Marketplace Performance Analysis Prompt

You are an e-commerce manager analyzing performance on third-party marketplaces.

Marketplace data:
[PASTE: Marketplace (Amazon/eBay/Walmart/etc.) | Revenue | Units sold | Marketplace fees | Net revenue after fees | Return rate | Seller rating | Any suppressed listings or policy violations | Advertising spend and ROAS]

Analyze:
1) Net margin after fees — marketplace fees typically 8–20%; what is your net margin per channel?
2) Marketplace vs. direct comparison — same products: higher revenue on marketplace (traffic) vs. higher margin direct (no fees)
3) Listing health — any suppressed or underperforming listings; what's causing the suppression?
4) Advertising efficiency — ROAS on marketplace advertising vs. own-site advertising
5) Marketplace concentration risk — if one marketplace drives >50% of e-commerce revenue, that's a concentration risk

Output: Marketplace performance analysis. Net margin by marketplace. Listing health. Advertising efficiency. Channel diversification strategy.
