Here's what VWO users from across verticals have to say
What we loved about VWO was its simplicity. The ease of digging into customer insights and running tests with VWO’s drag-and-drop editor was truly seamless.
Ruben Ten Brinke, Marketing Operations Coordinator
VWO is a great tool that lets us test different variations of the homepage on a small sample of visitors. Thanks to VWO, we managed to find out the perfect combination of CTAs on the GetResponse homepage and increase the overall conversion.
Agnieszka Dabrowska, Brand Manager
It was really easy to conduct A/B experiments even for complex cases as we generally encounter in the case of PayU’s checkout products. A double thumbs up from my side for VWO.
Abhinav Chitre, Senior Product Manager
Given we were dealing with a perennial issue of low conversion rates on our eCommerce store, we wanted to bring in someone who has already tackled this successfully. Since we did not have the bandwidth to build a team in-house, we decided to try VWO.
Daniel Kamen, eCommerce Director
Every day my inbox is full of salespeople who promise revenue gains. VWO actually delivers.
Whitney Pye, Vice President, Strategic Initiatives
Prior to working with VWO, we designed our website through intuition, not facts. VWO provided a data-driven approach to analyze user behavior and helped us achieve our target metrics. We now work through data, and not intuition.
Jinuk Lee, Founder
In my role at Warner Music Group, I aim to promote a culture of data-driven creative design. We design, build, and maintain hundreds of artists' websites. VWO's suite of tools helps me quickly and easily find conversion optimization wins that I can standardize across our whole enterprise. I don't like to use the phrase "best practice" unless I can prove it, and my proof is in the data provided by VWO.
Brandon Gentry, Director, User Experience
VWO helped us to conduct experiments and user research, which became the backbone of optimization across our online marketing properties.
Jenny Hughes, Digital Marketing
In our optimization process, VWO has been our key tool to drive BluTV's main goals. Thanks to its easy to use and powerful features, we increased the mobile membership trial conversion rate by more than 40%.
Mustafa Esad Tatlipinar, Optimization Manager (On behalf of BluTV)
