My website is largely targeted to US business users. Not surprisingly, the number of visits during the weekdays is much larger than on Saturdays and Sundays. In addition, on holidays like July 4 or Christmas, the number of visitors drop dramatically. I also have a feeling that internet usage decreases slightly in summer months while people are on vacation/outside. The result is that in Google Analytics (pic below), my daily visitors go up and down and appears relatively erratic. It's hard to determine if any increase or drop in visits is attributable to something on my site or is part of a trend across the US.
Is there a way to normalize the number of visitors to my site against internet usage in general? Or are there tools other than Google Analytics that do this?
If normalized, the chart below would look much flatter and if there was an increase, I would know it would be attributed to something on my site rather than to the internet in general.
