How to Upgrade to a Google Analytics 4 Property

If you're still using Universal Analytics (UA), your website traffic data stopped being collected on July 1, 2023. The official upgrade path is Google Analytics 4, a complete overhaul of how we measure web activity. This guide provides a clear, step-by-step process to get your GA4 property set up correctly and start collecting data.

First, What Is GA4 and Why Is It So Different?

Think of Universal Analytics as a system built around website sessions and pageviews. It was primarily designed to track how people navigated pages across a single website. GA4 works differently, using a more flexible, user-centric model built around events.

An event can be anything a user does: a page view, a scroll down the page, a button click, a purchase, or a video play. This event-based model is far better at understanding the complete customer journey, whether it happens on a website, a mobile app, or across both.

Advantages of the GA4 Model:

• Cross-Device Tracking: It's much better at understanding when the same user visits from their phone and then their laptop.
• Built-in Privacy: GA4 was designed with modern privacy regulations like GDPR and CCPA in mind, offering more control over data without relying solely on cookies.
• Enhanced Engagement Metrics: Instead of focusing on "Bounce Rate," which could be misleading, GA4 introduces "Engagement Rate" — a measure of time spent on the page, conversions, or at least two pageviews. It’s a much stronger signal of actual user interest.

This is a mandatory switch, but it’s also an opportunity to start with a fresh, more powerful approach to understanding your audience.

Before You Begin: A Quick Pre-Flight Checklist

Jumping straight into the setup can lead to headaches later. A few minutes of prep will ensure a smooth transition.

1. Confirm You Have Administrator Access

You can't create or modify properties without the right permissions. To check, log in to your Google Analytics account, click the 'Admin' gear icon in the bottom-left corner, and make sure your account email is listed under "Property User Management" with the role of "Administrator."

2. Document Your Current UA Setup (Critically Important!)

Your old Universal Analytics data will not migrate over to your new GA4 property. They are two separate datasets. The GA4 Setup Assistant creates a new property, it doesn't "convert" your old one. Take 15 minutes to take screenshots or jot down your most important settings:

• Goals: What user actions are you tracking as conversions? Thank-you page visits? Form submissions? Write them down so you can recreate them in GA4.
• Events: Are you tracking button clicks or PDF downloads with custom event tracking? Document the "Category," "Action," and "Label" for each.
• Filters: Are you filtering out traffic from your own office IP address? Make a note of which filters are active.

This is also the perfect time for a bit of spring cleaning. If you have old goals or events you no longer care about, you don't need to bring them over to your new GA4 setup.

Upgrading with the GA4 Setup Assistant: A Step-by-Step Guide

Google has made the initial creation process relatively painless with a built-in wizard. We'll walk through it and then cover the crucial step of actually getting the tag on your site.

Step 1: Open the GA4 Setup Assistant

Log into your existing Universal Analytics account. Navigate to the Admin area by clicking the gear icon in the bottom left. In the "Property" column, the very first option should be GA4 Setup Assistant. Click on it.

Step 2: Start a New GA4 Property

You'll see a box that says "I want to create a new Google Analytics 4 property." Click the blue Get Started button. A pop-up will explain what the wizard will do. For most users, you simply need to click Create and continue.

Congratulations! You officially have a GA4 property. However, it’s not collecting any data yet. The wizard has created the property, a container is waiting for information. The next — and most important — step is to install the tracking tag on your website.

Step 3: Install the GA4 Tracking Tag

After creating your property, the wizard should take you to the "Setup Assistant" overview page for your new GA4 property. Under Collection, click the arrow next to Data collection and then click on Set up a data stream.

You’ll see a list of your data streams (likely just one for your website). Click it to open the details. Here, in the top right, you'll find your Measurement ID, which will start with "G-". This is the equivalent of your old "UA-" tracking ID.

Now, we need to add this tag to your site. You have a few options.

Option A: Use Google's Connected Site Tag (The Easy Way)

If your website currently uses the newer gtag.js tracking code (most sites have for the last few years), this is your simplest choice. This feature allows your existing UA tag to also send data to your new GA4 property without needing to add any new code to your site.

• In your Universal Analytics property (not GA4), go to Admin > Tracking Info > Tracking Code.
• Under "Connected Site Tags," enter your G- Measurement ID and give it a nickname.
• Click "Connect." That’s it! Data should start appearing in GA4 within the hour.

Option B: Use Google Tag Manager (The Recommended Way)

If you're already using Google Tag Manager (GTM), this is the cleanest and most scalable way to manage your GA4 setup.

1. Log into your GTM account and open the workspace for your site.
2. Go to Tags > New.
3. Give your tag a clear name, like "GA4 — Configuration."
4. Click into Tag Configuration and select Google Analytics: GA4 Configuration.
5. Paste your G- Measurement ID into the Measurement ID box.
6. Leave the "Send a page view event when this configuration loads" box checked. This automatically tracks pageviews.
7. Next, click on the Triggering box below. Select the All Pages trigger. This tells GTM to fire the tag on every page of your website.
8. Save your tag, and then click the blue Submit button in the top right to publish your changes.

Your site is now sending data to GA4 through Tag Manager. This method makes it much easier to add more advanced event tracking later on.

After The Upgrade: Essential First Steps

Just setting up the tag isn’t the finish line. To get the most value out of GA4, you need to configure a few key settings.

1. Verify Data Collection

In your new GA4 property, navigate to Reports > Realtime. Open your website in a separate tab and click around. You should see your own activity appear on the map and in the event cards within a minute or two. If you see activity, you've successfully installed the tag.

2. Extend Your Data Retention Period

This is extremely important. By default, GA4 only stores granular, user-level data for 2 months. You should immediately change this.

• Go to Admin > Data Settings > Data Retention.
• Use the dropdown menu under Event data retention and change it from "2 months" to 14 months.
• Click Save.

This ensures you can analyze seasonal trends and user behavior over a much more useful timeframe.

3. Configure Conversions

In GA4, there are no "Goals" in the way UA had them. Instead, you mark important events as conversions. To recreate a simple "thank you page" goal:

• Navigate to Admin > Events.
• Click Create Event and then Create again.
• Name your custom event (e.g., generate_lead).
• Under Matching conditions, set event_name equals page_view AND page_location contains thank-you (or whatever your confirmation page URL is).
• Save the event.
• After 24 hours, this new event will appear in your Admin > Events table. Simply toggle the switch under Mark as conversion to turn it into a trackable conversion.

4. Link Other Google Products

Finally, go to Admin > Product Links. Be sure to link your GA4 account to Google Ads and Google Search Console. This unlocks critical reporting features, allowing you to see your ad performance and organic search query data directly within your GA4 reports.

Final Thoughts

Making the switch to Google Analytics 4 is a non-negotiable step for anyone serious about tracking website performance. By following the GA4 Setup Assistant and then taking a few minutes to configure key settings like data retention and conversions, you’ll be set up with a powerful, future-proof analytics platform.

Moving your data collection forward is just the first step, the next is connecting it to the rest of your business data — from ad spend to CRM activity — to get a full picture of performance.
