google-logo-874x288Soon, Google’s mobile-friendly algorithm is launching and it’s been found that it runs in real-time on a page-by-page basis already.  Gary Illyes has said that factors like page-speed signals for ranking are based not on the mobile version, but on the desktop version.

John Mueller said that there are still many desktop signals used for mobile-rankings back in November, which includes page-speed.

Even though this continues to be true today, Google is still experimenting with breaking out of some of those factors on a mobile versus desktop basis.  It can make sense in some cases, such as with the page-speed algorithm, the top heavy algorithm, and other algorithms that use the construction of the pages themselves.  But for others, like Penguin and Panda, it wouldn’t make as much sense to break them out when it comes to the mobile vs desktop basis.
