Platform Dynamics & Liquidity Ranking

Understanding audience intent, sales velocity, and category restrictions across channels.

🏆 eBay Marketplace

Liquidity: Extremely High • 80–85% of listings sell as fixed-price Buy It Now. High search volume from buyers actively searching the exact model number (KN-550BT).

Key Benefit: eBay explicitly allows Over-The-Counter (OTC) FDA Class II blood pressure monitors in their Medical & Health categories, providing total listing stability without algorithmic takedowns.
🛡️ Facebook Marketplace & OfferUp

Liquidity: Moderate to High Local Demand • Buyers expect 30–50% off retail, but you pocket 100% of the cash price.

Policy Warning: Meta's Commerce Policy restricts medical device sales. To prevent automated bot bans, list under "Health & Beauty" or "Electronics / Smart Devices" and avoid triggering words like "medical grade" or "clinical treatment".
