In reality, Google’s Core Algorithm is made up of millions of smaller algorithms that all work together to surface the best possible search results to users. What we mean when we say “Google’s Core Algorithm” is the set of algorithms that are applied to every single search, which are no longer considered experimental, and which are stable enough to run consistently without requiring significant changes.

Google Panda (2011-2016)

The Panda algorithm focused on removing low quality content from search by reviewing on-page content itself. This algorithm focused on thin content, content dominated by ads, poor quality content (spelling/grammar mistakes), and rewarded unique content. Google Panda was updated

29 times before finally being incorporated into the core algorithm in January of 2016.

Google Penguin (2012-2016) The Penguin algorithm focused on removing sites engaging in spammy tactics from the search results. Penguin primarily filtered sites engaging in keyword stuffing and link schemes out of the search results. Google Penguin was updated 10 times before being integrated into Google’s core algorithm in September of 2016.

RankBrain (2015-Present) This machine-learning based AI helps Google process and understand the meaning behind new search queries.

Within three months of full deployment RankBrain was already the 3rd most important signal contributing to the results selected for a search query.
