Web Development Review from Charlotte Conn
Working with Amy and Marcus is an absolute pleasure, they are always so friendly and approachable and are an amazing extension to our team. Right from the start of our website build, Media Lounge have gone out of their way to help with any question I might ask (no matter how ridiculous!), and are always excited to take on new projects with us. Amy has gone above and beyond to bring new ideas to the table and help with our annual planning. I'm so grateful for your support!
Cormac Moylan Owner at CDKeys.com

CRO Review from Cormac Moylan
We (a large international e-Commerce site) wished to increase sales and revenue by improving our conversion rate. Because of the nuances of the market we operated in, It was important we partnered with an agency that understood our business and the relationship we have with our customers. Lauren, Grace, Jackson, and the entire team from Media Lounge understood this. Their tactics and optimisations were carefully tailored on improving the connection between our business and customers. Every opportunity recommended by Media Lounge was aligned to our business goals and demonstrated their expertise, knowledge, and abilities. I was impressed with their in-depth research, solutions, attention to detail, and most importantly; the resulting uplift from their efforts. They challenged us when we needed challenging, they addressed assumptions that previously impacted sales performance, and they introduced positive change for both our customers and our business. We couldn't be happier to have partnered with Media Lounge.

Web Design Review from Anthony
If you are looking for a web design company that is happy to go that extra mile, i would highly recommend Media Lounge. If you are like me and words like 'DNS' 'or CHRON' are another language to you, then you have found the right company, they appreciate not every one grasps the in and outs of how everything works in a website, so everything is explained to you easily and clearly. On top of this they build websites that not only look inspiring, but more importantly covert browsers to buyers at an incredibly impressive rate. Our's jumped from a fairly industry average at 2% to 6% - overnight.

Jack Pleavin's Review Sourced from Google
We moved to RedCore Digital for our SEO support just over 2 months ago after wanting to find a provider with less of an 'agency feel'. SEO is something we've heavily invested in for the past 3 years but we've seen a notable improvement since moving to RedCore.They completed a full audit of our website and met to discuss the plan of action to really get us off the ground. We've seen improvements in our website traffic month on month but most importantly, we've started receiving more enquires through our website. Jay and Dan are highly knowledgeable in their field and have taken our website to the next level.We're looking to grow our business and align ourselves with more clients in the coming years and we feel confident that the team at RedCore are well-placed to support that success. Highly recommend working with the team.

Jelly is an SEO agency built for our time. SEO has changed a lot in the last few years and too many strategies are stuck doing the same things we did 10 or more years ago. Those strategies are no longer fit for purpose. At Jelly we understand how the internet works in the AI age, and we know the most...
