Homepages get workshops. Hero sections get A/B tested for a quarter. The cart page — the one place on the entire store where a visitor has already decided to buy something — usually looks exactly like the theme’s default, because nobody thought to open the file.
The one page with a captive audience
The cart is the one page on the store where every visitor has already decided to buy something. That is a completely different design problem to a homepage, which exists to earn attention from someone who hasn’t decided anything yet. The cart’s only job is to not lose the decision that has already been made.
Where it loses people
- A shipping cost that only appears at the next step
- No visible way to apply a promo code without opening a new tab to find one
- Quantity steppers small enough to mis-tap on a phone
- No indication of how close the order is to free shipping, if that exists
None of these are hard to fix. They are just never on anyone’s list, because “the cart” does not feel like a page someone designs.
Treat it like the homepage
Same rigor, same review, same willingness to test a variant. It has a smaller audience than the homepage and a much higher intent — that trade is almost always worth taking.
