Google to Roll Out Mobile-Specific Algorithm

Collective Measures
October 14, 2016
A Google analyst announced plans to release a separate mobile search index, which will become the primary index used to respond to search queries.

Gary Illyes, a Google webmaster trend analyst, announced that Google plans to release a separate mobile search index which will become the primary index Google will use to respond to search queries. As part of the update, there will be a separate desktop index but Google will not update it as often as the mobile index.


Mobile search rankings in Google will be universally changed. Google will be able to more accurately prioritize how it applies ranking factors by device type, which means the set of factors that rank one result on desktop could be very different from the factors ranking the same keyword on mobile.

There are a lot of unknowns right now, but the existing mobile-specific factors are related to site speed and how the page looks (font sizes and readability, ads above-the-fold, content that does not scale properly).

A mobile-specific algorithm is going to apply Google’s existing ranking factors to desktop content to determine relevance and value. Shorter, more to-the-point content will likely get preference on mobile; video formatting will likely increase in value.


It is unclear as to when Google plans to roll out the new engine but Illyes confirmed it will happen within months.


Improving search result relevance and the search experience for users is always at the core of any organic algorithm update. There are more mobile searches than desktop conducted each year, so Google is adjusting its ranking technology to meet user demands.

The move is also acknowledgement from Google that they know search intent and behavior is very different depending on the user’s device. People have different expectations for search results when they’re on mobile vs. desktop.


Mobile should be a critical part of your organic search strategy, and measuring mobile and desktop engagement is a must for determining organic visibility opportunity and success.
