A tracking cookie is a special type of web cookie that is placed to identify an internet user on one or more websites. Based on the pages that someone visits, general knowledge can be obtained about the way in which a website is used, but it is also possible to determine, for example, what the person is interested in. Building profiles with such information can then be used for behavioral targeting, showing banner ads from related advertisers.
Because tracking cookies are usually placed from external domain names by other parties, they are also referred to as third-party cookies.
The application of tracking cookies has been subject to certain conditions since the introduction of the GDRP in the EEA. For example, visitors must be informed about the data that is collected and it must be possible to disable these cookies. Certain cookies may only be placed if the visitor has given permission for this. This applies, among other things, to marketing cookies such as tracking cookies.
