According to Instant America's infographic 50% of mobile users abandon a page if it does not load within 10 seconds and 3 out of 5 will not return back to that page. Also it shows the increasing trend of choosing mobile over tablets, laptops, or desktops to access the interwebs.
Page loading time is obviously an important part of any website’s user experience. And many times we’ll let it slide to accommodate better aesthetic design, new nifty functionality or to add more content to web pages. Unfortunately, website visitors tend to care more about speed than all the bells and whistles we want to add to our websites. Additionally, page loading time is becoming a more important factor when it comes to search engine rankings.
