While pop-up boxes and banner notifications alert users that cookies are being used and can allow for an option to opt out within that box or banner, this kind of policy is where further information can be detailed and presented to your visitors.
The EU’s GDPR requires that you get consent to use most cookies, and having a cookie notification is the perfect way to do this.
