Why TikTok Ads Manager and an MMP May Show Different App Install Counts
Reconcile different TikTok app install counts by checking event mapping, attribution rules, and report timing.
When TikTok Ads Manager and a mobile measurement partner (MMP) disagree on app installs, put the reports side by side before changing the campaign. Different measurement definitions can produce different totals even when both systems are receiving data.
Verify the campaign and install event
Check the app, platform, campaign, and date range. Confirm that the selected event in each report means the same thing and that the integration is sharing the intended event. Verify with a documented test acquisition if a report remains at zero. The test should separate whether the event exists, whether it was shared, and whether it received campaign credit.
Align the comparison
TikTok's discrepancy guide identifies attribution rules, conversion windows, and time settings as reasons the reports can diverge. Record the click-through and view-through settings, reporting time zones, and date basis of both views. Compare a period old enough for normal processing.
If the two sources still differ, share the campaign identifier, event name, date range, time zone, and a redacted test example with the relevant provider. Report each source under its own definition until the cause is confirmed. Avoid forcing a match by switching the event definition mid-comparison.
