The Hidden Cost of Cookie Banners

// TRADITIONAL: Client-side

// 1. Cookie Creation
document.cookie = "ga_id=GA1.2.1234567890.1625097600; expires=Thu, 31 Dec 2025 23:59:59 UTC; path=/; SameSite=Lax";

// 2. Local Storage for Tracking
localStorage.setItem('ga_session_id', 'session_' + Date.now());
localStorage.setItem('ga_client_id', generateClientId());

// 3. Data Collection (REQUIRES CONSENT)
if (hasConsent()) {
    gtag('config', 'GA_MEASUREMENT_ID', {
        'anonymize_ip': true,
        'cookie_update': true
    });

    // Track user behavior across sessions
    trackPageView();
    trackUserInteractions();
    buildUserProfile();
}

// PROBLEM: 12-15% user loss without consent

// GDPR METRICS: Server-side, no storage

// 1. Simple Script Inclusion (NO CONSENT NEEDED)
<script src="https:\/\/analytics.gdprmetrics.com\/analytics.js"
        data-site="YOUR_SITE_ID"></script>

// 2. Automatic Edge Processing
// - Request hits Cloudflare edge (EU location)
// - IP anonymized and used only for geolocation
// - User-Agent analyzed for device type
// - No persistent storage on user device

// 3. Server-side Aggregation
// - Data immediately aggregated
// - Individual points destroyed
// - Only anonymous statistics retained
// - 90-day automatic deletion

// RESULT: 100% data capture, 0% consent requirements
