I'm trying to get an accurate measure of site bounce rates for my school's website. However, all school computers have the school's site as their homepage, meaning any time somebody opens the browser the school site is visited, regardless of whether or not the user intended to visit the site. I feel that this has skewed the bounce rate, as many people visiting the homepage never intended to do so.
I'm aware that Google Analytics allows you to track traffic sources, but I can't seem to find a way to separate direct visits (i.e. people typing in the URL to visit) from homepage visits. Is there a way to do so?
