What type of asset is not permitted when creating an app campaign?

In the context of app campaigns, a website asset is not permitted since the primary focus is on promoting the app itself rather than directing traffic to a separate website. App campaigns primarily utilize app-related assets to drive installs and engagement directly within app stores. Video content, app store links, and promotional copy are all valid assets because they directly support the goal of showcasing the app and enticing potential users to download it. Each of these asset types can effectively illustrate features of the app or provide direct links to the app store, ensuring that the advertising efforts are streamlined and focused on app installations. Thus, excluding a website aligns with the goal of maintaining a focused and app-centric campaign.
