Googler Says In some Cases Penguin Algorithm May Not Just Ignore Links, It May Target Whole Site
https://www.seroundtable.comJohn Mueller of Google was asked at the 37:06 mark “Is the penguin penalty still relevant at all or are less relevant/spammy/toxic backlinks more or less ignored by the ranking algorithm these days?”
John replied saying that in most cases, Google will just ignore the links but in some cases, where there is a clear pattern of spammy and manipulative links by the site, Penguin may decide to simply distrust the whole site.
I think that is a good thing.
