Clients ask us this constantly: should we put budget into Apple Search Ads or Google App Campaigns?
The honest answer is usually both - but they do different jobs, attract different intent, and need different creative and CPI/CPA targets. Treating them as interchangeable is how teams burn budget.
In practice, most clients see positive ROAS and ROI from both channels when they're set up properly. The harder question is volume and spend - avoiding overspend on placements or keyword themes where ROAS doesn't hold, and balancing budget across ASA and Google AC to hit target CPAs, ROAS, and LTV rather than maxing one platform in isolation.
When does Apple Search Ads win?
Apple Search Ads (ASA) runs inside the App Store - search results, the search tab, and product pages. Every install comes from someone who was already looking for an app like yours (or yours by name). That's the highest-intent paid signal in mobile.
What we like about it:
- Predictable CPI in most categories ($1–$10 is common; finance and competitive categories run higher).
- Clean attribution through your MMP.
- Simple account structure once you know the pattern: discovery, brand, category, competitor.
Where it falls short: iOS only, volume capped by search demand, and it rewards active management. Set-and-forget ASA accounts drift.
We've used ASA to take apps from invisible to top-10 in category within weeks when the listing converts. Compare the Market's Simples app is a recent example - comprehensive ASO plus disciplined ASA took them from outside the top 200 to #9 in Finance.

When do Google App Campaigns win?
Google App Campaigns (also called Google App Promotion campaigns) spread your budget across Search, Google Play, YouTube, Discover, and Display. You feed it creative assets and a target CPI; Google's algorithm finds installs.
What we like about it:
- Works for iOS and Android.
- Often higher install volume per dollar than ASA in discovery-led categories.
- Strong when you have creative volume - the algorithm needs options.
What trips teams up: less control over placement, noisier attribution on iOS (modelled conversions need reconciling with your MMP), and higher creative production load. Google App Campaigns eat creative. One static image set won't cut it for long.
Our Google App Promotion Campaigns page covers how we structure these for subscriber acquisition and ROAS targets.
Which channel should you start with?
Use this as a starting point - your category, platform mix, and unit economics may shift the answer.
| Situation | Start here |
|---|---|
| iOS-only, people already search your category | Apple Search Ads |
| Android-first or need cross-platform scale | Google App Campaigns |
| Tight unit economics, need predictable CPA/ROAS | Apple Search Ads |
| Need volume beyond what ASA can deliver | Layer Google AC on top |
| Discovery / awareness category | Google AC + short-form video |

How should you stack Apple Search Ads and Google App Campaigns?
- ASA first - fastest path to validated CPI on high-intent iOS traffic.
- Google AC second - separate campaigns for cross-platform Universal App Campaigns (UAC), Play-specific, and YouTube-only where creative-led brands need it.
- Independent CPI/CPA and ROAS targets - ASA and Google AC rarely share the same numbers. Don't force one CPI, CPA, or ROAS target across both.
- One MMP - AppsFlyer, Adjust, or Singular deduping across channels so you're not double-counting.
- Rebalance on economics - shift budget toward keyword themes and placements that hit CPA and LTV; pull back where ROAS doesn't hold, even if CPI looks acceptable on paper.
What's shifted in 2026?
Apple expanded ASA inventory (search tab is real volume now, not just keyword results). Google has cleaner iOS reporting than 18 months ago thanks to deeper SKAdNetwork integration. Both platforms punish single-creative campaigns - if you're not testing variants weekly or fortnightly, you're overpaying for installs.
Where does AI discovery fit in paid acquisition?
Paid search in the stores is only one acquisition path. Increasingly, users ask AI assistants which app to use before they search the App Store at all. If your competitors show up in those answers and you don't, your ASA and AC campaigns are fighting uphill on cold traffic.
Worth checking before you scale spend: run the free AI App Visibility Check to see how ChatGPT, Perplexity, and other assistants talk about your category - and whether your app appears.
