if Google analytics return the wrong result? avg.visit duration 00:00:00,and many more these questions.
I do not understand you questions. But if you are saying that Analytics says that your visitors have 00.00.00 avg time on site then: - you dont have traffic at all - You analitics scrips is dameged ( reinstal the script on your site ) - the traffic you get is small or not targeted at all, and visitors dont stay on your site Hope it helps!
