On Monday, Google announced a new set of tools to help users determine and control which ads they see while using Google search or Gmail. From their announcement:

Ever been searching Google for something and you saw an ad displayed and thought, “How the hell is that relevant?” Now with a single click you can see why Google paired that ad with you and block others from annoying sources.

While I feel this is a step in the right direction, I still recommend logging out of Google services before using their search tool and clearing your cookies religiously. This will help ensure your search results are less biased towards previous activities and searches you have performed on Google.

Their announcement also included a video giving an overview of the new tools, and how to use them. I have embedded the video below for your convenience.
