Google Updates are important events for webmasters and SEOs everywhere. These algorithm changes, filters, data refreshes or other alterations are often to blame when a website suffers a drop in ranking or SEO Visibility. This page provides an overview of all important Google Updates, going back to 2010.
Short introduction to Google Updates
A Google Update, such as the Mobile Update or Phantom Update, is the term used to describe a change affecting how rankings are calculated by the search engine, Google. Some updates are major algorithm changes and others may be the application of filters of a refresh of the data basis that an algorithm runs on. The general aim of any update is always to improve the relevance and quality of the search results, with most changes focusing on one or more particular features, such as an optimization to fight search engine spam or to combat duplicate content.
Most updates are initiated manually and rolled out for Google’s individual country indexes. Some updates, like the Penguin Update or Panda Update, are already part of Google’s so-called “core algorithm”. They have become so integral to the search engine that they now develop continuously and automatically, and are no longer manually updated.
Each year, Google implements over 600 adaptations and updates to its algorithms. Most of these alterations take place unnoticed and are not announced within the search engine industry.
The most significant Google Updates take place when there is an adjustment to the structure and functionality of the algorithm. These have more of an impact a Data Refresh, which does not add any new features to the core algorithm, and simply updates the data used by the algorithm.
