Bounce Rate Dropped - Duplicate GA Calls?
I have a situation where my site saw a dramatic drop in bounce rate. I know this could be due to duplicate instances of UA codes on site, I checked and this wasn't the case.
I tried to do some debugging, but i'm still a novice here. I used the Chrome GA debugger and saw that there were multiple calls for the UA code installed on the website.
Now, at this point, i'm thinking that the UA script is running twice, which is leading to the decreased bounce rate (but, i'm not sure if my assumptions are correct).
I used another tool and saw that the 2nd UA call is listed as a 307 redirect.
Before I contact my developer to find out why the UA is being executed twice, I want to be sure that I am interpreting these dashboards correctly. Can someone review and let me know if they've experienced this before and if I am making the proper assumptions?
Thanks in advance.
Re: Bounce Rate Dropped - Duplicate GA Calls?
If you're bounce rate dropped like that there are usually only two things that happen:
1. Duplicate instances of the GATC (It's not always implemented inline and could be called from an external script) you can look at the network tab to see this, use GA debug as you have done and try Tag Assitant in the Chrome store as well.
2. A pageview occurs and then is followed by another hit (usually an event that has not been set to non-interaction) without the user doing anything.
You can use the landing pages report to see if this is across all pages or just the home page, etc.
