You need Edit permission on the account to add properties. To set up a property:

1. Sign in to Google Analytics..
2. Click Admin.
3. In the ACCOUNT column, use the menu to select the account to which you want to add the property.
   If you have a lot of accounts, use the search box to help you find the right one.
4. In the PROPERTY column, select Create new property from the menu.
   If you don't have Edit permission on the account, you won't see the Create new property option. Check that you've selected the correct account in the ACCOUNT column.
5. Select Website or Mobile app.
   If you select Website, skip to Step 7.
   If you select Mobile app, continue to Step 6.
6. (Mobile app) Under Tracking Method, select Firebase. Select an app from the menu and click Connect App.
7. Enter the Website or App Name.
   If you plan on tracking more than one app in your account, use a very specific and descriptive name that includes the edition or version number. This will help you keep your app properties organized.
8. (Web only) Enter the Web Site URL.
   You cannot create a property if your URL isn’t formatted correctly.

   See how to correctly format your domain name.

   Select the protocol standard (http:// or https://). Enter the domain name, without any characters following the name, including a trailing slash (www.example.com, not www.example.com/).

   Most domain hosts only support UTF-8 characters in the URL. It's a good idea to use either UTF-8 characters or punycode for symbols and any non-UTF-8 characters (including Cyrillic characters) in your domain name. Try a punycode converter for help with this.

9. Select an Industry Category.
   When you select an industry category, you can use goal templates designed for your industry.
10. Select the Reporting Time Zone.
    This will be used as the day boundary for your reports, regardless of where the data originates.

    See more about how the Reporting Time Zone setting works.

    • The time zone setting affects how data appears in your reports. For example, if you choose United States, Pacific Time, then the beginning and end of each day is calculated based on Pacific Time, regardless of whether the sessions are detected from New York, London, or Moscow.
    • If your Analytics account is linked to a Google Ads account, the time zone is automatically set to your Google Ads preference and you will not see this option. This ensures accurate reporting on your Google Ads campaigns.
    • Changing your time zone affects data going forward, and is not applied retroactively. You may notice a flat spot or a spike in your report data around if you update your time setting after you’ve already been using this property. Your reports might also refer to the old time zone for a short period after you update this setting.
11. Click Get Tracking ID.
    Your property is created after you click this button, but you must set up the tracking code to collect data.
