Chloe Gabbitas-Powls's Review Sourced from Google
I can't praise Ash and Jack enough for their work. I had previously been working with a very poorly designed and functioning website with very low SEO rankings which was extremely frustrating for a new company. Jack designed me a perfect functioning website. I have had many compliments regarding my new look website. My business over the last 6 months has gone from strength to strength with the help and never ending support from Greyzip. Nothing is too much trouble and a pleasure to work with. Thank you guys :-)

Mike Holden's Review Sourced from Google
I am a self employed psychotherapist working in Tipperary, Ireland. I took Andy up on his offer of a free consultation and I’m very glad that I did. After using his software on a two week free trial we met again and with his specialist knowledge he was able to identify and resolve many issues with my website. I find Andy supportive, generous and very easy to work with and am glad to have him for ongoing support. Thanks Andy :)

USN P22 Trust's Review Sourced from Google
I first went to Andy for some advice about my website and was genuinely blown away by how much free, practical guidance he shared without charging a penny. His insight gave me instant clarity on what needed improving and why. I now continue to work with Andy for ongoing hints and tips to develop my website further and I confidently recommend him to anyone who wants more enquiries from their website. He proves his value first and that’s exactly why he’s so easy to trust.

Craig Webb’s SEO training course is just fantastic. Craig manages to explain all about SEO and other tech related issues in simple and concise way and has helped me tremendously in understanding the concept of SEO and its importance in relation to websites. A huge 10 out if 10 for me .Geraint - Rhosydd Bach Holidays.

Liam Carolan's Review Sourced from Google
Craig and his team have been invaluable in keeping my website running smoothly. From ensuring no web pages are broken to indexing pages, creating high-quality blog content, and improving overall site health, they handle everything I don’t have the time (or patience!) to learn.What sets Craig apart is his hospitality background—he truly understands what we, as hosts, are looking to achieve and how crucial direct bookings are for increasing profitability. Because of this, I don’t see Craig’s services as a cost; I see them as an investment in growing my business and securing more direct bookings. His consistency, expertise, and results-driven approach make him a key asset, and I’d thoroughly recommend him.

I have had a working relationship with Glaze Digital for more than 8 years. During that time, they have designed two Shopify stores for my business Lusana Shoe Boutique. We also work with Glaze in terms of our email marketing and google advertising. The service provided is excellent and I would have no hesitation in recommending Glaze Digital as a business partner.
