Bounce Rate

Bounce rate represents the percentage of single-page sessions where users leave a website without any interaction. This metric helps evaluate user engagement, content relevance, and overall website effectiveness.

Understanding Bounce Rate

1. Definition and Calculation

// Basic Bounce Rate Formula
Bounce Rate = (Single-page Sessions / Total Sessions) × 100

// Example Google Analytics Implementation
gtag('config', 'UA-XXXXXXXX-X', {
  'custom_map': {
    'metric1': 'bounce_rate'
  }
});

2. Industry Averages

• Blog sites: 70-90%
• E-commerce: 20-45%
• Landing pages: 60-80%
• B2B sites: 25-55%
• Service sites: 30-60%
• Content sites: 40-70%
• Retail sites: 20-40%

Measurement Methods

1. Google Analytics Setup

// Enhanced Bounce Rate Tracking
gtag('config', 'UA-XXXXXXXX-X', {
  'site_speed_sample_rate': 100,
  'session_timeout': 1800,
  'pageview_timeout': 60
});

// Event-Adjusted Bounce Rate
gtag('event', 'engagement', {
  'event_category': 'User Interaction',
  'event_label': 'Scroll Depth',
  'non_interaction': true
});

2. Custom Tracking

// Time-Based Bounce Rate
setTimeout(function() {
  if (!hasInteracted) {
    gtag('event', 'time_on_page', {
      'event_category': 'Engagement',
      'event_label': '30 seconds',
      'non_interaction': true
    });
  }
}, 30000);

// Scroll Depth Tracking
window.addEventListener('scroll', function() {
  let scrollDepth = (window.pageYOffset / document.documentElement.scrollHeight) * 100;
  if (scrollDepth > 25 && !scrollTracked) {
    gtag('event', 'scroll_depth', {
      'event_category': 'Engagement',
      'event_label': '25%',
      'non_interaction': true
    });
    scrollTracked = true;
  }
});
