What is a cookie banner and do I need a cookie bar on my website?

ANSWER

A cookie banner is a pop-up window that appears when a website is visited. A cookie banner is used to ask the visitor to the website for consent to store and read cookies. This consent must be obtained from the person visiting the website if the cookies used are not technically necessary.

If a website uses only technically necessary cookies, asking for consent is not required, and therefore a cookie banner is not required either.
