Hi Guys, does anybody have experience setting up reporting of GrowthBook experiments in GA4? We've set up custom dimensions in GA4 to retrieve the properties send by GrowthBook, through Rudderstack. The event
viewed_experiment
and properties (
experiment_id
and
variation_id
) seem to come through in the default event report, but within a custom report (explore) it only returns
(not set)
values. Does anybody know how to get the values in a GA4 report, so you can analyse on various metrics and compare Control and Variation?

If you're using custom dimensions, you need to set it to be at the user level, not hit level, so it persists beyond the initial event. GrowthBook can actually query your GA data and do all of the statistical analysis for you, which makes everything much easier. We just require you to send your events to a data warehouse like BigQuery, which is easy to configure with Rudderstack.

Thank you Jeremy, as you can see in het screenshots, only the dimension of the
viewed_experiment
parent-event is set at event scope. The 2 dimensions, which are properties of that same event, are set at the user scope. Could this be the problem? We are using GA to check for differences and to be able to do more in depth analyses since there are more filtering/segmentation options.
Still haven't figured out why I'm getting the
(not set)
values within my reports on
variation_id
and
experiment_id
, while the custom dimensions are set at the user level and the properties are returned in at the event report (30 minute report). Any help appreciated 🙏

Don't know how much I can help there. I think that's more a question for Google Analytics. If you're able to get the data into a BigQuery data warehouse, I can help you get metrics and experiment results showing up within the GrowthBook app.

Thank you Jeremy. I think you're right and it's not directly related to GrowthBook, since we're able to get that data right into the application. I'll post the issue elsewhere on a suitable forum.
