If you want to check whether or not your site is mobile friendly (by Google's standards) go to: https://www.google.com/webmasters/tools/mobile-friendly/ It will be harder and harder to rank higher in SERPs if your site isn't mobile friendly. Not that you guys didn't know that. Just thought I'd share the link, just in case.
