Chapter 1: Understanding Platform Models—TikTok Shop vs. YouTube Shopping Affiliate
TikTok Shop Smart Promotion: Key Features & Fees
TikTok Shop's Smart Promotion, mandatory since April 2026 for major U.S. campaigns, charges sellers a platform fee based on Gross Merchandise Value (GMV):
- Regular periods: 3.5% of total store GMV
- Campaign periods (e.g., Flash Sales, Premium Offers, including "mega campaigns"): 4.5% (3.5% base + 1% campaign fee; this is the maximum documented Smart Promotion fee according to October 2026 official evidence)
- Exclusions: You can exclude specific products from Smart Promotion; excluded products are not fee-liable
- No budget caps: Unlike the legacy co-funded mode, sellers cannot set hard monthly spend limits (US Smart Promotion Introduction / FAQ).
TikTok matches your fee with an equal discount incentive on the platform (e.g., a 3.5% fee = 3.5% customer discount) and adds bonus cashback offers.
YouTube Shopping Affiliate: Core Mechanics
YouTube's affiliate program, now open to all YouTube Partner Program members with 500+ subscribers, features:
- Variable commissions: Set by the merchant for each product/category. Estimated rates shown as you tag; payout reflects the actual rate at purchase.
