A broad type of Google search algorithm update that comprehensively reassesses content quality across all topics. Its impact is generally wider than that of a spam update, and it aims to improve the overall quality of search results.

Spam updates are fundamentally different from core updates: spam updates focus on enforcing spam content policies rather than comprehensively reassessing content quality across all topics.
Core updates target overall content quality assessment and recalibrate the overall logic of search rankings, with their impact usually covering all topics and query types.
Recovery after a core update typically takes 3 to 6 months.
A core update is a relatively large adjustment Google makes to its overall search ranking systems, usually several times a year, which broadly affects the visibility of a large number of websites.
