“(rotating promotional banners as hero — no persistent trust signal or delivery promise)”
SEA shoppers distrust online marketplaces because of counterfeit goods and unreliable delivery. A carousel of sale banners does nothing to address either concern. The visitor sees promotions before they see proof that orders actually arrive.
“Pin a trust bar above the carousel: "LazMall: 100% authentic brands. Free returns within 15 days. Delivered in 3-5 days via Lazada Express."”
A persistent trust bar addresses the two biggest regional objections (fake goods + slow delivery) before the visitor processes any promotional content. Trust must precede transaction intent in low-trust markets.
