How to Measure Install Ads Performance for Subscription Apps

Grow your high-quality subscriber base with the right app install ads campaigns. How to do it? Let’s begin by measuring the actual value of each ad campaign.

As an app marketer or growth manager, you acquire app users from paid install ads platforms: App Store, Google Play Store, Facebook, Tiktok, Reddit, Instagram and so on. 

However, with so many install ads campaigns, how can you measure their performance individually? “Track the installs”, you may answer. Well, that’s partly true. But installs don’t necessarily mean revenue for subscription apps. So besides tracking installs, you also need to track the post-install events of paid acquisitions, one of which is generating revenue.

Measure Install Ads Performance by Tracking Installs

It is obvious that the basic goal for install ads is to entice users to install the app. Even though installs don’t necessarily mean high-quality users, they are an important indicator of the install ads' performance.

That’s why ads platforms offer the install report for you. You can see how many installations are from each ad campaign clearly, so you will get a general idea of your ads campaign performance.     

If you are using several ad platforms and want to see all the install data on one dashboard in real time, you can make use of mobile attribution and analytics tools, such as Adjust and AppsFlyer, which offer solutions to attribute user acquisition across platforms. From the dashboard, you can know where your most valuable users are coming from and which marketing channels perform better in acquiring installs.

While keeping taps on the install numbers in different ad channels and campaigns, you should also track their post-install events respectively, in order to understand their true value. 

Measure Install Ads Performance with Post Install Events

As mentioned above, merely tracking installs can not tell you whether you gain profits from install ads or you are just wasting your marketing budget.

To further explain, if users download your app but don’t even launch it before they delete it, App companies will not get any revenue from these kinds of installs. That’s why a simple analysis of the number of installs is not enough for understanding the success of the ads channels and campaigns.

Post-install events, in this case, can help evaluate the real value of the acquisition ads, let’s see what they are for subscription apps and how you can measure them across platforms. 

Post-Install Events for Subscription Apps

Post-install events are what users do in your apps after they click the ads and install your app. For subscription apps, the main crucial post-install events we need to keep an eye on are trials, subscriptions, and renewals. Other in-app events to track depend on your app service. 

For example, if your app offers subscriptions for digital books, apart from subscription events, you may also want to track whether users have clicked on the book and read the content after they launch the app.

Track Post-install Events Using for Subscription Apps

Tracking post-install events for subscription apps can be time-consuming and require much technical work. However, if you are using the right kind of tools, things will be easy.

Turn the toggle button “on” or “off” at the right of the event name to decide whether the event will appear on the funnel.

    Note that if you are tracking the custom events, you should drag the events from the “Available event” list to the top “Select up to 5 events” (Yes, that’s right, you can create up to 5 events to be in the funnel);

  • Check the report: on the funnel, you can see the event names, the exact count of the events and the conversion rate between each event.

    Below the bottom, you can choose to view the data at the views of “Next level” or “Day”.

    From the “Next level” report, you can see more detailed data on the next level, for example, if you choose the post-install funnel at the “All Channels” level, you can see the post-install events of every channel—Facebook ads, Google ads, Apple Search Ads, organic, etc.

From the “Day” report, you can see the post-install event data by day.

Check the RoA: at the right bottom of the funnel, you can see the “Check your RoA”, clicking it will lead you to the RoA report where you can see the return of advertisement.
