Penguin, which was launched in 2012 has become real-time and more granular. In an official Google blogpost, Google said: One specific signal of the algorithms is called Penguin, which was first launched in 2012 and today has an update. After a period of development and testing, we are now rolling out an update to the Penguin algorithm in all languages.
Here the important changes that the webmasters had requested over time:
Penguin is now real-time. Historically, the list of sites affected by Penguin was periodically refreshed at the same time. Once a webmaster considerably improved their site and its presence on the internet, many of Google's algorithms would take that into consideration very fast, but others, like Penguin, needed to be refreshed. With this change, Penguin's data is refreshed in real time, so changes will be visible much faster, typically taking effect shortly after we recrawl and reindex a page. It also means we're not going to comment on future refreshes.
Penguin is now more granular. Penguin now devalues spam by adjusting ranking based on spam signals, rather than affecting ranking of the whole site.Penguin Becomes A Part Of Google Core Algorithm,
