Learn how to add banner, interstitial, and rewarded ads to your WebToApp-converted Android app using Google AdMob. Start earning revenue from your app.
Making Money From Your App
You've converted your website into an Android app. Now you want to earn money from it. Google AdMob is the most popular mobile ad network, used by millions of apps worldwide.
WebToApp makes AdMob integration simple — just enter your ad unit IDs and choose where ads appear.
What Is Google AdMob?
AdMob is Google's mobile advertising platform. It connects app developers with advertisers. You show ads in your app, and Google pays you a share of the ad revenue.
AdMob supports several ad formats:
Banner Ads
Small rectangular ads that sit at the top or bottom of the screen. They're always visible and generate steady revenue.
- Best for: Content apps, news readers, utility apps
- Typical eCPM: $0.50-$3.00
Interstitial Ads
Full-screen ads that appear at natural transition points (e.g., between pages). They have higher engagement and revenue.
- Best for: Apps with natural break points
- Typical eCPM: $5.00-$15.00
Rewarded Ads
Users watch a video ad in exchange for something (premium content, virtual currency, etc.). Highest revenue per impression.
- Best for: Apps with premium content or gamification
- Typical eCPM: $10.00-$30.00
Setting Up AdMob with WebToApp
Step 1: Create an AdMob Account
1. Visit AdMob
2. Sign in with your Google account
3. Complete the setup wizard
Step 2: Create Ad Units
1. Click "Apps" → "Add app"
2. Search for your app or add it manually
3. Create ad units for each format you want:
- Banner ad unit
- Interstitial ad unit
- Rewarded ad unit
4. Copy the ad unit IDs (format: ca-app-pub-XXXXX/YYYYY)
Step 3: Configure in WebToApp
In the WebToApp app wizard:
1. Enable "AdMob Integration"
2. Paste your Banner Ad Unit ID
3. Choose banner position (top or bottom)
4. Optionally add Interstitial Ad Unit ID
5. Set interstitial frequency (e.g., show after every 3 page loads)
Step 4: Build and Test
Build your app and test that ads appear correctly. Use AdMob test IDs first, then switch to real IDs before publishing.
Revenue Expectations
Ad revenue depends on many factors:
- Geography: US/UK users generate 5-10x more than India/SEA
- Niche: Finance and insurance apps earn more than entertainment
- User engagement: More time in app = more ad impressions
Rough estimates for a WebToApp-converted app:
| Daily Active Users | Estimated Monthly Revenue |
|-------------------|--------------------------|
| 100 | $5-$20 |
| 1,000 | $50-$200 |
| 10,000 | $500-$2,000 |
| 100,000 | $5,000-$20,000 |
Best Practices
1. Don't overdo it — Too many ads drive users away
2. Place ads at natural break points — Don't interrupt user flow
3. Use banner + interstitial combo — Steady revenue with occasional higher payouts
4. Respect the user — Never show ads immediately on app open
5. A/B test placements — Try different positions and frequencies
6. Follow AdMob policies — Never click your own ads or encourage users to click
