If you find yourself Googling the exact dates of Google’s Algorithm changes regularly, then you will find the outline of the changes below useful.  I have tried to keep the Google updates information as simple and easy to understand as possible.  Google makes hundreds of changes to their algorithm every year, so deciphering the impact of these changes on a website can be complicated.  For that reason I have kept the list of updates only to the most important Google algorithm updates.

Penguin and Panda: The two updates that changed SEO

penguinPanda-update

Two of the biggest updates: Penguin and Panda have changed the search landscape beyond all conception, particularly in the last two years.  Improving a website’s search visibility in Google is now focused strongly on creating quality content, acquiring high quality links, and engaging your visitors.

Scalable SEO tactics employed by low quality, unscrupulous SEO agencies of the past, have shown all too often to have resulted in algorithmic and sometimes manual penalties.
