Technical & Business Web Performance Tips for Super Bowl Ad Landing Pages

Two days before the Super Bowl people are not only betting on the winner, but also on the best commercial. Will the millions of dollars spent really pay off for the advertisers? We took a closer look at the Super Bowl Ad landing pages for these Super Bowl Ads. Our synthetic monitoring showed huge differences ranking from 1.4 to 10s+ load time. If these pages are already slow prior to the big day, we wonder how they will do on Sunday and if there is anything that can be done to speed things up. With this blog we hope to give a wake-up signal to some of these companies. They need ... (more)
