Google announced they will be increasing the mobile friendly ranking factor in the upcoming period. This increase is expected to happen at the beginning of May. This will not do any harm to already mobile friendly sites, as they can use the mobile friendly testing tool to see if their pages are prepared for these changes. It’s important to underline that, if you have a high-quality content, it will rank high even when it is not mobile friendly. Google suggests using the Mobile-Friendly Test and the Webmaster Mobile Guide as support with your mobile-friendly site and a way to improve your mobile site.
