When Google Penguin launched back in 2012, it used over 200 unique signals to blacklist websites it considered to contain spam. Webmasters hit with these spam notifications had to work hard to redeem their websites in order to be re-added to the overall index.
Last week, the Penguin algorithm was updated and now the data is refreshed in real time, so changes will be visible much faster, typically taking effect shortly after Google re-crawls and re-indexes a page. This means no more periodic culls of websites, sending waves throughout the internet.
The new Penguin update is also much more granular. The algorithm now devalues spam by adjusting rankings based on the array of signals, instead of effecting the ranking of the whole site. This update also integrates Penguin into the core Google algorithm, whereas it used to be a standalone system, so Google will no longer provide Penguin-specific updates.
For those in digital marketing, it helps support the notion that it is quality over quantity. Content marketing needs to focus on producing high quality information, instead of simply amassing backlinks. The new penguin update is also in all language as well, so international content cannot escape the reach of the new real time Penguin.
