Dat Boi Review from Google
1.0★
Dat Boi's Review Sourced from Google
Unfortunately, my interactions with Farhad at Accuracast have been far from pleasant. Despite working on multiple projects together, the experience has consistently fallen short of expectations. Farhad's attempts to simplify complex procedures were ineffective, leaving me even more confused and frustrated, especially given my limited tech knowledge. It appears that he and the team lack genuine concern for delivering optimal solutions tailored to business needs. Overall, my encounters with Farhad and Accuracast have been disappointing, and I cannot recommend their services based on my experiences.
Sam Pitcher Review from Google

Sam Pitcher's Review Sourced from Google
I've had the pleasure of working with Farhad at Accuracast on a few projects now and each time the experience has been outstanding. Farhad has a knack for breaking down complex procedures into understandable terms, which was invaluable to someone like me with limited tech knowledge. It’s clear that he, along with the team, really cares about finding the best solutions tailored to your business needs.
EUROUT Conference Review from Google
4.0★
EUROUT Conference's Review Sourced from Google
AccuraCast provided a swift, responsive, user-friendly and professional service. Farhad and Luke guided us patiently and efficiently through the process of devising our social media campaign (in the rather compressed timeframe we had given them to do so), and then smoothly project managed the implementation stage. We were especially impressed with how quickly and effectively they stepped in to resolve any technical or other issues that arose as the campaign unfolded, and supported us with last minute requests or changes from our side.

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!

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.

Emily Whitworth's Review Sourced from Google
Hewitt Matthews have been the best developers I have worked with as a marketer. Not only have they maintained and updated our old WordPress website to a high standard, they have also been incredibly responsive, clear, and thorough. Specifically, I have worked a lot with Duncan, who has consistently gone out of his way to create training videos, comprehensive emails, and intuitive suggestions for any question I have had. I would highly recommend their services!

Richard Gray's Review Sourced from Google
Really enjoyed working with Carl, Reece and the rest of the team at Hewitt Matthews. They stepped in to assist when my team was light on resource and capability and smoothly handled the transition for us and our Paid Media account. They've also done a good job with website development projects for me in the past. Wouldn't hesitate to recommend them for any digital project.

We launched the business, starting from scratch with a previously unused .co.uk web domain… WOYA got our site designed, and traffic flowing to it very quickly. They utilised a wide range of techniques, and our business was ranking highly in searches much sooner than expected.

Oliver Read's Review Sourced from Google
We have been working with Woya Digital for several years now and really pleased with the results. They have helped significantly with our SEO, PPC and lead generation, as well as providing additional support and advice on wider topics complimentary to this. We are now able to connect with suitable clients looking for our services, and promote our practice effectively and efficiently. This has led to a significant increase in our new client enquiries as a result. We would very much recommend the services of Steve, Natalie and the team.

SEO Review from Patrick Roden
Fresh Car started using Grant's services for SEO over two years ago, and since then, our reliance on paid media has plummeted, and our marketing profitability has soared as a result of Grant's results. We are a franchise business with over 80 locations, and over the course of these two years, every single one of these locations has consistently ranked in the top spots of Google for our targeted keywords. I couldn't recommend Grant enough.
