Nowadays, online tracking technologies are so integrated into our daily browsing that they often go unnoticed. Every time we visit a website, interact with ads, or simply accept a cookie banner, we are allowing the collection of information about our digital activity. This tracking ecosystem — now a cornerstone of marketing, web analytics, and content personalization — is governed by a strict legal framework, especially in EU countries like Spain.
Cookies, along with similar technologies such as tracking pixels, fingerprinting, or analytic scripts, enable the collection of data on users’ browsing habits. These data can be used for many purposes, such as measuring website performance, displaying personalized ads, or even predicting future user behavior. But beyond their technical functionality, these tools involve the direct or indirect processing of personal data, which activates all the legal safeguards provided by European regulations.
In this context, it is crucial to understand that the use of cookies is not merely a technical issue, but a legal one. Any company using these technologies on its website — whether a small eCommerce business, a tech startup, or a large digital enterprise — must comply with a series of obligations clearly defined by the General Data Protection Regulation (GDPR), the EU ePrivacy Directive, and Spanish legislation such as the Law on Information Society Services and Electronic Commerce (LSSI).
One of the core principles governing this area is prior consent. This means that cookies or tracking technologies may not be installed in a user’s browser without their explicit and informed authorization, unless the cookies are strictly necessary for the website’s operation. This requires websites to implement a transparent and accessible consent management system that allows users to freely choose which types of cookies to allow or reject.
It is often overlooked that consent must be informed, meaning a clear, complete, and understandable explanation must be provided about what data is collected, for what purpose, how long it will be retained, and whether it will be shared with third parties. This information must be available both in the initial cookie notice and in a cookie policy that is accessible at all times from the website. Additionally, users must be able to modify or withdraw their consent as easily as they gave it.
Furthermore, consent is not valid if it is obtained ambiguously or by omission. Phrases like “by continuing to browse, you accept the use of cookies” are no longer compliant with current regulations. The user must take a clear and affirmative action, such as clicking an acceptance button or selecting their preferences in a settings panel. Otherwise, any tracking technology activated without this explicit action is operating illegally.
Failing to meet these legal obligations is not a minor issue. In recent years, the Spanish Data Protection Agency (AEPD) has imposed numerous fines on companies for violating cookie regulations. These penalties affect not only large corporations but also small and medium-sized enterprises, marketing agencies, bloggers, and online stores. Fines can be significant, and beyond the financial impact, such violations can cause serious reputational damage — especially in industries where user trust is key.
In this landscape, companies with an online presence are strongly advised to take proactive measures to ensure legal compliance. This includes implementing certified Consent Management Platforms (CMPs), regularly reviewing the cookies active on their site, drafting a clear and up-to-date cookie policy, and training staff involved in web development, marketing, or analytics. It’s also essential to maintain documented records showing when and how user consent was obtained.
This is not just about avoiding penalties — it’s about building transparency and trust with users. Today more than ever, digital privacy is a differentiating factor. Users are increasingly aware of how their data is used and value companies that act responsibly and transparently. Demonstrating a real commitment to legal compliance on cookies not only improves user experience but also strengthens brand image and digital credibility.
In short, the use of cookies and tracking technologies is deeply connected to personal data protection. Regulations require that processing this data be based on the user’s free and informed consent, and website owners must implement mechanisms that comply with these principles. At Law 4 Digital, we work precisely at this intersection of technological innovation and legal certainty, helping our clients adapt their digital platforms to current legal requirements with rigor, efficiency, and strategic vision.
FAQs
Can I use Google Analytics without user consent?
No. Google Analytics uses analytics cookies that collect identifiable or pseudonymized personal data. This means you need the user’s explicit consent before activating them. It is essential to configure Google Analytics so it does not activate by default and give users a real option to reject it from the start.
What happens if I install cookies before obtaining consent?
You would be violating both the GDPR and the LSSI. Any cookie that is not strictly necessary for the technical operation of the website cannot be installed without the user’s prior affirmative action. This must be a clear, uninfluenced action — meaning implied consent or consent by inaction is not valid. Installing cookies without consent can lead to significant fines from the AEPD.
Do technical cookies also require user consent?
No. Technical or functional cookies — such as those that enable a shopping cart to work or keep a user logged in — are exempt from the prior consent requirement. However, users must still be informed about their use, which should be done in the cookie policy, even though rejecting them is not required.
