AdMob Ads in Your App,
Added With One Prompt
Describe the app, tell the AI which AdMob ads you want and where they go, then test them on your phone before you publish to the App Store and Google Play.
How do I add AdMob ads to my app?
Create a free AdMob account and one ad unit per ad format, then tell Fastshot which ads you want and where they go: banner, interstitial or rewarded. The AI writes the ad code into your React Native and Expo app for iPhone and Android. Test with Google's test ads, then build the app to your phone and add your own ad unit IDs.

What AdMob is and how it pays
AdMob is Google's ad network for mobile apps. You make room for ads in your app, advertisers compete for that room in an auction, and Google pays you for the ads your users see. Google closed its AdMob acquisition on May 27, 2010, and AdMob itself is free to use.
The room for an ad is called an ad unit. Each ad unit has a format, such as banner or rewarded, and your app asks AdMob to fill it whenever the ad should show. Advertisers pay different prices for different ads, so what you earn per thousand views depends on the format, the country and the audience. There is no fixed rate, and your own AdMob dashboard is the only place that shows your real numbers.
AdMob pays on a monthly cycle. Earnings are finalized at the start of the next month, and the payment goes out around the 21st once your balance is over the payment threshold. A smaller balance rolls into the following month. AdSense is the sister product for websites, so an app uses AdMob.
On Fastshot you do not write the integration by hand. You ask for ads in chat and the AI writes the code for iOS and Android. For the whole list of ways to earn from an app, read how to monetize an app.
What Fastshot builds for AdMob
Ask in plain words. The AI decides the screen layout and ties each ad to the right moment.
Banner ads on scrolling screens
A strip at the top or bottom of a screen. It suits places where people scroll, such as a feed, a search page, a recipe list or a level list.
Interstitial ads at natural breaks
Full-screen ads that appear between actions, for example after a finished level, a saved entry or a completed lesson. Tell the AI how often, such as after every third task.
Rewarded ads that unlock something
The user chooses to watch a short video and gets a reward back: an extra life, a hint, double coins or a day of premium themes. The AI builds the button, the ad call and the reward logic together.
Ads next to a subscription
Run a free tier with ads and a paid tier without them. Ask the AI to hide every ad for subscribers, and add the purchase with Adapty or RevenueCat.
Your own AdMob IDs
When the AI asks how ads should work, choose AdMob with your own IDs. Real ads from your AdMob account then run in the installed app, and the earnings go to you.
The screens around the ads
A "Watch an ad for a hint" button, a thank-you message after the reward and the empty slot when no ad is ready. The ad moment feels like part of the app.
Prompts that add AdMob ads
Copy these into the Fastshot chat and change the screens to match your app.
Build a word puzzle app with daily levels and a hint button.
Add AdMob ads:
- A banner at the bottom of the level list.
- An interstitial after every third finished level, never in the middle of a level.
- A "Watch an ad for a hint" button that plays a rewarded ad and gives one hint when the video ends.
Hide all ads for users who buy the premium subscription.Add AdMob ads step by step
Create your AdMob account and ad units
Sign up at admob.google.com with a Google account, add your app, and create one ad unit for each format you want: banner, interstitial and rewarded. Every ad unit gets its own ID. Keep them for step 4.
Describe the app and mention the ads
Write the app prompt in Fastshot and say you want ads, or add them after the first version is ready. Answer the one or two questions the AI asks. When it asks how ads should be handled, pick AdMob with your own IDs.
Say where each ad goes
Name the screen and the moment: banner at the bottom of Home, interstitial after level three, rewarded button inside the hint dialog. Approve the plan and the AI builds the screens and the ad calls.
Test with Google test ads, then add your IDs
Use Google's test ads while you build, because clicking your own live ads is not allowed and Google can close an account for it. When the layout is right, send the AI your ad unit IDs, for example "Use this ID for the Home banner."
Build to your phone and check every slot
Build the app and open it on a real device. Check that each ad sits where you asked, that the rewarded button gives its reward, and that subscribers see no ads.
Publish and get paid
Publish to the App Store and Google Play with your own Apple Developer account ($99 a year) and Google Play account ($25 one-time). See do you need an Apple Developer account for the iPhone side. AdMob pays out monthly once your balance passes the threshold.
AdMob ad formats at a glance
Pick the format by the moment in your app, then say that moment to the AI.
| Format | Where it appears | Good for | What to tell the AI |
|---|---|---|---|
| Banner | Top or bottom of a screen | Feeds, lists and search results where people scroll | "Add a banner at the bottom of Home." |
| Interstitial | Full screen between two actions | Natural breaks such as a finished level or a saved entry | "Show an interstitial after every third level." |
| Rewarded | Full screen, started by the user | Free users who want a hint, a life or bonus coins | "Add a button that plays a rewarded ad for one hint." |
AdMob rules that protect your account
Never click your own live ads and never ask friends to. Google treats it as invalid activity, and a closed AdMob account can also block you from AdSense. Test ads exist so you can tap freely while you build.
Google ads cannot run in an app that promises payment to users who click or view ads. A rewarded ad should give an in-app reward such as a hint or coins, not cash for watching.
AdMob lets you block advertisers and ad categories, and its ad review center lets you look at individual ads. If an ad does not fit your app, block it there instead of removing the ad slot.

Frequently Asked Questions
How much does AdMob pay per 1,000 impressions?
There is no fixed rate. Google says advertisers pay different prices for different ads, so earnings vary by ad format, country and audience. Your AdMob dashboard shows the real figure for your own app after the first ads run.
Does AdMob cost money to use?
No. Google describes AdMob as a free platform. You earn money from the ads shown in your app, and you pay Apple $99 a year and Google $25 one-time only for the developer accounts that let you publish.
Who owns AdMob?
Google. It closed the AdMob acquisition on May 27, 2010, and AdMob now sits next to AdSense and Ad Manager in its publisher products. AdMob is the one made for mobile apps.
How do I make money with AdMob?
Show ads in an app people open often. Create ad units in AdMob, place banner, interstitial or rewarded ads at sensible moments, and let the auction fill them. In Fastshot you ask the AI to add the ads and describe where they go.
Should an app use AdMob or AdSense?
AdMob. Google makes AdMob for mobile apps and AdSense for websites. A Fastshot app is a native iOS and Android app, so you set up ad units in AdMob.
How often does AdMob pay?
Once a month. Earnings are finalized early in the next month and payment goes out around the 21st when your balance is over the threshold. A balance under the threshold rolls into the next month.
Can I pay users to watch ads in my app?
Not with real money. Google ads may not run on apps that promise payment to users who click or view ads. Rewarded ads should give in-app rewards, such as a hint, an extra life or coins you define yourself.
Do I need to code to add AdMob ads with Fastshot?
No. You ask the AI in chat, for example "add a banner to Home and a rewarded ad for hints," and it writes the React Native code. You only create the AdMob account and ad units yourself.
