I've been doing a ton of research on Google Analytics v4 and the biggest hurdle I have is that I cannot find how to simply report on the conversion rate for any default channel grouping (or campaign, etc.).
I've checked the Acquisition > Traffic Acquisition report, I've used the new Explorer, and I've also even tried Google Data Studio. None of these have this metric available.
GA4 report with only total conversions available:
GA4 Explorer no Conversion Rate metric in search results:
Google Analytics 4 does have a Default Channel Groupings dimension, and does report on raw conversion numbers, but does not appear to have a conversion rate metric that shows the percent of converting sessions (like Universal or Gtag has).
Universal Analytics has conversion rate metrics in many reports:
I've heard rumors that Google is still working on adding features to GA4, and while I'm trying to avoid complaining about making GA4 the default property type without essential features, I am wondering if anyone has found the conversion rate metric in any reports, and if not, what are your workarounds?
I would certainly argue that this should be able to be done without needing to jump through hoops, but at this point I would take any process to find this data in GA4. The only thing I can think of at the moment would be to do the math manually inside of Data Studio... but that is much more time consuming compared to two clicks in Universal Analytics.
I will happily update this in the future and provide my own answer if necessary once this metric is added (if it is truly missing as of now).
