Deep linking is a technique that enables users to access specific content or features within an app or website, rather than simply landing on the homepage or main page. This is achieved through the use of a unique URL or link that directs users to a specific section or page within the app or website. Deep linking has become increasingly popular in recent years, as it provides a seamless and intuitive way for users to access the content they want, without having to navigate through multiple pages or menus.
