What our clients say about us
"Zinzo addressed the legacy code affecting our shop's speed performance, while developing some new features. As a result, the performance score already doubled, with more improvements following soon."
Guido Evers
Testa Omega-3
"The custom improvements to our webshop were done professionally, in close cooperation with our technical partner and delivered within 2 weeks. We immediately noticed the results in our analytics: in the first month we measured a 14% conversion rate increase from organic search and +81% increase on paid search."
Ronald Klijsen
Loints of Holland
"The core web vitals changed from 60 (fail) to +80 (pass) following the performance fix to one of our client's Magento webshop. Directly we saw the paid traffic conversions improve by almost 80%."
