## Overview
In accordance with IAB/MRC Retail Media Measurement Guidelines, Topsort provides comprehensive transparency in all reporting to ensure advertisers have full visibility into campaign performance and measurement methodologies.
## Required Disclosures
### Attribution Methodology
All reports must clearly disclose:
1. **Attribution Model Used**
* Last-click, last-impression, or multi-touch
* Model-specific rules and priorities
* Any customization applied by marketplace
2. **Attribution Windows**
* Click-through window duration (e.g., 7, 14, 30 days)
* View-through window duration if applicable
* Window start and end timestamps
3. **Viewability Standards Applied**
* Display: 50% pixels, 1+ second
* Video: 50% pixels, 2+ seconds
* Large format: 30% pixels, 1+ second
### Data Quality Indicators
Reports include data quality metrics and methodologies used for measurement validation.
Each report provides:
* Total impressions delivered
* Viewability validation methodology
* Data collection approach
* Quality assurance measures applied
### Measurement Limitations
All reports must include disclaimers about:
* Cross-device tracking limitations
* Identity resolution methodology
* Cookie/identifier persistence
* Data collection gaps
## Report Components
### Standard Metrics Section
Every campaign report includes:
```
CAMPAIGN PERFORMANCE SUMMARY
━━━━━━━━━━━━━━━━━━━━━━━━━━━
Measurement Period: [Start Date] - [End Date]
Attribution Model: [Model Type]
Attribution Window: [X days click] / [Y days view]
Viewability Standard: IAB/MRC Compliant
Data Quality: Validated per methodology
```
### Detailed Transparency Notes
Reports contain expandable sections for:
1. **Methodology Documentation**
* How impressions are counted
* Viewability measurement approach
* Conversion tracking methods
* De-duplication rules
2. **Data Sources**
* First-party vs third-party data
* Deterministic vs probabilistic matching
* Panel data extrapolation (if used)
* Modeling assumptions
3. **Incrementality Indicators**
* Whether incrementality testing was performed
* Test methodology (RCT, synthetic control, etc.)
* Confidence intervals if available
* Baseline vs incremental conversions
