The Definitive Guide to Mobile Deep Linking
The average consumer is spending five hours per day on their smartphones and this number is only going up.
We do everything on our phones these days, from shopping to browsing social media and managing our businesses.
This is why it’s more important than ever to optimize the user experience to keep people on your app for longer periods, enjoying it more, and sharing it with friends.
If you’re trying to optimize your mobile app, I’m sure you’ve already tinkered with the layout, fonts, copy, and more, but there’s one thing you probably haven’t…
Mobile deep linking.
It’s a small detail that can drastically enhance how users engage with your app but few are taking advantage of it.
That’s why I’m going to be teaching you what mobile deep linking is, why you need it, and how you can implement it yourself.
Let’s dive in.
What is mobile deep linking, anyways?
Mobile deep linking is the practice of funneling users deeper into your app through the use of a uniform resource identifier or URI for short.
This allows mobile app developers to push to a specific page within an application versus simply opening it.
Think of it as a website URL.
If you were trying to sell a product, would you want users landing on the homepage or being forwarded to a sales page found deeper in the website?
The latter, of course.
By helping users go to a certain page within an app, you’re making the customer journey easier by getting them closer to the end goal sooner.
Here’s a visual of what the process looks like:
While it might seem simple, mobile linking comes in three different forms that you need to be aware of. They include the following:
Standard deep linking
This is the straightforward deep linking that forwards a user to a specific part of the app. It’s also known as universal linking.
It only works if the customer already has the app installed.
The problem is within traditional linking is that when a user clicks a link, it won’t open the mobile app, but rather directs them to the browser version.
If someone is on a mobile device, the app version will always be more optimized and streamlined.
Here’s what happens if you search for my Instagram on Google for example with the app installed.
The results appear to be the exact same whether you have the Instagram app or not, but clicking it opens up the app seamlessly.
This is a good example of basic deep linking.
Someone that doesn’t have the Instagram mobile application installed will be given an error or redirected to a fallback page.
Deferred deep linking
This form of deep linking works the same way as standard linking does with the exception that it will direct users without the app to the download location.
This is beneficial because it can help app developers and companies acquire more customers.
Once the app is installed, the user will be referred to where they were originally navigating.
Check out the Skip The Dishes app to see what I mean.
While a user is creating their order, they are able to download the mobile app for Android or iOS.
They are forwarded back to the exact step they were taking, except in the mobile app after downloading it.
This means that they don’t have to manually go through the entire process again to get back to where they were.
Contextual deep linking
Contextual deep linking, also known as onboarding, is commonly used for gathering information on customers to personalize the user experience of an app.
Data such demographics, how users navigate to the app, and more is recorded.
The app onboarding process can be different depending on if the user installed via the Google Play Store, the Apple Store, a Facebook campaign, or another source.
A mobile app downloaded through a Facebook Ad might look different than when it’s downloaded through a Google Display Ad, for example.
The landing page is able to be customized through what is known as a deep view in mobile app development.
Just as the deep link forwards users to a specific deeper page in the application, the deep view is the visual result they see that’s different than others.
URI schemes
Deep linking is only doable thanks to what is known as URI schemes. These schemes are similar to how a website URL can direct you to a specific page on a website.
They look something like this:
See the fetched URI? Its format is appname://path/to/location.
Custom URIs are simple to set up for developers (Often created by default) and present the opportunity to redirect users wherever you please.
The mobile customer journey and how it applies to deep linking
The mobile buyer’s journey is the individual’s steps a user takes to find, use, and share your application.
It’s similar to the regular funnel a customer goes through when purchasing a product with some small differences you need to be aware of.
Here’s how the various steps in the mobile buyer’s journey can be applied to mobile deep linking.
Discovery
The first step in the mobile customer journey is discovering your app in the first place.
While this can be achieved through strategies like content marketing and SEO, deep linking gives you a nice boost to these tactics.
Google indexes deep links from mobile apps, giving you more opportunities to rank and drive organic traffic.
Users can click the search engine listing and open the link directly through the app instead of an internet browser.
Look at this search for Google Analytics to see what I mean:
This helps businesses acquire more users and increase brand awareness versus having a single search engine listing.

Compare
Once a user has narrowed down a few options, they’re naturally going to want to find the best app by comparing them.
They’ll look at factors such as pricing, ease of use, and features.
Deep linking enables you to push users to the best features of your app, reviews, or customize the experience to make your application better than competitors.
By reducing the number of steps it takes to get to important functions of the app, you’re also decreasing the chance of users bouncing.
Decision
The third step in the mobile buyer’s journey is making a decision and commitment to a single app.
Having a clear value proposition and refined user experience is crucial here.
Better yet, contextual deep linking helps you collect data to make the application as tailored as possible to your buyer’s persona.
Marketing campaigns can also be optimized with this information to improve targeting and performance.
Retain
Once you begin acquiring more users, you need to keep them.
Standard and deferred deep linking will help navigate users back to your app when they are on search engines, social media, and other platforms.
This keeps them using your app more often.
Data that can be collected as a result of deep links will assist you in understanding why and how they use your mobile application.
Doubling down on these is what we call Pareto’s Principle or the 80/20 rule.
This rule can be seen everywhere and defines that 80% of results come from 20% of actions.
In the case of mobile app development, you might discover that users are only engaging with a few features and others are taking up space.
You could hypothetically update the features and pages that are used the most, boosting engagement and retention.
Businesses will miss out on discovers like this if they don’t use deep links to collect information.
Why mobile deep linking matters
I know what you’re thinking.
“Why should I bother with mobile deep linking?”
Let me explain.
It improves the user experience
If you can save the user from going through multiple steps instead of one, why wouldn’t you?
That’s exactly what deep linking does, and improves UX because of it.
You’re making the life of users easier by using deep linking to get them where they want to go faster.
This gives them a better experience and impression with your app as a result.
Here’s what the difference between not using mobile deep linking and taking advantage of it looks like:
Much simpler, right?
This brings me to my next point.
It increases customer retention and engagement
Wouldn’t it be nice if every user that downloaded your app stay active all year round?
Unfortunately, that’s not how it works.
It’s been found that 55% of users will churn after the first month of use. That means nearly half of the new downloads will be lost.
Look at mobile app user retention the same way you approach a website.
It’s common for nearly half of all visitors to leave a website and not take any action.
Do you just sit there and do nothing about it? Of course not!
You implement strategies like email options through popups and exclusive content to capture those users before they leave.
This is precisely what deep linking can be used for but in the sense for a mobile app.
Once a user has visited your app, you can retarget them and use a different style of deep linking to improve their experience.
It improves the onboarding of new users
When a mobile app uses a form of deep linking like the deferred approach, you are capable of acquiring more users.
This is because as a user goes through the mobile browser version of your application, they will be given the option or automatically forwarded to the appropriate download location.
The contextual linking technique can be used to onboard new users in different ways depending on where they originally download the app from.
If you understand that users coming from a Facebook ad campaign regularly navigate to a certain product category, you can push them there automatically.
Furthermore, perhaps users from Google like to learn more about your business first before purchasing.
You can use contextual deep linking to direct those users to the page detailing your company’s history.
You can re-engage users
Once a user has used your app, you have a small window of opportunity to retarget them.
Did you know that 46% of search engine marketers believe that retargeting is the most underused form of marketing right now?
It’s a hidden gem that deep linking enhances.
If a segment of users downloaded your app, viewed product pages, and bounced, you could retarget them in advertising campaigns and use deferred linking to forward them back to the high-interest product pages.
Strengthens your marketing
Personalization is key. Contextual deep linking allows you to customize the user experience, which improves marketing results.
Take into consideration that 39% of consumers will spend more money when given a mobile coupon.
You could collect data on users via contextual deep linking to discover what product categories they enjoy the most, then offer a discount for them to align with this behavior.
Similarly, mobile deep linking has the potential to increase conversion rates.
This is because you are pushing users through the sales funnel quicker. Normally this consists of:
- The user lands on the homepage of your website.
- They navigate to a product page and add a line item to their cart.
- They visit the cart page to confirm their order.
- Finally, they pay and check out.
Mobile deep linking can effectively cut the sales funnel in half by helping customers go straight to sales pages.
Take the ticket mobile app SeatGeek as an example. They were able to increase revenue by 10.6% and app open rate by 8.8% with deep linking.
Here’s how…
Firstly, they struggled with reminding users to finish their purchases and buy tickets through the app.
They resolved this issue by using deep linked mobile ads. These target ads based on past user activity would display relevant ads in other existing apps the customer used.
SeatGeek noticed that they were getting thousands of new users per day and had to keep them.
Their team began creating ads that would serve different audiences based on previous behavior.
An example of this would be a user adding tickets to their favorite basketball team’s game to cart, but then abandoning before checking out.
When this user was on another application that supported ads, they would see an advertisement for that same basketball game.
The ads were simple in nature, using a related image, and straight forward call to action.
Boosts app discoverability
Don’t you want to get discovered by more customers?
Of course, you do!
And that’s precisely why you need to implement more deep linking in your mobile app.
Deep links are indexed on Google, giving you more opportunities to rank and drive traffic to your business.
And seeing as Google receives over four billion searches per day, you don’t want to miss out on the free exposure.
Think about how a website like mine ranks for thousands of pages, and not just the homepage.
You can achieve that same performance but for your mobile app.
Users on search engines like Google will be able to visit deeper functions and features versus landing on the welcome page.
This creates the opportunity to optimize applications for SEO via keywords, meta descriptions, and title tags, as well.
Provides analytics and insight into campaigns
Mobile deep linking allows you to refine your buyer’s persona and better understand their behavior.
This information can be used to improve the effectiveness of marketing campaigns and the overall experience of your app.
You will also be able to discover which links are being clicked the most and by whom.
Doing so creates the opportunity to double down on the best-performing links and optimizing who you target in advertising campaigns.
Deep links also shine light in which parts of your app are used the most and which aren’t.
Google offers its Firebase product to track deep linking in an easy to use platform.
You can begin using it by selecting the Android, iOS, C++, web, or Unity options.
Using Android as an example, you will need to ensure that you meet the prerequisites Google outlines in their documentation.
Firebase’s SDK automatically captures various metrics, user properties, and allows you to create custom events if you wish to track a specific action.
This data is then relayed through the Firebase dashboard which has a very familiar look and feel to other Google products.
You will feel right at home if you’ve ever used Google Analytics.
Which by the way can be connected to Firebase if you need to add events specific to your business like e-commerce purchases.
How to perform mobile deep linking
Now that you’re excited to get started using mobile deep links, here’s how to implement it yourself.
Deep linking on Android
Android devices will select one of three options when a URI is requested:
- It opens a preselected app with the URI.
- It opens the only available app that can handle the URI.
- The user is prompted to choose an available app.
To begin adding deep links to achieve this, you will need to navigate to the AndroidManifest.xml file of your Android mobile app.
You will then have to add the following elements to the file through an intent filter:
- Specify the ACTION_VIEW attribute in the <action> element.
- <data> tags which include the URI scheme, host, and path.
- CATEGORY_DEFAULT and CATEGORY_BROWSABLE attributes to move users from a browser to your app.
Here’s an example from Android’s official documentation on deep linking of what the code will look like:
The second step is to ensure that your app can read data from the intent filter you created.
This is achieved through adding getData() and getAction() methods like so:
Deep links should not require users to log in or perform other actions to visit the desired content unless desired like in the case of promoting app downloads through deferred linking.
iOS
Adding deep links to iOS apps begins by enabling them through what is known as Associated Domains Entitlement.
That’s a fancy way to say you’re letting search engines know what app belongs to what website.
This way when a user clicks on your website, it activates the specified type of deep linking you choose.
You will then have to add an Apple App Site Association file to your website to verify it.
This association file needs to contain the following code, as you can see from Apple’s official documentation:
Similar to how Android apps have the manifest file, the app delegate file acts as the root of iOS apps.
This is why you will have to program your app delegate file to respond to deep links like Apple shows in this example:
They are specifically handled through the NSUserActivity object and activityType value of NSUserActivityTypeBrowsingWeb.
Your iOS app will be prepared to handle and accept users that navigate to it from browsers like Safari after you complete these steps.
Conclusion
Mobile deep linking is a powerful technique to improve the user experience, on-boarding, and marketing of applications.
The three types of mobile deep linking are standard, deferred, and contextual. It’s important to understand each of these to know when to use them properly.
Standard deep linking is used when customers already have an app installed. When they click on a mobile link, it will give them the option to open it in the app or automatically.
Deferred deep linking works by forwarding users to the appropriate app store to download the app if they don’t have it, then pushing them to the originally intended page.
Contextual linking is the most complicated but allows developers to collection information on users to customize the on-boarding and overall experience of the app.
Mobile deep linking can be implemented in each step of the buyer’s journey to acquire and retain users, too.
