Panda Core Algorithm Incorporation

Google confirmed that Panda had been incorporated into the core Google algorithm, evidently as part of the slow Panda 4.2 rollout. In other words, Panda was no longer a filter applied to the Google algorithm after it does its work, but is incorporated as another of its core ranking signals. It has been clarified, however, that this doesn’t mean the Panda classifier acts in real time.

RankBrain

Though it had been in testing since April 2015, Google officially introduced RankBrain on this date. RankBrain is a machine learning algorithm that filters search results to help give users a best answer to their query. Initially, RankBrain was used for about 15 percent of queries (mainly new queries Google had never seen before), but now it is involved in almost every query entered into Google. RankBrain has been called the third most important ranking signal.

Panda Update 4.2 (#28)

Google announced a Panda refresh that would take months to roll out and impact 2 to 3 percent of English queries. Due to the slow nature of the rollout, it’s unclear how substantial the impact was or precisely when it occurred. It was the final confirmed Panda update.

Penguin Update 3.0

Though named like a major update, this was actually another data refresh of Google’s Penguin algorithm. Penguin 3.0 allowed those impacted by previous updates to emerge and recover, while many others who had continued to utilize spammy link practices, and had escaped the radar of the previous updates, saw an impact. The update took about three days to fully rollout and impacted less than 1 percent of English search queries.

Hummingbird Update

The Hummingbird update was a major overhaul to Google’s core search technology. Google needed a way to better understand and return the most relevant results to more complex queries as a result of the growth of conversational search (i.e., voice search). Google said the new algorithm affected about 90 percent of searches worldwide. Although this update was announced on this date, it actually started rolling out in August 2013.

Payday Loan Update

Google Payday Loans algorithm update targeted spammy queries mostly associated with shady industries (including super high interest loans and payday loans, porn, casinos, debt consolidation, and pharmaceuticals). It took about 1-2 months to fully rollout and impacted about 0.3 percent of U.S. queries.

Panda Update (#25)

This update was not confirmed by Google though tools suggest it occurred on roughly this day.  Google’s Matt Cutts seemed to suggest that this would be the final update before Panda would be incorporated directly into the core Google algorithm. Instead, however, Panda data refreshes started rolling out monthly over a 10-day period, without any further confirmation from Google.

Panda Update 3.6 (#14)

April 24, 2012

Penguin Update

A long-anticipated “over-optimization” penalty finally arrived on this day. Google announced the launch of a (then unnamed) algorithm change meant to downrank websites engaging in aggressive webspam (e.g., keyword stuffing, unnatural linking) that violated Google’s Webmaster Guidelines. Google said this update would impact 3.1 percent of English queries. Just two days later, we learned the name of the algorithm: Penguin.

Vince Update

Google’s Vince update was a quick, noticeable change in broad-level, competitive keyword terms to favor first page rankings for big brand domains vs. previously ranking sites (typically less authoritative sites, affiliate sites, and sites that had won this coveted visibility purely through SEO efforts).

Big Daddy Update

Big Daddy (or Bigdaddy) was a gradual update to Google’s infrastructure that began rolling out in December 2005 and was completed in March 2006. This update changed how Google handled technical issues such as URL canonicalization and redirects. Some websites didn’t make it into the new Big Daddy data centers, typically due to unnatural linking (e.g., excessive reciprocal linking, linking to spammy neighborhoods, paid links).

Jagger was an update in three phases (Jagger 1, Jagger 2, and Jagger 3) that began with a number of backlink-focused updates in early September meant to crack down on unnatural link building, paid links, and other types of spam. The second phase of Jagger had the most noticable impact in October. The final phase was completed near the end of November.

Florida Update

Google’s Florida Update signaled a new era of SEO. Websites (including retailers who relied on affiliates to drive traffic) using spammy tactics of the previous decade (e.g., keyword stuffing, using multiple sites under the same brand, invisible text, and hidden links) to rank for high-commercial keywords saw their rankings wiped out right before the lucrative holiday season.
