Which information should be on the first layer of my cookie banner?
Certain information should be immediately visible in your cookie banner. It must be clear as to who processes the personal data and for what purpose or purposes. This is the information that you put on the ‘first layer’ of your cookie banner. In this way, your website visitor knows what the consent is intended for.
Other information may be placed on a second (or lower) layer. Of course, this does not change the fact that you must offer all information in a distinct manner.
