You're a marketer for your company's website, Smith&Smith.com, a shoe wholesaler. Google Analytics has shown that the exit rate on the checkout page is high. In a meeting with the developer team, you explained that this means the checkout page is unfriendly to customers. You've recommended that they implement a one-click-to-buy option that utilizes information stored in the users account. Which type of user personalization is this known as?

Using given information" refers to leveraging data already provided by the user (e.g., shipping address, payment details stored in their account) to streamline future interactions. A one-click-to-buy option that uses stored account information is a prime example, as it reduces friction by pre-filling fields and simplifying the purchase process. This directly addresses a high exit rate on a checkout page by making it easier for returning customers to complete their purchase. "Progressive checkout" involves gradually collecting information from the user over time, not necessarily using pre-existing stored data for a single-click purchase. "Dynamic merchant processing" relates to how payments are handled by the merchant system, not the user experience of the checkout itself. "Static profile matching" is a broader term for comparing user profiles, but doesn't specifically describe the act of using stored data for a one-click purchase.
