What is a cookie consent banner?

Cookie consent banners are notices that appear on websites to inform users about how many cookies they use and why they use them, as well as to collect user consent. Cookies are small data files stored in a user’s web browser when the user visits a website.

Privacy legislation like GDPR requires websites to inform users about how and why they collect personal data and to get their explicit consent before collecting the data. For cookies, cookie consent banners are the most common method of collecting consent. Cookie consent banners must be clear, concise, effective, and compliant with relevant laws. It must be presented in a way that users can accept or reject cookies easily and conveniently.
