## Overview  
**Ad Capping** refers to the automatic stopping of a Flight upon hitting a certain metric.

For instance, you may want to have a Flight stop showing ads once it hits 10M impressions. Or, you may have promised 5K clicks to an advertiser, and want it to automatically turn-off when it hits it.

## What You Can Cap On  
Ad Capping is set at the **Flight** level. The exception is for ad capping using revenue budgets (see below for more info on that).

You set them at the **Daily** and/or **Lifetime** level and can cap by **Impressions**, **Clicks**, **Conversions**, or **Revenue**.

> 👍  
> Lifetime caps apply to the entire history of the ad/flight/etc. If you need to increase the cap of a flight etc. that has hit its cap, you will need to set the new cap as the old cap plus the additional cap amount.

## Setting Caps  
**Cap Type** is where you set the target metric, and **Daily** and **Lifetime** are where you set the target amount.

## Budget Capping  
Budget caps (or revenue caps) will stop an ad from serving once a budget is reached. For example, if a flight is priced at $1.00 CPM and the budget is $1000, the flight will stop serving when Kevel records 1 million impressions.

The budget can be set on advertiser, campaign, or flight objects.

Budget caps also work for second-price auctions and RTB flights where there isn't a steady stream of revenue per event.

> 📘  
> We will respect the most restrictive budgets. For example, if the budget for an advertiser is $5000 but the Flight budget is $1K, we will stop at $1K.

> 📘  
> Budget caps do not work with flat-rate flights. Also, flat-rate prices will be ignored in a campaign or advertiser's overall budget.

> 📘  
> When using daily revenue goals, the daily cap will automatically be calculated on the backend. A manually entered daily budget cap will be ignored.
