The consent must also be antecedent meaning that cookies may not be used before consent has been obtained.
Further, the consent must express a volunteer indication of a wish. This means that the user must actively give his/her consent e.g. by clicking onto a page, by crossing off a box or by clicking a button on the website. It is not sufficient that the user simply visits the website. The Working Party recommends that the access to a website is not made conditional on the user accepting the website's cookies.
If the owner of the website wants to be sure that the website complies with the consent requirement, all the above requirements should be met.
