Your website or service needs to provide clear and comprehensive information to users prior to the setting of any cookies or tracking. In practice, most organisations choose to implement a banner, interstitial (an interactive page that usually loads between one page a visitor stops on and the next or within a page as a user scrolls) or pop-up that enables the provision of information to users and also the management of their cookie consent preferences.

If your website only uses cookies that do not require the consent of users, it may not need any banner or consent management tool. However, as a matter of good practice you should still disclose on your website via a cookie policy or privacy notice which cookies you use that are strictly necessary.
