Can I use A/B testing to optimize my Shopify popup designs?

Full-screen popups on Shopify can hurt user experience if they’re poorly timed or too aggressive. They block content, frustrate visitors, and often lead to higher bounce rates, especially on mobile. But when used wisely, like offering a genuine discount or capturing emails after someone scrolls, they can boost conversions without annoying shoppers. The key is to avoid bombarding users by making the popup feel helpful, not pushy.
