eBay's breakthrough was creating trust in a space with none. Its two way ratings, star tiers, and seller metrics made trust measurable and raised prices for reliable sellers. PayPal protection, identity checks, fraud tools, and dispute resolution reduced the risk of bad transactions. Over time, this trust system became a moat that kept users on the platform and set the template for Airbnb, Uber, and Etsy.
