Do Bounce Rate go down If I put two GTM Id on one domain?

[dsouzac]

Hello Experts,

By mistake by developer has put two GTM on my Main site i.e. One GTM id of Main site and one Google Analytic script of staging site ( testing site).

And on that day along with my Main site analytic same traffic visible on my staging site whole day and next day in analytic my bounce rate gone down from 57% to 45% .

So my query is do such thing really impact bounce rate? If yes then how?

Thanks!

Hi All,

Let me clear one more thing that analytic script my developer added on Master of Mobile Control only and on staging site analytic I am able to see main site traffic related to Mobile only and my bounce rate improved only for Mobile site not for desktop or tablet.

Thanks!
