Google Algorithm Update as of August 10th, 2013

Panda Recovery — July 18, 2013

Google confirmed a Panda update, but it was unclear whether this was one of the 10-day rolling updates or something new. The implication was that this was algorithmic and may have “softened” some previous Panda penalties.

Multi-Week Update — June 27, 2013

Google’s Matt Cutts tweeted a reply suggesting a “multi-week” algorithm update between roughly June 12th and “the week after July 4th”. The nature of the update was unclear, but there was massive rankings volatility during that time period, peaking on June 27th (according to MozCast data). It appears that Google may have been testing some changes that were later rolled back.

Panda Dance — June 11, 2013

While not an actual Panda update, Matt Cutts made an important clarification at SMX Advanced, suggesting that Panda was still updating monthly, but each update rolled out over about 10 days. This was not the “everflux” many people had expected after Panda #25.

“Payday Loan” Update — June 11, 2013

Google announced a targeted algorithm update to take on niches with notoriously spammy results, specifically mentioning payday loans and porn. The update was announced on June 11th, but Matt Cutts suggested it would roll out over a 1-2 month period.

Penguin 2.0 (#4) — May 22, 2013

After months of speculation bordering on hype, the 4th Penguin update (dubbed “2.0” by Google) arrived with only moderate impact. The exact nature of the changes were unclear, but some evidence suggested that Penguin 2.0 was more finely targeted to the page level.

Domain Crowding — May 21, 2013

Google released an update to control domain crowding/diversity deep in the SERPs (pages 2+). The timing was unclear, but it seemed to roll out just prior to Penguin 2.0 in the US and possibly the same day internationally.

“Phantom” — May 9, 2013

In the period around May 9th, there were many reports of an algorithm update (also verified by high MozCast activity). The exact nature of this update was unknown, but many sites reported significant traffic loss.

Panda #25 — March 14, 2013

Panda #24 — January 22, 2013

Google announced its first official update of 2013, claiming 1.2% of queries affected. This did not seem related to talk of an update around 1/17-18 (which Google did not confirm).
