Why do I see fewer customers with event banner.action = "show" than customers with ab test events for the same variant?
The event banner.action = "show" is usually tracked only once the weblayer is fully displayed. If the page is reloaded before the weblayer is displayed, no banner event is tracked.
The event ab test is tracked when customers are first assigned to some variant, regardless of what is displayed on the web page.
For this reason, you can sometimes see fewer customer profiles with at least one 'banner show' variant than customer profiles with an ab test event of the same variant. The longer it takes for the weblayer to display from the trigger action, the higher the chance for the user to reload the page and, therefore, not track the banner show event.
Thus, we recommend keeping an eye on the weblayer variant setting Show After or the total time it takes to render your weblayer.
