The session time for a website visitor is 0 if he does not click a new page.
I find most of my data in GA is 0 and I want to make the session time more accurate. I know GTM timer trigger can record the time if I set 30 seconds, 90 seconds or 5 minutes. That means I need to set several timer trigger for my blog page. Does this is the best way or you guys have better suggestion. Thanks.
