What are the different traffic types Post-IDFA?

You might be thinking, “What? Different traffic types? I thought it was just going to be SKAdNetwork compatible traffic!”

Well that’s the goal, not the reality.

The reality is that not everyone will be ready when iOS 14.5 kicks in. You see, traffic types will actually depend on two factors:

  • User device OS 
  • Publisher app compatibility with SKAdNetwork

Since not all users update their devices to iOS 14.5 from the get-go, nor will publishers update their apps from the start, we can expect to see different types of traffic on the supply side.

Specifically there will be three types of traffic:

Traffic TypeUser device OSPublisher compatibilityMeasurement
1. Post-ATTiOS 14.5 and aboveSKAN-compatibleSKAN
2. Pre-ATTiOS 14.4 and belowSKAN-compatible OR 
Not-SKAN-compatible
MMP
3. Non-measurableiOS 14.5 and aboveNot-SKAN-compatibleNon-measurable
ATT = App Tracking Transparency

Once Apple release iOS 14.5, based on past iOS releases, at Liftoff we expect the following to occur:

  • Post-ATT traffic will ramp up to 60% within the first 30 days. The majority of users will update their devices to iOS 14.5 and publishers who updated their apps to be SKAN compatible will see measurable traffic
  • Pre-ATT traffic will continue to exist until there are no more pre-iOS 14.5 devices 
  • Non-measurable traffic will represent a portion of overall traffic in the beginning and then shrink as publishers who did not update their ad network SDKs to be SKAN-compatible do so.

With iOS 14.5 just around the corner, it’s critical that everyone do their part to be ready. While what the user does is out of our control, what is in our control is getting every publisher to update their app to be SKAN compatible so that it’s SKAN compliant and more importantly, it’s measurable.
