A Placement is meant to represent your app or website. It indicates the platform that your owned & operated asset is build for and running on.
A Placement can be one of the following:
Android App
iOS App
Website
Network / API
For example, you create a separate Placement for your Android App and a separate Placement for your IOS app.
React Native Example
If you created an app via React Native and you compile your production version for both Android and IOS, you would ideally set up the following placement on ayeT-Studios:
Android App
iOS App
Once you create a Placement, you cannot change the platform type
While creating a Placement, you also set up the AdSlot, which you select based on the type of integration or ad format you want to use.
