A website speed test evaluates the speed and performance of your website on real browsers and devices to give you an accurate mobile and desktop speed score. This speed score is helpful in benchmarking your website speed against industry standard and competition, and also to understand how your site can be improved.
Each time you run a site speed test on SpeedLab, you will get an accurate mobile and desktop speed score based on your page load time, as well as the First Contentful Paint (FCP), and Speed Index. This will range from 0-100 and based on your score, which will indicate if your site speed is poor, moderate or good.
