Google Tag Manager and multiple domains. How many containers do you need?

[@BarbaraAlvarezSolanilla]

Very useful video! I went through a bit project splitting GTM setups into different containers to isolate them by websites. The chaos on the main GTM container with tracking for more than 5 websites with different structures, tracking and formats was a challenge! And since consent mechanism has been added to GTM implementations I do recommend having a single GTM container for each website, unless the websites are very very similar!

[@mennobouma]

Great video Julius! I have a website with 7 languages / domains and my experience is that it quickly becomes confusing to put everything in 1 container. That is why I have chosen a separate container for each language.

You are GAWD in Analytics

[@agunslinger9349]

Love the material! To be clear, if one GTM container is used for several websites, the same GTM install script code goes in the on all the sites, correct? And the Lookup Table variable for the different GA4 properties manages the incoming data.

[@AnalyticsMania]

Yes

[@terryhelliker118]

I have multiple websites currently running with their own Analytics and Tag Manger accounts. Now I want a Rollup account so I can track all the websites in one account (there’s many reasons why I need this), but I question what the best setup is. Shouid I just implement a second Tag Manger code on all my sites or ??? Any suggestions or help would be greatly appreciated. (Thanks)

[@AnalyticsMania]

You don't need to create a separate GTM container. Both properties can be in the same container. But there is some additional configuration needed in the rollup property. I explain that in my GA4 course www.analyticsmania.com/courses/google-analytics-4-course/

Great info. Thanks for sharing

Thank you for sharing your knowledge. Very good content.

[@CantonicaTech]

When you wrote property in the lookup table output it is the measurement id correct or it is the property id associated with the measurement id? my property id does not start with G

[@AnalyticsMania]

Measurement id

Thank you! I am also thinking that managing Consent Mode stuff using multiple Containers could be easier in comparison to a single Container for multiple websites

Thanks for sharing your knowledge. Very useful video. 👏

Hai, what do you think if my business is generating lead from 1 domain, and doing conversion in other one, what should i do to make sure that the 1 user from both web count as 1 user.

[@GonzaloGóngora-z9s]

Hi Julius, i have the same GTM container in the main domain and 3 subdomains. For tracking some form leads in the main domain, the trigger is a TY page in a subdomain (in not my decision), so i have the problem that i lost all the variables like "email" (DOM type, for user provided data), only the "hostname" in the referrer (but don`t the page path), etc. Because all this kind of variables are "undefined" in the new subdomain TY page. How could i fix it? Thanks in advance!!

[@wingho2868]

Thank for sharing. But I cannot find the tag type of "Google Analytics: GA4 Configuration", what should I do?

[@AnalyticsMania]

Use the tag called "google tag" instead

I have 2 websites but I want to focus on only one. Should I create one container for that one blog and how can I use it to track woocomerce. And do I create a different container for Pinterest and Facebook?

[@kenzabadiri9820]

Thank you for the video ! Very helpful :) @AnalyticsMania When using the same GTM Container to configure event tags for "Google Analytics: GA4 Events" which ID should be used for measurement? Should it be the Measurement ID of the specific GA4 property where the event will be published, or should we use the look-up table variable created for this purpose? Furthermore, if the Measurement ID of the target property is used, how can we guarantee that the event gets published in both properties ?

[@AsimKhan-fx7rs]

I am using one GTM for multiple domains and now things become complicated like data discrepancy. Tags fire correctly but do not reflect the total number of conversions on Google ads, but reflect on an analytics tool. Any suggestions? Why, the values are not reflected in google ads?

[@ahudsonchampionmgt]

Hi there! I have two separate containers for similar websites to ensure that there is no contaminated data. With this, I would like to use both containers on one google ads page but I am not offered the option within my google ads account. Is this possible and if so, how would I add this container into the google ads account?

[@ReluctantApostate]

I'm using one container for my primary domain and one for a subdomain. They're both using the same GA4 measurement ID. How do I restrict the container to only fire events and evaluate triggers on its own domain?

[@AnalyticsMania]

By adding a condition "page hostname contains xxxx" condition in triggers

[@ReluctantApostate]

@@AnalyticsMania Oh. So if I understand you right it means every trigger I set up in these containers needs to have this added. This sounds cumbersome. Is there no global container-wide setting to apply to each? i'm struggling with how to setup my analytics for my site and store given that GA4 automatically includes subdomain, but that each subdomain has different events to track

[@nadjanahuz1229]

@@ReluctantApostate I have the same problem here. Have you had any luck solving this?

[@ReluctantApostate]

@@nadjanahuz1229 well i've decided to just keep my containers separate and try to add in the corresponding hostname paramrter for every trigger like was suggested. It's not ideal, but at least i don't have too many to setup at this point. Sure would be nice to have some global settings in the container though.

[@ReluctantApostate]

@@nadjanahuz1229 actually I think I missed an important detail and this isn't even necessary. I have one account that has two containers. One container is for my main site, the other is for a subdomain. Because I'm only loading the container associated with the domain / subdomain I won't have any crossover of triggers. They're already split. Adding a hostname would only be necessary if I had my domain and subdomains using the same container. I think I got confused because they're both using the same measurement ID so I thought they would be loading the same triggers and events through that. But that isn't true

[@dukevillanueva375]

Good video!

[@awababd-arrahman3104]

Hi Julius, is it possible for developers to not use GTM and make custom events that fire in GA4?

[@AnalyticsMania]

Yes, use GTAG
