What is cookie consent?

That banner appearing on every website is not a design fashion but a legal obligation with precise rules, and the majority of implementations break them. European privacy legislation on electronic communications, together with the GDPR, requires that any cookie not strictly necessary to the operation of the site — traffic analytics, advertising, social media pixels — is placed only after the visitor's explicit agreement. Explicit has concrete consequences: the reject button must be as visible as the accept button, nothing may be pre-ticked, continuing to browse does not count as agreement, and marketing cookies must not load before the click. For your company the stake is twofold. There are penalties under the applicable legislation for non-compliant banners, a subject increasingly visible in European enforcement practice, and there is the trust of visitors, who have become adept at recognising manipulative banner design. A properly built site treats consent as a functional requirement rather than a sticker applied at the end.
