Most business owners have Google Analytics installed and have no idea what it is telling them. Here is what to actually track and what to ignore.
Google Analytics 4 can show you over 200 different metrics. You need three. Everything else is context at best and distraction at worst. The three numbers that actually tell you whether your website is working are visitors, form submissions, and conversion rate. Know those three numbers and you know everything you need to make decisions about your site.
Visitors (Sessions or Users): How many people are coming to your site each month. This is the raw input. Everything downstream depends on getting enough traffic. If you have fewer than 200 visitors per month, conversion rate optimization is a secondary priority — traffic is the problem.
Form submissions (Conversions): How many of those visitors took the action you want them to take — filled out a form, called you, booked a consultation. This is the output. It is the number that directly correlates to revenue.
Conversion rate: Form submissions divided by visitors, expressed as a percentage. A service business website with good traffic and good conversion optimization should be converting between 2 and 5 percent of visitors. Below 1 percent is a clear signal that something is broken. Above 5 percent is excellent.
If you know these three numbers, you can diagnose almost any website problem. Low traffic with decent conversion rate: a traffic problem. Good traffic with low conversion rate: a website or messaging problem. Low traffic and low conversion rate: both problems, fix traffic first.
If you do not have GA4 set up, go to analytics.google.com and create an account. Add your website as a property and follow the setup wizard to generate your tracking code. Install that code on every page of your site — in WordPress this is typically done through a plugin like "Site Kit by Google" or by pasting the code into your theme's header. In Webflow, there is a dedicated Analytics field in the project settings. In Next.js or other frameworks, add the Script tag in your layout file.
Verify the installation is working by opening your site in a browser and checking the GA4 Real-time report. If you see yourself as an active user, the tracking code is working.
This is where most setups break down. GA4 installed does not automatically mean form submissions are tracked. You have to tell GA4 what to count as a conversion.
The cleanest method: when someone submits your contact form, redirect them to a thank-you page with a unique URL (e.g., yoursite.com/thank-you). In GA4, go to Admin → Events → Create Event. Set it to fire when the page_view event occurs and the page URL contains "/thank-you". Then mark that event as a conversion. Now every form submission that lands on your thank-you page is tracked as a conversion.
If your form submits without redirecting (the form just shows a success message on the same page), you will need to use Google Tag Manager to fire a custom event when the form submission succeeds. This is slightly more technical — if you are not comfortable with GTM, this is worth having a developer handle once, and then it runs automatically.
Call tracking is the other major conversion type for service businesses. Tools like CallRail provide a tracking phone number that dynamically replaces your real number for visitors coming from different sources. Every call is logged, attributed to its traffic source, and can be pushed to GA4 as a conversion event. For businesses that close most clients by phone rather than form, call tracking is essential — without it, you have no visibility into a major portion of your actual conversion volume.
Bounce rate: GA4 replaced bounce rate with engagement rate, which is different. Neither metric reliably tells you whether your site is working — a visitor who reads your entire homepage and then calls you directly looks exactly like a visitor who left immediately. Ignore it.
Time on page: A long time on page could mean the visitor found the content valuable. It could also mean they walked away from their computer. It tells you almost nothing actionable.
Page views: Raw page view counts tell you traffic volume but not behavior. A page with 1,000 views and 0 conversions is underperforming. A page with 50 views and 10 conversions is doing excellent work. Look at conversion rate, not page views.
Social media traffic: For most service businesses, social media drives a tiny fraction of revenue-generating traffic. Track it, but do not optimize around it unless the data shows otherwise.
Every Monday, look at three things in GA4: visitors for the past week (compared to the same period last week), conversions for the past week, and which pages drove the most conversions. That five-minute check gives you everything you need to know about whether the site is working and where to focus if it is not.
Every site I build includes GA4 setup and form conversion tracking from day one. Book a strategy call if you want this set up correctly for your site.
