Since 2018 Google has made the loading speed (website speed or page speed) a decisive ranking factor. Since then, it has been essential to check and, if necessary, optimize the loading time of your own website to ensure that it can be found. Mobile users with smartphones or tablets don’t like slow websites on the go. Although high-speed Internet access for mobile devices is already available in conurbations, the Internet connection via smartphone is usually considerably slower than in stationary WLAN. Optimization for fast loading times is therefore particularly important. In any case, the loading time of the web page should be less than 3 seconds, ideally 1.5 seconds.
