That’s because nobody shops in independent stores in China. Sure, private traffic is a buzzword. But over 70% of all ecommerce happens on just Tmall & JD alone. It’s rare for people to shop on independent sites.
But there is no passive way to participate in Tmall. Maintenance #costs & set up fees are high compared to the US. Promotional events play a major role in every store and require active involvement of a Tmall marketing & operations team.
