What is the Latest Version of Google Analytics?

The latest and current version of Google Analytics is Google Analytics 4, often shortened to GA4. This version fully replaced the older Universal Analytics (UA) on July 1, 2023, marking a significant shift in how websites and apps measure user traffic and engagement. This article explains the key differences between these versions, what prompted the change, and what the new event-based model means for your reporting.

A Quick Answer: The Standard is Now Google Analytics 4

If you're setting up analytics for a new website or wondering which version to use, the one and only option is Google Analytics 4. The previous generation, Universal Analytics (often referred to as UA or GA3), stopped processing new data for standard properties in July 2023. While you might still access historical UA data, all active data collection now happens exclusively through GA4.

It’s important to understand that GA4 isn't just an update, it is a complete rebuild of the platform from the ground up. It has a fundamentally different data collection model, a new user interface, and features designed for the future of the web.

Why the Big Change? Moving From an Old Model to a New Reality

For roughly a decade, Universal Analytics was the gold standard for web analytics. So why did Google feel the need to completely overhaul it? The simple answer is that the way we use the internet changed dramatically, and UA's underlying structure couldn't keep up.

The Old Way: A Session-Based Model

Universal Analytics was built around the concept of "sessions" or "visits." Think of it like a cashier counting how many people walk into a retail store. Every metric - like pageviews, bounce rate, and time on page - was tied to that single visit. When a user came to your website, a session started. When they left, the session ended.

This model worked perfectly in a world where users primarily visited your website from a desktop computer during a single, uninterrupted browsing session. But that’s no longer how real user behavior looks.

The New Reality: Privacy and Cross-Platform Journeys

Today, the customer journey is fragmented. A user might discover your brand on their phone through an Instagram ad, browse your product pages on their laptop later that day, and finally make a purchase through your mobile app a week later. Universal Analytics, with its reliance on browser cookies and session-based tracking, struggled to connect these dots into a single, cohesive user timeline.

Furthermore, growing privacy regulations like GDPR and the slow phasing out of third-party cookies made UA’s tracking methods less reliable and sustainable. A new approach was needed - one that respected user privacy while still providing businesses with valuable insights.

GA4's Solution: An Event-Based Model

Google Analytics 4 ditches the rigid session-based model for a much more flexible, event-based model. In GA4, everything is an event.

A page view? That's a page_view event. A user scrolling down 90% of the page? That's a scroll event. Someone clicking a link, submitting a form, or watching a video? These are all tracked as distinct events. This approach allows you to measure a continuous series of user interactions across different devices and platforms - including both websites and mobile apps - without being restricted to the concept of a "session." It’s a subtle but powerful shift from counting visits to understanding user actions.

What's Actually New in GA4? Key Changes You Need to Know

The move from UA to GA4 brings more than just a philosophical change in data modeling. The entire platform, from the interface to the reports you see, has been redesigned. Here are the most significant changes you'll encounter.

Brand New Data Model: Events Are Everything

As mentioned, every user interaction is now an event. Unlike UA, where events were a special category of hit with a "Category," "Action," and "Label," GA4 events are much simpler and more flexible. They consist of an event name (e.g., add_to_cart) and optional parameters that provide more context (e.g., item_name: "Running Shoes", price: 99.99).

One of the best new features is "Enhanced Measurement." When you set up a GA4 property, it automatically tracks essential events out of the box with no extra coding required. These include:

• Page views (page_view)
• Scrolls (scroll)
• Outbound clicks (click with an outbound parameter)
• Site search (view_search_results)
• Video engagement (video_start, video_progress, video_complete)
• File downloads (file_download)

This makes it far easier for new users to start collecting meaningful data right away.

A Unified View of App and Web Data

This is a game-changer for businesses with both a website and a mobile app. In the past, you needed separate properties to track web (using Universal Analytics) and app (using Firebase Analytics) data. This made it nearly impossible to see the full customer journey.

GA4 solves this by using "Data Streams." You can have a data stream for your website, one for your iOS app, and one for your Android app, all feeding data into the same GA4 property. This allows you to track and analyze the total user experience in one place.

Simplified Account Structure

The old UA hierarchy was Account > Property > View. "Views" were essential for filtering data - for example, creating a view that excluded internal traffic or only showed traffic to a specific subdomain. In GA4, the structure is simplified to just Account > Property.

The concept of "Views" is gone. Instead, filtering and segmentation are now handled through data filters within the admin settings and powerful, on-the-fly comparisons in the reporting interface.

A Completely Redesigned Interface and Reports

When you first log in to GA4, you might feel a bit lost. The familiar sidebar with dozens of pre-built reports from UA has been replaced with a much smaller, more focused set of reports, including:

• Reports Snapshot: A bird's-eye view dashboard of key metrics.
• Realtime Report: See what users are doing on your site right now.
• Acquisition Reports: Understand where your users are coming from.
• Engagement Reports: See what content users are interacting with.
• Monetization Reports: Track revenue from e-commerce and in-app purchases.

For custom, in-depth analysis, Google has moved most of the functionality into the Explore section. This is where you can build free-form explorations, funnel reports, and path explorations - similar to what was only available in the paid Google Analytics 360 version of UA.

Focus on Engagement Instead of Bounces

One of the most talked-about changes is the 'death' of Bounce Rate. GA4 replaces it with engagement metrics, which are more nuanced. An Engaged Session is a session that meets one of these criteria:

• Lasts longer than 10 seconds.
• Includes a conversion event.
• Has at least 2 pageviews or screenviews.

From this, you get new metrics like Engagement Rate (the percentage of sessions that were engaged) and Average Engagement Time. These metrics provide a much better indicator of whether users are actually finding value in your content, rather than simply measuring who left after viewing a single page.

Do You Still Need to Worry About Universal Analytics?

For day-to-day work, no. Universal Analytics is a thing of the past for active marketing and analytics. It no longer collects data, so any new campaign or site activity will not appear there.

However, your historical UA data is a valuable archive. For years, all your website's performance was measured there. If you need to do year-over-year comparisons that extend back beyond July 2023, you’ll need to refer to your old UA datasets. Many businesses have downloaded archives of their UA reports to spreadsheets or other BI systems so they can reference this data indefinitely. But moving forward, all your efforts, learning, and reporting should be focused solely on mastering Google Analytics 4.

Final Thoughts

In short, the latest version of Google Analytics is GA4, a fundamental reimagining of web analytics. It moves from a session-centric model to a user-centric, event-based framework that's better equipped for today's cross-platform user journeys and privacy-conscious internet. While it can feel intimidating at first, its flexibility and power make it an essential tool for understanding modern user behavior.

Making sense of GA4's new event-based model and learning to build custom reports in the "Explore" section can be a heavy lift, especially when you just need quick answers about your performance. We built Graphed to connect directly to your Google Analytics 4 account and eliminate that complexity. Instead of wrestling with a new interface, you can simply ask questions in plain English, like "Show me transactions and revenue from organic search traffic last month," and get instant, real-time dashboards that just work.
