On Monday Google Google announced the roll-out of the “mobile-first” indexing of the web. In 2016, Google first elaborated its plan to change the manner in which its search index functions, explaining how its search algorithms would eventually be shifted for using the mobile version of a website’s content for indexing its pages.
Google will start the second wave of expanding mobile-first indexing to a larger set of websites. Google’s Takeaki Kanaya tweeted that it seems that the notifications are a part of mobile-first indexing. In December 2017, Google stated that it had started to transition a small number of sites to mobile-first indexing. However, it declined to state which properties had made the transition.
