This is an extremely important feature for every Nation that wants to use Google Analytics Advanced Ecommerce on their website. GA ecommerce can NOT track across 3 domains. The source is broken after 2 even if you have cross domain tracking setup properly with the proper domains added to the referral exclusion lists. Three es no bueno.

So if my website is on: DomainXYZ.com and then someone clicks to donate and goes to DomainXYZ.NationBuilder.com and then makes a purchase via PayPal and are directed through the PayPal.com domain, even if you add all of these to your domain exclusion list, the purchase is still tracked as “direct/none” traffic source and/or tracked back to just the original page on the main domain, but NOT the traffic source that brought someone to that page on your domain.

Basically instead of a Traffic report saying:

Twitter -> Blog Post ABC --> Donation Page -> PayPal—-> Thank You After Donation

The Traffic report will say:

Blog Post ABC -> Donation Page -> PayPal—-> Thank You After Donation

And another session with:

Twitter -> Blog Post ABC—> Website Exit

// It basically won’t stitch together the original source data and it splits it out into two sessions. Double counting sessions in google analytics … eek.

Some of us folks may not be on the enterprise plan but we’d definitely like to be using Google Analytics Advanced Ecommerce and prevent double session issues :)

Thanks for considering elevating this feature to get donate pages on our own domain so we can drop down to 2 max domains in a donation funnel for PayPal.
