Cookies a trackery před souhlasem

Proč je to důležité

Podle ePrivacy a principů GDPR vyžaduje neesenciální ukládání a tracking souhlas před aktivací. Načtení analytických nebo marketingových skriptů před volbou uživatele vytváří okamžité compliance riziko.

Jak to ověřit ručně

1. Open the site in a fresh private browsing window and do not interact with the banner.
2. Check the Network panel for analytics, ads, heatmap, chat, or social pixel requests before consent.
3. Inspect Application > Cookies and confirm whether non-essential cookies appear pre-consent.

Typické příčiny

• GTM tags fire on page view without consent conditions.
• CMP loads after analytics tags instead of before them.
• Scripts are embedded directly in templates and bypass CMP blocking.

Oprava v GTM

1. Enable Google Consent Mode v2 with default denied states for ad_storage, analytics_storage, ad_user_data, and ad_personalization.
2. Update tag firing rules so analytics and marketing tags only fire when consent state is granted.
3. Use consent initialization events before any marketing or analytics trigger paths.

Oprava ve WordPressu nebo CMP pluginech

1. Install and configure CookieYes or Complianz with blocking enabled for analytics and marketing categories.
2. Map services to categories and verify scripts are blocked pre-consent.
3. Clear cache or CDN and retest in an incognito browser session.

Obecná vývojářská oprava

1. Block third-party script execution until consent is granted.
2. Store pending scripts with a consent category marker.
3. On consent grant, activate only scripts matching accepted categories.

<script
  type="text/plain"
  data-consent="analytics"
  data-src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX">
</script>

Jak potvrdit, že oprava funguje

• Re-run the scan in a fresh session and confirm the finding disappears.
• Verify that no non-essential cookies are set before interaction.
• Verify that analytics and marketing requests only begin after opt-in.
