Reduce Render-Blocking Resources

High Impact+18 points estimated

Why It Matters

CSS and JavaScript files are blocking initial page render for 3,090ms, significantly delaying First Contentful Paint.

How to Fix

Inline critical CSS for above-the-fold content and defer non-critical stylesheets using media='print' onload technique. Move non-essential JavaScript to load after page interactive. Preload key resources like css_CmtRY5lhrSr89MQOsLtE1cRBz1w5wuH8jIJGMk3kK7U2.css earlier in the document head.

0Poor

What This Score Means

A score of 30 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 Estée Lauder mobile site has severe performance issues with a critically low score of 30/100. The biggest problem is excessive page redirects that waste over 2 seconds before the page even starts loading, combined with massive amounts of unused JavaScript (1.2MB) and CSS (265KB) that block rendering for over 3 seconds. The site takes an extremely slow 37 seconds to become interactive and 7.5 seconds just to show the main content, primarily due to duplicate JavaScript modules across 25+ service bundles and oversized images that are 2-3 times larger than needed. Eliminating the redirect chain, removing unused code, and properly sizing images could easily improve the performance score by 40+ points and dramatically reduce load times.

Other Optimization Recommendations

Eliminate Duplicate JavaScript Modules

High Impact+25 points estimated

Why It Matters:

55 KiB of duplicate JavaScript across multiple service bundles is increasing network overhead and blocking page rendering.

How to Fix:

Implement module federation or shared chunks in your webpack configuration to eliminate duplicated dependencies like @estee/elc-service and @estee/elc-universal-utils. Create a common vendor bundle for shared utilities. Review your micro-frontend architecture to prevent loading duplicate modules across different services.

Optimize Image Delivery and Sizing

High Impact+20 points estimated

Why It Matters:

Images are oversized by 654 KiB and delaying LCP by 300ms due to serving 2000x2000 images for 695x695 display areas.

How to Fix:

Implement responsive images using srcset with multiple image sizes (640w, 960w, 1280w, 2000w). Configure your CDN to automatically serve appropriately sized images based on device pixel ratio. Use next-gen formats like WebP with fallbacks for product images.
