Deep links are URLs that direct users to a specific page or content within a website or app, rather than just the homepage. This allows for easier navigation and access to relevant information, enhancing the user experience. For example, a deep link can take you directly to a product page on an e-commerce site, rather than making you search through the homepage. In mobile applications, deep links can also connect users to specific content within the app, even if the app is not currently installed. This is particularly useful for marketing campaigns, as it can lead to higher engagement and conversion rates by guiding users directly to the desired content, such as a specific article or video within the app.
