With Google Analytics 4 (GA4), advertisers understand what happens after a user clicks on an ad. By diving into the metrics GA4 provides, you can fine-tune your campaigns, improve user engagement, and drive better results.

Here, we break down the essential GA4 metrics every advertiser should pay attention to and how they can be used to optimize your advertising efforts.

Understanding Post-Click Behavior

Metrics in ad platforms tell you how well your ads are performing, but they don’t provide the complete picture. GA4 helps you understand what users do once they arrive at your site. 

For example:

  • Time on Site: How much time are users spending on your landing pages? Are they exploring other pages?
  • New vs. Returning Users: Are your ads attracting first-time visitors or bringing back existing users?
  • Multichannel Attribution: What other channels have driven users to your site?
  • Content Engagement: Are users watching embedded videos, scrolling through your pages, or downloading resources?
  • Cart Abandonment: What percentage of users add items to their carts but don’t complete their purchases?

Did You Know? Websites with video content see 88% more engagement on average than those without, emphasizing the importance of tracking video interactions.

GA4’s metrics answer these questions and more, giving you actionable insights to optimize your campaigns.

Key Metrics to Monitor in GA4

1. Key Event Counts & Rates

Key events in GA4 are tied to your business objectives. These could include actions like form submissions, account creation, purchases, or event registrations. Identifying and tracking these events can reveal how effectively your site drives desired actions.

  • Event Counts & Rates: Measure the frequency of key events and calculate the percentage of sessions that result in these actions.
  • Performance by Channel: Compare key event rates across paid search, social, and other channels to identify top-performing sources.
  • Landing Page Analysis: Determine which pages drive the highest event rates and consider amplifying their visibility.
  • Attribution Models: Use GA4’s attribution tools to evaluate how different models (last-click vs. data-driven) assign credit to your campaigns.

Note: Data-driven attribution leverages historical data to allocate credit across touchpoints, offering a more nuanced view of user behavior.


2. Engagement Metrics

GA4 introduces engagement-focused metrics, moving beyond the traditional bounce rate. These metrics provide insights into how users interact with your site:

  • Engaged Sessions: Sessions that last more than 10 seconds, include multiple page views or trigger a key event.
  • Engagement Rate: The percentage of sessions that qualify as “engaged.” Higher rates indicate more meaningful interactions.
  • Average Engagement Time: Understand how much time users spend engaging with your content.
  • New vs. Returning Users: Identify channels driving first-time visits versus those encouraging repeat traffic.

Pro tip: If a campaign has a low engagement rate, assess whether the landing page content aligns with user expectations or if the audience targeting needs adjustment.

3. General Event Counts & Rates

Beyond key events, general events offer clues to user behavior and engagement. Enhanced Measurement in GA4 tracks actions like scrolls, file downloads, and video interactions.

  • Scroll Tracking: See if users are engaging with content below the fold.
  • Video Engagement: Analyze how far users watch embedded videos and whether they take action afterward.
  • Download Activity: Gauge interest in downloadable content like PDFs or spec sheets.
  • Custom Events: Set up tailored events for advanced tracking based on your specific goals.

If a significant portion of users download an ebook but don’t proceed to other actions, consider adding a follow-up email capture or call-to-action on the download page.

For e-commerce advertisers, GA4 provides a wealth of data to understand the entire purchase funnel:

  • Transactions: The total number of purchases.
  • Revenue: Use revenue metrics to calculate return on ad spend (ROAS).
  • Cart Abandonment: Identify friction points in the checkout process by analyzing the add-to-cart and checkout completion rates.
  • Lifetime Value: Understand the long-term value of customers acquired through specific campaigns.

If abandonment rates are high, consider optimizing your checkout process or offering limited-time discounts to encourage completion.

5. Ad Platform Integration Metrics

When linked with your Google Ads account, GA4 enhances your data analysis by integrating ad platform metrics directly. This allows for seamless tracking of campaign performance and its correlation with site engagement.

  • Campaign Performance: Analyze key metrics like % engaged sessions, events per session, and average engagement duration.
  • Cross-Platform Insights: Import cost data from non-Google platforms to compare ROAS across all channels.
  • Conversion Reports: View Google Ads conversions alongside organic and other paid channel data for a holistic view.

Pro Tip: Use auto-tagging in Google Ads to ensure accurate data flow into GA4.

Segmenting and Applying Data

Understanding GA4 metrics is only half the battle; the real value comes from actionable segmentation and application:

  1. Channel-Level Analysis: Compare performance across channels to identify the most efficient drivers of qualified traffic.
  2. Landing Page Optimization: Use engagement and event data to refine the content and layout of your landing pages.
  3. Reporting: Incorporate GA4 insights into your PPC reports to demonstrate the impact beyond ad platform data.
