To check if your site is mobile-friendly, you can examine individual pages with the Mobile-Friendly Test or check the status of your entire site through the Mobile Usability report in Webmaster Tools . If your site’s pages aren’t mobile-friendly, there may be a significant decrease in mobile traffic from Google Search. But have no fear, once your site becomes mobile-friendly , we will automatically re-process (i.e., crawl and index) your pages. You can also expedite the process by using Fetch as Google with Submit to Index , and then your pages can be treated as mobile-friendly in ranking.
