Google Algorithm 2012 Timeline – History.

This is purely a reference page with Google Algorithm 2012 timeline of their respective updates.

 

Google Algorithm 2012
Panda #23 — December 21, 2012

Right before the Christmas holiday, Google rolled out another Panda update. They officially called it a “refresh”, impacting 1.3% of English queries. This was a slightly higher impact than Pandas #21 and #22.

Confirmed: A Panda Refresh, Version #23 (SER)







August/September 65-Pack — October 4, 2012

Google published their monthly (bi-monthly?) list of search highlights. The 65 updates for August and September included 7-result SERPs, Knowledge Graph expansion, updates to how “page quality” is calculated, and changes to how local results are determined.

Google Algorithm 2012
Panda 3.9 (#17) — July 24, 2012

A month after Panda 3.8, Google rolled out a new Panda update. Rankings fluctuated for 5-6 days, although no single day was high enough to stand out. Google claimed ~1% of queries were impacted.

Google Algorithm 2012
Penguin 1.1 (#2) — May 25, 2012

Google rolled out its first targeted data update after the “Penguin” algorithm update. This confirmed that Penguin data was being processed outside of the main search index, much like Panda data.

Google Algorithm 2012
Panda 3.6 (#14) — April 27, 2012

Barely a week after Panda 3.5, Google rolled out yet another Panda data update. The implications of this update were unclear, and it seemed that the impact was relatively small.

Google Algorithm 2012
Penguin — April 24, 2012

After weeks of speculation about an “Over-optimization penalty”, Google finally rolled out the “Webspam Update”, which was soon after dubbed “Penguin.” Penguin adjusted a number of spam factors, including keyword stuffing, and impacted an estimated 3.1% of English queries.

Google Algorithm 2012
Panda 3.5 (#13) — April 19, 2012

In the middle of a busy week for the algorthim, Google quietly rolled out a Panda data update. A mix of changes made the impact difficult to measure, but this appears to have been a fairly routine update with minimal impact.

Google Algorithm 2012
Panda 3.4 (#12) — March 23, 2012

Google announced another Panda update, this time via Twitter as the update was rolling out. Their public statements estimated that Panda 3.4 impacted about 1.6% of search results.

Search Quality Video — March 12, 2012

This wasn’t an algorithm update, but Google published a rare peek into a search quality meeting. For anyone interested in the algorithm, the video provides a lot of context to both Google’s process and their priorities. It’s also a chance to see Amit Singhal in action.

February 40-Pack (2) — February 27, 2012

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.

Panda 3.3 (#11) — February 27, 2012

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.
