Cross-Promotion Strategies for Mobile Apps

Cross-promotion is the practice of using one app's audience to drive installs for another app. It works between your own apps (if you have a portfolio) or between partner apps that share an audience. Done well, cross-promotion delivers high-quality users at near-zero marginal cost.

For deep linking fundamentals, see the deep linking concepts guide. For influencer partnerships, see influencer marketing for mobile apps.

Cross-Promotion Models

Own Portfolio Cross-Promotion

If you publish multiple apps, your existing user base is your best acquisition channel for new titles:

Format	Description	Example
In-app banners	Show a banner promoting your other app	A weather app shows a banner for your travel app
Interstitials	Full-screen promotion at natural transition points	Between game levels, show your new game
Settings/about page	Link to your other apps	"More from [Studio Name]" section
Post-action prompt	After the user completes a task, suggest a related app	After completing a workout, promote your nutrition app
Cross-app rewards	Give users benefits in App A for installing App B	"Install [App B] and get 500 bonus coins in [App A]"

Key principle: Promote at moments when the user has just experienced value, not when they are frustrated or mid-task.

Partner Cross-Promotion

Exchange visibility with apps that share your target audience but are not direct competitors:

Your App	Partner App	Shared Audience
Running tracker	Nutrition planner	Health-conscious users
Budget planner	Investment tracker	Financially engaged users
Language learning	Travel guide	Travel enthusiasts
Recipe app	Grocery delivery	Home cooks
Meditation	Sleep tracker	Wellness-focused users

Partner arrangements can be:

• Equal exchange: Each app shows the other's promotion. No money changes hands.
• Revenue share: If one app has a larger audience, the smaller app pays a CPI or revenue share.
• Network: Multiple apps in a cross-promotion network, rotating promotions.

Cross-Promotion Networks

Several networks facilitate cross-promotion between unrelated apps:

• Chartboost: Gaming-focused cross-promotion and ad exchange.
• AdColony: Video-based cross-promotion.
• Custom exchanges: Direct deals between app developers.

Networks handle the matching and serving, but you lose control over which apps promote yours. Direct partnerships give more control over brand alignment.

Implementation

In-App Banner Cross-Promotion

The simplest format. Show a banner within your app that links to the promoted app:

┌─────────────────────────────────┐
│  [App Icon] Try BudgetBee!      │
│  Track expenses in 30 seconds.  │
│  [Install]              [×]     │
└─────────────────────────────────┘

Best practices:

• Use a dismiss button (forced promotions annoy users).
• Show the banner after the user has completed a positive action.
• Limit frequency: once per session or once per day.
• Track impressions, taps, and installs to measure effectiveness.

Deep Links in Cross-Promotion

Every cross-promotion link should be a deep link that takes the user to a specific screen, not just the app store:

https://yourpartner.com/promo/running-plans?ref=budgetbee

When the user taps:

1. If the partner app is installed, it opens to the promoted content.
2. If not installed, the user sees a preview and is redirected to the app store. After installation, the app opens to the promoted content via deferred deep linking.

Without deep links, the user installs the partner app and lands on a generic home screen with no context about why they installed.

Smart Banners on Websites

Tolinku smart banner configuration for cross-promotion across web properties.

If you have a web presence, use smart banners to cross-promote your apps based on the page context:

• Blog post about recipes → Show a banner for your recipe app.
• Blog post about budgeting → Show a banner for your finance app.
• Documentation page → Show a banner for the relevant app.

Smart banners detect the user's platform (iOS/Android) and link to the correct app store.

Timing and Targeting

When to Show Cross-Promotions

Timing	Effectiveness	User Experience
After completing a task	High (user is satisfied)	Good
During loading screens	Medium (captive audience)	Neutral
In settings/about page	Low (few users visit)	Good
Before core features	Low (user is annoyed)	Poor
Between content (feeds)	Medium (native-feeling)	Neutral

The best timing is after a positive moment: completing a workout, saving money, finishing a level. The user is in a good mood and more receptive.

Audience Targeting

Not every user is a good candidate for cross-promotion. Target users who:

• Are active and retained (they are engaged enough to try another app).
• Have interests that align with the promoted app (use in-app behavior signals).
• Have not already installed the promoted app (check with platform APIs or your own backend).

Avoid cross-promoting to:

• New users who have not yet found value in the current app.
• Users in the middle of a paid flow or conversion funnel.
• Users who have previously dismissed the promotion multiple times.

Measuring Cross-Promotion

Metrics to Track

Metric	Formula	Good Benchmark
Impression rate	Impressions / DAU	20-40% (not all users should see promos)
Tap-through rate	Taps / Impressions	2-5%
Install rate	Installs / Taps	20-40% (since users are already in an app context)
Cost per install	Value of lost engagement / Installs	Should be lower than paid CPI
Cannibalization rate	Decline in source app engagement after cross-promo	Under 5%

Cannibalization Risk

The main risk of cross-promotion: users leave your app and never come back. Monitor:

• Session length: Does it drop after cross-promotion exposure?
• Retention: Do users who see cross-promotions retain at the same rate?
• Revenue: Does ARPU change for users exposed to cross-promotions?

If cross-promotion is cannibalizing your source app, reduce frequency, improve targeting, or switch to less intrusive formats (settings page instead of interstitials).

Attribution

Track the full funnel from impression in App A to install and engagement in App B:

1. Impression: User sees the cross-promotion in App A.
2. Click: User taps the promotion.
3. Redirect: User lands on the app store or, if App B is installed, opens App B.
4. Install: User installs App B (if new).
5. Activation: User completes onboarding in App B.
6. Retention: User remains active in App B after 7 and 30 days.

Use unique tracking parameters in your deep links (e.g., ?ref=appA&campaign=cross-promo-jan) to attribute each step.

Common Mistakes

Mistake	Impact	Fix
Promoting to brand-new users	Disrupts onboarding, increases churn in source app	Only cross-promote to retained users (day 7+)
No frequency cap	Users feel spammed	Limit to once per day or once per session
Generic app store link (no deep link)	User installs but has no context, low activation	Use deep links with deferred deep linking
Promoting irrelevant apps	Low conversion, user annoyance	Partner with apps that share your audience
Not measuring cannibalization	Source app engagement drops unnoticed	Track source app metrics for cross-promo-exposed users
Full-screen interstitials during core flows	Rage-inducing UX, negative reviews	Only show promotions at natural break points

Tolinku for Cross-Promotion
