The cookie wall is an overlay which is visible immediately when loading a website and requires you to make a choice around the cookies before you can continue to browse the website. Although this seems like an 'invasive' way to obtain the necessary permissions, it is certainly not a bad one. It ensures that users know immediately that you are working with cookies and it immediately points them in the right direction for more information.
However, it is less user-friendly because it prevents the user from seeing the content he or she wants to see. It is usually used when a website depends on advertising revenue and proper permissions are required. Some websites even go so far as to prevent further use of the website if you only use functional cookies. Our advice? Test well and above all think "user experience first".
Cookie bar with clear call-to-action
The cookie bar or cookie banner is a more subtle way to request permissions for cookies. It can often be found at the bottom or top of the page, large enough to be visible, but it certainly doesn't get in the user's way like a cookie wall. The text and buttons should be clear and unambiguous. Just like the buttons you offer: one to accept and one to reject or set preferences.
With this method of working, it may happen that the user does not make any choice at all, so you can only place functional cookies. As a result, it is possible that you may lose analytical and marketing data. Our advice? It is the most commonly used format and users meanwhile know what to do.
Pop-ups and small windows
This third version is an alternative to the cookie bar. Suppose the cookie banner and the cookie wall don't fit in the design, you can also choose a pop-up or a small window in the corner of the screen. Similar to the cookie banner it is not disturbing, but it is clearly visible next to or over part of the content.
We also advise the same as with the cookie banner: make sure you have unambiguous texts and buttons and make sure you let users choose their own preferences.
