Google Optimize reporting showing "no data collected" despite thousands of experiment impressions

91 Views Asked by At

Google Optimize reporting shows thousands of experiment impressions, but claims no data was collected from Google Analytics (screenshot).

Is this potentially related to the GA4 - Google Optimize outage on the 2nd? Anyone else having this issue?

I reviewed optimize settings and GA4 information. Have not set up custom dimensions within GA4.

Thanks!

It could very well be the custom dimensions requirement in GA4, but something to look at would be do you have a situation where there is 0 traffic assigned to the control? I have experienced tests where I have two variants and a control and send 0 to the control, this results in some issues with GO data.
