Cookies can be divided into two categories: first party cookies, which are
created by the domain the user has requested and third party cookies, which are
placed in the user's browser by other domains that are generally not under the
control of the first party. Whereas first party cookies are commonly not used
for tracking but for the aforementioned shopping cart functionality for example
or enabling e-commerce applications to function properly, third party cookies are
popular with data brokerage firms (e.g., Datalogix, Experian, Equifax), online
advertisers (e.g., DoubleClick) and---belonging to both of these categories in
some cases---social media platforms (e.g., Facebook). The distinction between
these two categories is not always clear, however. Google Analytics for example
is considered to be a third party but offers their analytics services by setting
a first party cookie in the user's browser in addition to loading JavaScript
snippets from their servers. Therefore, categorizing cookies into those that
serve third party web content and those that serve first party web content
presents a more adequate approach.

sharing data between multiple trackers is difficult, since there are no easy
ways to accurately match an accumulated profile history of one identifier to
another. This problem has been solved by modern trackers by using a mechanism
called Cookie Synchronization or Cookie Matching. This technique allows multiple
