Hello, I would like to know why I am finding differences in metrics compared to other platforms, specifically GA4. Metrics on this platform show up to twice as much as on Growthbook. What could be causing this? In one specific experiment, I am using “purchase” and “ARPU” as goal metrics. (in GA4 there ismore than 6K users)

We need som more info to help debug/understand this. Where is the experiment running/configured? That is, what kind of experiment is it, what triggers it, etc.

@strong-mouse-55694 It is configured with a feature flag; these are only visual changes showing a corner treatment (promotion badge) or hiding it. No trigger is used to capture; the aim is simply to measure which is more effective, control or variant, with this small aesthetic change.

Thanks. Is that active on each of the pages you highlighted in GA?

that's right, those pages are where the promo badges are configured

And you're piping this data to Big Query?

Yes, the GA4 data is being piped to BigQuery, and GrowthBook is connected to that dataset

In BigQuery, are you able to confirm whether the numbers match or not? It can take some time, too, for the data to reach BigQuery, so that's something else to be aware of, depending on your set up.
