Let's say you have lots of mini-sites (one page, "click here to buy").
If you look at Awstats, it has "Unique Visitors" & "Number of Visits".
Looking at Webalizer, it only shows "Visits" and between the two stats systems, their numbers don't necessarily match (although some numbers come close) and I have a few sites numbers aren't close at all usually Webalizer being greater in number of "Visits".
So my question is if you want to calculate number of sales per every 100 visitors, which one should be used?
Perhaps only the "Unique Visitors" shown in Awstats?
