How does the DoubleClick Dart Cookie Work?
The special DoubleClick Dart Cookie gathers data that is used to enable AdSense publishers to serve ads on their blogs and websites and to improve advertising. This is done by directing advertising to the user based on what is pertinent to them based on what they have previously searched for or viewed.
Publishers must notify users
With most state and federal laws governing websites and blogs, it is about disclosures. Specifically, disclosing what types of mechanisms you use to gather information from your visitors and users, the types of information you gather, how you will use it, and who you will share it with.
