[GA4] Add a Google Analytics 4 property (to a site that already has Analytics)

Now that Google Analytics 4 has replaced Universal Analytics (UA), if you have an existing GA4 property migrated from a UA property, GA4 will still collect data, but you won’t have access to any current or historical UA data.

You can create additional properties to an existing GA4 account. It’s up to you to manage the relationships between your accounts and properties, but each GA4 account can contain up to 2,000 properties. Learn more about the Google Analytics hierarchy.

Create a GA4 property

Before you begin, make sure you are in the correct account where you want to add a new property. You must also be an Editor or above at the account level.

To create a property:

  1. In Admin, click Create, then select Property.
  2. Enter a name for the property (e.g. "My Business, Inc website") and select the reporting time zone and currency. If a visitor comes to your website on a Tuesday in their time zone, but it's Monday in your time zone, the visit is recorded as having occurred on Monday.
    • If you choose a time zone that honors Daylight Savings Time, Analytics automatically adjusts for time changes. Use Greenwich Mean Time if you don't want to adjust for Daylight Savings Time.
    • Changing the time zone only affects data going forward. If you change the time zone for an existing property, you may see a flat spot or a spike in your data, caused by the time shift forwards or backwards, respectively. Report data may refer to the old time zone for a short period after you update your settings, until Analytics servers have processed the change.
    • We recommend that you change the time zone for a property no more than once per day so Analytics can process the change.
  3. Click Next. Select your industry category and business size.
  4. Click Next. Select how you intend to use Google Analytics.
    • Google Analytics tailors the set of default reports based on the information you provide about how you intend to use Analytics. For example, if you choose "Leads," you will see a collection of reports to help you measure lead generation. Learn more about Business objectives collection.
  5. Click Create.
  6. If you want to start collecting data, you can continue to Add a data stream.

Set up data collection for websites

After adding a web stream, you’ll be prompted to set up a Google tag. You’ll have different options to select from, depending on how the site is configured. Click Show more options to see the full list of options.

Finish setting up your new GA4 property

To ensure that your new property is fully set up, in Admin, click Setup Assistant on the left side of the screen. Setup Assistant in Google Analytics 4 properties guides you through recommended features and settings to help you finish setting up your GA4 property. Learn how to Configure your GA4 property using Setup Assistant.

In Setup Assistant, you can configure:

  • Data collection
  • Property settings
  • Google Ads
  • (Optional) Advanced setup
    • Manage users
    • Import data
    • Link to BigQuery
    • Set up user IDs
    • Use measurement protocol

It can take up to 30 minutes for data to begin appearing in your new GA4 property.

To verify that data is being collected, browse your website, then select Realtime from the report navigation. You should see activity in the Realtime report.

If you have an existing Firebase project, you can link this GA4 property to it. However, you have to do this from Firebase. Learn how.
