Google announced in November 2016 that over the next few months it would change the way it orders the different websites, giving priority to mobile browsing.
Internet is mobile and the figures prove it. According to the report The Information Society in Spain in its 16th edition, 88.3% of Internet users access the Internet through their smartphone , while 78'2% use their computer. It was logical that, if the majority of searches are performed on mobile devices and, if Google refers to the mode in the one the user browses, the search engine ends up making changes to its indexing algorithm.
