Cookies non classifiés

Pourquoi c'est important

Une finalité de cookie inconnue affaiblit la transparence et peut masquer des traitements non essentiels. La classification est nécessaire pour une information correcte et une gestion licite du consentement.

Comment vérifier manuellement

1. List all cookies set during a fresh session and after each consent action.
2. Map each cookie to the script, tag, or plugin that sets it.
3. Flag cookies with no documented owner, purpose, or category.

Causes typiques

• Legacy tags still set cookies but are no longer documented.
• CMP classification database does not recognize custom or niche cookies.
• Multiple plugins or vendors write overlapping cookies without governance.

Correction dans GTM

1. Audit tag inventory and map each tag to explicit cookie outputs.
2. Assign purpose categories and align with consent checks.
3. Remove legacy tags that set cookies without clear business justification.

Correction dans WordPress ou les plugins CMP

1. Run a full cookie scan in your CMP plugin and review uncategorized entries.
2. Map each cookie to essential, analytics, marketing, or functional categories.
3. Publish an updated cookie declaration and re-scan after deployment.

Correction générique côté développeur

1. Build a cookie register including name, provider, purpose, duration, and legal basis.
2. Default unknown non-essential cookies to blocked until reviewed.
3. Keep declarations versioned and synced with release changes.

Comment confirmer que la correction fonctionne

• Re-run cookie inventory after categorizing the unknown entries.
• Confirm declarations and CMP category labels match the runtime cookies.
• Run a fresh scan and confirm the number of unclassified cookies drops.
