prop 6 and evar 6 is assigned to unspecified even though it has the value

[m2masari]

Hi ,

On Prop6, a notable number of unique visitors are designated as 'unspecified.' However, upon examining the URL level, I've noticed that these URLs have Prop 6 assigned to a  country. Why does this discrepancy occur?

 

when I use evar 6, this numbers is lower but still notable However, upon examining the URL level, I've noticed that these URLs have evar 6 assigned to a country so Why does this discrepancy occur?

And also which one to use evar 6 or prop 6? What is the difference?

Thank you

You're Page URL "v1" looks like eVar1... are you sure your eVar is set to HIT expiry, and not the default "VISIT" level expiry?

Visit expiry would maintain the previous value until a new value is written.. in this case, it's entirely possible that the URL you are seeing in the report is not the place where you are missing Page Country (c6)

Try adding the metric "Page URL Instances", if the eVar value is carried forward, then you should end up with 0 instances.... if its actually being set, then you should have data.

Sample:

• Page 1
  • Prop6 set to "value"
  • eVar1 set to "www.domain.com/" 
  • eVar1 Instances incremented
  • Page View / Unique Visitor metrics collected
• Page 2
  • Prop6 set to "value2"
  • eVar1 set to "www.domain.com/page2" 
  • eVar1 Instances incremented
  • Page View / Unique Visitor metrics collected
• Page 3
  • Prop6 fails to be set, therefore value is null or unspecified
  • eVar1 is NOT set, but maintains last value of "www.domain.com/page2" due to Visit expiry
  • eVar1 Instances is NOT incremented
  • Page View / Unique Visitor metrics collected
• Action 1
  • Prop6 fails to be set, therefore value is null or unspecified
  • eVar1 is NOT set, but maintains last value of "www.domain.com/page2" due to Visit expiry
  • eVar1 Instances is NOT incremented
  • Page View / Unique Visitor metrics collected
• Page 4
  • Prop6 set to "value3"
  • eVar1 set to "www.domain.com/page4" 
  • eVar1 Instances incremented
  • Page View / Unique Visitor metrics collected

So you can see that on Page 3 and Action 1, neither prop nor eVar were set, but the eVar still has a value due to the expiry telling it to keep the last set value....

But in this case, the "Instance" of the eVar will not increment
