Google Advertising ID

The Google Advertising ID (GAID) is a unique string aiding in mobile app user identification for advertising purposes.

Google Advertising ID (GAID) is a unique, resettable ID for advertising, provided by Google Play services. It gives users better controls and provides developers with a simple, standard system to continue to monetize their apps. This user-specific, unique, and resettable ID for advertising on Android devices is used to track user's activity and deliver personalized ads.

In other words, every time an Android user downloads an app or makes a purchase, the GAID relays that user behavioral data to ad networks, making it easier for marketers to track activity and user engagement. This has proven instrumental in ecommerce, enabling businesses and advertisers to strengthen their digital advertising strategies.


Let's say an eCommerce business has launched a mobile app. Every fresh installation of this app by an Android user will generate a unique GAID. Each time this particular user interacts within the app or completes a transaction, their GAID is sent along with this behavioral data to specific ad networks, allowing the business to personalize future ad targets to this user.

Why is Google Advertising ID important?

The Google Advertising ID enables precise targeting and an increased personalization level, resulting in superior user experiences. Businesses can track and target users based on their interactions or transactions, and effectively optimize advertising campaigns. This leads to better conversions, improved ad relevance, and a higher revenue generation potential.

Which factors impact Google Advertising ID?

The effectiveness of the GAID is significantly influenced by how businesses use it. Businesses can improve GAID utilization by:

  • Properly integrating it into their analytics toolkit to track user activity.
  • Using it in conjunction with other data to develop better audience segmentation and targeted marketing strategies.
  • Staying updated with Google's policies & respecting user privacy norms to maintain usage compliance.

How can Google Advertising ID be improved?

The primary factor impacting GAID effectiveness is user reset behavior. Users can reset their GAID anytime, disrupting user history tracking and potential personalization of ads.

What is Google Advertising ID's relationship with other metrics?

GAID provides greater insights when combined with other ecommerce metrics. For example, in conjunction with metrics like average order value (AOV), it helps identify high-value customers. By combining GAID with conversion rate, businesses can differentiate users based on purchase behaviour, allowing for refined targeting and improved personalization.
