RGPD Cookies: the mistakes that make encore too many non-conformed sites expose companies to penalties, loss of trust, and often invisible technical risks.
Why RGPD cookies remain a weak point for websites
Installing a consent banner is not enough to make a site conformed. The RGPD governs the collection, processing, retention, and security of personal data, far beyond the simple display of a cookies banner.
The problem often comes from a gap between appearance and how the site actually works. A banner may seem correct on the user side while still allowing Google Analytics, ad pixels, or third-party trackers to fire as soon as the page loads.
For a small or medium-sized business like Atelier Nova, a showcase site, form contact form, and social campaigns can already involve several data processing activities. Without a technical audit, management may think it is protected while the browser still reveals encore marketing cookies being set before any explicit choice.
A solid compliance framework therefore relies on three pillars: valid consent, reliable technical implementation, and clear documentation. It is precisely on these points that a web agency and mobile agency like DualMedia comes in during a redesign, a WordPress audit, custom development, or optimization UX.
RGPD Cookies and consent: the mistake of a banner that blocks nothing
The most common non-conformity remains the banner that appears without preventing non-essential trackers from launching. As long as the user has not accepted, no advertising cookie, non-exempt analytics cookie, or social network tracker should be set.
Simply presenting an accept button does not create valid consent. The site must technically pause the relevant scripts, then activate them only after a positive action by the user.
A quick test can identify the mistake. Just open the browser developer tools, go to the Application or Storage tab, then reload the page without clicking the banner. If third-party cookies already appear, consent is not correctly respected.
This check is particularly important during a CMS migration, a redesign, or the addition of marketing tools. The DualMedia teams review this point from the start of integration to avoid treating conformity as merely a graphic layer.
The dark patterns that invalidate cookie consent
RGPD consent must be freely given, informed, specific, and unambiguous. If the accept button is very visible while the reject button is hidden, grayed out, or only accessible after several steps, the user's choice is biased.
Pre-checked boxes for marketing cookies are also bad practice. The user must express a clear intent, not corrridge an option already selected for them.
The operational rule is simple: if one click is enough to accept, one click must be enough to reject. This symmetry reduces the risk of penalties and also imporves brand perception, because the user understands that they truly remain in control.
In a mobile journey, the challenge is even more sensitive. A banner that is too intrusive, hard to read, or difficult to close harms the user experienceuser experience as well as compliance.
Forms, personal data, and processing records
RGPD cookies are only part of the issue. A form contact form often collects a name, email address, phone number, free-form message, and sometimes even sensitive professional information.
Each collection point must clearly inform the user. You need to specify the purpose of the processing, the legal basis, the retention period, any recipients, and the available rights, such as access, correction, or deletion.
A link to a privacy policy may be enough if the document is complete, readable, and up to date. To go further, companies can consult dedicated resources on the privacy policies in order to better structure their notices and obligations.
The processing register is also far too often missing. Yet, in the event of an inspection, it is one of the first items requested to understand what data is being processed, why, for how long, and by which providers.
- Identify all the forms on the site, including newsletter, quotes, recruiting, and customer account areas.
- Make sure each collection links to clear, up-to-date information.
- Document the third-party tools used for analytics, advertising, CRM, or support.
- Link each processing activity to a purpose, a legal basis, and a retention period.
- Provide a simple procedure for responding to access or deletion requests.
Compliance becomes more robust when it is documented as a business process, not as a fixed legal page.
Retention periods: the oversight that weakens GDPR compliance
Keeping personal data indefinitely goes against the principle of storage limitation. Yet many sites still retain prospect emails, job applications, or old customer accounts without any clear deletion rule.
Retention periods must be consistent with the purpose. For example, inactive prospect data should not remain in a CRM for years without justification, and resumes from candidates who were not selected must be purged or archived according to a defined rule.
In practice, the difficulty often comes from interconnected tools. A form feeds a CRM, an email solution, a shared spreadsheet, and sometimes an automation tool. Deleting data in only one place is therefore not always enough.
This logic aligns with application security best practices. The same habits used for securing a mobile application also apply to websites: limit access, log processing activities, encrypt sensitive data, and delete what is no longer useful.
Comparative table of GDPR cookie mistakes to fix
An effective audit must distinguish the visible error from its technical cause. The table below summarizes the most common situations and the priority actions to implement.
| Error identified | Main risk | Recommended fix |
|---|---|---|
| Analytics scripts launched before consent | Illegal placement of non-essential trackers | Blocking tags until explicit acceptance click |
| Reject button less visible than accept | Consent considered biased | Offer accept and reject at the same level of simplicity |
| Marketing checkboxes pre-checked | Invalid consent | Leave all purposes disabled by default |
| Form without GDPR information | Insufficiently transparent data collection | Add a clear notice or a link to a complete policy |
| No record of processing activities | Difficulty proving compliance | Document the data, purposes, legal bases, and retention periods |
| Data kept indefinitely | Violation of the minimization principle | Define automated archiving and purge rules |
This type of analysis makes it possible to move from a legal finding to a concrete action plan. Compliance becomes something that can actually be managed by web, marketing, security, and leadership teams.
How to audit a website without limiting yourself to the banner
A serious GDPR audit starts with the browser, but it does not stop there. You need to analyze cookies, scripts, forms, connected tools, server logs, internal policies, and third-party providers that receive data.
The first step is to map the trackers. Analytics, ad networks, interactive maps, embedded videos, chat tools, AB testing solutions, and WordPress plugins can all place elements on the user’s device.
Next, the team checks the consent flow. Can the user refuse as easily as accept? Can they change their choice? Does the site retain proof of consent without creating a new excessive collection?
Finally, the audit must include the technical architecture. Lorsqu’une company is preparing a redesign or seeking to choose a web development company, it is worth integrating these requirements into the specifications from the outset.
- Test the site without accepting cookies and note the trackers already present.
- Check the symmetry between accept, refuse, and configure.
- Verify the notices associated with formulaires and user accounts.
- Review the third-party tools connected to the site and any potential data transfers.
- Update the processing register and retention periods.
- Plan regular checks after each addition of a plugin, tag, or feature.
An audit is only valuable if it leads to measurable corrections. It is this shift from recommendation to implementation that often makes the difference between a reassuring site and a truly conforming one.
GDPR Cookies, web performance, and user experience
Compliant behavior is not at odds with performance. On the contrary, blocking unnecessary scripts before consent sometimes reduces the initial page weight, improves load times, and limits unnecessary external calls.
A well-designed banner can also strengthen the user experience. It informs without abruptly interrupting browsing, adapts to mobile screens, and makes it possible to understand the purposes without excessive legal jargon.
This approach aligns with product design challenges. In a web or mobile project, privacy-related choices must be considered alongside UX, SEO, security, and performance, not added at the end of the project.
DualMedia favors this logic from the design stage: limit the data collected, clarify user journeys, secure processing, and preserve site fluidity. Conformance then becomes a lever for trust rather than an isolated constraint.
Our opinion
GDPR cookies remain a sensitive topic because they combine law, technical matters, marketing, and user experience. Most mistakes do not stem from bad intentions, but from incomplete implementation or a stack of poorly controlled tools.
The right approach is to treat conformance as a web quality requirement. A site must load quickly, convert, be accessible, protect data, and prove its choices in the event of an audit.
For companies, the best reflex is to check how the site actually works rather than the appearance of the banner. A short audit can reveal scripts that activate too early, formulaires that are insufficiently documented, or data retained without justification.
By integrating data protection from the design stage, a site gains reliability, trust, and durability. It is often this level of rigor that distinguishes a simple online site from a true professional tool.
How to make RGPD cookies conformes on a website?
All non-essential trackers must be blocked before consent. The site must also offer a clear choice between accepting, rejecting, and configuring, with understandable information on each purpose.
Does a cookie banner alone suffice to comply with the GDPR?
No, a banner alone is not enough. It must be tied to actual technical blocking of scripts, a complete privacy policy, and documented management of data processing activities.
What cookies can be placed without consent?
Only strictly necessary cookies may be set without prior accord. These include trackers essential for the operation of the shopping cart, security, or the user session.
Why are analytics cookies a problem under the GDPR?
Analytical cookies pose a problem when they enable non-exempt tracking without consent. Some tools can be configured in a more privacy-respecting way, but their settings, purpose, and actual triggering need to be verified.
Should the reject button be as visible as the accept button?
Yes, refusing must be as simple as accepting. If accepting requires a click, refusing must also be accessible in one click, without a discouraging path or deceptive design.
How to check whether GDPR cookies are being set too early?
The site must be tested before any click on the banner. Browser developer tools make it possible to view stored cookies and identify third-party trackers already present at load time.
Are contact forms subject to the GDPR?
Yes, the fororms are directly affected. They collect personal data and must inform the user about the purpose, retention period, available rights, and any possible recipients.
How long can data collected on a website be retained?
The retention period depends on the purpose of the processing. A company must establish consistent rules, delete data that is no longer needed, and avoid any indefinite retention without justification.
What is an RGPD processing records register?
This is a document that lists personal data processing activities. It specifies, in particular, the categories of data, the purposes, the legal bases, the retention periods, and the recipients.
When should a website’s GDPR cookies be audited?
An audit is recommended when creating, redesigning, or adding a marketing tool. It is also useful after installing a plugin, an advertising tag, a chat module, or an analytics solution.
