Still experimenting. No set timeline, but definitely more than a few weeks
At the stage of preparation for this change, it is very important to copy the content that you want to rank, from a desktop website to mobile.
Kristine Schachinger:
Very important! Copy over content you want to rank for to mobile site (from Desktop)
In the transition to mobile-first indexing, the concept of the page speed will be rethinking, but how exactly not said.
Kristine Schachinger:
Google hasv to reinvent the concept of page speed when going to mobile first indexing.
In addition, after the launch of the new index will increase the role of the site map.
Kristine Schachinger:
Links are the main source of discovery currently. Hard on mobile. Sitemaps will become more important.
Google began testing mobile-first index in November 2016. This means that in the near future, search algorithms will be primarily to evaluate the relevance of the mobile version of the page, and in its absence – the desktop.
At least at first, Google will not measure the speed of loading the mobile pages and to take that factor into consideration in ranking.
If the site may have problems after switching to a new type of indexing, Google will warn about it by Search Console.
