All e-commerce referrals are my own domain

[andyg1]

Hello,

I am using Google Analytics to track referrals to my e-commerce website. The site uses a 3rd party payment processor, www.secpay.com, for the last two pages in the shopping cart - the Credit Card verification and the confirmation pages.

The e-commerce tracking aspect of the Analytics has always worked. It records the amounts and the products correctly. However the referral source of the transactions are always my own domain. i.e. the domain of my website. Something is wrong. (This is one step better than it used to be, where all the referrals used to be "direct"). Google were helping to begin with, but seem to have given up on me now. This is counterproductive from them because if I don't know what my referral source is then I may as well stop throwing hundreds of pounds into my Adwords campaigns then!!

I have searched the Internet high and low for people using Analytics with SECPay, and have contacted SECPay themselves. No joy.

Can anyone help me explain why all the referring sources are my own domain?

Just some points of clarification:
- the credit card page is hosted on the SECPay server
- the confirmation page is pulled from my server, but displayed in the SECPay domain
- the credit card page does allow Javascript
- the SECPay credit card page is NOT in frames
- I am using the parameters
_udn="none";
_ulink=1;
in my Analytics code
- the submit button that takes the user from my site to SECPay is using the onSubmit="javascript:__utmLinkPost(this)" code

I am totally lost with this, and may aswell be throwing my money down the drain if I can't the ROI of my marketing.

Please if anyone can shed any light on this then I will be eternally in your debt.

Andy
