Cookies e trackers antes do consentimento

Porque isto importa

De acordo com a ePrivacy e os princípios do RGPD, armazenamento e tracking não essenciais exigem consentimento antes da ativação. Carregar scripts de analytics ou marketing antes da escolha do utilizador cria risco imediato de conformidade.

Como verificar manualmente

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.

Causas típicas

• 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.

Correção no 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.

Correção em WordPress ou plugins CMP

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.

Correção genérica para developers

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>

Como confirmar que a correção funciona

• 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.
