It’s possible to earn from AdMob without publishing your app on the Play Store, but it may be more challenging. The Play Store is a popular app store with a large user base, which can make it easier to reach a wider audience and generate more ad impressions and clicks.
If you don’t want to publish your app on the Play Store, you’ll need to find other ways to distribute your app and generate ad impressions. This may involve using alternative app stores, distributing your app through your own website, or using other channels to promote your app.
It’s worth noting that publishing your app on the Play Store can help increase the visibility and credibility of your app, which may make it easier to generate ad impressions and clicks. Additionally, the Play Store has policies in place to ensure that apps are of high quality and meet certain standards, which can help increase the likelihood that users will engage with your app and ads.
Overall, while it is possible to earn from AdMob without publishing on the Play Store, it may be more challenging and may require you to find alternative ways to promote and distribute your app.
