can google analytics tell me http referrer for each specific goal conversion?

Question

I have a website that allows people to create an account (that is the conversion I wish to track).

I wish to know where a specific person is coming from. I have google analytics installed and have set up the registration page as a goal, but the reporting tells me traffic sources as an aggregated pie chart. It doesn't report down to the user account level to say that 'person with email xyz' came from 'facebook' for example.

What custom variables or mark up would I need to add to GA to report at that detailed level, if that is at all possible?

Otherwise, I will just have to record the first http_referer in a cookie and stick it in a database during the registration process.

Any advice?

Answer 1

Firstly I must ask you, how actionable do you think it is to look at data at that granular of a level? Finding out what % of people who registered came from facebook or some other place is actionable, because it helps you do things like determine where to focus marketing efforts. But individual users? How is this actionable to you? (hint: it's not)

However, if you are still determined to know this, you should first note that it is against Google's ToS to record personally identifiable data both directly (recording the actual value in GA) or indirectly (e.g. - recording a unique id that you can use to tie to personal info stored within your own system). If this is something you don't want to risk, I suggest moving to another analytics tool that does not have this sort of thing in their ToS (e.g. Adobe SiteCatalyst, which costs money, or perhaps you may instead prefer to choose an "in-house" approach, like Piwik)

If you are still determined to follow through with this and hope not to get caught or whatever, Google Analytics doesn't record data like what info a visitor filled out in a form (like their email address) unless you populate that data in a custom field/dimension/metric/event to be sent along with the request. Usually you would populate this on the form "thank you" page (which is usually the same page you use as your goal url or goal event if you're popping and using an event for your goal). So you would populate the email address in one of those custom variables and then have it as a dimension to break down the http referrer by.
