小米是 ScaryBooks.com 的行銷人。Google 流程報表顯示，有很高比例的使用者會在結帳時放棄購買商品。小米認為原因在於使用者每次購物結帳時，都必須填寫所有關於運送、帳單及信用卡的資訊。 哪一項 Google 解決方案可大幅加快 ScaryBooks.com 的結帳程序？

One Tap Sign-up significantly speeds up the checkout process by allowing users to sign in or create an account with a single tap using their existing Google credentials. This eliminates the need for users to manually enter shipping, billing, and credit card information repeatedly, which is the core problem identified by小米. Google AI is a broad term for various AI technologies and wouldn't directly streamline a checkout process in this manner. Progressive Web Apps (PWAs) enhance website performance and user experience but don't specifically address the issue of repeated data entry during checkout. Google App Engine is a platform for building and hosting web applications and isn't a user-facing solution for checkout optimization.
