Google Analytics 4 (GA4) is the current version of Google's free analytics platform. For a small website, its value is simple: it tells you how many people visit, where they come from, what they do, and which pages they look at. The interface can be overwhelming at first — but the reports that matter most are a small subset.
Setting Up GA4
- Go to
analytics.google.comand sign in. - Create a new property, select GA4, and follow the setup wizard.
- Add the measurement code to your website — a JavaScript snippet added to every page's
<head>. Most CMS platforms (WordPress, Shopify) have built-in or plugin-based GA4 integration. - Verify it's working in the Real-time report (Reports → Realtime) while visiting the site from another tab.
The Reports You'll Actually Use
Traffic Overview
Reports → Acquisition → Traffic Acquisition — shows where visitors come from: organic search, direct, social, referral, email.
Pages and Screens
Reports → Engagement → Pages and Screens — shows which pages get the most views and which have the longest engagement time.
Users Over Time
Reports → Lifecycle → Acquisition → Overview — shows total users, new users and sessions over a date range.
Real-Time
Reports → Realtime — shows who's on the site right now. Useful for checking whether a new post or campaign is generating immediate traffic.
Key Metrics to Understand
| Metric | What it means |
|---|---|
| Users | Unique visitors in the period |
| Sessions | Individual visits (one user can have multiple sessions) |
| Engaged sessions | Sessions lasting over 10 seconds, having a conversion, or viewing 2+ pages |
| Engagement rate | Percentage of sessions that were "engaged" (replaces bounce rate as the headline metric) |
| Views | Total page views |
Reading Traffic Sources
In Traffic Acquisition, the "Session default channel group" column groups traffic into categories:
- Organic Search — from Google, Bing, etc.
- Direct — typed URL or no referrer (also catches some email and app traffic where the referrer is stripped)
- Organic Social — from social platforms without paid promotion
- Referral — from links on other websites
- Email — tracked email links (usually requires UTM parameters — see what are UTM parameters and how to use them)
A Monthly Review Habit
Once a month, check: which pages got the most visits, which traffic source grew or shrank, and whether any pages that should be popular aren't. This doesn't require hours — a 15-minute look at three reports covers the essentials for most small sites.
