Since June 3rd (when we enabled Growthbook on our website & setup first experiment) we're seeing a huge spike in traffic on our server-side GA4 (Weirdly, it did not affect our client-side implementation.). What could be causing this and what could be a fix? Is Growthbook sending events other than experiment_viewed?
We have both website and web app. We run tests on the website, but conversions happen in-app.
• For data we send our Server-side GA4 to Big Query and then to Growthbook.
• We tried to implement Growthbook everywhere using GTM. However, experiment_viewed event wasn't working with this implementation.
• We found a solution: on the website, Growthbook snipped is hardcoded, while on the web app it's installed through GTM.
• experiment_viewed event is implemented through GTM and it's sent to both Server-side and Client-side GA4.
• We were able to run tests successfully and conversion data is coming in - all seemed fine.

We don't send other events

and on server side, we don't send anything other than what you define on the trackingCallback

for the HTML snippet we do the experiment_viewed event automatically -but you can override that if you want

06/20/2024, 9:15 AM@fresh-football-47124 when exactly does the experiment_viewed event trigger? It might help us get to the cause of the issue.

06/20/2024, 9:18 AMDo I understand well, i looked into trackingCallback and it seems to be only needed in custom implementations?
if we have the standard snippet + GA4 event installed via GTM we don't need to do anything? I can't find the right docs.

We fire one event when a user sees an experiment
fresh-football-47124
06/27/2024, 6:21 AM
which is fired from the trackingCallback, and fires an event called 'experiment_viewed'

if you're adding the HTML SDK, we fire that event automatically, but you can override it
