The Aggregation Service can support a variety of use cases, including:
| Use case | Description | Example |
|---|---|---|
| Attribution Reporting API | The Aggregation Service is essential for processing data from the Attribution Reporting API, enabling measurement of ad campaign performance without relying on cross-site tracking.. | Let’s say an advertiser wants to measure how many users purchased a product after viewing their ad campaign. The Attribution Reporting API collects data on ad views and conversions, while the Aggregation Service processes that data to provide aggregated and anonymized reports on campaign performance without revealing individual user information. |
| Private Aggregation API | The service securely handles data from the Private Aggregation API, allowing for the measurement of metrics like unique reach, frequency, and demographics while protecting user privacy. | A publisher wants to understand the demographics of users who visit their website. The Private Aggregation API, in conjunction with the Shared Storage API, collects data on user demographics. The Aggregation Service processes this data to provide aggregated insights into age ranges, gender distribution, and other demographics without compromising individual privacy. |
| Campaign optimization | By providing aggregated and anonymized insights, the Aggregation Service helps advertisers and publishers optimize their campaigns, allocate budgets effectively, and improve overall ad performance. | An ad tech provider wants to help their clients optimize ad spending. By utilizing the Attribution Reporting and Private Aggregation APIs, they collect data on ad performance and audience behavior. The Aggregation Service processes this data to provide aggregated insights, enabling the ad tech provider to recommend adjustments to bidding strategies, targeting parameters, and ad creatives that can improve campaign effectiveness. |
