AdMob & Monetization

Google AdMob lets you earn revenue by displaying ads in your app. You add AdMob by asking Primio’s AI to build each piece in the chat — consent flow, banner ads, and interstitial ads cover the most common setup.

Setup order

The order matters. You must implement the consent flow before adding any ad units.

1. Consent flow (required first)

   Ask the AI to add a GDPR/ATT consent flow using Google’s User Messaging Platform. This shows a consent dialog on first launch asking users for permission to show personalized ads, and gates ad loading on their choice.

2. Banner ads

   Ask the AI to add an AdMob banner ad using test ad unit IDs. This adds a persistent ad banner, typically at the bottom of a screen — name the screen you want it on.

3. Interstitial ads

   Ask the AI to add an AdMob interstitial ad using test ad unit IDs. This adds full-screen ads that appear at natural transition points (between screens, after completing an action) — tell it where those points are in your app.

Caution

Always implement the consent flow before adding any ad units. Showing ads without consent to EU users violates GDPR and can result in your AdMob account being suspended.

Creating an AdMob account

1. Sign up at admob.google.com

   Use your Google account. AdMob will ask for payment information to pay you earnings.

2. Create an app in AdMob

   Add your app (you can do this before it’s published — select “No, I haven’t published it yet”).

3. Create ad units

   Create the ad units you need: banner, interstitial, rewarded, etc. Each unit gets a unique ID.

4. Note your ad unit IDs

   You’ll need these to replace the test IDs in your app before publishing.

Replacing test IDs with real ones

Ask for test ad unit IDs while you build. These show placeholder ads during development but generate no revenue.

Before publishing, replace them with your real AdMob ad unit IDs:

“Replace the test AdMob ad unit IDs with my real IDs: banner: ca-app-pub-xxx/yyy, interstitial: ca-app-pub-xxx/zzz”

Caution

Two common mistakes to avoid: publishing with test IDs (you won’t earn anything) and clicking your own real ads (Google will suspend your account). Always verify that real IDs are in place before your production build.

Other monetization options

Ads aren’t the only way to monetize. You can ask Primio to add other revenue models:

In-app purchases:

• “Add a premium upgrade that removes ads for $2.99”
• “Add a one-time purchase to unlock all themes”

Subscriptions:

• “Add a monthly subscription for premium features”
• “Add a free trial with a weekly subscription”

Paywalls:

• “Show a paywall after the user has used the app 3 times”
• “Lock premium recipes behind a subscription”

Note

In-app purchases and subscriptions require additional setup in Google Play Console and/or App Store Connect. The AI can generate the Flutter code, but you’ll need to configure products and pricing in the store dashboards separately.
