Nick was instrumental in the successful integration of our new CRM system into our website. His technical knowledge and attention to detail were greatly appreciated. The intuitive functionality and visual appeal of our new website that Nick built has been a fantastic improvement of our online presence.

Julie Lewis's Review Sourced from Google
Designing a website is a creative task; finding the right person / company to do this can be complex! Thank goodness I met Nicole! Thanks to her creative ideas, practical insights, years of experience and a mountain of patience and support I now have a website to be proud of. Nicole was, and still is, the best guide when it comes to “all things online”. Her global perspective and local insights are extremely important to individuals and organizations who want to leave a strong digital footprint. I have worked with Nicole for 4 years and continue to do so ; I highly recommend you have a conversation with Nicole to discuss all your online needs.Thank you so much Julie!! XxNicole

Very responsive and supportive. A special shout-out in particular to Elliot for his excellent service provided for ECIS. Elliot not only resolved issues, but also explained his steps and made it easy to understand how I could then implement similar changes.
David Anderson Review from Google
5.0★
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 😊
