## How We Use Google Ads

We run **Google Ads App Campaigns (UAC)** to acquire users for our published apps. Our primary campaigns target Korean-speaking users, with plans to expand to Japan and Taiwan markets.

## Google Ads API Usage

We are building an **internal reporting tool** that connects to the Google Ads API for the following purposes:

- **Daily Performance Reports**: Automatically retrieve campaign metrics (impressions, clicks, cost, installs, CPI) on a daily basis

- **Revenue Comparison**: Compare Google Ads acquisition cost with AdMob ad revenue to calculate net ROI per user

- **Asset Performance Tracking**: Monitor ad creative (headline/description) performance labels (BEST/GOOD/LOW) to optimize campaigns

### Technical Details

- **Access Type**: Read-only reporting (no campaign creation or modification via API)

- **API Methods**: `GoogleAdsService.SearchStream` for GAQL queries

- **Usage Volume**: Fewer than 50 API calls per day

- **Users**: Internal only (single developer/account owner)
