Benchmark Your Web and Mobile User Experience

Yottaa's CEXi is a compound index that quantifies the desktop and mobile user experience of a web application far more accurately than any single metric. The CEXi combines objective, measurable aspects of performance, such as page load speed from both mobile and desktop simulations, with specific weighting calculations to provide online businesses with an overall performance score that simulates the actual feeling, positive or negative, of using their web applications for a modern, cross-device user.

The Customer Experience Index focuses on three aspects of web performance: speed, parity of experience (across devices), and how well a site is optimized in relation to its complexity.
