Turning browsers into buyers
Does more traffic = more sales?
Many companies are accustomed to this way of thinking. It’s not wrong, but it is inefficient and expensive. At Proof3, we’re all about getting your website visitors to take the actions you want them to take. Because it doesn’t matter how many thousands of people visit your website if they do nothing when they get there—it’s a lost opportunity. When you adopt a user-first CRO approach, you get more value from the visitors you already have and the ones you pay for, and more value from your Magento platform.
The process of CRO is instrumental in helping you understand your users—both in theory and in practice. We discover what engages them and what doesn’t. By removing the guesswork, we design an experience centred around their needs within the native framework. After that, we test everything continuously: every button, banner, CTA, image, and more. The more we test, the more we learn, and the quicker you start seeing consistent successes because data drives your decisions. We take a full-service approach to optimise every aspect for the best results.
If you want different results you have to try different approaches and welcome new ideas. That’s what leads to real innovation.
