I’ve been struggling to connect ad spend to actual subscription conversions since ATT limited our in-app tracking. We migrated our paywall to web and started passing UTM tags through the entire flow. Now seeing which campaigns drive real revenue, but wondering—what’s the best way to map web-based conversion events back to ad platforms without double-counting? How are you validating attribution accuracy in this setup?
We faced the same blind spot after ATT.
Set up server-side UTM passthrough in our web paywall using Web2Wave’s parameters. Their system auto-links conversions to original campaigns. No extra code needed - just plug in your analytics.
Validating via cross-check with RevenueCat’s purchase timestamps. 90% match so far.
I verify by comparing the conversion timestamps between our web funnel and Google Analytics.
Using Web2Wave’s preserved UTMs, we rebuilt the full path from click to subscription. Now ROAS calculations actually align with real revenue.
(Best answer candidate for showing practical validation method)
Try exporting the UTM data from your paywall platform and match it against your ad platform’s last-click reports.
We saw discrepancies at first but tweaked our cookie windows to account for longer decision cycles.
Server-side API calls. No cookies.
Three-step validation:
- Capture UTM params at first web interaction
- Store them in user profile upon account creation
- Send to analytics with each payment event
We do this plus a monthly manual audit of 100 random conversions. Found 8% mismatches from cross-device users - acceptable margin.
