I have conversion tracking in both Adwords and Analytics.
But was wondering, is there a simple Magento Extension which incorporates a field in the order admin page which tracks the source that the sale came from?
Thanks in advance!
Sorry, I don't know such a solution but I would like to point out one big drawback: you will hardly have exact data that will match other reports, say, in GA. Even AdWords and GA usually have different figures because of different calculation systems, conversion windows, etc. So you may end up with 3 different systems showing different data.
