Analytics Setup
Track everything. If you can't measure it, you can't improve it.
GA4 (Google Analytics 4)
Basic Installation
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-XXXXXXXXXX');
</script>
Custom Events for Funnels
document.querySelectorAll('.cta-primary').forEach(btn => {
btn.addEventListener('click', () => {
gtag('event', 'cta_click', {
event_category: 'funnel',
event_label: btn.textContent.trim(),
page_title: document.title
});
});
});
document.querySelectorAll('form').forEach(form => {
form.addEventListener('submit', () => {
gtag('event', 'form_submit', {
event_category: 'funnel',
event_label: form.getAttribute('name') || 'unnamed',
page_title: document.title
});
});
});
let scrollMarks = [25, 50, 75, 100];
window.addEventListener('scroll', () => {
const percent = Math.round((window.scrollY / (document.body.scrollHeight - window.innerHeight)) * 100);
scrollMarks = scrollMarks.filter(mark => {
if (percent >= mark) {
gtag('event', 'scroll_depth', { event_category: 'engagement', event_label: mark + '%' });
return false;
}
return true;
});
});
Meta Pixel (Facebook)
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', 'YOUR_PIXEL_ID');
fbq('track', 'PageView');
</script>
Key Events to Track
fbq('track', 'Lead', { content_name: 'Free Guide Opt-In' });
fbq('track', 'CompleteRegistration', { content_name: 'Webinar' });
fbq('track', 'Purchase', { value: 297, currency: 'USD' });
fbq('track', 'AddToCart', { value: 47, currency: 'USD' });
UTM Parameter Handling
Standard UTM Parameters
?utm_source=facebook
&utm_medium=cpc
&utm_campaign=webinar-launch
&utm_content=headline-a
&utm_term=marketing-course
Capture and Store UTMs
const params = new URLSearchParams(window.location.search);
const utmKeys = ['utm_source', 'utm_medium', 'utm_campaign', 'utm_content', 'utm_term'];
const utms = {};
utmKeys.forEach(key => {
const val = params.get(key);
if (val) utms[key] = val;
});
if (Object.keys(utms).length > 0) {
localStorage.setItem('funnel_utms', JSON.stringify(utms));
}
document.querySelectorAll('form').forEach(form => {
const stored = JSON.parse(localStorage.getItem('funnel_utms') || '{}');
Object.entries(stored).forEach(([key, val]) => {
const input = document.createElement('input');
input.type = 'hidden';
input.name = key;
input.value = val;
form.appendChild(input);
});
});
