Page Speed Benchmarks

Page speed has a huge impact on user experience. Faster sites have been proven to have lower bounce rates, higher conversion rates, bigger shopping cart sizes, and happier users. In these dashboards, we rank industry-leading websites based on how fast their pages appear to load, from a user’s perspective. For each site, click through to see their detailed test results.
