Incorrect trigger in GTM

Description

One or more tags are being fired before consent has been initialized or are using an inappropriate trigger in Google Tag Manager. This may prevent the CMP from sending the default or update signals in time, which undermines the effectiveness of Google Consent Mode.

Main cause

• The trigger used for the CMP tag (or Consent Mode setup) is not "Consent Initialization" (gtm.init), or

• Other tags are firing before or alongside the gtm.init event.

What to do

• In Google Tag Manager, open your CMP tag (e.g., ABconsent – Sirdata CMP) ;

• Make sure it uses only the trigger "Consent Initialization" (gtm.init) ;

• Ensure that no other tags are fired using this trigger or before it ;

• Do not fire any Google tags (Analytics, Ads, etc.) before this event occurs.
