Step-by-Step Instructions

Access Google Analytics Admin

Log into your Google Analytics account and click the Admin gear icon in the bottom left corner of the interface. This will open the administration panel where you can manage your account and property settings.

Make sure you're viewing the correct account if you have multiple Google Analytics accounts

Select your Property

In the middle column labeled Property, ensure you have selected the correct GA4 property from the dropdown menu. If you need to switch properties, click on the property name and select the desired one from the list.

Navigate to Data Streams

Under the Property column, locate and click on Data Streams. This section shows all the data streams configured for your property, including web, iOS, and Android streams.

Data Streams replaced the old tracking code setup from Universal Analytics

Select your Web Data Stream

Find your website's data stream in the list and click on it. The stream will typically show your website URL and be labeled as Web in the platform column.

If you have multiple streams, look for the one matching your website's domain

Locate the Measurement ID

On the data stream details page, you'll see the Measurement ID in the top right corner of the stream details card. The ID will be in the format G-XXXXXXXXXX where X represents alphanumeric characters.

Copy the Measurement ID

Click the copy icon next to the Measurement ID to copy it to your clipboard. Alternatively, you can manually select the entire ID text and use Ctrl+C (Windows) or Cmd+C (Mac) to copy it.

Double-check that you've copied the complete ID including the 'G-' prefix

Verify the copied ID

Paste the copied Measurement ID into a text editor or your destination application to verify it was copied correctly. The ID should start with G- followed by 10 alphanumeric characters.

Save the ID in a secure location for future reference if you'll need it again

Common Issues & Troubleshooting

Cannot see Admin option in the interface

Ensure you have the necessary permissions for the Google Analytics account. Contact your account administrator to grant you Editor or Administrator access to the property.

Data Streams section is empty or missing

Verify you're working with a GA4 property, not Universal Analytics. If using GA4 and streams are missing, you may need to set up a new data stream for your website first.

Measurement ID shows as 'UA-' instead of 'G-'

You're looking at a Universal Analytics property. Switch to your GA4 property in the property selector dropdown, or create a new GA4 property if you haven't migrated yet.

Copy button is not working

Try manually selecting the Measurement ID text and using keyboard shortcuts Ctrl+C or Cmd+C. Also check if your browser is blocking clipboard access and allow it when prompted.
