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.

We have been using VWO for almost 4 years now and the software still surprises us. It is very easy to work with and support is always available for help in case of development challenges. The extra features like heatmaps, session recordings and the surveys help us to easily monitor the entire CRO process and connect our qualitative insights with A/B tests.

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.

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.

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.
