Enchanted Painting Decorating's Review Sourced from Google
I recently hired Mr Digital to create a website for my painting and decorating business using Webflow, and I couldn't be happier with the results. They were incredibly helpful and explained everything clearly throughout the entire process. Communication was excellent, and they made sure I was kept in the loop at every stage. The website looks absolutely fabulous—exactly how I envisioned it. Best of all, they delivered the final product in under a month. Highly recommend!

We had an excellent experience working with Mr Digital on the development of our website - The Green Rooms using Webflow. The team was professional, responsive, and ensured the site design was both visually appealing and functional. Webflow's platform allowed for smooth customization, and the final product perfectly reflects our brand's identity. We appreciate the team's attention to detail and their seamless collaboration throughout the project. Highly recommended for anyone seeking a well-designed and efficient website

David Anderson Review from Google

David Anderson's Review Sourced from Google
We recently commissioned LinkDigital to renew our website and we honestly could not be happier with the end result! In this day and age, lots of marketing and website development companies look the same, and are full of promises so it always feels like a bit of a gamble when you go into contract with one of them, but from the get go we knew from the amount of time and effort the team put into our enquiry that this was a very professional and hard working team. Jack initially handled our enquiry, asked lots of questions of what we wanted and seemed genuinely interested in our business and goals, and he even applied a promotional discount to our website price (which he allowed us to finance over 3 separate payments) before handing us over to the team responsible for building and developing the site, which is where Melissa came in; Melissa was absolutely fantastic and showed the patience of a saint as we added to the site, tweaked things and changed everything from colours right down to text. The site just got better and better as Melissa continued to add various details from photos to links and technical data. We are just absolutely thrilled with the finished article and it is clear to see the amount of time and effort which has went into the site. I would simply finish by saying: if you want a cheap and cheerful website which will be thrown together in a few days, you probably don’t want to use LinkDigital as they take care and time to fully assemble a proper website, which requires input from you the client and lots of information sharing, but once the effort has been put in, you will not be disappointed. Don’t have any doubts, if you employ the services of LinkDigital, you will get a quality product if you decide to go with them, they really care about the quality of what they build as it is essentially their advert for what they create, and their prices are fair when you consider the quality of the product. We would give them 6 stars if we could 😊

I have been scammed by a copycat Scammer pretending to be this company in a work from home scam. I spoke with Paul the CEO who gave me chapter and verse on who these scammers are and what he has had to do about. I am more than happy to place on record that my problems have nothing to do with Paul's company and he has been more than helpful in providing information that will help me recover my lost funds.

I had a great conversation with Duray about SEO. He’s clearly very knowledgeable and took the time to explain how search engine optimization works in a way that was easy to understand, even for someone without a technical background. He was patient, thorough, and happy to answer all my questions.Beyond his expertise, he’s also a genuinely nice person to deal with - professional, approachable, and honest in his advice!
