Hey guys. I got one quick question. How much of a discrepancy can I expect between the clicks recording in
I noticed my data has been slightly off between 15% - 40% when it came to clicks/costs recorded from my traffic source and
Let me know.
I think it depends of traffic sources, countries and... hm... correct of links?
I don't know what should be but I have ~ same data of discrepancy (15%-40%)
Depends on geo and probably Internet connection.
As an example, for pops you get 15% clickloss from traffic source to
From 
But on average, 15-20% is still within normal range. Higher than that is not common and worth looking into a bit if you can fix anything. When I had it on some of our campaigns, I couldn't do anything about it. The affiliate network showed 50% less visits and that was it, no way to avoid it.
Rule of thumb is around 30%, some geos & sources combinations, like for example Thailand on Popads can give you up to 50% clickloss.
There us unfortunately nothing much you can do about it, so just have it in mind and count with it.
