When Should Your App Start Paying for Installs?

What is paid user acquisition?

Paid user acquisition is buying app installs or in-app actions through ad networks such as Meta, Google and Apple Search Ads, as opposed to growing through store search, referrals and word of mouth.

The question is not whether to use paid, but when. Spend too early and you pay to learn things your first users would have told you for free. Spend too late and competitors buy the audience first.

How organic share changes with scale

Median organic share by app size, from the global dataset in Linkrunner's published research:

Three patterns stand out:

• The biggest drop comes between 10k and 50k installs. Organic share falls by about 20 percentage points, which is where paid becomes a core channel rather than an experiment.
• It then plateaus. Between 10k and 500k installs, the typical app gets about a third of its installs from paid.
• The largest apps swing back towards organic. At 500k installs and above, brand recognition and store ranking start doing more of the work.

The Indian startup data follows a similar shape at a lower level: about 56% organic under 50k installs, rising to about 75% to 80% for the largest apps. See organic vs paid installs for both datasets.

When should an app start paid acquisition?

Most apps should start testing paid acquisition between 1k and 10k installs, once they know who their retained users are and have attribution in place. That is the band where the median app's organic share begins to fall.

The signals that you are ready:

• You have a clear activation event, such as signup, first transaction or first lesson, and you track it.
• Your install to signup rate is stable. The median Indian app converts about 20% of installs to signups; see the install to signup benchmarks.
• You know your rough unit economics, even if only as a range, so you can tell whether a ₹20 install pays back.
• Organic growth has flattened, rather than still compounding month on month.

What this means for timing

1. Before 1k installs: focus on product and word of mouth. Paid spend rarely pays back before you know who your users are. Small, deliberate tests are fine; scaling is not.
2. 1k to 10k installs: the inflection point. This is when most apps start paid campaigns, so it is also when attribution needs to be in place.
3. 10k to 500k installs: paid drives a third or more of growth. Every misattributed install now has a real budget cost.
4. 500k+: brand and organic catch up again, and the job shifts to protecting efficiency and cutting campaigns that only claim organic users.

What should a first paid budget look like?

Start with a test budget large enough to judge cost per signup, not just cost per install. The aim of the first month is to learn which audience and creative convert, not to grow.

• Pick one or two networks, usually Meta and Google, rather than spreading thin.
• Benchmark against your category. The median Indian app pays about ₹20 per paid install and about ₹48 per signup; category ranges are on the CPI benchmarks page.
• Optimise for signups, not installs, once you have enough volume for the network to learn.
• Hold back some budget for creative refreshes, since performance tends to decay as the same ads run for weeks.

Mistakes that waste early budgets

• Spending before measurement is live. You cannot recover attribution data for installs that were never tracked.
• Trusting network dashboards alone. Each network claims every install it touched, so totals overlap.
• Judging on CPI alone. Cheap installs that never sign up are the most expensive installs you buy.
• Ignoring organic cannibalisation. Some paid installs would have arrived organically anyway. Watch whether organic falls when paid rises.

Set up measurement before you spend

The cheapest time to set up attribution is before paid campaigns begin, not after you have spent and cannot tell what worked. Any MMP, such as Linkrunner, Tenjin or Kochava, should give you deduplicated installs, campaign-level cost and signup tracking from day one.

Linkrunner's free plan is sized to get early-stage apps through the inflection point and show which channels actually work.

FAQ

How many installs should an app have before running paid ads? The benchmarks suggest most apps start paid acquisition between 1k and 10k installs. Below 1k, apps are about 93% organic at the median, and paid spend rarely pays back before product fit is clear.

What share of installs should come from paid? For apps between 10k and 500k installs, the median is about a third paid and two thirds organic. Very small apps get almost everything organically, and the largest apps drift back towards organic as their brand grows.

Should I set up attribution before or after starting paid campaigns? Before. Attribution only works on installs it sees, so anything you spend before tracking is live cannot be matched to a campaign later.

Is it bad if my app is mostly paid? Not necessarily. About a fifth of Indian app startups are paid-led, and in the global data, categories such as e-commerce and travel lean on paid by design. It becomes a problem only when cost per signup is above what a user is worth to you.

What metric should I judge my first paid campaigns on? Cost per signup or cost per first key action, not cost per install. Read it next to your category benchmarks so you know whether a result is normal for apps like yours.
