Update July 9, 2018: The Speed Update is now rolling out for all users.
People want to be able to find answers to their questions as fast as possible — studies show that people really care about the speed of a page. Although speed has been used in ranking for some time, that signal was focused on desktop searches. Today we’re announcing that starting in July 2018, page speed will be a ranking factor for mobile searches.
The “Speed Update,” as we’re calling it, will only affect pages that deliver the slowest experience to users and will only affect a small percentage of queries. It applies the same standard to all pages, regardless of the technology used to build the page. The intent of the search query is still a very strong signal, so a slow page may still rank highly if it has great, relevant content.
We encourage developers to think broadly about how performance affects a user’s experience of their page and to consider a variety of user experience metrics. Although there is no tool that directly indicates whether a page is affected by this new ranking factor, here are some resources that can be used to evaluate a page’s performance.
- Chrome User Experience Report, a public dataset of key user experience metrics for popular destinations on the web, as experienced by Chrome users under real-world conditions
- Lighthouse, an automated tool and a part of Chrome Developer Tools for auditing the quality (performance, accessibility, and more) of web pages
- PageSpeed Insights, a tool that indicates how well a page performs on the Chrome UX Report and suggests performance optimizations
