FAQ
Q1. Categories beginners should avoid?
Fashion/beauty (~10% fees + fierce competition) and electronics (high cost ratio + heavy after-service) are hard for beginners. Start with household consumables, baby, or pet goods.
Q2. Average order values by category?
Electronics 200K–1M, fashion 30–100K, beauty 15–50K, food 10–30K, household 10–40K, baby 20–100K, supplements 30–150K. Fixed cost share grows at low price points; target 15K+ KRW AOV.
Q3. Highest-turnover categories?
Diapers/wipes (3 turns/month), supplements (2), pet food (2), household consumables (2) — low storage cost burden, ideal for Rocket Growth.
Q4. Do category advantages differ between Coupang and SmartStore?
Yes. Coupang wins repeat-purchase items (consumables, baby) with Rocket badge; SmartStore wins search-comparison items (electronics, beauty, food). Run channel-specific strategies.
Q5. How to find low-competition keywords?
Type in Coupang search → check autocomplete. Demand/supply ratio ≥ 5 is viable. Use Naver Search Ads Tool (ads.naver.com); target keywords with 500–5,000 monthly searches as a beginner.
