Project summary

Overview

This project focused on optimizing the performance of an APK-based website that was facing slow loading speeds, particularly on mobile devices. The primary objective was to improve Core Web Vitals, achieve high PageSpeed scores, and enhance overall user experience to support better rankings and engagement.

Key Problems

The website had several performance bottlenecks:

  • Slow mobile loading speed
  • Render-blocking CSS and JavaScript
  • Unoptimized images increasing load time
  • Poor Core Web Vitals affecting SEO
  • High dependency on heavy scripts and third-party resources

These issues were negatively impacting user retention, rankings, and monetization potential.

Optimization Strategy

A comprehensive technical optimization plan was executed:

1. Frontend Performance Optimization
  • Minified and combined CSS, JavaScript, and HTML
  • Removed unused CSS and deferred non-critical JS
  • Implemented lazy loading for images and media
  • Optimized critical rendering path
  •  
2. Image Optimization
  • Converted images to WebP format
  • Applied compression without quality loss
  • Implemented responsive image sizes
  •  
3. Core Web Vitals Optimization
  • Reduced Largest Contentful Paint (LCP)
  • Eliminated Total Blocking Time (TBT)
  • Stabilized layout to achieve zero Cumulative Layout Shift (CLS)
  •  
4. Server & Caching Enhancements
  • Enabled browser caching
  • Implemented server-side caching
  • Optimized database and reduced server response time
5. Third-Party Script Optimization
  • Delayed unnecessary scripts
  • Reduced external dependencies
  • Optimized script loading behavior
