Hey, I'm a first-time user and just set up my first A/B test, which is currently live. However, I’ve noticed that no data is being tracked yet. I’ve followed the GA4 implementation instructions provided in the docs. Is there typically a delay before metrics start appearing? If so, how long should I expect to see results?
f
Are you using gtm?
t
Hey @fresh-football-47124 yes we are
Following up, we do use a combination of GTM + big query for GA4 data imports
f
so custom events are intercepted by GTM
you need to add the custom event to GTM to allow it to be passed to GA4 and BigQuery
t
Thanks, I am still a bit confused - I have already installed this snippet in our Webflow header as per the instructions in this document. Have also followed the steps in this A/B Testing with Google Analytics 4 (GA4) and GrowthBook document. The metric I am measuring against is available to be used - won't that be sufficient now? FYI the metric is an event in GA4
Hey @fresh-football-47124 double checking if my above logic is correct
f
There is a second step for GTM
Did you follow that?
t
No I have not. Do I simply need to follow step 4 in the guide?
f
Yes- though Google changed some of the steps in terms of the UI
But it’s mostly the same
t
Thanks will give it a go
Hi there, I’ve followed all the steps outlined in the GrowthBook guide and used the Webflow SDK connection’s client key to sync with GTM. However, the tag isn’t being triggered. Double-checked the unfired tag and here’s no experiment ID or variation ID being passed through. Could you help me troubleshoot what might be going wrong? Have followed your document and this

you should be able to see a experiment_viewed in the window.dataLayer

Hey @fresh-football-47124 - I'm Marco's coworker and just jumping in here. So the steps we've taken so far are: 1. So we've put the snippet on Webflow 2. Added Growthbook SDK via custom HTML tag in GTM (which is firing) 3. Setup the data layer variables 4. Setup the trigger + tag What we're seeing in GTM preview 1. The Growthbook SDK tag is firing 2. 
experiment_viewed
event does not seem to be firing (and thus the data layer variables are not updating) I've worked through the checklist below: Let me know what the best next steps are? I could record a loom of our setup and DM that through for clarity if helpful?
t
Hey @fresh-football-47124 following up the checklist above^
f
If you see the experiment_viewed event in the datalayer, but don't see it in GA or BigQuery
it is 99.9% of the time caused by GTM blocking it or not being set up correctly
g
We're not seeing the experiment_viewed event in the data layer. "Growthbooks SDK" was setup according to: (and it's showing as connected via the SDK connection): @fresh-football-47124 https://docs.growthbook.io/guide/google-tag-manager-and-growthbook#2-create-gtm-tag-for-growthbook
Hey @fresh-football-47124 just following up on the above and appreciate your patience helping us work through this!
