Final answer:
To add a banner ad to your app, you need to work with an advertising network that serves ads to mobile devices. The ad network manages ad display and targeting, and compensation is based on ad engagement metrics such as clicks or impressions.
Step-by-step explanation:
To add a banner ad to an app, a developer needs to integrate an advertising network's SDK, which connects advertisers to apps.
An advertising network, sometimes referred to as an ad network, is a service that connects advertisers to websites that want to host advertisements.
The main purpose of an ad network is to aggregate ad space supply from publishers and matching it with advertiser demand.
The process involves integrating the ad network's SDK (Software Development Kit) onto your app, which allows for the serving of ads. Once integrated, you can control where and how often ads are displayed in your app.
Compensation usually depends on the amount of clicks or impressions your ads receive.
Selecting the right ad network is crucial, as it affects the type of ads that will be shown and can have an impact on the user experience.
Some ad networks use real-time bidding (RTB) to show ads that are more targeted to your user base, whereas others might offer different options based on cost-per-click (CPC) or cost-per-impression (CPM) models.
