After a number of webmasters reported ranking shuffles, Google confirmed that a data error had caused some domains to be mistakenly treated as parked domains (and thereby devalued). This was not an intentional algorithm change.

Google rolled out another post-”flux” Panda update, which appeared to be relatively minor. This came just 3 days after the 1-year anniversary of Panda, an unprecedented lifespan for a named update.
Google published a second set of “search quality highlights” at the end of the month, claiming more than 40 changes in February. Notable changes included multiple image-search updates, multiple freshness updates (including phasing out 2 old bits of the algorithm), and a Panda update.
As part of their monthly update, Google mentioned code-name “Venice”. This local update appeared to more aggressively localize organic results and more tightly integrate local search data. The exact roll-out date was unclear.

Google released another round of “search quality highlights” (17 in all). Many related to speed, freshness, and spell-checking, but one major announcement was tighter integration of Panda into the main search index.

Google updated their page layout algorithms to devalue sites with too much ad-space above the “fold”. It was previously suspected that a similar factor was in play in Panda. The update had no official name, although it was referenced as “Top Heavy” by some SEOs.

Google announced a radical shift in personalization – aggressively pushing Google+ social data and user profiles into SERPs. Google also added a new, prominent toggle button to shut off personalization.
