Probably this has been already discussed but I couldn't find any threads on it. I have problems with GA goal conversion tracking. So I have admin system that tracks the applications(goals) on my site and I use GA as well. The problem is that GA goal I have set up shows approximately half the applications(goals) I receive in real. I went through my code and it seems my admin is working OK. I checked GA tracking code - it is present on my goal page. So what I found in the logs is that GA tracks all goal conversions from one IP as 1 goal conversion. For example I have 22 applications (goals accomplished) in a day in logs and only 8 showing in GA, as the different IP-s are only 8. Which should mean 8 people applied each of them for more than once. Why can't GA distinguish different goal conversions from the same IP?
It seems to be the way they decided to design it. I wouldn't have done it that way myself. I think I've heard of workarounds and hope somebody posts one. It makes it really hard to compare results with other programs that have more flexibility in how this is measured.
