We see a lot of websites including Google Analytics or Facebook Tracking or similar JavaScript URLs before displaying Cookie Banner. Users must give consent on advertising or analytics tracking before calling external scripts i.e. from Google or Facebook.
Displaying a cookie banner with only one button like “Accept” or “Got it” is not legal. It does not give your users a free choice to reject unnecessary cookies.
Make sure that not-essential cookie groups are not pre-checked by default in the advanced cookie settings window. Explicit consent requires a very clear and specific statement of consent.
YES, you can. You will have to get rid of all non-essential 3rd party JavaScript URLs from your website. Follow the GitHub cookie story for more info.
