# Use conflict tags

> [!NOTE]
> ⚙️ For DOOH administrators

Use DOOH conflict tags to ensure that booking items that contain certain spots aren't played in a row.

### How conflict tags work

When working with conflict tags, keep the following in mind:

- Conflict tags allow you to control ad placement, for example, to prevent competitor ads from being shown back-to-back.
- You must first create conflict tag groups and then add conflict tags (child tags) to them.
- When creating a DOOH booking, you can only select tag groups that contain conflict tags (child tags).
- When you add a conflict tag group to a booking, all associated child tags are added automatically.
- You can add as many child tags as needed for organization.

> [!NOTE]
> Note
> 
> Only conflict tag groups are transferred to players. Even if you assign only an individual conflict tag to a booking, the associated conflict tag group is crucial for preventing back-to-back playouts.

## Create conflict tags

To create conflict tags, perform the following steps:

1. Go to **Administration > DOOH***.*

Repeat the same steps for other booking items that contain spots that shouldn't be played right after one another.
