Google: Penguin Update 4.0

Google updates Penguin, says it now runs in real time within the core search algorithm

The latest announced release, Penguin 4.0, will also be the last, given its new real-time nature.

After a nearly two year wait, Google’s Penguin algorithm has finally been updated again. It’s the fourth major release, making this Penguin 4.0. It’s also the last release of this type, as Google nowsays Penguin is a real-time signal processed within its core search alorithm.

Penguin goes real-time

enguin is a filter designed to capture sites that are spamming Google’s search results in ways that Google’s regular spamming systems might not detect. Introduced in 2012, it has operated on a periodic basis.

In other words, the Penguin filter would run and catch sites deemed spammy. Those sites would remain penalized even if they improved and changed until the next time the filter ran, which could take months.

The last Penguin update, Penguin 3.0, happened on October 17, 2014. Any sites hit by it have waited nearly two years for the chance to be free.

Those long delays are now to be a thing of the past, according to Google. With this latest release, Penguin becomes real-time. As Google recrawls and reindexes pages — which happens constantly — those pages will be assessed by the Penguin filter. Pages will be caught and/or freed by Penguin as part of this regular process.

Penguin becomes more page-specific, not sitewide only

Google also said this new Penguin algorithm is “more granular.” From its post:

Penguin is now more granular. Penguin now devalues spam by adjusting ranking based on spam signals, rather than affecting ranking of the whole site.

Previously, Penguin was a sitewide penalty. So, does being “more granular” mean that it’s now page-specific? Yes and no, it seems. We asked Google for more clarity about this, and we were told:

It means it affects finer granularity than sites. It does not mean it only affects pages.

Our best interpretation of this statement is that Penguin might impact specific pages on a site, or it might impact sections or wide swaths of a site, while other pages are fine.

Past Penguin updates

For history buffs, here’s the rundown on Penguin updates over time, as well as the impact they’ve had on queries, according to Google:

• Penguin 1.0 on April 24, 2012 (impacting ~3.1% of queries)
• Penguin 1.1 on May 26, 2012 (impacting less than 0.1%)
• Penguin 1.2 on October 5, 2012 (impacting ~0.3% of queries)
• Penguin 2.0 on May 22, 2013 (impacting 2.3% of queries)
• Penguin 2.1 on Oct. 4, 2013 (impacting around 1% of queries)
• Penguin 3.0 on October 17, 2014 (impacting around 1% of queries)
• Penguin 4.0 & real-time on September 23, 2016

Penguin 4.0, Google would not give a specific number of the percentage of queries it impacted, mostly because the update is constantly happening and the percentage will constantly be changing.
