My Google Analytics page shows almost twice as many Users than Sessions. It really doesn't make sense to me, does anybody know what's the reason for this?
Here is a snapshot from my GA dashboard:
For those that land on this question where they experience more users than sessions in Audience Overview (I.e. no custom report or hit level dimensions concerned, which seems to crowd out search results when researching this issue) ask this:
I learned this today. If you have events that fire on an iframe but no pageview tag on the iframe, then a new user is generated in Google Analytics on the back of that event, but no new session.
The prescribed way to get around this is to add the iframe or subdomain name to the referral exclusion list in Admin > Profile > Tracking info. However, that currently seems buggy since I had done that and not working as expected and I still saw this issue.
Regarding the 3rd point, if your visitors are landing, triggering an event and then bouncing before the pageview tag fires it may under report sessions. For example, one of our clients pageview tags, configured in Google Tag Manager, waits for the page to load before firing since we want the crm system to finish loading so we can grab some data and feed as a custom dimension into GA.
This is not actually my answer, you are getting it second hand via me from here. Read the link for more details. Posting here since I was getting frustrated finding anything on this.
