According to Similarweb, which tracks website data, nine out of ten US visitors on Temu’s and Shein’s websites during the holiday season end up as window-shoppers, not buyers. As of October, both retailers have a 4.5% and 4.1% conversion rate, respectively.

Meanwhile, Amazon leads holiday shopping with a 56% conversion rate, fueled by expansive product categories, fast shipping, and customer-friendly return policies.
