What is checkout optimization for digital products?

Checkout optimization for digital products is the process of reducing friction between a buyer's intent and a completed payment, tuned for instant delivery goods like templates, courses, and AI prompts. Unlike physical commerce, there is no shipping delay or inventory issue to blame; every lost sale is a UX or trust failure. Winning setups use a streamlined single screen, clear product previews, social proof near the buy button, and fast payment options like Apple Pay or Stripe Link.
