So this means that ROI tracking is very limited in the absence of a tracking url e.g.?referrer=soandso

I would be interested in any comparison percentages.
e.g. I make mine about 50% untrackable. Like I said, I'm amazed its so high. Until today I was sure we had a weakness in our tracking system.

So, those of you tracking natural (non sponsored) conversions, what is your tracking success percentage?
