Title: Deep Linking Author: Kriko Published: Feb 5, 2021 Last modified: Jul 14, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. D Letter # Deep Linking **Deep linking** is a link structure that directs users to a specific piece of content, product, category, campaign or app screen instead of sending them to the homepage of a website or mobile application. With this structure, users can reach the content they are looking for directly, without having to navigate through several steps. It is an important technique that improves user experience, especially in e-commerce, media, finance, travel, food delivery, marketplace and mobile app-based businesses. On the web, deep linking can be explained as directing a user to a specific product, article, category or content page instead of the homepage. For example, when you send a friend the URL of a specific product on an e-commerce website, that link takes the user directly to the product detail page rather than the website homepage. In a broad sense, this is an example of deep linking. However, in digital marketing and the app ecosystem, the concept of deep linking is more commonly associated with directing users to specific screens inside a mobile application. In mobile applications, deep linking takes the user directly to the relevant content after the app opens. For example, when a user wants to share a shoe, news article, hotel page or campaign screen inside a mobile app, a deep link allows the person who clicks the link to reach that exact content. Without deep linking, the user would have to open the app, go to the homepage, search or navigate through menus to find the content. This lengthens the user journey and can reduce the likelihood of conversion. Deep linking provides important advantages, especially in marketing campaigns. Users coming from email, SMS, push notifications, social media ads, Google Ads, QR codes, influencer posts or remarketing campaigns can be directed straight to the relevant product or campaign screen. For example, when a user clicks a “Complete your cart” message, sending them directly to the cart screen instead of the app homepage creates a better experience. This structure can improve conversion rate and campaign efficiency. The main types of deep linking are usually explained as traditional, deferred and contextual deep linking. A **traditional deep link** directs the user to a specific screen inside the app if the app is already installed. However, if the app is not installed on the device, the link may not work, may return an error or may fail to take the user to the right place. For this reason, traditional deep links work best in scenarios where the app is already installed on the device. Traditional deep links can use custom URL scheme structures. For example, an app may open a specific product page with a structure such as `brand://product/12345`. When the user clicks this link, the device tries to open the related app. However, if the app is not installed, the device may not be able to interpret the link. For this reason, deep linking based only on custom URL schemes can be limited in app install and user acquisition scenarios. **Deferred deep linking** is a structure where the user is directed to the relevant in-app screen if the app is already installed. If the app is not installed, the user is first directed to an app store such as the App Store or Google Play. After installing and opening the app, the user is then taken, whenever possible, to the product, campaign or content screen they originally clicked. The term “deferred” comes from the fact that the final content destination is reached after the app installation process. Deferred deep linking is especially valuable in user acquisition campaigns. For example, if an ad promotes a specific product, discount or piece of content, the user should reach that same content after installing the app. Otherwise, when the user opens the app, they land on the homepage and need to search again for the product they were interested in. This can weaken the first experience. Deferred deep linking preserves continuity between the advertising promise and the in-app experience. **Contextual deep linking** not only directs the user to the target content, but can also carry additional information about the context of the link. This information may include campaign source, advertising channel, user segment, referral code, discount code, referring user, location or content type. This means the user is not only sent to the right page, but can also receive a personalized experience based on the context of the referral. Referral campaigns are a common example of contextual deep linking. When a user sends an app invitation link to a friend, the person who clicks the link can be directed to the right screen after downloading and opening the app, while the referral code can also be applied automatically. Similarly, a user coming from a discount campaign can be directed to the relevant category when the app opens and be welcomed with the campaign code already applied. This structure provides a more advanced experience for marketing measurement and personalization. In the modern mobile ecosystem, deep linking is not limited to custom URL schemes. More reliable structures such as Universal Links on iOS and App Links on Android are also used. These structures create a more controlled relationship between web URLs and the mobile app experience. If the app is installed, the link can open inside the app; if it is not installed, alternative flows such as the web page or app store can be configured. Therefore, a deep linking strategy should be planned by considering both web and app experiences together. Deep linking is important not only technically, but also for measurement. It can help analyse which campaigns drive app opens, which links generate installs, which users reach the target content and which referrals produce conversions. Mobile measurement and attribution solutions such as Adjust, AppsFlyer, Firebase, Branch or similar platforms can be used in this process. However, when measurement is implemented, user privacy, permissions, platform policies and data protection rules should be considered. If deep linking is not configured correctly, user experience problems can occur. Common issues include links failing when the app is not installed, users being sent to the wrong screen, the target content being lost after app installation, campaign parameters not being carried over or inconsistent experiences between mobile web and app. For this reason, deep links should be tested across different devices, operating systems, browsers and app installation scenarios before being published. In summary, **deep linking** is a link structure that takes users directly to the relevant web or app content instead of the homepage. On the web, a specific product or content URL can be a simple example of this logic; on mobile, deep linking is used to direct users to the correct screen inside an application. Traditional, deferred and contextual deep linking types serve different scenarios. When implemented correctly, deep linking shortens the user journey, improves campaign performance, supports in-app conversions and makes marketing measurement more meaningful. ## Discover it in the dictionary ### Data Science Data science is an interdisciplinary field that aims to extract meaningful, usable and actionable insights from data.
