## Campaigns Overview

The Campaigns Tab contains the settings for Advertisers, Campaigns, Flights, Creatives, and Ads.

**[Advertisers](https://dev.kevel.co/docs/advertisers)** = The advertisers who are paying money to show ads on your site, like Nike. Your company can also be an advertiser if you are showing in-house content.

**[Campaigns](https://dev.kevel.co/docs/campaigns)** = A collection of Flights grouped around a theme, like "Nike Christmas Campaign".

**[Flights](https://dev.kevel.co/docs/flights)** = A collection of Ads. Most targeting is done at this level, so you'll likely have more Flights than Campaigns.

**[Creatives](https://dev.kevel.co/docs/creatives)** = Refers to details associated with the creative itself, like format, click URL, and the image file. A Creative by itself is not tied to a Campaign/Flight. The same Creative can be tied to multiple Flights.

**[Ads](https://dev.kevel.co/docs/ads)** = Ads are the most granular unit of Campaigns reporting. An Ad = Creative + Delivery Settings (by default it takes the Flight settings). In other words, an Ad is a Creative that has been tied to a Flight and is ready to be displayed.

Please refer to the [Service Resource and Rate Limits](https://dev.kevel.com/docs/service-level-agreement#5-service-resource-and-rate-limits) for information on the number of entities supported per network.
