Periodically Youtube, the largest video search engine, updates its internal algorithm to ensure its viewers an optimal user experience. This operation takes place in the same way and on the same days in which the other major search engine, Google, updates its algorithm in relation to the websites it indexes.

It is not for nothing that Youtube has been owned and managed by Google since 2006. The explanation of how the Youtube algorithm works is quite complex anyway this article aims to become a comprehensive guide on the mechanisms behind it. Furthermore, at the end you will find a calendar with the main Youtube algorithm update.

In the field of computer science, an algorithm is a calculation procedure to solve a more or less complex problem. Riley & Hunt (2014) define it specifically as “any well-defined sequence of actions that take a set of values as input and procedures some set of values as output”.

If we were to draw it, it would look like a flowchart, one of those diagrams with a series of blocks, each representing a different operation to be performed, and with nice arrows indicating the direction to follow.
