Google’s algorithm relies on more than 200 unique signals that makes
it possible to show the most relevant pages pertaining to a user’s
search query. These signals include things like keyword in title tag,
content length, keyword density, freshness and uniqueness of content and
so on. One such specific signal of the algorithms is called Penguin ,
which was first launched in 2012.
After almost couple of years of development and testing, Google, on 23rd
Sep 2016 finally confirmed that its Penguin algorithm update (4.0) is
finally rolling out in all languages.
Here’s what has changed:
1. Penguin is now real time: The last Penguin update was rolled out
nearly 2 years ago on October 17, 2014. Any site that was hit by Penguin
algorithm would have waited till today to be free from the penalty. With
the latest Penguin release, Google announced that these delays are now
to be a thing of past, as Penguin becomes real time. Penguin’s data is
refreshed in real time, so changes will be visible much faster,
typically taking effect shortly after Google’s algorithm recrawl and
reindex a page.
2. Penguin is now more granular: Penguin initially was a site wide
penalty. This time the update will affect finer granularities than
sites. This means that specific sections or specific pages on the site
will be affected rather than entire site.
3. Google will no longer confirm Penguin update: Since, Penguin is
now real time, Google will no longer confirm future Penguin updates.
