Ten Common Compliance Mistakes in KVKK Complaints About Websites

KVKK is not just a legal obligation for all companies that process data in a digital environment;
It is a critical building block in terms of brand reputation, user trust and digital sustainability.
As of 2025, the number of individual applications and complaints to the KVKK has increased rapidly,
Data processing activities, especially through websites, have become one of the most studied areas.

Board decisions, audits and official reports show most website-related KVKK violations stem from
basic compliance errors, mainly process gaps rather than technical issues.

B10 Digital’s Privacy Intelligence Framework integrates website KVKK compliance
across technical, legal and operational processes, creating audit-ready structures.

Why does the bulk of KVKK Complaints Come from Websites?

Websites combine cookies, forms, contact areas, membership systems and measurement tools, hosting
many personal data processing activities at once.
Therefore, it is one of the areas where mistakes are made the most.

• Busy data processing traffic
• Third-party tools operating unseen
• Failure to properly configure cookie management
• Lack of transparency
• Technically misconfigured consent mechanisms

The 10 Most Common KVKK Compliance Errors on Websites

The following errors stand out among the main reasons for website-related complaints in Board decisions.

1) Lack of privacy notice or being in the wrong place on the website

Many sites omit the privacy notice or bury it in the footer where it is not visible.

2) Unauthorized operation of cookies

Automatic loading of analytics, advertising and marketing cookies without user consent is one of the most critical violations.

3) Misconfigured Consent Management Platform (CMP)

• Not designing buttons equally
• Hiding cookies other than mandatory cookies
• Failure to provide a Denial option
• Sharing data without approval

4) Uncontrolled use of Google Tag Manager

Many companies run dozens of third-party tools through GTM without tracking their data flows.

5) Incorrect balance between explicit consent and legitimate interest

Requiring consent for every activity and obtaining no consent at all are the two typical extremes.

6) Missing information on contact form, membership form and offer form

Missing privacy information, unnecessary data collection and unstated legal bases in forms are frequent grounds for complaints.

7) Data controller contact information is incomplete or incorrect

Omitting contact details for complaints and requests directly causes a violation.

8) No website process for KVKK requests

Without clear KVKK request methods and contact channels, users complain to the Board.

9) Data processing without SSL certificate

Filling out forms on non-HTTPS sites is a serious data security violation and is frequently involved in complaints.

10) Cookie policy not in accordance with current legislation

Many cookie policies have been copied from the GDPR or prepared according to older legislation.
The KVKK framework has different requirements.

70 percent of KVKK complaints coming to websites are due to cookie management.
The key is to prevent cookies running before consent and to inform users correctly. The Board's Method of Evaluating Complaints in 2025

As of 2025, the Board specifically examines the following areas in website complaints:

• Permission mechanism of cookie and tracking technologies
• The content and accessibility of the privacy notice
• Third-party data processing activities
• Proper handling of requests
• Transparency and data minimization principle

If not all necessary elements are present, the data controller faces the risk of administrative sanctions.

B10 Digital Web Compliance Model: Three Layers

In website compliance, B10 Digital's model consists of three main headings:

1. Technical measurement and cookie inventory
2. Legal documents: privacy notice, KVKK policy and cookie policy
3. Operational compliance: internal processes, request handling and logs

This approach makes websites secure in terms of both data protection and digital reputation.

Conclusion

Websites are one of the most risky areas where KVKK complaints are concentrated.
Without appropriate cookie management, transparent information, sound technology and legal compliance together,
Brands face both administrative fines and the risk of loss of reputation.

B10 Digital’s Privacy Intelligence Framework combines
technical scanning, legal compliance, data mapping, log analysis and continuous monitoring
to make websites audit-ready, sustainable and KVKK-compliant.
