In early August Google's speed expert Ilya Grigorik announced :
New PageSpeed Insights (with "mobile first" criteria) is now live! [plus.google.com...]
Page Speed Insights measures the performance of a page for mobile devices and desktop devices. It fetches the url twice, once with a mobile user-agent, and once with a desktop-user agent.
The PageSpeed Score ranges from 0 to 100 points. A higher score is better and a score of 85 or above indicates that the page is performing well. Please note that PageSpeed Insights is being continually improved and so the score will change as we add new rules or improve our analysis.
You can test your website and others here : [developers.google.com...]
What's your view on speed being a ranking factor? Have you seen evidence that it is?
