The United Kingdom's Most Popular Websites - Ranked by Homepage Speed

These numbers were produced using Google PageSpeed Insights. Some websites did not produce data from google and have been indicated with 'no data'. Adult sites were not included. The lightspeed rank was calculated by ranking FCP, FID and time to interactive then adding all of the numbers together for both mobile and desktop. They were then ranked lowest to highest to find which one has the fastest average speeds. The FCP numbers were generated from the top 90th percentile and FID from the top 95th percentile so that websites meet a minimum standard of performance under the most difficult conditions.
