At the start Google was not exactly perfect at helping you find what you were looking for and it’s system was somewhat rudimentary and simply looked for exact phrase matches and sites with links, something that was once very easy to manipulate. Then Google began in 2003 to release algorithm updates to patch and fix weaknesses that could be exploited by those pesky kids! Moz and Hubspot teamed up to produce a great infographic showing the timeline of Google updates. As the saying goes, “You must know where you came from yesterday, know where you are today, to know where you’re going tomorrow.” So studying the changes in the past will undoubtedly help you look for patterns and potential changes in the future. This infographic is a must have for anyone interested in search engine optimisation.
