Please Explain Attribution Model

[dlynch80]

In a segment I created there is a section called Attribution Model that allows me to select Repeating (default), Instance, and Non-Repeating Instance.  Please explain what each means and provide a simple example.

Hi @dlynch80 

please refer to the documentation here (> Attribution).

Sometimes the documentation is not great.

Let me start by use an eVar with Visit level expiration as an example:

• Page 1
  • eVar set to "x"
  • eVar Instance is triggered
• Page 2
  • eVar not set, but the value of "x" persists
  • eVar Instance is not triggered
• Page 3
  
  • eVar set to "y"
  • eVar Instance is triggered
• Page 4
  
  • eVar set to "y"
  • eVar Instance is triggered

You will notice that I showed both the eVar, and the specific eVar Instance metric (while you can access this metric directly, this is also part of what drives the behaviour of the attribution)

Repeating (default)

will count "x" as 2 and "y" as 2 (every time there is a value, regardless of being explicitly set)

Instance

This ties specifically into the Instance Metric associated to the eVar, every time the value is explicitly set, this will count it

So "x" will only count as 1 (from page 1, but not from page 2 since that is just persisted), and "y" will count as 2 (as both page 3 and 4 set the value explicitly)

Non-Repeating Instance

This uses the Instance, but excludes when the value is set to the same value as was previously set.

So "x" will count as 1 (same as above), and "y" will also count as "1" (page 4 is excluded because the value was the same as the previously set value)

Thank you.  What if I have a prop instead of an eVar in this scenario?

[Jennifer_Dungan]

Props are Hit level only, there is no concept of persistence... I don't think that the attribution setting will do anything for these... I believe they will return the same value no matter what (there is no "instance metric" for props)
