Cookies can be classified as one of the following categories:
- Necessary cookies
- Preference cookies
- Statistics cookies
- Marketing cookies
- Unclassified cookies. Please see: Check your unclassified cookies
The categorization depends on the cookie purpose:
Necessary: scripts that are needed to guarantee website functionality.
For example; a cookie enabling shopping basket functionality on an e-commerce website which is necessary for the service requested by the user (= being able to add products to the basket and buy them).
Preferences: setting user choices to navigate the website.
For example; scripts that remember whether a user has seen a popup with a discount code. These are not strictly needed for the website to work, but can make the flow easier for a user.
Statistics: used for analytical purposes
For example; Google Analytics cookies.
Marketing: used for targeting the user with (personalized) adds
For example; the Facebook pixel can be used to show specific ads to certain users.
