• How it works
• Create a GA4 property
• Finish setting up your new GA4 property

Create a GA4 property

To use the GA4 Setup Assistant, you need the Editor or Administrator role for the account. You can use the tool regardless of whether your website pages have a Google Analytics tag (gtag.js or analytics.js), a Google Ads tag (gtag.js), or a Google Tag Manager container.

1. In Google Analytics, click Admin (lower left).
2. In the Account column, make sure that your desired account is selected. (If you only have one Google Analytics account, it's already selected.)
3. In the Property column, select the UA property that currently collects data for your website.
   
4. In the Property column, click GA4 Setup Assistant. It's the first option in the Property column.

   Don't see GA4 Setup Assistant? If you only see a grayed out Property Settings in the Property column, you have permissions in the View but not in the property or account. You need the Editor or Administrator role for the account to use the tool.

5. Choose how you want to migrate your Universal Analytics property. Note that the available options may vary:
   • I want to create a new Google Analytics 4 property:
     Migrate your basic settings, which includes migrating your tags, Google signals activation, and remarketing settings. This option does not migrate goals, audiences, links, and bidding in Google Ads.

     To use this option, click Get Started. (Skip to step 6.)
     

   • I want a new Google Analytics 4 property set up for me aligned as much as possible with this property's settings:
     Migrate your basic settings, plus additional configurations, which includegoals, audiences, links, and bidding in Google Ads. This option follows the same process as automatically created GA4 properties. Learn how it works

     Note: If your Universal Analytics property doesn't have any views, this option is unavailable.

     To use this option, click Create and configure a new property. On the Create a new Google Analytics 4 property page, you have the option to check Enable data collection using existing tags to include your existing tags in the migration. Then, click Create property.

     Note: The full migration takes up to five business days to complete. We send email notifications to inform users of new GA4 property creation.

6. (If you chose I want to create a new Google Analytics 4 property in step 5) On the Create a new Google Analytics 4 property page, you'll have one of the following options, depending on how your site is currently tagged:
   • Create and continue. Choose this option to continue to the Set up a Google tag page (step 7).
   • Create property. If you see this option, this means that Analytics can reuse your existing Universal Analytics tagging for your GA4 property. Analytics will create a connected site tag between your Universal Analytics and GA4 properties. Select this option and skip to the Next steps with your new GA4 property section (below).

     Note for advanced users: This option implements standard data collection for your GA4 property. If you've implemented any custom tags for your UA property, review these considerations for additional steps.

7. (If you chose Create and continue in step 6) On the Set up a Google tag page, install the Google tag manually (the first option below) or select the option that best describes your situation and follow the instructions to finish creating your new GA4 property.

   You will see some of the following options, depending on how the site is configured.
   

   Install manually

   Choose this option if one of the following is true:

   • Your website builder/CMS does not yet support the Google tag (gtag.js)
   • You or your web developer are manually tagging your website
   • Your website is tagged with analytics.js
   • You use Google Tag Manager

   How to manually install the Google tag

   When you select "Install manually," you will see the JavaScript snippet for the Google tag.

   To establish a connection between your website and Google Analytics, copy and paste the entire Google tag in the code of every page of your website, immediately after the <head> element. Don’t add more than one Google tag to each page.

   Your Google tag is the entire section of code that appears, beginning with:

   <!-- Google tag (gtag.js) -->

   If your website is tagged with analytics.js, either manually or with a CMS

   If your website is manually tagged with analytics.js, don't remove the old analytics.js tag when you add the Google tag (above). The analytics.js tag will continue to collect data for your UA property. The Google tag (gtag.js) that you're adding will collect data for your new GA4 property.

   If you're using a website builder/CMS that tags your pages with analytics.js, you can use the custom HTML feature to add the Google tag to your pages. Leave the analytics.js tag in place so that Analytics still sends data to your UA property.

   The following table lists website builders and CMSs that use analytics.js and require that you add your Google tag as custom HTML in order to have both tags on your site.

   Copy and paste your Google tag to your website using your CMS's custom HTML feature.

   Use the Realtime report to verify that you're receiving data.

Click See your GA4 property to open Setup Assistant in your new GA4 property. Setup Assistant in Google Analytics 4 properties guides you through recommended features and settings to help you finish setting up your GA4 property.

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.
