Same web property ID is tracked twice error

Visitor ✭ ✭ ✭

Dear community

 

I use Google Tag Manager on my website (www.radiologycafe.com) and when I active the Google Tag Assistant Chrome plugin I get the following error associated with my Google Analytics tag:

 

'Same web property ID is tracked twice'

 

What does this mean and how do I fix it?  I only use one GTM account on my site.

Hi,

 

No problem, I'm sure that I don't understand your question. I don't understand why the data outside the custom dimension would not be sent to GA. Basically the GA tracking tag collects the information from the website and sends it using a GET request to the GA servers. The request looks something like this:

https://www.google-analytics.com/collect?v=1&_v=j56d&a=1332405713&t=pageview&_s=1&dl=https%3A%2F%2Fw...

 

Now when you add a custom dimension to the tag, the GET request will have additional query parameters containing the data for the custom dimension(s):

 

https://www.google-analytics.com/collect?v=1&_v=j56d&a=1332405713&t=pageview&_s=1&dl=https%3A%2F%2Fw...&cd1=dimension-data

 

So if you create a second tag, you will end up sending all the data twice, that's why Tag Assistant reports that the same property is tracked twice. You will have each page view tracked twice that will mess up your data. Let me know if you have more questions, I'm happy to help.

Hi,

 

Please check in GTM, it seems that you have two Google Analytics tracking tags for the same property.

Hi Arnold, thanks. I've checked and I have two Universal analytics tags, both firing on all pages.  One is all analytics, and I created the other to track logged-in (signed in) users on my website by adding a field and custom dimension.

 

How do I correct this so there is no overlap?

Hi,

 

Leave only the tag that tracks the custom dimension and create a new view that includes only traffic that has the custom dimension set.

You can also create a User ID view for logged in users, it enables you to track them across devices:

Hope this helps, let me know if you have questions.

Thank you. I've already got a user-id view which works well in analytics.

 

However, not only do I want to track the custom dimension (user-id), I also want to track all other visitors to my site as well.

 

Only a small number log in so I don't want to exclude the other users.  Ideally I want a view which shows all users (guest + logged in) called Raw data, and then another view with just the logged in users segmented out (user-id view). For example, if in one day there are 100 sessions, 20 of which have users logging in, I want one view looking at all 100, and another looking at just the 20 logged in).

 

After searching everywhere I can't find how to do this using just one tag.  Do you know how?

Hi Christopher,

 

As I mentioned above, you can set up a view for logged in users and include only traffic that has the user id-set, your filter would look like this:

Let me know if this helped to achieve what you wanted.

I'm sorry, but I don't think you understand my question, or maybe I've not explained it clearly.  It's a bit difficult to explain. I'm worried that if I add a dimension to a tag in GTM, that all data outside of that dimension will not be sent to analytics.  How do I get around this without creating a second tag without a dimension?

Thank you Arnold! That explains it perfectly. I couldn't find this information anywhere. Google should add it to their help pages as it's pretty fundamental to understanding how it all works (to a beginner like me!).

 

You have been a star. Thanks again!
