Google Analytics 4 can feel overwhelming, but a small business only needs five numbers: active users, engaged sessions, traffic sources, key events and top pages. Together they show how many people visit, whether they stay, where they come from, what they do that matters, and which pages earn their keep.
Key takeaways
- Check five things monthly: active users, engaged sessions, traffic sources, key events and top pages.
- As of October 2026, Google calls important actions "key events"; "conversion" now refers to actions used in Google Ads.
- A GA4 setup is a short, numbered job: property, data stream, tag, test, key events.
- GA4 shows what happened on your site, not why, and it does not show the searches that brought people.
- Pair GA4 with Google Search Console: one shows behavior on your site, the other shows how people found it.
Which five numbers actually matter?
GA4 offers hundreds of metrics. A busy owner needs a short list that answers real questions. Use these five, check them once a month, and write the result in a notebook so you can see direction over time.
| Number | Question it answers | What to do with it |
|---|---|---|
| Active users | How many real people visited? | Compare this month with last month and the same month last year. |
| Engaged sessions | Did visitors actually look around? | If engagement is low, check page speed and whether the first screen matches what people searched for. |
| Traffic sources | Where do visitors come from? | Double down on the channels that bring customers; fix the ones that bring only clicks. |
| Key events | Did visitors do something that matters? | Track calls, form submissions, bookings or purchases, and watch which pages lead to them. |
| Top pages | Which pages get the attention? | Improve the busiest pages first and link them to your booking or contact page. |
What do users and engaged sessions mean?
Google's help pages define total users as the number of people who visited your site in a date range, and active users as the number of people who engaged with it. In standard reports GA4 shows active users. That is the number to quote when someone asks how many people visit your site, and it is a better measure than raw page loads.
A session is a period during which a user is engaged with your website. Google counts a session as engaged if it lasts longer than 10 seconds, has a key event, or has two or more page or screen views. The engagement rate is the percentage of sessions that were engaged.
In plain English: if a lot of sessions are not engaged, people are leaving quickly. That can point to a slow page, a confusing first screen or traffic from the wrong audience. Our guide to how fast a website should load explains the speed side of that problem.
Where is my traffic coming from?
Traffic sources group visits into channels such as organic search, direct, referral, email and social. For a local business the useful questions are simple. Is organic search growing? Do email or social campaigns bring people who stay? Is most traffic "direct" because people type your name, or because tracking is incomplete?
Treat the channel report as a guide, not a ledger. Some visits cannot be attributed to a source, and different tools count differently. Look for direction month over month rather than exact figures.
What are key events, and what happened to conversions?
Google's Analytics Help says a key event is an event that measures an action that is particularly important to the success of your business. As of October 2026, Google reserves the word "conversion" for an important action you use to measure the performance of ad campaigns and to optimize bidding. In Analytics reports, the actions you care about are called key events.
For a service business, the usual key events are a form submission, a click on your phone number, a booking confirmation, or a purchase. A purchase on a web store is marked as a key event automatically, according to Google. Other events you mark yourself, and the setup steps below show how.
How do I set up GA4 in five steps?
- Create a Google Analytics account and a GA4 property for your website, using a Google account that your business controls and that you will not lose if a contractor leaves.
- Add a web data stream with your website address. Google then gives you a measurement ID that starts with G-.
- Install the tag. Many website platforms let you paste the measurement ID into a settings field; otherwise a developer adds the tag to every page.
- Test it. Open your site in another browser tab, then look at the Realtime report in GA4 to confirm your visit appears.
- Mark key events. In Admin, open Events and click the star next to the event you want to track, or create a new event and switch on "Mark as key event."
If you would rather have this done and checked, our Google Analytics & Search Console Setup is $139. Keep the account in your own name either way, so you own your data.
What can't GA4 tell you?
GA4 records activity on pages that have its tag. It cannot tell you who a visitor is, why they left, or what happened on a phone call you never tracked. It also does not list the exact searches that brought people to your site. That is the job of Google Search Console, which reports search queries, impressions and clicks for your site.
Pairing the two gives a fuller picture: Search Console shows what people searched before they arrived, and GA4 shows what they did next. If you suspect your site is quietly losing visitors, read signs your website is costing you customers and pair it with these five numbers.
Finally, remember that numbers do not fix anything on their own. Pick one change a month, such as a faster page or a clearer booking button, and see what moves. If you do not have a website to measure yet, a Basic Website starts at $450.
Frequently asked questions
Is Google Analytics 4 free?
Yes, the standard version of Google Analytics 4 is free to use, and that is what most small businesses need. There are paid options for very large organizations, but a local service business, restaurant or shop rarely needs them. Your cost is the time to set it up correctly and to read it each month, which is why a short list of five numbers helps.
What is a good engagement rate?
We would not quote a universal number, because it varies by industry, page type and traffic source. Google defines engagement rate as the percentage of sessions that were engaged, meaning they lasted longer than 10 seconds, had a key event or had two or more page views. Compare your own rate month to month and look at which pages and sources have the lowest engagement first.
What is the difference between a key event and a conversion?
As of October 2026, Google's Analytics Help says a key event is an event that measures an action that is particularly important to the success of your business. The word conversion now refers to an important action used to measure ad campaign performance and optimize bidding. For most small businesses, you will mark key events in Analytics and only meet conversions if you run Google Ads.
How often should I check my analytics?
Once a month is enough for most small businesses. Open the five numbers, compare them with last month and the same month last year, write down one observation and decide on one change. Check sooner after a site redesign, a new ad or an email campaign. Daily checking tends to create worry over normal ups and downs without leading to better decisions.
Do I need Google Search Console as well as GA4?
They answer different questions, so using both gives a better picture. Search Console reports how your site appears in Google Search, including queries, impressions and clicks. GA4 reports what visitors did once they arrived. If you only have one, you can see either how people found you or how they behaved, but not the link between the two.
Can you set up Google Analytics for my website?
Yes. Our Google Analytics & Search Console Setup is $139, and a human checks the result. You keep ownership of the accounts. We do not promise traffic or rankings; the setup makes sure the numbers are being collected correctly so you can make decisions. Reading the reports and acting on them remains your decision, though we can walk you through the five numbers.
