Mobile friendly is a new lession of 2016 seo, athought many seoers are aware of this but few of them can make them well, I just know there must be a clean page apperance and faster speed than normal one, other tips I still keep on learning..
Mobile ranking has become one of the important factors, which has affected the rankings worldwide. A site can be called mobile friendly if it fulfills the following : * Genuine and well-presented content on mobiles * Eliminates the need of resizing (or Zooming) the content * Easily readable on small screens * Easily navigable * should be clear to google.
