What is the DoubleClick cookie doing on my computer?
If you have a DoubleClick cookie in your Cookies folder, it is most likely a DART cookie. The DoubleClick DART cookie helps marketers learn how well their Internet advertising campaigns or paid search listings perform. Many marketers and Internet websites use DoubleClick’s DART technology to deliver and serve their advertisements or manage their paid search listings. DoubleClick’s DART products set or recognize a unique, persistent cookie when an ad is displayed or a paid listing is selected. The information that the DART cookie helps to give marketers includes the number of unique users their advertisements were displayed to, how many users clicked on their Internet ads or paid listings, and which ads or paid listings they clicked on.
