Links that you have copied directly from online stores, Google, social platforms or other sites often contain tracking information that you should always delete before sharing.

More information

The link https://example.com/artikel?utm_source=newsletter&utm_medium=email&fbclid=XYZ123, for example, contains a large number of so-called query parameters that reveal who has shared the link and where it comes from. This allows tracking networks to recognize who is sharing information with whom. The example link shown here contains the information that it was sent to you via a newsletter. It also contains an ID 'XYZ123', which uniquely identifies you. Can you see the question mark in the link? Everything behind it is in most cases irrelevant for accessing the target page. The cleaned link is therefore simply https://example.com/artikel

Sometimes, however, the parameters are also important in order to call up certain content on the pages. You can easily test this by calling up the cleaned link yourself. You should always be skeptical when cryptic strings are included in the links. You are welcome to use the open source app 'Léon' to automatically clean the links.

Particularly important for the following target groups:

  • Advertising and marketing

Other categories

  • Behavior-based risks
  • Dangers on the Internet
  • Rather simple
