While analyzing frame-by-frame page loads of the top 100 retail websites (for our most recent State of the Union for ecommerce web performance), I discovered that a surprising number of sites were making the same three design/usability mistakes over and over. These mistakes had a huge impact on how the pages rendered, and ultimately on the end user experience.

This week at Radware, we’ve released our annual mobile performance report, the 2013 State of the Union for Mobile Ecommerce Performance. Every year, we study the performance of top online retailers to see how they measure up against user expectations. Today I want to share a poster version of the infographics we created to accompany the report.
