## Example

A skincare brand spent **\$2,400 on TikTok ads** last week targeting Gen Z audiences with influencer-style content.

| Campaign         | Add to Carts | Cost per Add to Cart |
| ---------------- | ------------ | -------------------- |
| UGC Testimonials | 847          | \$1.42               |
| Product Demo     | 312          | \$3.85               |
| Flash Sale       | 1,203        | \$0.99               |
| **Total**        | **2,362**    | **\$1.02**           |

## How It Works

TikTok counts an add-to-cart event when a user adds a product to their cart on your site after interacting with your ad. Attribution uses TikTok's click-through and view-through windows (typically 7-day click, 1-day view). The count reflects TikTok's attribution model, which may differ from Upstack's first-party attribution.
