App install ads are paid campaigns designed to drive one action: getting a user to download and open your mobile app. They run on Meta (Advantage+ app campaigns), Google (App campaigns across Search, Play, YouTube, and Display), TikTok, and Apple Search Ads, and they are billed on a cost-per-install basis that commonly runs $1 to $5 for broad consumer apps and higher for finance, subscription, or B2B apps. The single biggest lever on that cost is creative volume: the more distinct ad concepts you can test, the cheaper your installs get.
Here is how each platform's app campaigns work, what drives the cost, and the creative approach that consistently lowers cost per install.
How app install campaigns actually work
App install campaigns are unusually automated compared with normal advertising. You do not hand-pick placements or write dozens of targeted ad sets. Instead you give the network your app, a budget, a target (installs, or a deeper in-app event like a purchase or signup), and a pool of creative assets, and the machine learning decides who sees which ad where.
Because the targeting is automated, creative becomes the main thing you actually control. The algorithm optimizes by testing your assets against different audiences and doubling down on what converts. Starve it of variety and it has little to optimize with; feed it a deep, varied asset pool and it finds the pockets of cheap installs faster.
App install ads by platform
| Platform | Campaign type | Where ads show | Creative you need |
|---|---|---|---|
| Meta | Advantage+ app campaign | Facebook, Instagram feeds, Stories, Reels | 1:1, 4:5, and 9:16 images and video |
| App campaign (UAC) | Search, Play, YouTube, Display, Discover | Text, images (multiple sizes), and video | |
| TikTok | App promotion | For You feed | 9:16 native vertical |
| Apple Search Ads | Search results | Top of App Store search | Uses your App Store product page assets |
Meta and Google both reward asset breadth. Google App campaigns in particular ask for text, image, and video assets in several sizes and mix them automatically, so a thin creative pool caps how well the campaign can perform. Apple Search Ads is the exception: it largely uses the screenshots and copy from your App Store product page rather than uploaded ad creative.
What do app install ads cost?
Cost per install (CPI) is the headline number, and it varies widely. Broad consumer categories like games, utilities, and social apps often land in the $1 to $3 range on Android and higher on iOS, while finance, insurance, and subscription apps can run $5 to $15 or more because the users are worth more. Those are directional figures, not promises: your category, geography, and season move them a lot.
CPI alone is misleading, though. An install that never opens the app is worthless, so mature app teams optimize toward a cost per action deeper in the funnel, such as a registration, a first purchase, or a subscription trial. The networks can bid to those events, but only once you send them the in-app conversion data to learn from. Getting the media efficiency right over time is its own discipline, and teams that scale spend often lean on an automated media buyer to manage bids and budgets across campaigns rather than adjusting everything by hand.
Why creative is the real lever on cost per install
Once targeting is automated, the fastest way to lower CPI is to give the algorithm more good creative to choose from. App audiences fatigue quickly, a concept that crushed last month gets ignored this month, so you need a steady supply of fresh angles, not one polished hero ad. The teams with the lowest install costs are usually the ones shipping the most tests.
The blockers are volume and cost. Producing 15 to 20 distinct creative concepts, each in the feed, story, and banner sizes every network wants, is a real design bottleneck. And credit-based ad tools make heavy testing expensive by charging per generation or per download, which is exactly backwards for a channel that runs on volume.
The creative strategy that lowers CPI
A few patterns consistently win in app install creative:
- Lead with the core value in the first second. Show what the app does and why it matters immediately, in a screenshot or a single strong visual, not after a slow build.
- Show the app in a real context. Creative that places the product in a believable use case beats a bare app-store screenshot.
- Test many angles, not many colors. Different hooks (a problem, a benefit, a social proof point, an offer) teach the algorithm more than cosmetic tweaks to one idea.
- Refresh constantly. Rotate in new concepts before performance decays, so the campaign never runs dry.
Executing that at the required pace is where an app ad maker earns its place. Instead of waiting on a designer for every size and angle, you describe the app once and get a batch of on-brand creative, in every placement size, on flat pricing so testing volume does not cost extra. Pair it with strong ad copy and you can feed Google and Meta the asset breadth they optimize best with.
Frequently asked questions
What is a good cost per install?
It depends entirely on your category and what a user is worth to you. A casual game might target $1 to $2 per install, while a subscription finance app can profitably pay $10 or more because each user's lifetime value is far higher. The right question is not "what is a good CPI" but "what can I pay per install and still make money once those users convert in-app."
How many creatives do I need for an app campaign?
Plan for at least 10 to 20 distinct creative concepts to start, then refresh regularly. Google App campaigns and Meta both optimize best with a deep, varied asset pool, and app audiences fatigue fast, so ongoing volume matters more than any single perfect ad. The constraint is usually production speed, not ideas.
Which platform is best for app install ads?
Most consumer apps start with Meta and Google App campaigns because of their reach and mature optimization, add TikTok when the audience skews younger, and layer in Apple Search Ads to capture high-intent App Store searches. There is no single best platform; the right mix depends on where your users are and which channels hit your target cost per action.
Do I need video for app install ads?
Video helps on Meta, TikTok, and YouTube, but strong static and image creative still drives installs, especially on Google Display and in feed placements. You do not need to start with video. Begin with a deep pool of image and copy variations, learn which angles convert, then produce video around the winners.
