What are examples of effective Shopify widgets?

Here are a few real-world examples that work well: A product-specific FAQ widget embedded under the “add to cart” button Review widget that shows user photos and ratings with filtering options A sticky cart summary on mobile to simplify checkout Bundle widget that lets users add complementary items with one click Trust badge bar that appears only during checkout or on high-ticket product pages Each of these adds value without overwhelming the page. Answer common questions, reinforce trust, or simplify actions: that’s the ultimate goal.
