Re: Analytics unique visitors
It's the difference between unique for a day vs unique for a month - if you went unique for a year the total would be even lower.
The reason (and this is a good thing) the daily totals are higher than the monthly is because of "repeat" visitors. They aren't unique for the month when they come back multiple times, but they most certainly are unique per day each day they come back - so for instance if 10 visitors visit your site every day for the month they are only 10 unique visits but the daily sum is actually 300 for a 30 day month - make sense?
