Google announces top mobile page speed tips

How to optimise your mobile site speed

Google has announced new guidelines and updated its PageSpeed Insights tool to help webmasters improve the loading time of mobile pages.

Research from the Nielsen Norman Group shows that user flow is interrupted if a page takes longer than one second to load.

Google has suggested that by presenting above-the-fold content in one second or less, this would give the rest of the page time to load and also allow the user to move seamlessly between pages.

Google has outlined how webmasters can improve mobile site speed by following the best practices outlined in their new guidelines:

  • Server must rend the response (<200ms)
  • Number of redirects should be reduced
  • Number of roundtrips to first render should be reduced
  • Don't external block JavaScript and CSS in the above-the-fold content
  • Set aside time for browser rendering and layout (200ms)
  • Optimise JavaScript execution and rendering time

In a Google blog post posted by Software Engineer Bryan McQuade and Webmaster Trends Analyst Pierre Far, it said: "Our guidelines focus on rendering some content, known as the above-the-fold content, to users in one second (or less!) while the rest of the page continues to load and render in the background."

Test your optimised mobiles with the updated PageSpeed Insights Tool

Google has also chosen to update its PageSpeed Insights tool while providing webmasters with new guidelines on the optimisation of mobile page speed.

The tool allows you to see a visual representation of your site on a desktop and mobile. It also provides optimisation tips on how to improve your page speed on both mobile and desktop.

Natalie Booth, head of search at theEword, said: "Speed is a factor in Google's algorithm, so it is important for webmasters to optimise their page speed. Having a good mobile site speed is also highly beneficial to the user, as it ensures that they can move easily around a site without becoming distracted or frustrated."
