Google algorithms are a complex system used to retrieve data from its search index and instantly deliver the best possible results for a query. The search engine uses a combination of algorithms and numerous ranking factors to deliver webpages ranked by relevance on its search engine results pages (SERPs).

In its early years, Google only made a handful of updates to its algorithms. Now, Google makes thousands of changes every year.

Below, we have compiled a comprehensive list of Google algorithm updates sorted by their release dates.
