  <source srcset="hero.avif" type="image/avif">  
  <img src="hero.jpg" alt="Hero image" loading="lazy">
</picture>

<style>
/* Critical CSS for above-fold content */
.hero { display: flex; align-items: center; }
.cta-button { background: #007cba; color: white; }
</style>

<!-- Async load non-critical CSS -->
<link rel="preload" href="main.css" as="style" onload="this.onload=null;this.rel='stylesheet'">

  document.querySelector('.hero-headline').textContent = 
    'Gevonden via Google- Perfect! Wij helpen je website nog zichtbaarder maken.';
} else if (source === 'facebook') {
  document.querySelector('.hero-headline').textContent = 
    'Welkom Facebook bezoeker! Laten we jouw social media traffic omzetten in klanten.';
}

navigator.geolocation.getCurrentPosition(function(position) {
  // Get user city/region
  fetch(`/api/location/${position.coords.latitude},${position.coords.longitude}`)
    .then(response => response.json())
    .then(data => {
      document.querySelector('.location-cta').textContent = 
        `Webdesign specialisten in ${data.city}`;
    });
});

Behavioral Personalization

Return Visitor Treatment:

// Different message for return visitors
if (localStorage.getItem('previousVisit')) {

Measuring CRO Success

Key CRO Metrics

Primary Metrics:

CRO ROI Calculation

Example ROI Calculation:

Current Situation:
- 1000 visitors/month

- 1000 visitors/month  
- 3% conversion rate = 30 customers
- €500 average customer value = €15,000 revenue

Additional Revenue: €5,000/month = €60,000/year
CRO Investment: €10,000
ROI: 500% first year
