Over the past few years, we have been working with WebFX on various ongoing projects surrounding our websites. They have taken our SEO from non-existent to one of the best websites throughout our time working together. They provide easy-to-understand, solutions-oriented objectives for us and can work cohesively with us to achieve those goals. I like their ability to work hand-in-hand with you and keep you informed in such an organized manner with progress reports.

Stuart Armstrong's Review Sourced from Google
Zedcomms have handled my media work for several years now. They work closely with me and have gone the extra mile to understand my business. This has resulted in a vastly increased media presence, more sales (particularly from outside the UK), and guess what? When someone searches online for companies in my industry, my company is the first name they see! I am delighted and cannot recommend Zedcomms too highly
Stuart Armstrong's Review Sourced from Google
Zedcomms have handled my media work for several years now and I have certainly noticed, and am delighted with, the increased online traffic by way of sales from all over the world in that period. I find Zedcomms to be a friendly and approachable company to deal with and experts in their field. I recommend them very highly.

Julie Bailey's Review Sourced from Google
Solmaz picked up my marketing after I had a few awful experiences with other agencies that charged me a fortune and constantly let me down.She listened to my goals, strategised and managed my Facebook, Instagram and TikTok platforms. Before Leah took this on, I had been trying to manage things myself and run the business at the same time.With this task off my list I was free to take on more clients or have more "me" time.Highly recommend you give Solmaz Marketing a try.

Indigoextra Reviews & Testimonials
Angie Alexandra's Review Sourced from Google
I've been delighted with the attractive web and logo designs and their knowledge of SEO. Whenever I've had a question, I've always received a thorough no jargon answer and I'm delighted with how many enquiries come from the sites. I appreciate their honesty, kindness, and dedication to ensuring I'm a satisfied client.I first hired Indigoextra more than ten years ago to create a website offering my services as an interfaith wedding celebrant. Over the years Indigoextra have created two further fabulous websites for me, as well as upgrading my initial site to make it mobile friendly. They have also completed an SEO campaign for the group website scottishweddingceremony.co.uk for which me and my colleagues now rank on the first page of Google for 'Scottish Wedding', which we are all delighted with.The first website, gettingmarriedinscotland.org included a logo design, Drupal web design and SEO. Since then, they have upgraded the site and created Scottish Wedding Ceremony which now provides details of 20 different interfaith ministers in Scotland.They created an interface where ministers can login and add their own content and photos, helped write content for ministers following an online chat with them where this was required and optimised the site for several keywords. They also created a dedicated same sex LGBTQIA+ wedding website site for me echoing the design of the first wedding website.Both GettingmarriedinScotland and Scottishweddingceremony websites now rank on the first page for a range of target keywords and form my main source of enquiries. The ministers featured on Scottish Wedding Ceremony nearly always renew, which indicates they are also happy with both the service and the number of enquiries they receive.
Francesca Haack's Review Sourced from Google
Martin and the team at Indigoextra have been amazing. After working with multiple SEO agencies over the past 20 years, I can confidently say they are the most friendly, knowledgeable, helpful (and amazingly also least expensive!) of all the agencies we've tried. Our rankings have increased steadily since we started with them, and Martin checks the website every month for anything we should improve on-page. Absolutely recommend!
Alison Hosking's Review Sourced from Google
Indigoextra listened to my ideas and needs and designed a logo, website navigation/functionality to suit my various areas of my business. They helped me with content to include targeted keywords based on their research for what my potential customers would have searched for. They built links and manage the SEO for my site.I have a website that ranks first on the first page of Google for all four areas of my business in my town and county. WellBeingOne has grown from a fledging venture at the first date that the website went live to a succsesful business. My Chi Kung classes are full and my health therapy clinic has a constant stream of new clients discovering me from the website.They have continued to respond rapidly to any changes or additions that have become necessary with design, CMS and SEO. New therapy areas that I have trained in over the years have been built into the website and have quickly ranked highly on the first page and today rank first on the first page.I am able to relax and get on with the practical delivery of my business knowing that they will take care of the marketing. They are also extremely approachable and able to explain in clear non jargon how the website and SEO work.
