## Overview

Setting a **placement limit** on an advertiser limits how often ads from that advertiser will appear in an ad request. Similar to the "Do Not Show Duplicates" feature on flights, placement limits keep a brand from becoming overexposed while still enabling them to display multiple creatives.

## Setting Up Placement Limits

To add a placement limit for an advertiser:

1. In the Advertisers list, click the pencil icon next to the name of an advertiser.
2. Check the "Limit placements per request" checkbox.
3. Enter a value greater than 0.
4. Click "Save".

To remove a placement limit, uncheck the checkbox. This means the advertiser's ads can serve on an unlimited number of placements per request.
