GDPR compliance is not a choice but a must for webmasters to ensure the privacy and security of user data. The implementation of cookie consent according to Google Consent v2 policy is a crucial step in this process. For more info on this, visit the EU GDPR Information Portal.

Let’s look at how to set up cookie consent using Google Tag Manager and how to create a centre popup feature on CookieYES (for free!).

What is Google Consent Mode v2?

Google Consent v2 policy requires websites to obtain user consent before collecting data through cookies. This ensures that users are informed about data collection practices and can control their personal information. For a detailed overview, check out Google Consent Mode v2 Overview.

Google Consent Mode V2 introduces 2 new consent stats: ‘ad_user_data’ and ‘ad_personalisation’

  • ‘ad_user_data’ determines whether the user consents to sending advertising-related user data to Google
  • ‘ad_personalisation’ controls if data can be used for personalised ads, like remarketing.

These two new parameters are in addition to the current ‘ad_storage’ and ‘analytics_storage’ parameters.

What happens if you don’t set up Google Consent Mode v2?

If Google Consent Mode v2 is not implemented, several issues may arise.

Without consent for personalised advertising, ads become less targeted and, consequently, less effective. This lack of targeting can lead to lower conversion rates, as the ads are not tailored to the users’ interests and behaviours.
