Overview of Google Panda Iterations (Data Refreshes)

An update of the data basis of the Panda filter is called a “Data Refresh”. Google irregularily deploys iterations of their Panda Update to their search markets.

An iteration is the repeated use of the same process on interim values (data) which were already obtained, as well as gradual or repeated access to a data structure.
