Investigation Workflow
Universal Pixel Issues
- Check pixel status using Chrome Developer Tools Network tab
- Verify Universal Pixel ID matches advertiser configuration
- Review event tracking implementation and parameter formatting
- Test pixel fires on all required pages (homepage, conversion, etc.)
- Check for browser ad blockers or privacy extensions blocking tags
- Verify consent management platform isn't blocking pixel loads
- Use TTD Pixel Helper Chrome extension for real-time validation
Attribution Discrepancies
- Compare attribution models between TTD and GA4/other platforms
- Review lookback windows (TTD default: 30-day click, 7-day view)
- Check for timezone mismatches in reporting dashboards
- Verify conversion counting methodology (unique vs. total conversions)
- Examine cross-device attribution settings and methodology
- Review last-touch vs. multi-touch attribution differences
- Check for conversion de-duplication settings
UID2 Integration Issues
- Verify email normalization (lowercase, trim whitespace)
- Check SHA-256 hashing implementation on client or server
- Review UID2 token generation API responses for errors
- Confirm UID2 tokens are being passed to Universal Pixel correctly
- Check opt-out transparency portal for user opt-outs
- Verify refresh token logic for maintaining persistent IDs
- Review match rate reports in TTD platform
Campaign Performance Issues
- Check campaign flight dates and daily budget pacing
- Review bid strategy and performance goal settings
- Verify targeting isn't too narrow (audience, geo, inventory)
- Check inventory availability and bid competitiveness in auction insights
- Review brand safety and contextual targeting exclusions
- Confirm creative assets meet specifications and are approved
- Examine frequency caps and audience saturation
