Geraint Jones's Review Sourced from Google
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.

Had a pleasure to work with Ethan for a couple months. Having to live in Canada with different time zones, he’s been very good with getting back to me with my inquiries/questions alongside my business partner. I appreciate all the help, Ethan!

Daniel Wilds's Review Sourced from Google
Burniston Marketing Partners are a pleasure to combine with. I've crossed paths with Ethan on multiple occasions over the last 2 years since meeting him. His urgency and attention to detail is inspiring. And to anyone on the verge of taking action with them I'd say to take the time to speak to them, and let the qualities I have listed above shine through.

Working with Ethan from Burniston Marketing Partners has been a great experience. He's reliable, thinks fast, and is always proactive about next steps without needing to be pushed. Would definitely recommend!
