Meta will usually hand you a cheaper install in India. Google will usually hand you a better user. If you've been picking between Google App Campaigns vs Meta on CPI alone — CPI being cost per install, what you pay for one app download — you've been optimising for the wrong number. It's why your install graph looks great while your retention and revenue don't move.
This is the honest comparison, built from how Indian app accounts actually behave in 2026: where each platform's cost per install lands, which one keeps users coming back and spending money, how Apple's privacy rules change the maths on iPhones, and the budget split we run when we're growing an app on both platforms at once.
The platform that gives you the cheapest install and the platform that gives you the cheapest paying user are frequently not the same platform. Decide which one you're actually buying before you compare costs.
Google App Campaigns vs Meta — the CPI reality
India is one of the cheapest places on earth to get someone to download your app. The average Android install costs around $0.15–$0.40 — roughly ₹13 to ₹35 — a fraction of what the same install costs in the US or UK. Within that, the two giants behave differently. (Google App Campaigns is Google's automated app-ads product; Meta runs your app ads across Facebook and Instagram.)
| Factor | Meta App Installs | Google App Campaigns |
|---|---|---|
| Raw CPI (India) | Lowest — the cheap-install leader | Typically 15–40% higher for same geo |
| Install intent | Interrupt-driven (Feed, Reels, Stories) | Higher intent (Search, Play Store) |
| Retention / ROAS | Wider quality spread | Often stronger per install |
| Surfaces | Facebook, Instagram, Reels, Audience Network | Search, Play, YouTube, Discover, Gmail |
| Creative control | High — you choose format & placement | Asset-based — Google assembles & serves |
| Best at | Scale & top-of-funnel discovery | High-intent, mid-funnel conversion |
Read that retention row twice. ("Retention" just means how many people keep using your app instead of deleting it; "ROAS" is return on ad spend — the revenue you earn for every rupee you put in.) A Google install can cost 30% more and still work out cheaper per paying user who sticks around, because so much of Google's traffic comes from people actively searching or browsing the Play Store — they already want what you're offering. Meta's strength is the opposite: unmatched scale, the most reliable way to reach a huge audience cheaply. But you're catching people mid-scroll who weren't looking for you, so the quality of those users varies more, and the work you do after the install matters more.
Stop comparing installs. Compare what people do in the app
This is the single most important shift in the whole debate. You can tell each platform to chase one of two goals: the cheapest installs, or the cheapest "in-app events" — actions that prove a user is valuable, like a signup, a first purchase, or a subscription. Once your app produces 50+ of these events a week, telling the platform to chase the event instead of the install consistently wins on both Google and Meta. Yes, your cost per install goes up. But your cost per good user goes down — and that trade is almost always worth taking.
When you optimise for installs alone, you're telling the platform's algorithm: "find me the people most likely to tap install, and nothing more." It obliges — with cheap installers who never open the app twice. The whole Google-vs-Meta question only makes sense once both are aimed at a real action that makes you money.
Optimise for the install and you'll get installers. Optimise for the event and you'll get a business.
The iOS complication
On Android phones, both platforms can see enough about what users do to make smart decisions. iPhones are a different world. To protect privacy, Apple no longer lets ad platforms track individual users; instead everything routes through a limited reporting system called SKAdNetwork. The 2026 version (SKAdNetwork 5) reports a bit more than before, but the data still arrives late and is partly an estimate rather than an exact count. You simply don't get to see what each individual user did.
In plain terms: iPhone campaigns need an MMP — a mobile measurement partner, a third-party tool that stitches together the patchy data into a usable picture — and a tolerance for fuzzier numbers. Meta and Google both blend Apple's limited reports with their own estimates, so judge iPhone budgets on how a whole group of users performs over time, not on the exact per-install numbers you can still get on Android. For iPhone users who are actively searching, putting 10–20% of budget into Apple Search Ads — Apple's own ads at the top of App Store search results — often buys your most valuable users.
The GUROB budget split — use both, weighted
For most apps with enough budget to feed two channels, the answer to "Google or Meta" is "both, in the right ratio." A sensible starting allocation:
- 40–60% Meta — reach & discovery. This is your volume engine: it puts your app in front of the most people for the least money. Run it broad, feed it strong video, and aim it at your in-app event. Most of your raw installs come from here.
- 30–50% Google App Campaigns — high-intent conversion. This captures people already searching, browsing the Play Store, or watching relevant YouTube videos. Google decides where your ads show, so you can't pick the spots — you can only supply great assets (text, images, video). Variety and quality of those assets is your one lever.
- 10–20% Apple Search Ads — high-intent iPhone users. The most direct line to people typing your kind of app into the App Store. A small slice, but unusually valuable users.
Then rebalance every two to four weeks — but judge it on cost per in-app event and how many users are still active on Day 7, not on which platform reported more installs. The mix should shift toward whichever platform is delivering paying users who stick around most cheaply this month — not whichever shows the prettier cost per install.
When you should run only one
Splitting budget across two platforms only works if each one gets enough spend to learn what works. Both Google and Meta run a "learning phase" — the first stretch of a campaign where the system is still figuring out who to show your ads to, and results are erratic until it gathers enough data. Below roughly ₹1.5–2 lakh/month, two half-fed campaigns never get past that phase and both underperform a single, properly fed campaign. If you're under that budget, prove one channel first: Meta if you need reach and have strong video, Google if people actually search for your kind of app. Get to a steady cost per event, then add the second platform with confidence.
This is the core of how we approach app marketing — channel choice driven by unit economics, not platform loyalty. And because we run on performance, the only number that pays us is the one that pays you.
Common mistakes in the Google vs Meta decision
- Picking on cost per install alone. The cheapest install is worthless if that person never comes back or pays. Always compare cost per paying, returning user.
- Telling both platforms to chase installs. Once you have 50+ valuable in-app actions a week, switch to chasing that action instead. Install-chasing is a beginner setting you should outgrow fast.
- Starving both platforms. Two campaigns on half-budget each is the most common reason new app accounts stall. Concentrate, learn, then expand.
- Using the same ads on both. Meta rewards native vertical video (think Reels); Google needs a broad library of text, images, and clips to mix and match across its different placements. Feed each what it actually uses.
Frequently asked questions
In closing
The Google App Campaigns vs Meta question doesn't have a universal winner — it has a right answer for your app, how you make money, and what stage you're at. Meta buys you reach and cheap installs; Google buys you people who already want what you offer, and who stick around; Apple Search Ads buys you your best iPhone users. The skill is weighting them by cost per valuable user and rebalancing as the data comes in.
