Performance Monitoring

Track and improve your website's speed, loading times, and performance metrics to deliver the best possible user experience.

Why Website Performance Matters

Website performance directly impacts user experience, search rankings, and business success. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load. Google also uses page speed as a ranking factor, meaning slow websites rank lower in search results.

Our performance monitoring uses Google Lighthouse in a controlled lab environment (synthetic mobile and desktop runs) so you get consistent, repeatable scores. Your dashboard shows category scores (Performance, Accessibility, Best Practices, SEO), key timing metrics that align with Core Web Vitals, and human-readable fix guidance—not a single mystery number.

What We Monitor

Each scan surfaces Lighthouse-driven signals and the metrics we highlight in your report:

• Lighthouse category scores (0–100): Performance, Accessibility, Best Practices, and SEO—separately for mobile and desktop lab runs
• Largest Contentful Paint (LCP): When the main visible content finishes rendering (Core Web Vital)
• Cumulative Layout Shift (CLS): Visual stability during load (Core Web Vital)
• First Contentful Paint (FCP): When the first text or image is painted
• Total Blocking Time (TBT): Main-thread blocking during load—a strong lab companion to interactivity (Google’s field metric INP has largely replaced FID for real users)
• Speed Index: How quickly content appears in the viewport during load
• Time to Interactive (TTI): Still reported by Lighthouse in the underlying audit data where available
• Plus: Render-blocking resources, image weight, caching, compression, and third-party impact—surfaced through Lighthouse audits and your issue list

Core Web Vitals & lab vs. field data

Google’s Core Web Vitals (LCP, INP, CLS) are primarily measured from real users (for example, the Chrome User Experience Report). COTGI’s dashboard focuses on lab measurements from Lighthouse: we show LCP and CLS directly, and use Total Blocking Time in the lab as a practical stand-in for interactivity while your page loads. Lab and field numbers often differ—that’s expected.

• Good targets (Google): LCP under 2.5s, INP under 200ms, CLS under 0.1 for real-user data
• In your COTGI report: Compare mobile vs. desktop lab results, use the built-in metric help modals, and follow prioritized fix recommendations

Performance Optimization Recommendations

Our analysis doesn't just identify problems—it provides specific recommendations to improve performance:

• Image optimization and compression strategies
• CSS and JavaScript minification and bundling
• Lazy loading implementation for images and resources
• Browser caching configuration
• CDN setup and configuration
• Server optimization recommendations
• Code splitting and resource prioritization
• Third-party script optimization

Continuous Monitoring

For paid subscribers, we offer continuous performance monitoring that tracks your website's speed over time. Set up automated scans to monitor performance trends, receive alerts when performance degrades, and track improvements after implementing optimizations.

Impact on Business

Improving website performance has measurable business benefits:

• Higher conversion rates from faster-loading pages
• Better search engine rankings from improved Core Web Vitals
• Reduced bounce rates as users stay on faster sites
• Improved mobile experience for on-the-go users
• Lower server costs from optimized resource usage
