GA4 Setup Guide for Small Business Owners

Why GA4 Matters

Google Analytics 4 replaced Universal Analytics in July 2023. If you haven't switched yet, you're flying blind.

But here's the truth: most GA4 setups are done incorrectly, making the data useless.

This guide ensures you set it up right the first time.

Step 1: Create Your GA4 Property

1. Go to analytics.google.com
2. Click Admin (gear icon)
3. Click "Create Property"
4. Enter your business name and website URL
5. Select your industry and business size
6. Choose your reporting timezone and currency (GBP for UK)

Step 2: Install the Tracking Code

Option A: Google Tag Manager (Recommended)

1. Create a Google Tag Manager account
2. Add the GTM container code to your website
3. In GTM, create a new GA4 Configuration tag
4. Enter your Measurement ID (starts with G-)
5. Set trigger to "All Pages"
6. Publish the container

Option B: Direct Installation

1. In GA4, go to Data Streams
2. Click on your web stream
3. Copy the Google tag code
4. Paste in the section of every page

For Next.js Websites

Add to your layout.tsx or _app.tsx:

import Script from 'next/script'

<Script
  src={`https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX`}
  strategy="afterInteractive"
/>
<Script id="google-analytics" strategy="afterInteractive">
  {`
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'G-XXXXXXXXXX');
  `}
</Script>

Step 3: Verify Installation

1. Go to Reports → Realtime
2. Open your website in another tab
3. You should see yourself as an active user
4. If not, check the code installation

Step 4: Set Up Conversion Tracking

Essential Conversions for Small Businesses

Contact Form Submissions

1. Go to Events in GA4
2. Click "Create event"
3. Name it "form_submission"
4. Set conditions (page_location contains "thank-you")
5. Mark as conversion

Phone Calls

1. Use a call tracking service (CallRail, WhatConverts)
2. Or track clicks on phone links:
   • Event name: "phone_click"
   • Parameter: link_url contains "tel:"

Appointment Bookings

1. Track thank-you page views
2. Or track button clicks if using embedded calendars

Step 5: Connect Search Console

1. Go to Admin → Product Links → Search Console Links
2. Click "Link"
3. Select your Search Console property
4. This shows which keywords bring traffic

Step 6: Enable Google Signals

1. Go to Admin → Data Settings → Data Collection
2. Enable Google signals data collection

Step 7: Set Up Custom Audiences

Useful Audiences

High-Intent Visitors

• Visited pricing page
• Spent 2+ minutes on site
• Viewed 3+ pages

Potential Leads

• Visited contact page but didn't submit
• Started form but didn't complete

Past Converters

• Submitted a form
• Made a purchase

These audiences can be used for remarketing.

Key Metrics to Track

For All Businesses

Common Setup Mistakes

1. No conversion tracking - Without this, you can't measure success
2. Not filtering internal traffic - Your visits skew the data
3. Missing cross-domain tracking - If you use multiple domains
4. Ignoring data thresholds - GA4 hides data below certain volumes
5. Not setting up audiences - Limits your remarketing options

Filtering Internal Traffic

1. Go to Admin → Data Streams
2. Click your stream
3. Go to Configure tag settings → Define internal traffic
4. Add your office IP address
5. In Data Settings → Data Filters, create a filter for "internal"

Monthly Review Checklist

• Review traffic trends
• Identify top-performing pages
