Also, more than 450 leads spent in excess of 5 minutes (more than 300 seconds) all the way up to 30 minutes (over 1700 seconds). Spending more than 5 to 7 minutes on the landing page would also be kind of strange.
Anyone has any take on this?
try to get your visitor to click something
(obviously analytics code should be on every page you have)
also the gigantic numbers come from people like me who carry an abverage of 5 tabs open on my computer at all times even when im not home (google assigns a max time)
