DTM Event Based Rule Firing Twice
I am tagging a microsite which is built on one page. I want s.tl calls to fire once each section of the page appears in the viewport for 2 seconds. When I use Event Type 'enters viewport' and select the radio button 'for ____ milliseconds [and use 2000 in the blank], the Adobe Analytics call fires twice.
If I change this to the immediately radio button it fires only once, but it does not get me the metric that I am interested in because it does not tell me if a person has actually stopped on a given section to look at it or just scrolled quickly past it.
Thanks!
