Author’s update on April 22: It’s better late than never! Giving Google what Google wants is like paying tax. If you don’t do it by the due date, you will pay a penalty, but it still has to be done and the penalty will stop as soon as you do it. So it’s time to make your website mobile-friendly, it only takes a few days!
Google recently made an announcement that as of April 21, 2015, they will favor websites that are mobile-friendly. Google has been testing this idea for some time now, and they have now made it official policy. Essentially, Google will determine whether your website is mobile friendly or not; if it is not mobile-friendly, for mobile searches, your website will show up after those that are mobile-friendly.
