AppsFlyer attribution setup and audit brief

AppsFlyer attribution setup and fix across paid and organic channels (MMP specialist) We're a consumer mobile app (iOS and Android) running paid across Google, Meta and Reddit, plus organic channels, using AppsFlyer as our MMP. iOS/SKAN is configured and working (we can see iOS users attributing through Meta). Meta is set up correctly and reporting clean. The problem is the other channels. Specifically: - Google is split across two integrations, and our search traffic is reporting to the wrong one, so we get clicks but no impressions or cost. - Reddit attribution was recently rebuilt and we need it validated end to end. - Organic and self-reported sources (web, social) have inconsistent tagging, so sources appear and disappear between reports and we can't trust the totals. - We want impressions, clicks, cost and installs flowing consistently across all paid channels, the way Meta already does. We know what's broken, so we're after a fixed-price quote against the deliverables below, not an open-ended engagement. If you find something genuinely outside this, flag it before doing the work. Deliverables: 1. Consolidate the Google integrations so all search traffic reports correctly, with impressions and cost flowing 2. Validate Reddit attribution end to end (installs and signup events, both platforms) 3. Clean up and standardise source and campaign tagging across all channels 4. Confirm every paid channel reports impressions, clicks, cost and installs consistently 5. A consistent event and naming convention across all partners 6. Short documentation and a QA checklist so we can catch issues ourselves Stack: AppsFlyer, GA4, Google Ads, Meta Ads, Reddit Ads, plus web and social sources. Please reply with your approach, and rough turnaround. In your reply, briefly tell us how you'd debug a source showing clicks but zero attributed installs.
