What is a Cookie Consent Banner and What Does it Do?

A cookie consent banner’s primary function is to inform website visitors about the data collection practices on the site, particularly the use of cookies and scripts—those small files that can track, store, and analyze visitor behavior.

The objective is to obtain a website visitor’s consent for collecting non-essential cookies, fostering a relationship built on trust and informed choice; it should also allow a visitor the ability to revoke that consent. A valid cookie consent banner is more than a pop-up; it's a digital handshake, an invitation for transparency between a website and its visitors.


Is a Cookie Banner a Legal Requirement?

It depends on the jurisdiction, however the answer is generally yes. Across the globe, from the rigorous standards of GDPR to the consumer-centric mandates of CPRA, cookie consent banners are often legally mandated. These laws compel websites to clearly inform visitors about data practices and either secure explicit consent for non-essential cookies or allow those visitors to opt-out of collection practices so that visitors have a say in how their data is used.

What Should a Cookie Consent Banner Do?

An effective cookie consent banner should:

  1. Inform Visitors: Offer clear, concise information on what cookies the website uses, their purpose, and how they impact the visitor experience.
  2. Obtain Consent: Provide a straightforward mechanism for visitors to consent to or reject cookie usage, with options to customize their preferences depending on a given jurisdiction’s regulatory requirements.
  3. Facilitate Compliance: Requirements change depending on jurisdiction, so what works in California may not work in Croatia. A website’s cookie consent banner should be flexible to accommodate multiple jurisdictions to facilitate compliance based on where the website visitor is accessing the website.
  4. Support Universal Opt-Out: May regulations require websites to allow visitors to easily opt-out of all cookies, so websites should include a “reject all” button for those geographies.
  5. Actually Work: Many cookie consent banners don’t actually execute the choices a website visitor makes, which can put the website owner in violation of various privacy regulations. With a variety of products on the market the website owner should perform requisite due diligence to understand the functionality of a vendor’s cookie consent banner.

Which Privacy Laws Require a Cookie Consent Banner?

The legal landscape for cookie consent banners spans continents, reflecting a global push for data privacy. Some of the privacy regulations that require a cookie consent banner include:

  • GDPR (EU): Mandates explicit visitor consent for non-essential cookies, emphasizing visitor autonomy and data protection.
  • CCPA (California): Requires clear notification of data collection practices and mandates explicit visitor consent for non-essential cookies.
  • LGPD (Brazil): Requires that visitors are informed and consent to data collection, reinforcing data privacy rights in Latin America's largest economy.
  • PIPEDA (Canada): Imposes obligations on businesses to obtain meaningful consent for data collection and use, upholding transparency and visitor control.

Is a Free Cookie Consent Banner Ever Enough?

Probably not. Free cookie consent banners often fall short in customization, visitor experience, and advanced analytics. Premium solutions provide enhanced features, facilitating robust compliance and a seamless visitor experience. Think about it: developing compliance software and keeping up with the ever-evolving regulatory landscape is expensive; how could a company offer a free platform that actually works?

Cookie consent banners can come in the form of a footer, a popup, a full page banner (or cookie wall), or a header style cookie banner. Here are some examples.

FAQs on Cookie Consent Banners

Do all websites need a cookie consent banner?

Generally yes, to comply with various data privacy regulations any website using cookies, especially non-essential ones, requires a cookie consent banner. An exception to that rule is that jurisdictions that don’t have a data privacy regulation don’t require a cookie consent banner, but remember that these privacy regulations are generally concerned with where a website visitor is coming from, not where the website’s owner is based. That means organizations should take preventive measures so that they are seeking to comply with data privacy regulations wherever visitors are accessing their website.

What information should a cookie consent banner include?

It should explain what cookies are, the types used, their purposes, and provide options for visitors to accept, reject, or customize their cookie preferences.

Can I use a free cookie consent banner and still comply with privacy laws?

You can, but free banners are unlikely to help you achieve basic compliance, and they almost certainly will lack advanced features and customization. Consider your specific needs and the benefits of premium solutions.

What are the penalties for not having a cookie consent banner?

Penalties include legal fines, loss of visitor trust, decreased website traffic, and potential damage to your brand’s reputation.

How can my cookie consent banner comply with different privacy laws?

Use a banner that supports frameworks that provides a flexible UX for visitors so that you can facilitate compliance in various jurisdictions. Also, you should work with a company that stays updated with legal requirements in global jurisdictions.
