👉🏻 Mandatory sign-up: This adds too much friction to the checkout, and it will likely make you lose impulsive purchases. When you ask them to go through a sign-up process, they’ll start thinking about their decision again. Keep it simple.

👉🏻 Too many upsells: Putting too much pressure on buyers with too many upsells might scare them away and make for a bad experience.

👉🏻 Not being mobile-friendly: We shouldn’t even be talking about this in 2022, but yes… optimise your website for a mobile-first experience. Make sure that your CTAs, images, text, and every element look well both on mobile and desktop.
