## What is a Campaign?

A **Campaign** is the basic unit of ad delivery. Advertisers select an ad product sold by publishers, set their desired period and budget, and book a campaign. Once the campaign is approved, creatives are registered, and ads are displayed when the start date arrives.

### Campaign Workflow

Campaigns progress through the following stages from booking to ad display.

| Stage                        | Responsible | Description                                            |
| ---------------------------- | ----------- | ------------------------------------------------------ |
| **1. Campaign Booking**      | Advertiser  | Select ad product, set period/budget, choose targeting |
| **2. Payment & Submit**      | Advertiser  | Enter payment information, agree to terms, and submit  |
| **3. Campaign Review**       | Publisher   | Review campaign content and approve/reject             |
| **4. Creative Registration** | Advertiser  | Upload image/video creatives, set landing URL          |
| **5. Creative Review**       | Publisher   | Review creative content and approve/reject             |
| **6. Ad Display**            | System      | Automatically display from start date to end date      |

<Note>Creatives can be registered at the same time as campaign submission, or separately after campaign approval. Both the campaign and creatives must be approved for ads to be displayed.</Note>
