🚀 GA4 vs Universal Analytics: What Changed?
If you’re still adjusting to GA4, here’s a quick refresher:
-
🔁 Events now replace pageviews/sessions as the core measurement
-
📉 Bounce Rate has a new meaning
-
💡 Emphasis is on user engagement, not just traffic
-
📱 Cross-platform tracking (web + apps) is now seamless
Let’s break down the key metrics you need to master. 👇
🔍 GA4’s Most Important Metrics — Explained Clearly
1. 👤 Users
-
Total Users: Everyone who visited your site.
-
New Users: First-time visitors tracked via cookies.
Why it matters: If your total and new user count are growing, your SEO, social, and campaigns are working.
2. 📊 Sessions
-
A session begins when a user lands on your site and ends after 30 minutes of inactivity.
-
GA4 sessions are built on events, not just pageviews.
Why it matters: Declining sessions could signal UX issues or less relevant traffic.
3. ⚡ Engaged Sessions
A session is “engaged” if:
-
It lasts 10+ seconds
-
Includes a conversion
-
Or includes 2+ pageviews
Why it matters: This metric replaces bounce rate and gives better insight into visitor quality.
4. ⏱️ Average Engagement Time
-
Measures active time spent on your site (no idle tabs).
Why it matters: High engagement time = sticky, valuable content. Great for SEO performance analysis.
5. 📉 Bounce Rate (GA4 Style)
-
Now defined as:
100% – Engaged Session Rate
Why it matters: A high bounce rate = your content or UX isn’t holding attention.
6. 📄 Page Views (aka Views)
-
Tracks all page loads (including repeats).
-
Pair with unique page views for clarity.
Why it matters: Identify which blog posts or pages drive SEO wins.
7. 🎯 Event Count
In GA4, everything is an event:
-
page_view,scroll,click,video_start,form_submit, etc.
Why it matters: Fine-tune your strategy based on actual user behavior.
8. 🏆 Conversions
-
Any event you label as a conversion (e.g., form submits, purchases).
-
Set in: Admin > Events > Mark as Conversion
Why it matters: Conversions tie your SEO and content efforts to business results.
9. 🌐 Traffic Acquisition (Source / Medium)
-
Source: Where the user came from (e.g., Google, Instagram)
-
Medium: Type of traffic (e.g., organic, cpc)
Why it matters: Track how SEO performs vs. ads, email, and other channels.
10. 🧲 Landing Pages
-
The first page a user visits.
Why it matters: See which content draws in search traffic.
In GA4: Reports > Engagement > Pages and Screens > Filter: session_start
11. 🚪 Exit Pages
-
The last page a visitor saw before leaving.
Why it matters: High exits may signal poor content, slow load, or missing CTAs.
12. 🌍 Demographics
-
Age, gender, country, language (if enabled).
Why it matters: Customize your content and UX for the audience you actually attract.
13. 🖥️ Tech Report
-
Devices, browsers, OS, screen sizes.
Why it matters: Know how your site performs across devices. Prioritize mobile optimization if needed.
