5. Advertising and Tracking Cookies

We sometimes use tracking pixels to assist with our online advertising and marketing to effectively promote the University and have a better understanding of what our audiences are interested in.  These cookies are anonymous and they help us collect information on our advertising campaigns. This, in turn, allows us to make our ads more relevant to our website users. This means you should generally only see ads relating to your personal interests and you won’t constantly see the same ones. They allow us to interact with you once you’ve left our website.
Trinity College may advertise using the Google Display Network to deliver online content such as imagery, text and videos on participating websites.  For example, if you have looked at certain pages on our website we might want to highlight upcoming events or give you more information about a specific course.  This process uses google remarketing technologies, is anonymised and you can opt out of these cookies at any time. On some occasions, Trinity College may also use DoubleClick which is required for advertising frequency capping.
