Another fact of the day:
If a website explicitly targets a German or Austrian audience, or is operated by a resident of one of these countries, the owner is legally required to include an Impressum page. This page serves as a form of self-disclosure.
Additionally, many Swiss websites voluntary include an Impressum for transparency, as German is one of Switzerland‘s official languages and a significant portion of its population speaks it.
Or did you think seeing so many Impressums over there in Germany is a matter of conspiracy or national habits?..
