Which website errors most commonly lead to fines?

The top 3 triggers are: (1) tracking without consent (Google Analytics, Meta Pixel, Matomo without prior approval), (2) missing or inadequate privacy policy, particularly not available in the local language, and (3) unlawful data transfer to US service providers (cloud services, CRM systems, video hosting) without Standard Contractual Clauses or Binding Corporate Rules. These three categories account for roughly 70% of all fines in the website context. The good news: all are fixable with relatively modest effort. An audit of your current tools and functioning cookie management are the minimum. After that, you can proceed systematically and prioritise.
