After a nearly tw
o year wait, Google’s Penguin algorithm
has finally been updated again. It’s the fourth major release, making this Penguin 4.0. It’s also the last release of this type, as Google nowsays
Penguin is a real-time signal processed within its core search algorithm.
Penguin is a filter designed to capture sites that are spamming Google’s search results in ways that Google’s regular spamming systems might not detect. Introduced
in 2012, it has operated on a periodic basis.
In other words, the Penguin filter would run and catch sites deemed spammy. Those sites would remain penalized even if they improved and changed until the next time the filter ran, which could take months.
