What is the __Secure-3PSIDCC cookie?it needs consent first

GDPR requirements

Marketing cookies are used to track visitors across websites to display relevant advertisements. Consent is required under GDPR.

For __Secure-3PSIDCC to be compliant, it must be:

• Not set on the first visit — not even for a fraction of a second
• A consent banner is shown, and the visitor actively accepts marketing cookies
• Stays blocked if the visitor rejects or ignores the banner
• Listed in your cookie policy with its name, purpose and retention period
• Removed or invalidated when the visitor withdraws consent

How to handle it

1. 1
   Block it by default

   Configure your consent platform (CMP) or tag manager so Google doesn't load until the visitor accepts marketing cookies.

2. 2
   Map it to a consent category

   Put it under “Marketing / Advertising” in your CMP configuration.

3. 3
   List it in your cookie policy

   Name, purpose, provider (Google LLC) and expiry (1 year).

4. 4
   Sign a DPA

   Have a Data Processing Agreement with Google LLC covering the data this cookie collects.

5. 5
   Verify it works

   In a private window, reject cookies and confirm __Secure-3PSIDCC is not set.
