Google Analytics 4: The 5 Numbers Every Small Business Owner Should Actually Track

Google Analytics 4: The 5 Numbers Every Small Business Owner Should Actually Track

Most small business owners have Google Analytics installed — and most of them never look at it.

Part of that is the interface. GA4 is genuinely intimidating if you didn't set it up yourself. The dashboards are dense, the terminology changed from Universal Analytics, and there are dozens of reports that don't obviously apply to a local plumbing company or a cleaning service.

But the bigger issue is not knowing which numbers to actually care about. And for a local service business, that list is short.

Here are the five metrics worth your attention — and what each one is telling you.

---

1. Users (and Where They Came From)

The "Users" metric tells you how many unique people visited your site in a given period. That's your baseline — how much traffic are you actually getting?

But the number by itself is almost meaningless. What matters is where they came from.

In GA4, go to Acquisition → Traffic Acquisition to see your traffic broken down by source:

• Organic Search — found you on Google. This is your SEO working.
• Direct — typed your URL directly or came from a saved bookmark. Usually repeat visitors or word-of-mouth.
• Referral — came from another website linking to you.
• Organic Social — came from Facebook, Instagram, etc.

If 90% of your traffic is Direct and almost nothing is Organic Search, your SEO has room to grow. If you just ran a Facebook campaign and see a spike in Organic Social, that tells you it worked.

This breakdown tells you which marketing channels are actually driving people to your site.

2. Engaged Sessions

In the old Universal Analytics, everyone tracked "Bounce Rate" — the percentage of visitors who left after one page. GA4 replaced that with Engaged Sessions.

An Engaged Session is one where the user either:

• Stayed on your site for more than 10 seconds
• Viewed more than one page, or
• Completed a conversion event (like filling out a form)

The metric you want to watch is Engagement Rate — the percentage of sessions that were engaged. For a local service website, 50–65% is a reasonable benchmark. Below 40% means visitors are landing and leaving fast, which is a signal that either your traffic isn't well-targeted or your site isn't giving people what they expected.

3. Conversions

This is the big one — and it requires setup.

A "conversion" in GA4 is any action you define as valuable: a contact form submission, a click on your phone number, a booking. By default, GA4 doesn't know what matters to your business. You have to tell it.

If you're working with a web designer or developer, ask them to set up conversion tracking for your contact form submissions and phone number clicks. If your site was built with Google Tag Manager, this is straightforward.

Once it's set up, go to Reports → Engagement → Conversions to see how many people are taking action on your site each month. This is the only metric that directly ties your website to real business outcomes.

If you're getting 500 visitors a month and zero conversions, your site has a problem. If you're getting 200 visitors and 20 form submissions, your site is doing its job.

4. Landing Pages

Not all pages on your site perform equally. The Landing Pages report (under Reports → Engagement → Landing Page) shows which pages people arrive at first — and how those pages perform.

For a service business, your homepage and individual service pages should be doing most of the heavy lifting. If you find that people are landing on a blog post you wrote two years ago but leaving immediately, that page might need a better call to action or a link to your services.

Pay attention to which landing pages have high engagement rates vs. low ones. A service page with 35% engagement rate is telling you something needs to change — maybe the headline doesn't match what people searched for, or the page loads slowly on mobile.

5. Pages by Device Category

Go to Reports → Tech → Tech Overview and look at how your traffic breaks down by device: Desktop, Mobile, Tablet.

For most local businesses, 60–75% of traffic comes from mobile phones. If yours is significantly different — say, only 30% mobile — that's worth investigating.

More importantly, check whether your engagement rate is dramatically lower on mobile than desktop. If desktop visitors have a 60% engagement rate and mobile visitors have a 30% engagement rate, your mobile experience is the problem. That could mean slow load times on phones, a layout that breaks on smaller screens, or buttons that are too small to tap.

This one report has a clear, direct fix: improve the mobile version of your site.

A Simple Monthly Routine

You don't need to live in GA4. A 10-minute monthly check is enough:

• Total users vs. last month — growing, flat, or dropping?
• Traffic sources — are organic search numbers improving?
• Conversions — how many form fills or calls this month?
• Engagement rate — is it above 50%?
• Mobile vs. desktop engagement — any big gap?

Write the numbers down somewhere. Trends over 3–6 months tell you a lot more than any single month's data.
