Setting up AdMob Ads for your app – AppsGeyser Support, FAQ, Tutorials | Help Center for App Builder

This guide will walk you through the process of setting up AdMob for your app.

Open AdMob website and click "Sign up".
If you already have a Google account, log in and provide the necessary details to register for AdMob. Fill in the required fields and complete the registration by clicking on "Get Started." If you do not have a Google account, you will need to create one.
Now you will be prompted to add a new app. Remember, you can only add an app that has already been published on Google Play. If your app hasn't been published yet, now is the time to do so. Please refer to our guide: Publishing your app on Google Play: Step-by-step guide.
On the next screen, enter your App Package name and click "Search."
When you see that your app is found, click "Add".
On the next screen verify all the details and click "Add app".
Now your app is in review. App reviews typically take a couple of days but, in some cases, may require more time to evaluate your app. Ad serving is limited until the review is complete. Click "Done" to complete the process of adding your app.
The next step would be adding ad units:

Decide which type of ad unit suits your app best. You can choose between Banner ads and Interstitial ads. We recommend implementing both.

Follow the steps to add id units:
1. Click "Select" under Banner ads.
2. Enter Ad unit name and click "Create ad unit".
3. Copy banner ad unit ID.
4. Paste it to small banner ID field in Ad Network Settings section in Monetize page of AppsGeyser dashboard.
5. Return to AdMob dashboard and click "Create another ad unit".
6. Click "Select" under Interstitial ads.
7. Enter Ad unit name and click "Create ad unit".
8. Copy interstitial ad unit ID.
9. Paste it to interstitial banner ID field in Ad Network Settings section in Monetize page of AppsGeyser dashboard and click "Save changes".
10. Return to AdMob dashboard and click "Done".
