What is the new cookie rule?

The new cookie rule is that all cookies must be declared in the HTML head section of a web page. This rule applies to all cookies, whether they are first-party or third-party cookies. The purpose of this rule is to ensure that users are informed about the use of cookies on a website and to allow them to block or delete cookies if they wish.

This rule is part of the European Union's e-Privacy Directive, which came into effect on May 25, 2018. The directive requires all websites that use cookies to provide clear and concise information about the use of cookies and to obtain the user's consent before setting or accessing any cookies.

The new cookie rule is likely to have a significant impact on the way that websites use cookies, as well as the way that advertisers target users with online advertising. Many websites will need to make changes to the way they use cookies to comply with the new rule.

Some experts have suggested that the new cookie rule could lead to a decrease in the use of cookies, as well as a decrease in the effectiveness of online advertising. However, it is too early to say what the long-term impact of the new rule will be.
