The Complete Google Algorithm Update Resource
August 8, 2014 Blog Marketing

As we all know, Google has been improving its search results since it began back in 1997. Their goal is to make sure that they return the most relevant search results possible, in the fastest way possible. It’s said that Google makes 400 updates a year. That number amounts to a minimum of one update per day.

While some of the updates released were subtle or quite unnoticeable, others hit hard and changed how a whole nation saw their SERPs.

What are they? Well, let’s go through all of major algorithm updates to see what patterns form throughout the years.
