What are cookies and why do websites use them?

To ensure the most efficient use and presentation of a website, so-called cookies are used when the website is visited. Cookies are small data packages that are sent to the user’s browser and saved there during visits of the website. When the website is visited again, this information can be sent back to the web server.

Cookies are used to save personal page settings because websites themselves cannot store data. They are also used to identify users and to analyse their usage behaviour. Cookies serve many different purposes and are therefore differentiated according to their function, life span and source. There are for example temporary and permanent cookies. Temporary cookies are deleted either after a certain time defined in the cookie or at the end of a browser session. Permanent cookies are permanently stored in the browser.

Third-party cookies:

In this process, advertising partners do not collect any personal information such as names, e-mail addresses, post addresses or phone numbers.

The following types of cookies are used on websites

Technical cookies:

In order to show a modern and user-friendly website, technical cookies are indispensable. Without these cookies, data which is entered during the visit of a website cannot be cached and processed (typical examples are products in a shopping basket or prior selections of products/services when the user goes back during a session).

Functional cookies:

Functional cookies can be used to improve the usability of a website. These cookies are not essential for the function of a website but improve the usability during the visit of the website. They are used to save settings like the preferred language or interests so that they do not have to be entered again during future visits.

Analytical cookies:

Analytical cookies are used to get information on the users’ usage of the website, which topics led them on the website or which topics or articles are particularly interesting and relevant to steadily improve the services provided. Not only visited pages, referring pages and exit pages, but also information on the length of stay and clicks can be stored.

Commercial cookies:

Moreover, cookies can be used during marketing campaigns to show advertisements on other websites. For this purpose cookies and retargeting tags are used for interest-based advertising by online advertising providers on one’s own website.

Cookies by social networks:

In order to like and share elements such as pages, pictures and videos in social networks such as Facebook, Twitter, Google+, YouTube, Pinterest, Instagram etc., social plug-ins are integrated on a website.
