Attribution of conversions to payment gateway in Google Analytics

[ViviCa1]

Hi all,

We have been having a problem for a while now where most transactions are attributed to referrals from our payment gateway Sagepay. The issue started a couple of months ago, when we finally upgraded our website to https:// for logged in users and transactions. Before, when we were using http://, transactions were attributed to the correct channel. Even weirder, we upgraded 4 websites and only 2 of them have the issue now, the other two continue to attribute transactions correctly.

I added Sagepay to the referral exclusion list which made no difference. Over the weekend, we upgraded to the global site tag and it seems to have improved somewhat, but yesterday 50% of transactions were still attributed to referral/sagepay.

I am also seeing an odd issue, where for half of the transactions, the revenue and transaction are attributed to one channel, but the products (quantity) are attributed to another. One of the channels is always referral/sagepay and the other is the channel that the transaction should be attributed to.

Has anyone seen this issue before? I'd appreciate any tips that might help us fix this issue.

Thanks in advance!

Hi Alick, thanks for your reply. That might be why we are seeing an improvement then as new visitors get attributed correctly, and only returning ones don't. I am just a bit concerned that this effectively means we have to wait 6 months to know for sure whether this fix is actually working 100%. But hopefully we'll see a gradual increase in the percentage of transactions getting attributed correctly, to give us an indication of whether or not it is working. Thanks!

Hi,

I faced the same issue and in order to resolve you need to add payment gateway site in referral exclusion list and wait for 6 months because The referral exclusion list is not working for returning visitors who already have the source set to the domain you added to the list. If they come back as direct they will still have that source set.

it will take six months for the domain you added to the referral exclusion list to disappear. Hope this helps.

Thanks
