How does Littledata work with Google Consent Mode?
Littledata integrates automatically and seamlessly with Consent Mode v2 via Shopify Customer Privacy API. This includes Advanced Consent Mode, sending cookieless pings to Google servers even if the user does not accept consent, so Google can better model and predict your non-consenting traffic.
Most Shopify cookie banners and some Consent Management Platforms (CMPs) support this Customer Privacy API.
For Consent Mode to work you must have a cookie banner. You can set it up from your Shopify Admin by going to Settings -> Customer Privacy -> Cookie Banner, or use another banner app that is compliant with Shopify Customer Privacy API.
Mapping of Shopify consent types to Google
Shopify’s Customer Privacy API supports four consent types.Google Consent Mode v2 tracks customer consent as four different properties, which switch their state depending on the preferences that the customer has chosen within the Shopify cookie banner or CMP:
| Google Consent Mode Parameter | Shopify Consent Type |
|---|---|
ad_storage = granted | marketing = yes |
ad_user_data = granted | marketing = yes |
ad_personalization = granted | marketing = yes |
analytics_storage = granted | analytics = yes |
The first 3 parameters (those that pertain to advertising) will change their status when marketing consent is accepted or denied, while the last parameter will change based on analytics consent.
Depending on what the user has accepted or declined, a consent update could look like this:
Consent Mode v2 adds 2 new parameters to the consent states, those being:“ad_user_data” and “ad_personalization”.
Advanced Consent Mode and Modeling
Unlike Basic Consent Mode, which only allows data collection from users who explicitly grant consent, the Advanced Mode collects data from users who do not grant explicit consent, thus enabling a more comprehensive data collection process. To go more in-depth here's an article on how to check if a website implements Google Consent Mode V2 properly.
When consent is denied, the Google Analytics library will still load and send events, but these will be sent as cookieless pings. This allows Google to collect and model data without relying on cookies, ensuring compliance with user consent choices while still enabling valuable insights through advanced data modeling.
This modeling includes Google Ads consent mode modeling, Google Ads online modeling, Google Analytics conversion modeling, and Google Analytics behavioral modeling.
With Advanced Consent Mode store owners can rest assured that their tracking efforts are in line with privacy standards while still being able to obtain valuable information about their users. This is a significant step forward in data tracking and privacy.
