Google Analytics 4 (GA4) Setup

This guide helps you add Google Analytics 4 to an AllinCMS site: create or find a GA4 web data stream, copy the G- measurement ID, and paste it into AllinCMS admin.

GA4 is Google's website analytics tool. After setup, you can see whether visitors are opening the site, where they come from, and which pages they view.

Remember this first

AllinCMS admin only needs the G- measurement ID, such as G-XXXXXXXXXX. Do not paste the full code block or any <script> tag.

Before You Start

Prepare these items first:

What you need	Why you need it
Google account	To sign in to Google Analytics
Website domain	To create a web data stream, such as www.example.com
AllinCMS admin access	To add the GA4 measurement ID to the website

Sign in to Google Analytics first. Google Analytics setup pages are visible only after signing in with a Google account. If Google asks you to log in, sign in first, then come back and continue.

1. Open Google Analytics

Open Google Analytics.

If this is your first time using GA4, click Start measuring. If your company already has GA4, enter the existing account instead.

If you have used GA4 before, you can also open Admin from the bottom-left corner, then create a new account or property from there.

If GA4 already exists

Do not create another property if your team already has GA4. Open Admin -> Data streams and find the stream for this website.

2. Create an Account and Property

If you do not have GA4 yet, create an account and a property first.

1. Click Start measuring in Google Analytics.
2. Enter an Account name; use the company name or a name you can recognize later.
3. Keep the account data sharing settings as default, then click Next.

4. Enter the Property name; use the website name or domain, such as www.example.com.
5. Choose the reporting time zone, such as your local business time zone.
6. Choose currency; many export websites use USD, but you can choose based on your business.

7. Follow the page prompts to choose industry and business size, then click Create.

8. When the terms dialog appears, choose your region, check the agreement boxes, and click I accept.

The terms dialog may need scrolling

If you only see one agreement checkbox, scroll down inside the dialog. The second checkbox sometimes appears lower in the dialog.

3. Create a Web Data Stream

After creating the property, Google Analytics asks how you want to collect data. Choose Web.

Choose Web for websites

For website analytics, choose Web. Do not choose iOS or Android.

When filling the web data stream, focus on these fields:

Field	How to fill it
Website URL	Keep https:// in the selector and enter only the domain
Domain format	Use www.example.com; do not add another https:// or a trailing /
Stream name	Keep the default or use the website name
Enhanced measurement	Keep it enabled

After filling the fields, click Create & continue.

4. Open Data Stream Details

If you already have GA4, or you just created the web data stream, you can find it again from Admin.

Open Admin in the bottom-left corner. Under Data collection and modification, click Data streams.

Inside Data streams, switch to Web, then click the data stream row for this website.

5. Copy the G- Measurement ID

In the web stream details page, find Measurement ID.

It usually looks like this:

G-XXXXXXXXXX

Copy only this ID

Only copy the G- ID. Do not copy the full Google installation code, and do not copy any <script> tag.

If GA4 opens Installation instructions after creating the stream, do not copy the gtag.js code. Return to the stream details and copy Measurement ID instead.

6. Add Google Tag ID in AllinCMS Admin

Open AllinCMS admin for your site, then click Google Tracking in the left sidebar.

Paste the G-XXXXXXXXXX value into Google Tag ID, then click Add Google Tag ID.

7. Check Realtime Reports

After adding the Google Tag ID, open your frontend site in another browser, an incognito window, or a phone, and visit one or two pages.

If GA4 still shows the installation instructions page, you can click Test installation in the top-right corner. This is only an auxiliary check. The final check should still be whether traffic appears in Realtime reports.

Then return to Google Analytics and open Reports -> Realtime overview. Check Users in last 30 minutes.

When the realtime user count shows 1 or more, the website has started sending visit data to GA4.

Wait briefly if nothing appears

Realtime reports are usually quick, but not always instant. Wait 1 to 5 minutes, then refresh.

Common Issues

Issue	Cause	Fix
No data in GA4	The ID was just added, or no frontend page has been visited yet	Open one or two frontend pages, then wait 1 to 5 minutes
The ID does not work	Full script or wrong ID was pasted	Paste only the G- ID
The ID starts with UA-	This is the old Universal Analytics format	Create or find a GA4 G- measurement ID
Website URL cannot be saved	https:// was entered twice, or the domain ends with /	Keep the https:// selector and enter only the domain
Your own visit does not show	Browser extensions, network delay, or cache	Try another browser, incognito window, or phone
Company network visits do not show	GA4 may filter office IP traffic	Test with mobile data or check GA4 filters
The site has multiple domains	The same site may be reachable from multiple domains	Test with the official primary domain first

Pitfalls

• Do not paste <script> code; paste only the G- ID.
• Do not use the old UA- ID. GA4 measurement IDs start with G-.
• When creating the data stream, enter only the domain in the URL input.
• After adding the ID, open the real frontend site for testing.
• Standard GA4 reports can be delayed. Check Realtime overview first.
