What will happen if you track pageview with standard ga tracking code and track events with GTM?
Recently I am analysis a website and found that it has an unrealistic low bounce rate. And I also found that they track their pageview with standard GA code while in GTM, they "didn`t fire pageview" but have a lot of event tracking.
My hypothesis is that GTM can`t tell which events correlated to which session so this might be something to do with the weird bounce rate, but I actually have no idea.
So my question is, what actually will happen if you track pageview with GA and event with GTM(without firing pageview tag)
Let me know your thought,
