Google Algorithm Update History: An Overview Of All Google Updates

SEO Strategies


The goal of every Google algorithm change, also called Google Update, is to (further) increase the quality of the search results for the user. Google uses more than 200 ranking factors to determine the quality and relevance of each URL. Google’s ranking algorithms help to get the most relevant information from the Google index.

Things worth knowing about every algorithm change from Google:

  • How often does Google make algorithm changes?
  • What is the difference between an update and a data refresh?
  • How do I recognize an algorithmic penalty?
