. I was impressed by the quality of the account manager she really put a lot of time and effort into our project.
Social Media Marketing Review from Rebecca Schmidt
We needed Digital marketing and social media content. The goal is to gain more social media presence and brand recognition. I initially provided the basic information about our company and brand for them to come up with a proposal suited to our needs. And then we arranged a meeting to better understand the story of our company and the goals we are aiming for. We have been consistently gaining likes and followers on our Social Media and established our Google Ads. They are very hands-on and have exceptional communication skills. We are very happy with the quality of work there are doing for us.

Lead Generation Review from Armand arton
A game changing collaborationIts rare to find a digital marketing agency that gets the CBI world, but these folks really do. First off, they crafted strategies that really fit with the unique aspects of our business. They also know exactly how to talk to our high-net-worth clients in a way that resonates. But whats been really impressive is how they handled the cultural side of things. Our clients come from all over, and OWLEADSs campaigns are spot on in every market - they get the language and cultural nuances just right.Since teaming up with OWLEADS, weve seen a real boost in quality leads and our ROI is looking better than ever. Theyre transparent, super effective, and just great to work with.

Republic Marketing was referred to us by one of our clients, and from the first conversation, it was clear we were in safe hands. They took the time to understand our business, what sets us apart, and how to reflect that through a modern, professional website. The result speaks for itself. We’ve had brilliant feedback from clients and suppliers, and it genuinely feels like an extension of who we are. The site is clean, easy to navigate, and built to last. We’re now working with them again on our commercial division and wouldn’t hesitate to recommend them.

SEO Review from Dilyana Tabakova
As a blogger, I needed some additional support with my SEO and SixSix marketing helped me boost my website on Google. The team was absolutely spectacular in guiding me towards understanding what SEO is and the impact it could have on my business. For me, working with the company has been more than a business formula put into action. Many thanks to Luke who helped me expand my target reach tremendously!
Small Business Review from Donatas Pilka
Luke at Six Six Marketing did outstanding work for our online marketing, SEO, website updates and social media campaigns! Many of these tasks require both time and knowledge to complete effectively. However, everyday running of a business often spares little time or ability to properly look after our marketing needs. Leaving these tasks in the trusted hands of Six Six Marketing has been a great success and relief, allowing us to focus on other aspects of the business. Many thanks to Luke!
Sue Humphrey's Review Sourced from Google
We've used Six Six Marketing and Luke Chapman for a number of years now. We find him conscientious and effective, and without a doubt our internet presence is far greater than it would have been without Luke's support. Reasonable prices offering great value. I particularly like how we get a full breakdown each month of exactly what tasks he has carried out on our company's behalf. Without this list it would all be a bit of a mystery, but this shows clearly exactly what has been done and how long it's taken. Very receptive to our questions and suggestions but happy to put his own view too. Highly recommended.

I've been working with RCM for over 6 months now, and the experience has been genuinely great. After trying a few agencies in the past, it often felt like they were either too salesy or just not the right fit. RCM has been a refreshing change — they tailor their services to exactly what your brand needs without trying to upsell or overcomplicate things. You can tell they genuinely care about your brand's long-term growth, taking a steady and thoughtful approach. Huge shoutout to my account managers, Chloe and Phil — both are excellent at what they do and a pleasure to work with. Thanks again!

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!
