Google Analytics Cross Device Tracking Config

Question

Ok so with Universal Analytics out of beta I wanted to drop this question:

What is the best account, property and/or view set up to take advantage of cross device tracking? Explanation in the recent post on the GA blog:

http://analytics.blogspot.com/2014/04/universal-analytics-out-of-beta-into.html

I am aware that I have several options all explained here:

https://support.google.com/analytics/answer/2587087

However its not very clear as to which of those options is best to properly track sessions/users across devices. For example my big question is...do I really have to use the same GA code on all my apps to take advantage of this?

Or do I only have to create a property within the same account?

Any and all help would be most appreciated to myself and many others getting into UA.

Answer 1

Yes, you need add it in the 2 sites. But you need create a property Reference and Implement a Universal Analytics tracking code
