This iteration of Panda is likely 3.9.2 (not 4.0) given the minor effect Google said it will have on search queries. More than anything, the move is likely a data refresh or slight adjustment to the recently unveiled 3.9.1. In fact, Matt Cutts has suggested another major Panda update might not be in the cards for Google.
Brafton reported recently that Penguin updates are expected to be the more aggressive changes from Google for the remainder of 2012 and moving forward. Panda changes have been increasingly small this year, with Tuesday’s update being the smallest. As such, SEO strategies have not been impacted too drastically around these updates in 2012.
Many have anticipated the release of Panda 4.0 at some point, especially after Panda 3.9 hit the web on July 24. However, the two most recent Panda updates have altered search rankings too aggressively – and Penguin 2.0 is the one to watch. Cutts indicated the next Penguin iteration might shake up SEO.
Beyond it’s quality algorithms, Google recently announced a pair of algorithms that some marketers could benefit from. Amit Singhal detailed the use of copyright complaints against a given site as a ranking signal, while Matt Cutts said last week that a slight algorithm change rolled out aimed at offering more domain diversity within SERPs.
