Reduce JavaScript Bundle Size

High Impact+25 points estimated

Why It Matters

JavaScript execution blocks the main thread for 9.5 seconds and causes 5,070ms of Total Blocking Time, severely impacting LCP and user interactions.

How to Fix

Implement code splitting to break the large 195KB unused JavaScript chunks into smaller, on-demand bundles. Remove or defer third-party scripts like Facebook Pixel and Ada chat widget until after page load. Use tree-shaking to eliminate 1,729KB of unused JavaScript code.

What This Score Means

A score of 29 falls in the "Poor" 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 Kavehome product page has severe performance issues with a critically low score of 29/100. The biggest problem is excessive JavaScript execution that's blocking the main thread for over 13 seconds, causing a devastating Total Blocking Time of 5+ seconds and making the page essentially unusable until it fully loads. The site is also suffering from massive amounts of unused JavaScript (1,729 KiB wasted) and oversized images that could be reduced by 1,383 KiB. Immediate priorities should be reducing JavaScript payloads, removing unused code, and implementing properly sized responsive images, which together could improve the score by 40+ points and dramatically enhance user experience.

Other Optimization Recommendations

Optimize Image Delivery

High Impact+15 points estimated

Why It Matters:

Oversized images waste 1,383KB of bandwidth and contribute to the poor 13.9s LCP time.

How to Fix:

Resize product gallery images to match their display dimensions (412x515px instead of 1800x2250px). Implement responsive images with proper srcset attributes. Use next-gen formats like WebP through your CDN's auto-format feature.

Eliminate Render-Blocking CSS

Medium Impact+12 points estimated

Why It Matters:

CSS files are blocking First Contentful Paint by 2.5 seconds, delaying when users see content.

How to Fix:

Inline critical above-the-fold CSS directly in the HTML head. Defer non-critical CSS using media='print' onload technique or loadCSS library. Remove 26KB of unused CSS rules, especially from the 0qg1muh_dzw7y.css file that's 95% unused.
