Having a fast website was one of the key ranking factors. And recent Google updates (July 2018) bolster site speed as a key quality signal for both desktop and mobile rankings. This further solidifies speed optimization as a major part of SEO.
But it’s not just about Google rankings, a slow website can affect user experience as well.
A few extra seconds of loading time can have a huge impact on your visitors and sales. Studies show that a 1-5 second delay increases bounce rates by up to 90%. Furthermore, Amazon discovered that a 1 extra second could cost them as much as 1.6 billion dollars a year.
