What counts as a view? Should a banner appear on a screen or only a part of it? Does the user need to watch the full video or are a few seconds enough to be considered a view? Even when it comes to clicks, it isn't so straightforward: what should happen after or before the click so it is considered viable?
This article provides information about the following:
- AppsFlyer recommended standards on defining a click or view
- How to send AppsFlyer the details of ad visibility during the engagement
Definition of clicks and views
Each ad network defines clicks and views differently. This can cause inconsistent and incomplete data.
Example
A campaign for AwesomeApp includes a video ad that is 10 seconds long.
A user sees the ad on two different networks — first on Network A, then, after a while, on Network B. Each time the user watches it for 4 seconds.
After seeing the ad on Network B, the user downloads AwesomeApp and goes straight to the app store.
Network A counts a view for a video ad when at least 4 seconds of it has been watched.
Network B counts a view for a video ad as 50% of its duration.
Network A is reporting this as a view and gets the attribution. Network B doesn't report it, although most likely it motivated the user to download the app.
If both networks have the same definition of a view, both would report the engagement. The attribution is awarded to the most recent view.
For fairness and consistency, AppsFlyer recommends that its partner networks adopt the following standards:
| Ad type | View | Click |
|---|---|---|
| Interstitials and banners | 50% of the ad unit is visible for 1 second | A click that takes the user directly to the app store |
| Rewarded videos |
Video is watched for 2 seconds |
A click that takes the user directly to the app store |
|
Playable ads |
The playable element is launched |
A click that takes the user directly to the app store |
|
Standard video |
Video is watched for 2 seconds |
A click that takes the user directly to the app store |
Ad networks are encouraged to send ad visibility data per click or view to give advertisers a better understanding of user engagement and assists in campaign optimization. See how networks define clicks and views.
Send engagement parameters
Append the af_ad_type parameter to the click/view URL with the value that indicates the ad type that the user engaged with. See URL examples that follow.
Depending on the ad type, you can attach the relevant engagement parameters that provide details of the engagement (e.g. how much of a video a user has watched).
