Your Google Analytics Report, Explained
What every number in GA4 means, where it misleads, and which ones matter for your business.
Overview
Read this with your report open
Open Google Analytics and you get a wall of numbers: sessions, active users, new users, engagement time, key events, revenue. Each one answers a different question about your business, and none of them means much on its own. This guide explains what each number actually counts, what it is good for, where it misleads, and which ones deserve your attention depending on the kind of business you run.
Throughout, we use an example row like the one at the top of a GA4 Landing page report. These are made-up numbers for a small business over 28 days, not a client’s data:
| Sessions | Active users | New users | Avg. engagement time / session | Key events | Total revenue |
|---|---|---|---|---|---|
| 1,200 | 980 | 860 | 38s | 24 | $1,940 |
First: where these numbers come from
The Google tag on your site (installed directly or through Google Tag Manager) sends a small message to Google Analytics 4 every time something happens: a page loads, someone scrolls, a form is sent, a purchase completes. GA4 stores those events and turns them into the reports you see. Tag Manager is the delivery truck; GA4 is the warehouse. The numbers live in GA4, not in Tag Manager.
Two things every owner should know before trusting any single number:
- It is a sample of reality, not a census. Ad blockers, privacy browsers and visitors who decline cookies are partly or fully missing. Compare trends over time rather than treating any count as exact.
- It only counts what is set up. If your contact form or booking button isn’t tracked as a key event, GA4 will happily report zero leads while your inbox fills up.
The numbers, one by one
Sessions
What it counts: visits. A session starts when someone arrives and ends after 30 minutes of inactivity (GA4’s default). One person visiting Monday and again Thursday is two sessions.
What it tells you: how much attention your site gets, and from where. Watch out: sessions going up is only good news if the right people are coming. A spike from a bot or a viral post can double sessions and add zero customers.
Active users
What it counts: distinct people (really, distinct browsers or devices) who had an engaged session or whose visit GA4 could register as active. It is the main “users” number in GA4 reports. In our example, 1,200 sessions came from 980 people, so some came back.
Watch out: the same person on a phone and a laptop usually counts twice. Users are an estimate of people, not a headcount.
New users
What it counts: people visiting for the first time (as far as GA4 can tell). In the example, 860 of 980 were new.
What it tells you: whether your marketing is reaching new people. A healthy business usually needs both new users and returning ones: new users fill the top of the funnel, returning users are where repeat sales come from.
Engaged sessions and engagement rate
What it counts: GA4 calls a session “engaged” if it lasts longer than 10 seconds, includes a key event, or views 2 or more pages. Engagement rate is engaged sessions divided by all sessions. (Bounce rate in GA4 is simply the opposite: the share of sessions that were not engaged.)
What it tells you: whether visitors found something worth staying for. A landing page with lots of sessions and a low engagement rate is usually a mismatch between the ad or post that sent people and the page they landed on.
Average engagement time per session
What it counts: how long your page was actually in front of the visitor (the tab in focus, the app in the foreground), averaged across sessions. Time in a background tab doesn’t count.
What it tells you: attention. Five seconds on a landing page usually means people didn’t find what the ad promised; two minutes on a services page usually means they are reading. Watch out: longer isn’t always better. On a checkout or booking page you want people to finish fast.
Key events
The number that pays the bills
What it counts: the actions you have told GA4 matter: a form sent, a call button tapped, a booking made, a purchase. (Google renamed “conversions” to “key events” in 2024; the idea is the same.) The “All events” dropdown above the column lets you see each one separately.
What it tells you: whether visits turn into business. Divide key events by sessions and you have a key event rate: 24 ÷ 1,200 = 2% in our example. That rate, by page and by traffic source, is where most of our recommendations start.
Total revenue
What it counts: money GA4 can see: online purchases (and subscription or ad revenue, if set up), minus refunds. It only appears if your store sends purchase data.
Watch out: it won’t include phone orders, invoices or in-person sales. For service businesses, revenue in GA4 is often $0 even in a great month; key events are the better signal.
Landing page
What it is: the first page of each session, the page people “land” on. The Landing page report shows every metric above, page by page.
Why it matters: it connects your marketing to your website. If an ad sends people to a page that doesn’t match the ad, this report is where it shows: high sessions, low engagement time, no key events.
Which numbers matter for your kind of business
Every business can see every metric, but they don’t all deserve the same attention. Here is where we look first:
Pick two, watch them monthly
| Business | Watch first | Why |
|---|---|---|
| Professional services | Key events (consult bookings, calls, forms) by landing page; engagement time on service pages | Each client is worth a lot, so a handful of extra inquiries matters more than traffic. Reading time on service pages shows whether your expertise is coming across. |
| E-commerce | Total revenue, key event rate (purchases ÷ sessions), revenue by landing page and source | Revenue is directly measurable, so you can see which products, pages and ads actually pay back. |
| Restaurants | Key events for directions, calls, online orders and reservations; new vs. returning users | Most of the sale happens offline, so the “intent” clicks are the signal. Returning users show whether regulars are coming back. |
| Community & events | Key events for RSVPs, sign-ups and giving; new users; sessions on event pages | Growth depends on newcomers taking a first step. Event page traffic before a date tells you if promotion is working in time to fix it. |
| Home & local services | Calls and quote requests by source; engagement rate on location pages | Leads usually come from search and maps. Knowing which source sends booked jobs tells you where the next dollar should go. |
How we read your report every month
When SWFT manages your analytics, we look at your numbers the same way every month, so the next move comes from your data, not a hunch:
- Check the tracking is healthy. Are key events still firing? Any spike that looks like a bot or a broken tag?
- Compare like with like. This month vs. last month, and vs. the same month last year, so seasons don’t fool us.
- Find the leaks. Landing pages with plenty of sessions but low engagement or no key events.
- Follow the money. Which sources send key events, and what each one costs.
- Send three moves. A short, plain-English list of what to change next and why.
Closing
Your analytics are a record of what real people did on your site. Read the right numbers for your business, compare them over time, and they will tell you where customers slip away and what to fix next. If you would rather have us read them for you, that is what our Growth Audit is for.
