Answer in brief
Seven attribution mistakes come up again and again on a first campaign: launching before the SDK is live, using plain store links, skipping the test install, tracking too many events, never checking the attribution window, judging campaigns by installs alone, and trusting the ad platform's numbers over the MMP's without knowing why they differ. Each one shows a recognisable symptom in the first report, and most are prevented by a checklist before launch.
Find your symptom first
Most first-campaign problems show up as one of a few patterns in the report. Start from what you see.
| What you see | Likely mistake |
|---|---|
| Spend on a channel, zero installs under it | 1 or 2 |
| Organic installs jump on launch day | 2 or 3 |
| Revenue column empty or far too high | 3 or 4 |
| The bill is higher than planned | 4 |
| MMP and ad platform disagree and nobody knows why | 5 or 7 |
| The "best" campaign brings no paying users | 6 |
Setup mistakes
1. Launching before the SDK is in the live app
The campaign starts on Monday and the app version with the SDK is approved on Thursday. Three days of installs have no source. Fix: start the campaign only after the release with the SDK is live in the store.
2. Putting a plain store link in an ad or post
A direct App Store or Google Play URL records nothing. This happens most with influencers and email, where someone copies the store link out of habit. Fix: give every partner a tracking link and tell them it is the only one to use. See how a tracking link works.
3. Skipping the test install
Everything looks connected in the dashboard, and the first real install proves it was not. Fix: before launch, click, install and trigger your main event on a real phone for each channel. The steps are in testing attribution before you spend.
4. Tracking every event the app has
A long event list is hard to test, and a purchase event that fires twice doubles the revenue reported for it. On plans billed by event it also raises the cost. Fix: start with the short list in which events to track first.
Settings mistakes
5. Never opening the attribution window setting
The window decides how long after a click an install still counts. Teams often leave the default, then cannot explain why the MMP and the ad platform report different totals. Fix: read your lookback window for each channel, write it down, and compare it with the window the ad platform shows in its own settings.
Reading mistakes
6. Judging campaigns by installs or cost per install
A low cost per install says nothing about whether those users pay. A campaign can lead on installs and trail on revenue. Fix: rank campaigns by a revenue event, and use cost per install only to spot delivery problems.
7. Picking one dashboard and ignoring the other
Some teams trust the ad platform because its number is bigger. Others trust the MMP and assume the platform is wrong. The two count by different rules, and the gap has causes you can list. Large platforms also have their own way of reporting conversions to the MMP, as described in self-attributing networks. Fix: use the MMP to compare channels with each other, use the platform's dashboard to manage delivery inside that platform, and note the usual gap so you notice when it changes.
What to do next
Mistakes 1 to 5 are prevented before launch. Go through the pre-launch checklist with your developer and tick each item. Mistakes 6 and 7 are habits, so agree on them as a team: one main event, one place to compare channels, and one written record of your settings.
Questions and answers
What is the most expensive attribution mistake?
Launching before measurement works. Every install from that period has no source, so the spend cannot be evaluated and the data cannot be recovered later.
How do I know if my attribution setup is broken?
Look for a paid channel with spend and no installs, an organic row that jumps when ads start, or an event column that is empty. Each of those points to a specific setup error.
