Advances in Internet technology like widespread broadband access have made the Web much faster over the years, and now it's mobile's turn. Google is now recommending webmasters try to get their pages to load in just one second on mobile devices as a way to keep people from leaving due to waiting too long.
Google's PageSpeed Insights tool can examine websites to see what kinds of issues they have when it comes to webpage load times. Mobile websites take an average of seven seconds to load, according to a Google Analytics study, and other research has shown that is simply too long for people to wait. On mobile devices, that seven seconds can seem like an eternity, especially when people are used to such fast load times on their broadband networks.
Of course, people are using their mobile devices quite often on those high speed wireless networks as well, but when it comes to 3G or 4G mobile traffic, speeds plummet. That's where Google's recommendationscould come in handy. There isn't much we can do to speed up telecommunications networks, but websites can in fact make some changes to get faster.
Prioritize the Critical Rendering Path
Humans perceive anything that happens in less than 100 milliseconds as instant. We can perceive delays of between 100 and 300 milliseconds, so by the time we get to one second, people start leaving websites that haven't loaded. When we're talking about seven second load times on mobile devices, the problem becomes clear.
To speed up mobile websites, Google recommends a few best practices in regards to what it calls the critical rendering path. This is the set of steps it takes for a mobile website to display on a device. It starts with so called above the fold HTML, CSS and JS. Servers must render the response in less than 200 ms, the number of redirects should be minimized, and the number of roundtrips to first render should be minimized, Google recommends.

Speeding up websites also helps with SEO ranking, another good incentive. As LTE networks roll out around the world, telecommunications networks should speed up, but they may never catch up to broadband speeds. Those websites who want to offer the best customer experiences should indeed do what they can to speed up page load times, and the PageSpeed Insights tool looks like a decent place to start.
