description	Use when setting attribution model for conversion tracking. Window = how long after a touchpoint we credit conversion.

Attribution Window Strategy

Attribution window: 7-30 days for most B2C, 30-90 for B2B. Multi-touch attribution > last-click for accurate channel ROI.

Attribution model choices

1. Last-click — 100% credit to final touch (simplest)
2. First-click — 100% credit to first touch
3. Linear — equal credit across all touches
4. Time-decay — recent touches weighted higher
5. Position-based — first + last weighted higher
6. Data-driven — algorithm assigns credit (Google Ads default)

Most businesses: data-driven if available, time-decay otherwise.

Window length by industry

Industry	Recommended window
E-commerce (low AOV)	7-14 days
Consumer SaaS	14-30 days
Enterprise SaaS	30-90 days
Real estate	30-90 days
Trading cards (CardPrepAI)	14-30 days
Big-ticket items	60-90 days

Implementation

1. Set window in GA4 (Admin > Attribution settings)
2. Match window in advertising platforms (Google Ads, Meta)
3. Document for team
4. Don't change frequently (loses comparability)
5. Use position-based or data-driven for accuracy
