Meta usually gives you a cheaper install. Google usually gives you a better user.

If you've been choosing between them on cost per install alone, you've been optimising for the wrong number.

That's why your install graph looks great while retention and revenue sit still.

The honest comparison, from how Indian app accounts actually behave: where each one's cost lands, which keeps users, how Apple changes the maths, and the split we run on both 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 an app downloaded. An Android install runs roughly ₹13 to ₹35 — a fraction of the US or UK.

But the two giants behave very differently inside that range.

Factor Meta App Installs Google App Campaigns
Raw CPI (India)Lowest — the cheap-install leaderTypically 15–40% higher for same geo
Install intentInterrupt-driven (Feed, Reels, Stories)Higher intent (Search, Play Store)
Retention / ROASWider quality spreadOften stronger per install
SurfacesFacebook, Instagram, Reels, Audience NetworkSearch, Play, YouTube, Discover, Gmail
Creative controlHigh — you choose format & placementAsset-based — Google assembles & serves
Best atScale & top-of-funnel discoveryHigh-intent, mid-funnel conversion

Read that retention row twice.

A Google install can cost 30% more and still be cheaper per paying user who sticks around. Why? Because Google's traffic comes from people searching or browsing the Play Store. They already want what you're offering.

Meta's strength is the opposite: unmatched scale, cheaply. But you're catching people mid-scroll who weren't looking for you. So quality varies more, and what you do after the install matters far more.

Stop comparing installs. Compare what people do in the app

This is the most important shift in the whole debate.

You can tell each platform to chase one of two things. The cheapest installs. Or the cheapest in-app events — a signup, a first purchase, a subscription.

Once you produce 50+ events a week, chasing the event beats chasing the install on both platforms.

Your cost per install rises. Your cost per good user falls. Take that trade.

Optimise for installs alone and you're telling the algorithm: "find people likely to tap install, and nothing more."

It obliges. With cheap installers who never open the app twice.

Optimise for the install and you'll get installers. Optimise for the event and you'll get a business.

The iOS complication

On Android, both platforms see enough to make smart decisions. iPhones are a different world.

Apple no longer lets ad platforms track individuals. Everything routes through a limited system called SKAdNetwork.

The 2026 version reports a little more than before. But the data still arrives late and is partly an estimate. You don't get to see what each user did.

So iPhone campaigns need two things. An MMP — a third-party tool that stitches the patchy data into something usable. And tolerance for fuzzier numbers.

Judge iPhone budgets on how a whole group performs over time, not per-install numbers.

And put 10–20% into Apple Search Ads. For people actively searching the App Store, that often buys your most valuable users of all.

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:

  1. 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.
  2. 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.
  3. 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.

Rebalance every two to four weeks. Judge it on two numbers only: cost per in-app event, and how many users are still active on day 7.

Not on which platform reported more installs.

When you should run only one

Splitting only works if each platform gets enough spend to learn.

Both run a learning phase — an opening stretch where results are erratic until enough data arrives.

Below roughly ₹1.5–2 lakh a month, two half-fed campaigns never escape it. Both lose to one properly fed campaign.

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.

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

  1. 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.
  2. 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.
  3. Starving both platforms. Two campaigns on half-budget each is the most common reason new app accounts stall. Concentrate, learn, then expand.
  4. Using the same ads on both. Meta rewards native vertical video. Google needs a wide library of text, images and clips to mix across its placements. Feed each one what it actually uses.

Frequently asked questions

Meta usually delivers a lower raw CPI in India — Android CPIs commonly fall in the $0.15–$0.40 (roughly ₹13–₹35) range, and Google App Campaign CPIs tend to run 15–40% higher for the same geo. But Google's installs often retain and monetise better, so the effective cost per quality user can be comparable. Judge on cost per in-app event, not cost per install.
In most Indian accounts we see, Google App Campaigns produce stronger retention and ROAS per install because much of the volume comes from high-intent surfaces like Search and Play Store. Meta delivers more scale and cheaper installs but a wider quality spread, so post-install event optimisation matters more there. The right answer depends on your app category and monetisation model.
A sensible starting allocation is 40–60% Meta for top-of-funnel scale, 30–50% Google App Campaigns for mid-funnel and high-intent conversion, and 10–20% Apple Search Ads for high-intent iOS installs. Rebalance every few weeks based on cost per in-app event and Day-7 retention, not on install volume alone.
Optimise for in-app events, like a signup or a purchase, once you can produce 50 or more a week. It beats chasing raw installs every time. Your cost per install rises, but the users are far better, so it pays off. Chasing installs alone just trains both platforms to find cheap installers who never come back.
To protect privacy, Apple no longer lets ad platforms track individual iPhone users. Everything routes through a limited reporting system called SKAdNetwork; the 2026 version (SKAdNetwork 5) reports a little more than before, but the data still arrives late and is partly an estimate, not an exact count. So iPhone campaigns need an MMP (a mobile measurement partner — a third-party tool that pieces the patchy data together) and you should judge them on how a whole group of users performs over time, not on exact per-user numbers.
Yes, but differently. Google App Campaigns are asset-driven — you supply text, images, and videos and Google assembles and serves combinations across Search, Play, YouTube, and Discover. You can't pick placements, so the quality and variety of assets is your main lever. Meta gives you more direct control over the creative and placement, which is why Reels-first video matters so much there.
Below a certain budget, splitting starves both platforms of the data they need. Under roughly ₹1.5 to 2 lakh a month, prove one channel first. Meta for scale, or Google for intent. Get to a stable cost per event, then add the second. Two half-fed campaigns lose to one properly fed one.

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.
