How to Tell if Google Analytics 4 is Installed
Wondering if Google Analytics 4 is correctly set up on your website? You’re not alone. Whether you've just migrated from Universal Analytics or had a developer handle the setup, it's smart to double-check that your new tracking code is installed and actively collecting data. This guide will walk you through several simple methods to confirm your GA4 installation, from easy in-app checks to a couple of quick browser tricks.
The First Place to Look: Your Google Analytics Account
Before you start digging into website code, the easiest first step is to check inside your Google Analytics account itself. The user interface and property ID structure are completely different in GA4 compared to its predecessor, Universal Analytics (UA), giving you an immediate clue.
1. Check Your Property ID Format
Log in to your Google Analytics account. In the top left corner, you’ll see a dropdown menu that lists all the accounts and properties you have access to. Find the one for your website.
- A Google Analytics 4 property ID starts with "G-" followed by a string of numbers and letters (e.g., G-XYZ123ABC).
- An old Universal Analytics property ID starts with "UA-" followed by numbers (e.g., UA-12345678-1).
If you see a "G-" ID, it confirms you have a GA4 property. If you only see a "UA-" property, GA4 has likely not been set up yet for this website.
It's also possible to see both, a common scenario for sites that ran Universal Analytics for years and added a parallel GA4 property during the transition. Seeing both is perfectly fine, your main goal is to confirm the "G-" property exists and is linked to the right website.
2. Explore the Data Stream Settings
Another tell-tale sign is the presence of "Data Streams." This is a feature unique to GA4 that replaced the "Views" from Universal Analytics.
- Navigate to the Admin section by clicking the gear icon in the bottom-left corner.
- Under the Property column (make sure you've selected your supposed GA4 property), click on Data Streams.
- You should see at least one data stream listed, typically named after your website's URL. Click on it.
This screen gives you the most critical piece of information: your Measurement ID. This is your unique "G-" ID that needs to be present on your website to send data to this specific property. Take note of this ID, as you'll use it in the next few methods to make sure it's the correct one on your live site.

Inspect Your Website’s Source Code
If the GA property is set up correctly, the next step is verifying its tracking code is actually on your website pages. You can find this by looking at your site's underlying HTML source code. This might sound technical, but it’s actually a straightforward copy-and-paste check.
How to View Page Source
Go to your website. Once the page is loaded, right-click anywhere on the page and select View Page Source (this wording might vary slightly between browsers, like "Show Page Source" or similar).
A new browser tab will open showing the HTML code of your homepage. Don't be overwhelmed by the code. You just need to search for one thing.
What to Search For
Press Ctrl + F (on Windows) or Cmd + F (on Mac) to open a search bar. Now, type in the Measurement ID ("G-...") you found in your Data Stream settings.
If the ID is installed directly on your site, you should find it within a script tag that looks something like this:
<script async src="https://www.googletagmanager.com/gtag/js?id=G-YOUR_MEASUREMENT_ID"></script>
`<script> window.dataLayer = window.dataLayer || [], function gtag(){dataLayer.push(arguments),} gtag('js', new Date()),
gtag('config', 'G-YOUR_MEASUREMENT_ID'), </script>`
Finding this script with your matching "G-" Measurement ID is a very strong sign that GA4 is installed correctly. If you're using Google Tag Manager, you might not find this exact script. Instead, search for gtm.js. If you find the Google Tag Manager container, it confirms GTM is installed, and your GA4 tag is likely being fired through it, which we’ll cover in the next method.
Use Browser Developer Tools to See Live Data
The previous method confirmed the code exists on your page. This next method confirms it's actively working and sending data back to Google's servers. We’ll be using the "Developer Tools" built into every modern web browser.
Step-by-Step Instructions
- On your website, open Developer Tools by pressing F12, or right-clicking and selecting Inspect.
- In the panel that opens, find and click on the Network tab. This tab shows every single file and data request your browser makes to load and run the website.
- In the filter bar at the top of the Network panel, type
collect?v=to narrow down the hundreds of requests. This filters for Google Analytics data hits. You may need to refresh the page after typing in the filter. - Now, click around your website. Go to a new page, click a button, etc. As you do, you should see new entries populating the Network tab.
Look for requests that include collect?v=2 in the name. The v=2 indicates a GA4 hit (whereas v=1 was a UA hit). Click on one of these requests, and look at the "Headers" or "Payload" tab in the details panel. Within the "Query String Parameters", you should see a parameter named tid. The value of this tid parameter should be your GA4 Measurement ID ("G-...").
If you see these requests being sent with your correct "G-" ID, you have 100% confirmation that Google Analytics 4 is installed and actively tracking pageviews and user activity.
Use a Browser Extension for a Fast Check
By far the fastest and easiest way to check for marketing tags is to use a free browser extension. These tools scan the webpage you’re on and provide a clean report of all tracking technologies they find.
Google Tag Assistant
The best tool for the job is Google's own Tag Assistant Companion. It's an official Chrome extension designed specifically for debugging Google tags (GA4, Google Ads, Tag Manager, etc.).
- Install the extension from the Chrome Web Store.
- Navigate to your website and click the Tag Assistant icon in your browser's toolbar.
- A small window will prompt you to connect. Click through the steps to open a debug window for your site.
- As the debug window loads your site, the Tag Assistant will show you every Google tag found on the page.
You should see a "Google Analytics GA4" section with your Measurement ID listed below it. You may also see a "Global site tag (gtag.js)" tag, which is the underlying script. If your G- ID appears here, you are good to go. The extension will also color-code the tags to let you know if they are working properly (blue or green) or have errors (yellow or red).

Other Useful Extensions
- Wappalyzer: A popular, general-purpose technology profiler. It doesn't just find Google Analytics, it identifies your CMS (like WordPress or Shopify), your web server, JavaScript frameworks, and more. It's a great tool for a quick overview and will show "Google Analytics 4" in its list if detected.
- Dataslayer: This extension is more developer-focused but incredibly powerful for anyone using Google Tag Manager. It shows the real-time data layer information passing through GTM, so you can see not only that your GA4 tag fired, but exactly what data it sent.
Checking Your Platform or CMS Settings
Many business owners and marketers don't install analytics code by hand. Instead, they use built-in integrations in platforms like WordPress, Shopify, or Squarespace.
On WordPress
If your website runs on WordPress, you most likely installed Google Analytics via a plugin.
- Google Site Kit: This is Google's official plugin for WordPress users. Go to the Site Kit dashboard in your WP-Admin, click Settings > Connected Services > Analytics. There, it will show you exactly which Account, Property, and Measurement ID are linked.
- Other Analytics Plugins: If you use a different plugin (like MonsterInsights, GA Google Analytics, etc.), navigate to that plugin’s settings page. It will have a dedicated field where the GA Tracking ID was pasted in. Confirm that the ID in that field is your new "G-" Measurement ID.
On Shopify
For Shopify stores, Google Analytics integration is typically handled through the Google & YouTube channel app.
- In your Shopify Admin, go to Sales channels > Google & YouTube.
- Under Settings, look for the Google Analytics section.
- You should see the option to connect a Google account. If an account is already connected, it will often display the name and ID of the associated GA4 property. Ensure this matches your "G-" Measurement ID.
By following these steps, you can directly confirm which property your store uses without ever needing to look at code.
Final Thoughts
Verifying your Google Analytics 4 setup doesn't have to be a technical headache. By starting in the GA4 admin, checking your website's source code, or using a simple browser extension like Tag Assistant, you can quickly gain confidence that your data collection is up and running. These methods allow everyone from beginners to experienced developers to verify tracking in just a few minutes.
Once you’ve confirmed GA4 is collecting all that valuable data, the real challenge begins: turning that data into actionable insights without spending hours caught in complex reporting loops. With a tool like Graphed, you can connect your Google Analytics account in seconds and instantly start building dashboards or asking questions using plain English. Instead of figuring out GA4's reporting interface, just ask things like, "Which marketing channels brought in the most new users last month?" and get an answer immediately, helping you get to the insights without the friction.
