Definition

## What is organic install share?

**Organic install share is the percentage of an app's installs that no paid campaign or tracked link is credited with.**

**Organic install:** an install that no tracked campaign or link is credited with.

**Cannibalisation:** when paid campaigns take credit for users who would have installed organically anyway.

Formula

## How to calculate Organic share

`Organic share = Organic installs ÷ Total installs × 100`

**Organic installs**

installs with no attributed paid or tracked source

**Total installs**

organic plus attributed installs in the same period

### Where definitions differ

| Variant | Formula | When to use it |
|---|---|---|
| MMP organic share | Unattributed installs ÷ All installs × 100 | Organic means 'not credited to any tracked source', so untracked paid traffic lands here. |
| Store-reported organic | Store search and browse installs ÷ All store installs × 100 | From the store consoles; their source categories are not the same as an [MMP](https://linkrunner.io/glossary/what-is-a-mobile-measurement-partner?utm_source=appmetricslibrary&utm_medium=referral&utm_campaign=metric-organic-install-share&utm_content=inline)'s. |

**By channel:** Separating organic from paid installs depends on every paid source being connected to one attribution tool; MMPs such as [Linkrunner](https://www.linkrunner.io/?utm_source=appmetricslibrary&utm_medium=referral&utm_campaign=metric-organic-install-share&utm_content=inline), AppsFlyer and Adjust report installs they cannot credit to a source as organic.

Answer

## Is a high organic share good?

It is good for cost, but it can also mean your tracking misses paid sources, which then show up as organic. Before celebrating a rising organic share, check that every paid channel and link is tagged.

By vertical

## How Organic share differs by vertical

| [EdTech](https://appmetricslibrary.com/verticals/edtech/) | Exam seasons and word of mouth push organic share up at the same time as paid spend. |
|---|---|
| [Fintech](https://appmetricslibrary.com/verticals/fintech/) | Referral programmes are tracked, so they move installs out of organic. |
| [OTT and streaming](https://appmetricslibrary.com/verticals/ott/) | Big title launches lift organic installs; separate launch weeks in reports. |
| [Gaming](https://appmetricslibrary.com/verticals/gaming/) | Featuring and chart position drive organic spikes after paid bursts. |

Pitfalls

## Common mistakes

- Treating organic as free growth without checking for untagged paid traffic.
- Cutting paid spend because organic share is high, then finding organic falls too.

FAQ

## Questions

**How do you calculate organic install share?**

Divide organic installs by total installs and multiply by 100. 6k organic installs out of 10k total is a 60% organic share.

**Why did my organic installs drop when I paused ads?**

Paid campaigns lift store ranking and brand searches, so some organic installs depend on paid activity. A drop after pausing is a sign of that halo, not necessarily of misattribution.

**Can paid installs show up as organic?**

Yes. Untagged links, broken postbacks or networks that are not connected to your MMP all leave paid installs unattributed, and unattributed installs are reported as organic.

**Are the calculator's example inputs benchmarks?**

No. The example inputs only make the calculator show a worked answer when the page loads; they are not typical, good or target values. Replace them with your own numbers.

**Does the calculator send my numbers anywhere?**

No. It runs entirely in your browser, and nothing you type is stored or sent anywhere.

**Why do tools report different values for the same metric?**

Because definitions differ: what counts as active, which attribution window applies, whether organic users are included and how days are cut by timezone. Align the definition before comparing numbers.
