Implement Efficient Cache Headers
Medium Impact+8 points estimated
Why It Matters
Poor caching wastes 170 KiB on repeat visits and delays LCP by 650ms unnecessarily.
How to Fix
Set cache-control headers to 1 year for static assets like Firebase auth scripts. Configure CDN caching for analytics scripts with appropriate versioning. Add immutable cache headers for fingerprinted JavaScript bundles.

AI Performance Analysis
This payment checkout page has poor performance with a score of 65/100, primarily due to excessive JavaScript blocking the main thread for 2.5 seconds. The biggest issue is an extremely slow Largest Contentful Paint of 12 seconds, caused by heavy JavaScript execution (1.6 seconds) and nearly 600KB of unused JavaScript code, particularly from reCAPTCHA scripts. The site could see dramatic improvements by removing unused JavaScript, optimizing the main banner image loading, and implementing better caching strategies which could save 170KB in repeat visits. These optimizations would significantly reduce the current 13.2-second Time to Interactive and create a much smoother checkout experience for users.
Other Optimization Recommendations
Reduce Unused JavaScript Payloads
High Impact+25 points estimatedWhy It Matters:
586 KiB of unused JavaScript delays LCP by 4.8 seconds and blocks main thread execution.
How to Fix:
Split the main bundle to load only critical components initially. Lazy load reCAPTCHA until user interaction is needed. Use dynamic imports for non-essential features like analytics and tracking scripts.
Optimize Script Execution Time
High Impact+20 points estimatedWhy It Matters:
JavaScript execution takes 1.6 seconds and blocks the main thread, preventing user interactions.
How to Fix:
Break down large script evaluation tasks using requestIdleCallback or setTimeout to yield control. Optimize the main app bundle by removing unnecessary dependencies. Consider using a Web Worker for heavy computations in analytics scripts.
