Google has announced that July 2018 onwards PageSpeed tool will be used as a factor to rank pages in mobile search. Since 2010, speed is a factor that determines page rankings for desktop searches.
However, now it will be extended to mobile searches, as well.
This “Speed Update” will only target the pages that render the slowest loading experience to the users, as of now. This means, whether the page is affected by this algorithm update or not, wouldn’t be easy to determine.
