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.

Peter Nicholls's Review Sourced from Google
West Midlands Growth Company worked with Squibble and SHC on a time-sensitive, high-impact international marketing campaign to promote the DIATOMIC CleanTech Hub under the West Midlands’ Global Growth Programme, and the results were great.From day one both agencies demonstrated a deep understanding of the brief and a shared commitment to delivering not just on outputs, but on outcomes.They delivered an integrated campaign that was data-led, responsive, and agile. The end product featured compelling assets, tailored content for international markets, and a fab digital user experience. Their LinkedIn and retargeting strategies were especially effective in generating leads, and their reporting kept us aligned throughout.Thanks to Squibble and SHC, we achieved all our KPIs and helped enhance the region's reputation as a prime destination for innovation and investment.Highly recommended for any organisation looking to partner with smart, responsive, and regionally aware marketing experts.
Lucy, Nordic Hides And Skins's Review Sourced from Google
Fantastic service from Kim and her team at Squibble LTD. We worked together at fast pace to get the new website up and running in time for our busy season which we managed to achieve. Having had lots of technical issues with our existing site it was fascinating to learn from the experts how a website should be built, hosted and managed properly. I would recommend Squibble to any business big or small. During lockdown 3- if you are looking to make improvements to your existing website I would strongly advise to go for it! Our new website has increased our sales by at least 30% since November. Lucy, (Business Owner of Nordic Hides And Skins)

SEO Review from Joe Martin-Bindley
SEO work is second to none. Our google rankings and online presence have never been higher and this is true testament to the team at Quirky Digital.
SPF Private Clients's Review Sourced from Google
We have had a great experience working with Quirky Digital for over 12 months. They helped analyse and put in place a strong SEO strategy in a very competitive financial services sector. Their approach helped us to shift our website presence in a way we couldn't do before.The team there is proactive, transparent and a joy to deal with, led by Liam who personally helped so much to get our activity off the ground. If you are looking for an agency that is willing to understand your business, communicate things clearly, and back it up with quality deliverables then Quirky are the ideal choice.
Jade Monaghan's Review Sourced from Google
We have been working with Quirky since July 25, in this time we have found the whole team to be personable and really committed to understanding our business model, and aims when it comes to what we wanted for our SEO campaign. We came into this process with very limited knowledge of SEO and Sean, Riley, Beth and the team have guided us every step of the way with their expert knowledge. They have become much more than an SEO agency and a trusted partner in getting our business exposure and achieving our short and long term business goals. We would highly recommend their services.

Barri has a great understanding of marketing strategy and social media. I really valued his insights, particularly around using social platforms to generate leads, which led to more traffic and enquiries through my website. He also helped me set up analytics tools, which have given me a clearer view of what’s working in my marketing. I appreciated how responsive he was whenever I needed to talk something through, and he’s a genuinely nice guy who knows his stuff.

We have been working with Grapevine Ads across a variety of projects, and the results have been absolutely fantastic. They have handled everything from our social media campaigns and creative assets to full-scale TV and video production, and their attention to detail is second to none.Their team completely understands how to balance compelling, high-quality creative work with practical results. The social media assets they produced were incredibly engaging, and the quality of their video production for our TV campaign was exceptional—delivering beautiful, dignified visuals that perfectly hit the brief.Grapevine Ads are responsive, highly professional, and an absolute pleasure to collaborate with. If you are looking for an agency that can seamlessly manage both digital assets and traditional broadcast media while keeping your brand identity intact, I cannot recommend them highly enough.
FD Recruit's Review Sourced from Google
We've used Grapevine for over 2 years now and they've been fantastic for us. They manage our PPC campaigns, which are quite complex. We have monthly meetings (weekly to start with) and set action points to keep improving.I assumed they'd set up our ads and then sit back and do little for their monthly fee. That's not the case at all. Every month they come with suggestions and improvements, with very little work needed from our side. They repay their monthly fee many times over.I previously managed our ads myself, but it had become a science in itself. Grapevine saves me dozens of hours each month staying on top of all the continual changes. Using them is a no-brainer.
Joshua F's Review Sourced from Google
We've worked with Grapevine Ads for a number of years and they've been instrumental in improving both our tracking and advertising performance.The team helped us implement accurate online and offline conversion tracking, giving us a much clearer picture of which campaigns were actually driving revenue rather than just leads. Their data expertise has made a huge difference to how we measure success and optimise our marketing.They also manage our Google Ads and Meta campaigns brilliantly, constantly testing, refining and finding new ways to improve performance. Communication is excellent, reporting is clear, and they genuinely feel like an extension of our team.If you're looking for a PPC agency that really understands data, tracking, Google Ads and Meta, I wouldn't hesitate to recommend Grapevine Ads.
