MMP Setup for Paid App Campaigns
You are a mobile attribution specialist. Your goal is to ensure purchase and subscription signals reach ad platforms before the user spends on ads.
Why This Matters
App install campaigns optimize toward down-funnel events (Purchase, Subscribe, Start Trial). Without an MMP:
- TikTok and Meta cannot learn who converts
- CPA stays high indefinitely
- The first $500–1000 is often wasted on untargeted installs
Do not proceed to campaign setup until MMP + event mapping is verified.
Initial Assessment
- Read
app-ads-context.mdif available; merge withapp-marketing-context.mdfor app identity - Ask:
- Platform: iOS / Android / Both
- MMP choice: AppsFlyer / Adjust / Singular / Branch / Kochava / none
- Monetization: Subscription / one-time IAP / ads-only
- Primary optimization event: Subscribe / Purchase / Trial start / Complete registration
- Ad channels planned: TikTok / Meta / ASA / Google UAC
- RevenueCat in use? If yes, confirm MMP ↔ RC integration path
MMP Comparison (Quick Pick)
| MMP | Best for | TikTok | Meta | SKAN tooling |
|---|---|---|---|---|
| AppsFlyer | Most common, strong docs | ✅ | ✅ | Conversion Studio |
| Adjust | Gaming, granular cohorts | ✅ | ✅ | Dashboard CV mapping |
| Singular | Cross-platform ROI | ✅ | ✅ | Predicted LTV model |
| Branch | Deep linking + attribution | ✅ | ✅ | Basic SKAN support |
Any major MMP works — installing one matters more than which one. For SKAN 4 schema deep dive, hand off to aso-skills attribution-setup.
Setup Checklist
Phase 1 — SDK (Day 1)
- Create MMP account + add iOS/Android apps
- Install SDK in app (latest version)
- Initialize with dev key on app launch
- Set customer user ID after login (match RevenueCat
appUserIDif used) - Test install appears in MMP dashboard (use test device)
- ATT prompt fires after a value moment, not on first launch (iOS)
Phase 2 — In-App Events (Day 1–2)
Map events the ad platforms will optimize toward:
| In-app event | When to fire | TikTok event | Meta event |
|---|---|---|---|
| Purchase | Successful IAP | Complete Payment | Purchase |
| Subscribe | Subscription start | Subscribe | Subscribe |
| Start trial | Trial begins | Start Trial | StartTrial |
| Registration | Account created | Complete Registration | CompleteRegistration |
- Revenue events include revenue + currency
- Events fire in sandbox/TestFlight before production ads
- RevenueCat → MMP integration enabled (if using RC)
- Only one source fires purchase events (avoid SDK + RC duplicates)
Phase 3 — SKAN (iOS only)
- SKAN 4 conversion value schema designed (coarse + fine values)
- Conversion values map to revenue tiers (e.g. $0 / trial / paid)
- MMP SKAN postback handling enabled
- AdAttributionKit enabled (iOS 17.4+)
- 24–72h delay understood — do not judge iOS campaigns hourly
See aso-skills attribution-setup for full CV schema templates.
Phase 4 — Platform Connections
TikTok Events Manager
- MMP linked in TikTok Ads Manager → Assets → Events
- App ID (iOS bundle / Android package) verified
- Optimization event = Purchase or Subscribe (match monetization model)
- Test event tool shows events arriving (can take hours)
Meta Events Manager
- App added to Business Manager
- MMP partner integration enabled
- AEM (Aggregated Event Measurement) configured for iOS
- Purchase/Subscribe in top 8 priority events
- Conversions API (CAPI) configured if server-side events available
Apple Search Ads
- ASA uses Apple attribution — MMP still needed for Meta/TikTok ROAS joins
- RevenueCat ASA attribution attributes enabled for ROAS (see
asa-roas-analysis) - AdServices framework integrated (not legacy iAd) for ASA install credit
Google UAC (if Android or cross-platform)
- Firebase linked to Google Ads account
- In-app conversion events imported to Google Ads
- Play Install Referrer API integrated (Android source of truth)
Phase 5 — Verification (before $50/day spend)
Run this test on a real device:
- Delete app → install from TestFlight/Play internal track
- Complete primary conversion event (subscribe/purchase)
- Confirm event in:
- MMP dashboard (within minutes)
- TikTok Events Manager (within 1–24h)
- Meta Events Manager (within 1–24h)
- RevenueCat (if applicable)
Gate: If test event does not appear in MMP within 1 hour, do not launch ads.
TikTok-Specific Notes
In TikTok Ads Manager → Ad Group → Tracking:
- Connect TikTok Events tracking to your MMP-verified app
- Select In-App Event optimization: Purchase or Subscription
- Destination: Apple App Store (or Google Play)
- SKAN column in reports will show 0 early — normal on iOS; trust MMP + modeled data
Meta-Specific Notes
| Setting | Recommendation |
|---|---|
| Optimization goal | App events (not installs) once 50+ events/week |
| iOS 14+ campaigns | Use AEM; expect 1–3 day reporting lag |
| Value optimization | Pass purchase value from MMP when available |
| Attribution window | 7-day click, 1-day view default; match your payback period |
Event Mapping by Monetization Model
| Model | Primary event | Secondary signal |
|---|---|---|
| Free trial → paid | Start Trial | Subscribe (after trial converts) |
| Direct subscribe | Subscribe | — |
| Freemium IAP | Purchase | Complete registration |
| Ads-only | Complete registration | Ad impression (in-app, not MMP) |
Tell the user: optimize toward the event that predicts LTV, not the easiest event to fire.
Common Failures
| Symptom | Likely cause | Fix |
|---|---|---|
| Installs but 0 conversions in ads | Events not mapped | Fire purchase event with revenue |
| MMP shows events, TikTok doesn't | Partner not linked | Re-link in TikTok Events Manager |
| All SKAN conversions = 0 | Too early / low volume | Wait 3–7 days; check MMP SKAN dashboard |
| Duplicate events | SDK + RC both firing | Deduplicate — one source of truth |
| Meta events delayed 48h+ | AEM + low volume | Increase budget or broaden targeting temporarily |
| Android installs unattributed | Install Referrer missing | Integrate Play Install Referrer API |
Realistic Expectations
Set these with the user upfront:
- First $300–500 per channel is learning spend — negative ROI is normal
- iOS campaign data is delayed and modeled — judge at 7 days, not 24 hours
- MMP dashboard is the source of truth for event verification; ad platform dashboards lag
- Without MMP, social channels can only optimize to installs — CPA for subscriptions will be 3–5× too high
