What is a Google Analytics ID Example?

Your Google Analytics ID is the unique string of characters that links your website to your Google Analytics account, making all your website traffic and user behavior tracking possible. Getting this setup right is the first step to understanding your audience. This guide explains what the ID is, shows you what the different versions look like, and gives you a step-by-step walkthrough on how to find and install it.

What is a Google Analytics ID?

Think of your Google Analytics ID as a mailing address for your website's data. When a user visits your site, a small piece of tracking code (called a tag) fires. This code needs to know where to send all the juicy data it collects - like which pages were visited, where the user came from, and how long they stayed. The Google Analytics ID in that code snippet tells it, "Send the data to this specific property in Google Analytics."

Without this ID, the data would have nowhere to go. It’s what ensures the information from your website ends up in your specific dashboard and not someone else's. Each website or app you track (known as a "property" in GA) gets its own unique ID.

The Two Types of Google Analytics IDs: UA vs. GA4

You may see two different formats for Google Analytics IDs referenced in older blog posts and forums, which can be a source of confusion. This is because Google made a major update to its platform, moving from Universal Analytics to Google Analytics 4. They each have a distinct ID format.

Universal Analytics (UA) Tracking ID

Universal Analytics was the standard for years until it was officially phased out in mid-2023. You might still encounter these IDs on older websites or in legacy setups. A UA Tracking ID always starts with "UA" and follows a specific pattern.

• Format: UA-XXXXXXXX-Y
• Example: UA-11223344-1

Here’s a simple breakdown of the format:

• The UA prefix stands for "Universal Analytics."
• The set of X’s (11223344) represents your personal account number.
• The final -Y (-1) is the property index number associated with that account. You could have UA-11223344-2, UA-11223344-3, etc., for different websites under the same account.

Again, this format is for the older, sunsetted version of Google Analytics. All new properties will use the GA4 format.

Google Analytics 4 Measurement ID

Google Analytics 4 is the current and only standard for Google Analytics. It works differently from UA, focusing on events a user takes rather than sessions they start. With this change came a new ID format called the Measurement ID.

• Format: G-XXXXXXXXXX
• Example: G-E5N1P3R7K9

The Measurement ID is much simpler. It always starts with a "G-" prefix, followed by a combination of letters and numbers. This ID is used for your GA4 "data stream" - the source of data flowing into your GA4 property (e.g., your website or mobile app).

For all new analytics setups, you will be looking for and using a G- Measurement ID.

Step-by-Step: How to Find Your Google Analytics ID

Finding your G- Measurement ID is a straightforward process inside the Google Analytics dashboard. You just need to know where to click. Here are the steps:

1. Log in to Google Analytics: Go to the Google Analytics website and sign in to your account.
2. Go to the Admin Section: In the bottom-left corner of the page, click the Admin icon (it looks like a gear). This will take you to the backend settings panel for your account and properties.
3. Select the Correct Property: Ensure you have the correct GA4 Property selected in the middle "Property" column. If you have multiple websites, you'll see a dropdown menu right below 'Property settings' that you can use to select the appropriate one.
4. Click on "Data Streams": In the "Property" column, find and click on Data Streams. A data stream is the pipeline that funnels data from your website or app into GA4.
5. Select Your Web Stream: You'll see a list of your data streams. For a website, you should have one listed. Click on it to open its details.
6. Find Your Measurement ID: On the "Web stream details" page, your Measurement ID will be prominently displayed in the top-right corner. It will be labeled "MEASUREMENT ID" and start with "G-". You can easily copy it by clicking the clipboard icon right next to it.

Beyond the ID: Understanding the Google Tag (gtag.js)

Simply finding your Measurement ID is only half the battle. On its own, the ID is just a string of text. To make it work, it needs to be placed inside a piece of JavaScript code called the Google Tag (gtag.js).

This tag is the actual tracking script that you install on your website. When a user loads a page, their browser runs this script, which then collects the data and sends it back to your GA4 property using your unique Measurement ID.

A standard Google Tag snippet for GA4 looks like this:

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [],
  function gtag(){dataLayer.push(arguments),}
  gtag('js', new Date()),

  gtag('config', 'G-XXXXXXXXXX'),
</script>

Notice your G-XXXXXXXXXX Measurement ID appears twice in this snippet. This entire block of code needs to be placed within the <head> section of every single page on your website that you want to track.

3 Common Ways to Install Your Google Analytics Tag

Putting code on your website might sound intimidating, but there are several ways to do it depending on your comfort level and the platform your site is built on.

1. Manual Installation

This is the direct approach. You copy the entire Google Tag snippet from your GA4 data stream settings and paste it directly into your website’s HTML code, just before the closing </head> tag. This is a good option if you have a simple static website or are comfortable editing your theme's header.php file in a system like WordPress. The downside is that you have a higher chance of making an error if you aren't familiar with code.

2. Using a CMS Integration or Plugin

Most modern content management systems (CMS) make this process incredibly simple. Platforms like WordPress, Shopify, Squarespace, and Wix have built-in integrations or official plugins for Google Analytics. Typically, all you have to do is:

• Install the official Google plugin or navigate to the marketing integrations section.
• Find the field for "Google Analytics Measurement ID."
• Copy just your G-XXXXXXXXXX ID (not the whole code snippet) and paste it into the field.
• Save your changes.

The platform handles adding the code to the right place for you. This is the recommended method for most users as it's quick, easy, and minimizes the risk of breaking your site.

3. Using Google Tag Manager (GTM)

For those who need more advanced tracking, Google Tag Manager is the way to go. GTM is a free tool that acts as a container for all your marketing and analytics scripts (like the GA tag, Facebook Pixel, etc.). The process involves:

1. Installing the GTM container snippet on your site once.
2. Setting up a "Google Analytics: GA4 Configuration" tag inside the GTM interface.
3. Pasting your Measurement ID (G-XXXXXXXXXX) into that tag's configuration.

The major benefit here is that you can manage dozens of tags without ever needing to touch your website's code again after the initial setup. It centralizes your tracking scripts and empowers you to deploy complex event tracking without developer help.

Final Thoughts

Locating and installing your Google Analytics ID is the foundational step for gathering data about your website’s performance. By understanding the difference between the old UA IDs and the new GA4 Measurement IDs, you can confidently find your G- ID in the Admin section and use it to connect your website to Google's powerful analytics platform.
