Remove Unused JavaScript Code
High Impact+2 points estimated
Why It Matters
55KB of unused JavaScript is delaying both FCP and LCP by 300ms each.
How to Fix
Analyze your bundle with webpack-bundle-analyzer or similar tools to identify unused code. Implement code splitting to load only necessary JavaScript per route. Use tree shaking to eliminate dead code and consider lazy loading non-critical components.

What This Score Means
A score of 93 falls in the "Good" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website achieves a strong performance score of 93/100, indicating excellent overall optimization. However, the biggest issue is excessive unused JavaScript code, which is wasting 54 KiB of data and causing a 300ms delay in both First Contentful Paint and Largest Contentful Paint metrics. The main JavaScript file contains about 30% unused code that could be removed or split into smaller chunks that load only when needed. Additional improvements could come from fixing render-blocking CSS resources and extending cache lifetimes for static assets, but addressing the unused JavaScript would provide the most significant performance boost.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+3 points estimatedWhy It Matters:
CSS is blocking initial render and delaying LCP by 300ms.
How to Fix:
Inline critical CSS directly in the HTML head for above-the-fold content. Load the remaining CSS asynchronously using media='print' onload='this.media="all"' or defer with JavaScript. Split your CSS bundle to prioritize critical styles first.
Fix Forced Reflow Issues
Medium Impact+1 point estimatedWhy It Matters:
JavaScript is causing 53ms of forced reflows that block the main thread.
How to Fix:
Batch DOM reads and writes to avoid layout thrashing. Cache geometric property values instead of repeatedly querying them. Move DOM measurements outside of loops and use requestAnimationFrame for animation-related layout changes.
