In-app advertising means your ad appears inside someone else's mobile app — a game, a weather app, a news reader, a utility. The user is scrolling through an app, and your ad shows up as a banner, interstitial, or video.
It's one of the most widespread forms of digital advertising (over 50% of all digital ad spend now flows through mobile), but it's often misunderstood by local businesses.
This guide cuts through the noise: when in-app advertising works for local businesses, when it doesn't, and how to spend your budget without wasting it.
How In-App Advertising Works
When you run ads through networks like Google's Display Network, Meta Audience Network, or dedicated mobile ad networks, a portion of your impressions will be served inside mobile apps.
You don't usually control which specific apps your ads appear in (unless you use placement targeting). You target audiences — based on demographics, location, interests, or behaviour — and the network places your ad where those users are.
The ad formats vary:
Banner ads — horizontal strips at the top or bottom of the screen
Interstitials — full-screen ads that appear between content
Rewarded video — users opt in to watch a video in exchange for in-app currency (common in games)
Native ads — ads that blend into the app's content style
For local businesses, banner ads and interstitials are most common. Rewarded video is primarily a gaming ad format.

Who Should Use In-App Advertising
In-app advertising is not the right channel for every local business. Here's when it makes sense:
Local businesses targeting mobile-heavy audiences
If your customers are predominantly on mobile — and for most local services, they are — in-app ads let you reach them in the moments between searching. A gym ad appearing in a fitness tracking app, a coffee shop ad in a morning news app, a salon ad in a beauty content app. Context matters for ad relevance.
Brand awareness campaigns on tight budgets
In-app CPMs (cost per thousand impressions) are often significantly lower than Google Search or Meta Ads CPCs. If your goal is local brand visibility — getting your name in front of people in your area repeatedly — in-app display can deliver high impression volume affordably.
Retargeting campaigns
When combined with your website or Google Ads retargeting lists, in-app networks let you follow up with people who visited your website or engaged with your Google Ads but didn't convert. These warm audiences convert at much higher rates than cold traffic.
Seasonal or event-driven awareness
Launching a new location? Running a limited-time offer? In-app display campaigns can spike awareness quickly and locally in a way that takes weeks to achieve through organic channels.
Who Should NOT Use In-App Advertising
Emergency service businesses. If your customers need you now (plumbers, electricians, locksmiths), they're searching Google — not tapping a banner ad in a game. Your budget belongs in Google Search Ads.
Low-awareness categories. If people don't know they need what you offer until they're actively searching, display advertising (including in-app) creates weak demand. Search advertising captures existing demand.
Businesses without strong brand visuals. In-app ads are visual. A strong logo, brand colours, and a clean image matter. A text-heavy banner in a mobile app doesn't convert.
Watch Out
In-app banner ads have very high rates of accidental clicks — users tapping an ad while trying to scroll or close it. Always use click-through rates alongside conversion tracking, not just clicks. Set up proper conversion tracking before spending on in-app ads.
The Main In-App Advertising Networks
Google Display Network / AdMob
Google's Display Network includes millions of apps that run Google's AdMob ad platform. When you run Google Display Ads, your ads automatically appear in these apps alongside websites.
Best for: Local businesses already using Google Ads who want to extend reach to mobile apps. Easy to add to an existing Google Ads account. Strong audience targeting using Google's first-party data.
Minimum budget: No strict minimum — $10–$20/day generates meaningful data.
Meta Audience Network
When you run Meta (Facebook/Instagram) Ads, your campaigns can extend to the Audience Network — a collection of apps and websites outside Facebook that Meta has partnered with.
Best for: Businesses already running Meta Ads who want to extend reach beyond the Facebook/Instagram feeds. Same audience targeting applies (location, age, interests, custom audiences).
Note: Meta has reduced Audience Network transparency in recent years. Monitor your placement breakdown in Meta Ads Manager and exclude app placements if results are poor.
Apple Advertising (Search Ads + Display)
Apple's advertising platform covers the App Store and, more recently, Apple News and Apple Stocks. Targeting uses Apple's privacy-respecting approach — no third-party tracking, demographic targeting only.
Best for: Businesses targeting affluent iOS users in premium content environments. CPMs are higher than Google or Meta but audience quality is strong.
Independent Mobile Ad Networks
Platforms like Unity Ads (gaming focus), ironSource (gaming/entertainment), and AppLovin (mobile gaming and apps) specialise in in-app advertising — particularly in gaming apps, which have massive mobile audiences.
For local businesses: These networks are generally less relevant unless you're specifically trying to reach mobile gamers. The contextual relevance for local services is weak in gaming environments.

What In-App Ads Actually Cost
In-app advertising is priced on CPM (cost per thousand impressions) rather than CPC for most formats.
Google Display / AdMob: $0.50–$3.00 CPM for local targeting
Meta Audience Network: $1–$5 CPM
Apple Advertising: $3–$8 CPM
Interstitials: 2–5× higher CPM than banners, but higher engagement
For a local business running a $500/month awareness campaign:
At $1.50 CPM: ~333,000 impressions per month
Targeting a 10-mile radius around your location: meaningful local saturation
The key insight: in-app advertising is inexpensive per impression. The challenge is converting those impressions into actions. Click-through rates on mobile banner ads average 0.05–0.3% — far lower than search ads.
Setting Up In-App Campaigns
The easiest path for most local businesses is through networks you already use:
Via Google Ads:
Create a Display campaign
Select "Mobile apps" under targeting
Target by location (radius around your business), demographic, and interests
Use responsive display ads — upload logos, images, and text; Google assembles the ad
Via Meta Ads:
Create a campaign with Traffic or Awareness objective
At the ad set level, select "Automatic placements" (includes Audience Network) or manually add it
Use existing creative from your Facebook/Instagram campaigns — Meta adapts them for the Audience Network
Monitoring:
Check the placement report weekly
Exclude placements with high CTR but zero conversions (often accidental clicks)
Prioritise placements with demonstrated conversion activity
In-App vs Search Ads: Which Comes First?
For most local businesses: search ads first, always.
Google Search Ads capture people who are actively looking for what you offer. In-app display ads reach people who may or may not ever need your service. The intent gap is enormous.
The right time to add in-app advertising:
You're running Google Search Ads and have profitable campaigns
You want to build local brand awareness alongside your intent-based campaigns
You're retargeting people who already visited your site or engaged with your ads
You have seasonal volume to amplify
In-app advertising amplifies demand; search advertising captures it. Build your search foundation first.
The Honest Verdict
In-app advertising is a legitimate channel for local businesses — but it's a supporting player, not the headline act.
It works well for: brand awareness, retargeting warm audiences, and cost-efficient impression volume in local markets.
It works poorly for: emergency services, high-intent conversions, and categories where people actively search rather than browse.
If you're spending $1,000+/month on Google Search Ads and Meta Ads, adding $200–$500/month of in-app display for awareness and retargeting is a reasonable experiment. If you're spending under $1,000/month total, that budget goes further in search.

Frequently Asked Questions
Q: I own a pizza shop. Will in-app ads get people to order delivery?
It depends on how you set them up. If you run a banner inside a game, probably not — people aren’t hungry while playing Candy Crush. But if you target the "food delivery" interest within Google Display Network and run a native ad inside a local news app around lunchtime, yes. I had a pizza shop in Chicago do exactly that: they spent $400/month and got 60 orders in six weeks using a "buy one large, get a small free" offer. The key is timing and a clear call-to-action that links directly to your Square online ordering page.
Q: How much do in-app ads cost per click?
For local businesses, expect $0.50 to $2.00 per click on GDN, depending on the competition in your city and the app category. Weather apps tend to be cheaper; finance apps are more expensive. But don’t focus on click cost — focus on cost per lead or cost per visit. A cheap click that doesn’t convert is more expensive than a $2 click that books an appointment.
Q: Do in-app ads work for professional services like lawyers or dentists?
They can, but you need to be very careful. People in apps are usually not in a “find a lawyer” mindset. I’ve seen it work for dentists who run “new patient special” ads inside health and wellness apps. A dentist in Nashville spent $500/month on native ads inside a calorie-tracking app and got 12 new patient calls in a month — cost per call was $42, which was cheaper than their Google Ads average of $65. But it only worked because the app matched the audience (people interested in health). For a divorce lawyer? Probably not.
Q: Should I use rewarded video ads for my local business?
Rarely. Rewarded video is when a user watches an entire ad in exchange for an in-app reward (like extra lives in a game). It works for gaming apps and some e-commerce (like mobile game offers). For a local coffee shop, gym, or salon, the cost per completed view is often $0.10–$0.20, but the conversion rate is low because the user is focused on the game. I’d only test it if you have a super compelling offer (e.g., “watch this 30-second video for a free drink”) and can track redemption with a code. Otherwise, skip it.
Q: How do I track in-app ad results if I don’t have a website?
If you don’t have a website, you’re limited. You can use a call-only ad campaign (where the ad shows a phone number and tapping calls directly). Google Ads and Meta both support call-only formats for in-app placements. You’ll need call tracking to know which calls came from which ad. Another option is to use a unique promo code (e.g., “show this ad for 10% off”) and track redemptions manually. I’ve done this for a bakery in Portland — they printed the promo code on a small sign in-store and asked customers how they heard about them. Not perfect, but better than nothing.
Q: What’s the minimum budget I should test?
For a single city, don’t spend less than $200 per month on one network. Any lower, and you won’t get enough data to see a trend. $300 is better. Run it for two months, then decide to scale or cut. I’ve seen businesses waste $50/month on ads that never delivered a single impression because the budget was too low to win auctions.
Closing paragraph
I’ve been in rooms where agencies pitched in-app ads as a magic bullet for local businesses. It’s not. It’s a tool — and like any tool, it works when you use it correctly. The businesses that see real returns are the ones who test with discipline, track everything, and don’t abandon their other channels. I still remember a salon owner in Austin who told me after six months of careful testing: “I finally feel like I’m spending my ad budget, not burning it.” That’s the goal. If you want to talk through whether in-app ads make sense for your specific business — or if you’re already running them and wondering why they’re not working — I’m happy to take a look.
