What is Core Algo Update?

Google’s core algorithm consists of traditional ranking factors as well algorithms designed to catch and remove spam.

A core update is different. The way I understand it, a core update is a tweak or change to the main search algorithm itself. You know, the one that has between 200 and 500 ranking factors and signals (depending on which SEO blog you're reading today).

A core update is a significant change Google makes to its ranking algorithm that affects a large number of indexed web pages. They occur about once every two or three months on average.
