Google Penguin Update
Recently Google announced officially that they are making penguin as a part of their core algorithmic changes.
Now penguin will be no more a separate algorithm like previously it used to be, Penguin is now a real-time and it is more granular.
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 re-crawl and re-index 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.
