TuneStreamer.com is an online music streaming site. Subscription orders are declining steadily. As the lead marketer for the site, it's your job to determine the cause and solve the problem. Google Analytics reports seem to indicate that friction on the checkout page is high. Apparently, something about the checkout experience is turning customers away. Which Google feature can make checkout easier by using information stored in the user's Google account?

Analysis of Correct Answer(s) - One Tap sign-in: This is the correct solution. Google One Tap is a feature from Google Identity Services that allows users to sign up or sign in to a website with a single click. By using the user's active Google session, it can pre-fill information and bypass the need for manual form completion or password creation. This directly addresses the problem of high checkout friction by making the sign-in and account creation process seamless, thus simplifying the overall checkout experience.

Analysis of Incorrect Options - Google Analytics: This is a powerful web analytics tool used to track and report website traffic. It is excellent for identifying problems, such as a high drop-off rate on the checkout page, but it does not offer a feature to actively solve the friction itself. - Multi-factor authentication: This is a security measure that adds a layer of protection by requiring two or more verification methods. While important for security, it inherently adds a step to the login process, thereby increasing friction rather than reducing it. - Google Shopping Cart: This is not a feature that external websites can integrate to simplify their native checkout process. It is part of the Google Shopping platform itself and is not a universal solution for third-party e-commerce sites.
