 To gather anonymous summary demographic information about our visitors such as gender, age range, and areas of interest for adults over the age of 18. We do this by using Google Demographic and Interests reports. When you visit a website that has partnered with the Google Display Network, Google stores a number in your browser using a persistent cookie to remember your visits. This number uniquely identifies a web browser, not a specific person. Browsers may be associated with a demographic category, such as gender or age range, based on the sites that were visited. This demographic information is used to help us better understand our visitors' interests and needs to more effectively develop content to serve you.
