I have two sites that are at ranging all over the place, i have yet to figure out the variables. very wide range.
one is 4 yrs old and doing around 1500 uniques a day. total hits for the month are anywhere from 1.5 million to 2million. bots are excluded in the count.
its also gets anywhere from 5 to 35 new members a day. some of these of course are spammers trying to get in.
i also have another one that is about 6 months old doing about 10 a day, im guessing on that one because i don't have statistics enabled on that one yet.(statistics slows the site down, don't want to do that till i have to) im lucky if i get 1 new member a month on this one. and most of them are my friends checking it out. its depressing
