Ionic Launch Event. September 28th 2021.
Many consumer apps need to display ads in order to generate revenue.
The most popular ad network for mobile apps is Google Admob, and there is a community-maintained Capacitor plugin ready to use:
npm install @capacitor-community/admob npx cap update
Then, follow the Capacitor Community Admob documentation for configuration and usage.
This community article is also a useful reference for practical applications of this plugin (though it is using an older version of the plugin).
