Google’s new mobile ranking algorithm that is going to be released on 21 April 2015 won’t affect searches that are made on tablet computers. It also won’t impact searches from regular desktop computers.
In a tweet, Google confirmed that the new algorithm will only impact searches done on smartphones:
