Details

The Google Advertising Identifier (GAID) is a crucial component for mobile advertisers and developers. It allows for the tracking of user interactions with ads on Android devices while maintaining user privacy. GAID can be reset by users, providing a balance between effective ad targeting and user control. Developers can access GAID through the Google Play services API, ensuring that ads are relevant and personalized without compromising user data.

In practice, GAID is used to attribute ad clicks and impressions to specific user actions, such as app installs or in-app purchases. This helps advertisers optimize their campaigns by understanding which ads perform best and how users interact with them. Additionally, GAID supports cross-device tracking, allowing advertisers to follow user journeys across multiple devices.

Examples & formulas

For instance, an advertiser might use GAID to measure the conversion rate of a specific ad campaign by comparing the number of ad clicks to the number of app installs.

Conversion Rate = (Number of Installs / Number of Clicks) * 100

Common mistakes

Not resetting GAID regularly can lead to inaccurate tracking; encourage users to reset periodically.
Relying solely on GAID for attribution can miss multi-touch points; consider using it alongside other identifiers.
