How Often Does Google Update Its Algorithm?
Google changes search constantly. Here is how often it updates its algorithm, what core and broad core updates are, how they differ from targeted updates, how Google announces them, how long they take, and what Search Liaison is.
Google makes thousands of small changes a year, most unannounced, plus a handful of larger named updates. Core updates are significant, broad reassessments of how content ranks; a broad core update is Google's term for these. A targeted update addresses a specific issue like spam. Google announces major updates through Search Central and Search Liaison, and rollouts often take days to weeks. Search Liaison is Google's official channel for search communication.
How often Google updates, and what core updates are
Google makes thousands of small changes to its search systems every year, most of them unannounced, alongside a handful of larger named updates. Change is constant; because most updates are minor and go unnoticed, the important ones to watch are the bigger announced updates that can noticeably affect rankings. Google core updates are significant, broad changes to how search ranks content, and a broad core update is the term Google uses for these wide-ranging releases. They affect many sites at once; because they reassess overall quality rather than target one issue, core updates can shift rankings widely and are not about a single fixable fault, which is why we cover the history of them in our major updates history.

Core vs targeted, announcements, rollout times, and Search Liaison
A core update is a broad, general reassessment, while a targeted update addresses a specific issue like spam or product reviews. The scope is the difference; because a targeted update focuses on one area, its effects are narrower, whereas core updates can influence rankings across the board. Google announces major updates through its Search Central channels and Search Liaison, and rollouts often take from a few days to a few weeks to complete. Patience is needed during a rollout; because rankings can fluctuate until an update finishes, it is best to wait for a rollout to complete before judging its full impact. Google Search Liaison is an official channel Google uses to communicate with the public about search, including confirming updates and offering guidance. It is a reliable source; because it speaks for Google on search, following Search Liaison is one of the best ways to get accurate update information rather than speculation, which helps when you need to diagnose a traffic drop.
