I stored the Page ID value in Prop and eVar.
The Page Views, Visits, and Unique Visitors values of Prop and eVar are different.
I want to know the why. please reply.
There are a few different things that could affect these to have different results between an eVar and a prop.
1. If the prop or the eVar isn't fired on some pages.
ex 1: Lets say an eVar was already set before visiting this page and the visitor visits a page without a prop set the eVar will be passed and the prop wont be.
ex 2: If its a page where the eVar isn't set and prop is and this is the first page of the visit the prop will be sent but the eVar won't.
2. If the expiration of the eVar is set to a certain time limit where they can pass new values through it.
Looks like you have this set up to visit, so you shouldn't have a problem with this.
If this doesn't answer your question please email client care at:
