Google’s own Jon Mueller was asked about an algorithm update in one of his Google+ Hangouts, he stated that it was not related to a Panda or Penguin refresh, which means it could be some form of new algorithm.
The cherry on the cake was where Google has been sending out warnings to webmasters whose websites were not mobile-friendly and asking them to update their site.
Users suspect the mobile update to be launched around 20th April 2015 so if your website is still not mobile friendly then please wake up and smell the roses and act. It takes very little time for a standard sized website to be converted into a responsive site, making it friendly for all devices.
If you have seen a drop in mobile traffic since the 24th January 2015 then it would be worth checking to see if your website is mobile friendly and if it is not, then act now.
