eCommerce Development Review from Tanner Cibula
Magnetos team helped us create a highly functional and visually appealing website using WordPress. They understood our need for a text-focused layout to clearly explain our services, and they brought that vision to life. The design is user-friendly, making it easy for visitors to navigate and learn more about what we offer.Since the launch, Magneto has been handling all our hosting and maintenance needs, ensuring the site remains secure and up-to-date. They also provide expert guidance whenever we want to make significant updates. Their ongoing support and dedication have made them an essential partner for our online presence.

Working with Magneto was a fantastic experience from start to finish. They built our website from the ground up using WordPress, ensuring it was easy to navigate and content-focused so we could effectively showcase our services. The team was highly responsive to our needs and made sure the design reflected our vision clearly.After the launch, Magneto has been providing ongoing hosting and maintenance, which gives us peace of mind knowing everything is running smoothly. They're also our go-to consultants whenever we need to make significant updates or changes to the site. Their expertise and reliable support have made them an invaluable partner, and we highly recommend them.

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)

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 Review from Google

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.
