Overview of Google Penguin Update iterations (data-refreshes)

Anytime there is an update to the data base on which the Penguin Update runs, it is called a “data refresh”. Google rolls out new iterations of their Penguin Updates at different times to the different search-markets.

An iteration is the continued usage of the same process on already obtained (intermediate) data, as well as the step by step or continued access to a specific data-structure.
