Google Analytics 4 Sub Properties Tutorial

Last Updated: November 15, 2022

What is a sub property in Google Analytics 4 (GA4)?

A sub property is like a typical GA4 property, but it gets its data from another property (also called the source property).

In other words, a sub property inherits its data from the source property. The inheritance takes place by inheriting the data streams of the source property.

The inherited data is often filtered. As a result, the data in a sub property is often the subset of the data in its source property.

What type of data a Google Analytics 4 sub property can inherit?

A GA4 sub property can inherit the following types of data from its source property:

#1 All or subset of the event data from the source property.

#2 All data from source-property product integrations. 

So if the source property is connected to your Google Search Console and Google Ads accounts, then the sub property can inherit all of this data without being directly linked to either your Google Search Console or Google Ads accounts.

When to create a sub property

Create a sub property when: 

#1 You want to create a filtered reporting view in GA4.

#2 You want to give a user access to only the subset of data in the source property.

For example, suppose your target market is the US, Canada, and the UK. 

You can then create one GA4 property which collects data from the US, Canada and UK. 

Then create one sub property for each of your target markets. 

So you can have one sub property for the US market, one sub property for the Canadian market and one sub property for the UK market.

Once you have sub properties in place, you can then give access to different markets to different users. 

Note: A source property can have one or more sub properties.

How to work with a sub property

You work with a sub property the same way you would work with any GA4 property. 

For example: 

Note: The events processed by a sub property are called sub property events. The events processed by a source property are called source property events.

Limitations of a sub property

The following are the limitations of a sub-property:

#1 Only a GA4 360 property can be used as a source property for a sub property. Consequently, you can use the GA4 sub properties feature only when you have access to a GA4 360 account.

#2 Currently, a sub property can not inherit custom dimensions and custom metrics from its source property. You would need to re-create them in your sub property.

#3 A sub property cannot have events of its own. It can only inherit event data from its source property. As a result, you can not create or modify events in a sub property.

#4 You can not add or delete data streams in a sub property.

#5 You can not import offline events to a sub property.

#6 Currently, a sub property can only be directly linked to Google Ads. They can not be linked to other accounts like the Google search console. 

#7 A sub property does not automatically process the Google Signals data from its source property.

You would first need to activate Google Signals in the sub property before the Google Signals data can be processed.

#8 There is an additional cost associated with creating and using sub properties. They are not free to use.

As per the terms of your 360 contract, the cost of processing the sub property events is one half of the cost of processing the source property events.

#9 You can not move a sub property from one GA account to another as the sub property relies on its source property for its data.

#10 You can not downgrade a sub property from 360 to standard as a sub property can exist only as a GA360 entity.

#11 You can not create a sub property from another sub property or a roll-up property.

Dependencies of a sub property on its source property

Following are the various ways a sub property is dependent on its source property:

#1 A sub property cannot have events of its own. It can only inherit event data from its source property. So if the source property does not have the required event data, its sub property won’t have that data either.

#2 Any data you delete from a source property is automatically deleted from its sub property. However, any data that you delete from a sub property is only deleted from that sub property.

#3 If you delete a source property (i.e. move it to the trash can), all its sub properties are also deleted. However, you can delete a sub property without affecting its source property.

#4 If you restore a source property, all its sub properties are also restored.

#5 If you remove a user from a source property, that user is also automatically removed from its sub property. However, when you remove a user from a sub property, that user is removed only from the sub property.

Dependencies of a source property on its sub properties 

#1 If you want to move a source property from one GA account to another, you would first need to delete all its sub properties (i.e. move all the sub properties to the trash can and then wait 35 days for Google to delete them permanently).

#2 If you want to downgrade a source property from 360 to Standard, you would first need to delete all of its sub properties.

Note(1): A source property and its sub property can all have independent integrations with the same product (like Google Ads). In such a case, the source property exports only its data and the sub property exports only its data.

Note(2): Google recommends that you link products (like Google Ads and Google Search Console) to the source property and not to its sub property to ensure data integrity.
