Search Master: New Mobile Index Will Soon be the Primary Index at Google
Google may not have a single index for mobile and desktop users any longer, and everything you know about SEO could soon change.
It has been reported from Pubcon this week that Google may, in fact, release an entirely separate mobile search index. And what's more, it could prove to be the primary index that the search engine uses to respond to the queries it receives.
Mobile and desktop users obviously seek out different kinds of information so it ultimately makes a great deal sense for Google to provide two entirely separate experiences. No specific information was provided by Google about how a mobile-centric index would differ from a desktop-centric index, with the exception that the desktop index will not be as up to date (assuming that means less "fresh" content and more "evergreen" which could mean recency trumps authority in some regard). Only as the index is released, however, will SEO's and all 'Net professionals understand the role that design, speed, and links/trust play in ranking so stay tuned.
The news broke in a keynote address from Google's webmaster trends analyst Gary Illyes who indicated that it could happen within just a few months. Google is unlikely, of course, to roll out any significant adjustments to the methods and processes it uses to rank sites before the 2016 holiday, so that puts the earliest possibility of its occurrence in early January 2017 (but will more likely be in February).
