Episode notes
GMV Max Is A Blended Optimization System
- GMV Max is not an ad format but a blended optimization system that mixes paid, organic, and creator sales.
- It optimizes across TikTok Shop assets to maximize gross merchandise value for chosen SKUs.
All SKU Orders In One-Day Window Get Credited
- GMV Max attributes all orders for promoted SKUs during a one-day product-level window, even without ad exposure.
- That makes the reported ROI a channel-level blended metric, not a pure paid-ad ROAS.
ROI Number Often Appears Juiced
- The GMV Max ROI line combines paid, organic, affiliate, and search GMV, then divides by ad spend, inflating apparent efficiency.
- Comparing that ROI to historical ROAS without adjustment will mislead scaling decisions.
