At SMX Advanced, Google’s Gary Illyes announced that Google is working toward a continuously running Penguin update. He admitted that Penguin currently runs slowly, but said Google is working to make it update in real time. If that happens, the algorithm will get data that is refreshed all the time. Currently, the data has to be manually refreshed to see any ranking changes for sites impacted by Penguin.
Illyes explained it is hard for Google to do this right now because it requires a lot of reworking of the algorithm. But that is their goal, to make the Penguin algorithm run by itself, without manually refreshing any data. Illyes said this kind of change is months away and didn’t estimate a date for when webmasters can expect this change.
He also said that Google doesn’t see the update Panda ever running continuously, but rather requiring a manual data refresh.
