Problem Getting UserID into GA

Hi

 

I have a website with user sign-in and I'm trying to send the User ID data into GA but not being successful.

 

I have set up GTM as shown

And user ID tracking is enabled in GA

Our user ID is coming through in the datalayer as seen below

But nothing appear to be being sent through to GA (and the reports in the new view I have set up are empty. ). Any ideas/suggestions?

 Could it be a timing issue if the userId variable is not defined at the time that the tag fires?

 

Thanks

Hi Jonathan,

When you're implementing userId with dataLayer you need to make sure that dataLayer is defined before any UA tag fires. Usually it's done by hardcoding JavaScript assigning UserID before GTM snippet. Otherwise when your UA tag fires it has no data for "&uid" variable in dataLayer to send to UA so that variable resolves to "undefined" as it seem to be the case in your particular situation.

Here is a great guide from Simo Ahava about using dataLayer in GTM particularly for userID functionality: http://www.simoahava.com/analytics/data-layer/

Particulary this code from above article you may find useful:

<script>
window.dataLayer = window.dataLayer || [];
dataLayer.push({
'userId' : 'abf5-3245-ffd1-23ed'
});
</script>
<!-- GTM Container Snippet Code Here -->

Also if above is not the case a few follow-up questions/suggestions:

1. Did you enable custom dimension in GA that is specified in UA firing tag? Is it hit level? Is it at the same index number as you have it in tag?

2. Do you check your data in User-ID view or regular view? Is User ID view enabled? Does your custom dimension show any data when applied to any standard report in your regular view?

3. Google strictly recommends that field containg userID should be named "&uid" in Fields to set part of UA Tags in GTM. Did you try doing that? Source: https://support.google.com/tagmanager/answer/4565987
