The Johnson Door Company has a website named, JDoors.com. Last year, they released a mobile app available on both Android and iOS. They encourage users to use the app instead of the website because of its advanced capabilities. Currently, they advertise on YouTube and several other sites. When customers click on an ad, it takes them to JDoors.com instead of the app. What web technology can open a product URL directly in a mobile app?

Analysis of Correct Answer(s)

• Deep linking is the correct technology. It uses a specific Uniform Resource Identifier (URI) to send users directly to a particular screen or piece of content within a mobile app. In this scenario, JDoors.com can use deep links in their ads so that when a user with the app installed clicks the ad, it opens the relevant product page directly in the app instead of the mobile website. This creates a seamless and more engaging user experience, which aligns with the company's goal.

Analysis of Incorrect Options

• Universal links: This is a specific implementation of deep linking for iOS (Android has a similar concept called App Links). While technically a form of deep linking, "deep linking" is the broader, more universally correct term for the technology itself, making it the best answer.
• HTML5: This is the standard markup language for creating web pages. While essential for building the website, it is not the specific technology that connects a web URL to a location inside a native mobile app.
• Two-Factor authentication: This is a security measure that requires two forms of identification to grant access to an account. It is completely unrelated to linking between websites and mobile applications.
