Two mysteries I hope you can explain to me:
1) What exactly does the $ Index mean?
If I have 100 visits to a page and there is a $ Index value of .22 (twenty-two cents), does that mean that those 100 people who visited the page spent an average of 22 cents each (for a total of $22)?
2) What could be the cause when the number of visits to a page goes UP 5% but the $ Index DROPS 72% (over a period of a month - when compared to the previous month)?
Thanks in advance.
