Keys to a GDPR Compliant Cookie Policy
Legal Basis: GDPR vs. ePrivacy (Cookie Law Directive)
The use of cookies on websites within the European Union is regulated by two main legal frameworks: the General Data Protection Regulation (GDPR) and the ePrivacy Directive. While the GDPR sets general rules for processing personal data, the ePrivacy Directive introduces specific requirements for the use of cookies and tracking technologies.
The ePrivacy Directive, also known as the “Cookie Law,” states in its Article 5.3 that prior and informed consent is required before storing or accessing cookies on a user’s device, except in cases where they are strictly necessary for the functioning of the requested service.
The ePrivacy Regulation, which is currently under negotiation to replace the Directive, could impose even stricter requirements on cookie management, increasing transparency and reinforcing user control over their data. Its future implementation will bring significant changes to how businesses collect and process information through cookies.
Valid Consent Under GDPR: Key Requirements
Consent for the use of cookies must comply with the GDPR principles to be legally valid. Simply displaying a notice informing users about cookies is not enough; the user must give their consent freely, specifically, informedly, and unambiguously.
For consent to be valid, it must meet the following criteria:
- Clear affirmative action: The user must explicitly accept the use of cookies. Pre-ticked checkboxes, scrolling, or messages stating that continued browsing implies consent are not valid.
- Granularity: The user must be able to choose which types of cookies they accept and which they reject. An option should be available to allow only essential cookies and reject others.
- Easy withdrawal of consent: The user must be able to change their preferences at any time as easily as they gave consent. A permanently visible cookie settings button is a good practice.
- Consent record: Businesses are required to store information on when and how the user provided consent, allowing them to demonstrate compliance with regulations.
Strictly Necessary Cookies: Consent Exceptions
Not all cookies require consent. Some exceptions, known as strictly necessary cookies, can be stored without prior user authorization because they fulfill an essential function on the website.
Cookies that do not require consent include:
- Session cookies that keep the shopping cart active in an online store.
- Authentication cookies that validate user login on platforms with registered accounts.
- Security cookies that detect unauthorized access or fraud attempts.
- Interface personalization cookies, such as language selection or accessibility settings.
However, analytical cookies have been subject to varying interpretations. In some cases, anonymized first-party analytics cookies may be exempt from consent, but the latest guidance from the European Data Protection Board (EDPB) has indicated that if they can indirectly identify the user, explicit consent is required.

Mandatory Elements in the Cookie Policy
A cookie policy must be clear, transparent, and easy to understand. A generic text is not sufficient; users must be able to understand in detail what cookies are used and for what purposes.
Essential elements of a cookie policy include:
- A table with detailed information about each cookie used on the website, including its name, purpose, whether it is first-party or third-party, its duration, and how to disable it.
- Explanations about technologies similar to cookies, such as tracking pixels, localStorage, and fingerprinting techniques.
- Links to third-party privacy policies if external services like Google Analytics, Meta Pixel, or programmatic advertising tools are used.
- Information on updates and changes to the policy, including how users will be notified when modifications occur.
Cookie Banner Design: Errors That Invalidate Consent
The cookie banner is the first point of interaction between the user and the website’s cookie policy. However, many businesses have been fined for implementing banners that manipulate the user’s decision-making process.
Common errors that invalidate consent include:
- Use of “cookie walls”: Blocking access to website content until the user accepts all cookies.
- Misleading visual hierarchy: Highlighting the “Accept” button while making the “Reject” option hard to find or less visually prominent.
- Lack of granular options: Forcing users to accept or reject all cookies without allowing category-based selection.
- Ambiguous or misleading messages: Phrases like “By continuing to browse, you accept the use of cookies” do not meet GDPR consent requirements.
Data protection authorities have fined several companies for these mistakes, including a €6M fine in France for a company that made rejecting cookies difficult.
Practical Tools for Implementation
To facilitate cookie management and GDPR compliance, various tools are available in the market:
- Open-source plugins like Osano or Klaro! that offer free solutions for consent management.
- Premium platforms like Cookiebot or OneTrust that allow advanced customization and consent logging.
- Cookie policy generators like Termly or Iubenda that help draft documents in compliance with regulations.
- Preventive blocking scripts that prevent cookies from loading before consent is obtained, a recommended practice for GDPR compliance.
Real Cases Fines
Failure to comply with cookie regulations has led to significant fines in recent years. Some notable cases include:
- A Spanish company was fined for using Google Analytics without validating data transfers to the U.S., violating the Schrems II ruling.
- A company in France received a €6M fine for designing a cookie banner that made rejecting cookies difficult.
- The Spanish Data Protection Agency (AEPD) issued a warning about the use of cookies in real-time chat services, such as Zendesk, which collect data without explicit consent.
Compliance Checklist
To ensure compliance with GDPR and the ePrivacy Directive, businesses should follow these steps:
- Conduct a cookie audit using tools like CookieMetrix or Sitechecker.
- Implement a banner with a visible reject option on the first layer.
- Ensure the cookie policy is accessible from any page on the site.
- Block non-essential cookies until the user gives explicit consent.
- Maintain a record of user consent for audits.
- Review and update the cookie policy at least quarterly.
Future Trends and Challenges
Cookies are evolving, and businesses must prepare for new challenges:
- Zero-party data cookies: Collecting data with direct user consent.
- Alternatives to third-party cookies, such as Google Privacy Sandbox.
- Increase in litigation over improper tracking and lack of valid consent.
Regulatory compliance in cookie management is an ongoing process. Regularly reviewing policies and tools is crucial to avoiding fines and maintaining user trust.
