GDPR Website Check: 10 Common Mistakes

A GDPR website check quickly reveals the most common gaps that creep into a website unnoticed over time. Many of these mistakes are avoidable — often a careful look at the cookie banner, embedded services, and forms is enough to catch them. Ignoring them risks not just formal complaints, but above all the trust of your visitors. These ten mistakes come up most often in practice — and can be fixed with a bit of care.

Why a GDPR Website Check Makes Sense

Privacy isn't an end in itself — it protects you and your users alike. A website that handles personal data cleanly signals professionalism and diligence — two qualities that matter especially during a first contact with potential customers. People increasingly pay attention to such details before submitting an inquiry or making a purchase: Does the cookie banner work properly? Is there an understandable privacy policy? Are forms transmitted securely? All of this contributes to a coherent overall impression. A regular check is also considerably more relaxed than a correction made under time pressure later on — for instance when a complaint comes in or a new feature goes live unchecked. Precisely because websites keep evolving — new plugins, new forms, new marketing tools — it's worth repeating this outside look regularly, not just once at launch.

The Typical Mistakes

In practice, certain problems repeat themselves again and again, regardless of industry or company size. These include, among others:

• Incorrect cookie banner: all categories are pre-selected, or a "reject" button is missing or visually hidden.
• Tracking without consent: analytics or marketing scripts already load before a decision has been made.
• Externally loaded fonts: Google Fonts or similar services are loaded directly from the provider's server, transmitting data in the process.
• Embedded maps: map services load third-party content, often without prior consent.
• Missing or outdated privacy policy: new tools or services were added, but the policy was never updated.
• Insecure forms: contact or application forms transmit data unencrypted or store it without a clear purpose.
• Missing or incomplete legal notice: easily overlooked, especially on smaller websites.
• Social media plugins without protective measures: like buttons and embeds that transmit data in the background.
• Missing data processing agreements: with hosting, analytics, or newsletter providers.
• No clear way to withdraw consent: users cannot easily revoke consent once it has been given.

Several of these issues often appear together because they grew historically: a tool was integrated years ago, a template was reused, a form was never touched again. That's exactly why a systematic outside look is worthwhile — one that goes through the website step by step instead of just treating individual symptoms.

Setting Up Tracking Correctly

Tracking is one of the most sensitive areas, because a particularly large amount of personal data can be collected here. The basic rule is simple: scripts that aren't strictly technically necessary may only load after active consent — not before, and not "just for testing." With a properly configured Consent Mode, this can be implemented cleanly on a technical level without losing important analytics entirely. It's also important that consent, once given, can be withdrawn just as easily as it was granted — for example via a permanently accessible cookie icon in the footer. That way, control clearly stays with your visitors, while you still get reliable data for your decisions. You can find more on this under Tracking and Data Privacy & IT Security, where we show how analytics and legal compliance can be combined.

Conclusion

A regular check keeps the website clean and protects against unpleasant surprises. It's best to build this check into your routine — for instance whenever a new tool is integrated, a form is reworked, or the website is relaunched. That way, privacy doesn't stay a one-off project but becomes part of ongoing operations, maintained just as naturally as content or design. This article does not replace legal advice.
