Can you be more exact about the meaning of success rate?
Is it click thru rate,
conversion rate,
number of sales,
turnover
?
I am Jumping on this post as - ideally - I would like to know how Success Rate is calculated and the units used.
I can't think of a reason not to give units like epc... ... ?
You may be using catagory averages to adjust numbers between catagories with widely different volumes.
Thank you.
