Note: TikTok Shop AOVs are significantly lower than DTC site AOVs due to impulse purchase behaviour and lower price points. Your DTC AOV will apply for Instagram affiliates driving to the website. TikTok Shop AOV typically sits at £15-25 for supplements. The orders-per-affiliate metric (avg 16/mo across top 3) is the most transferable benchmark for planning.
