Eliminate Forced Reflow Issues
High Impact+25 points estimated
Why It Matters
Forced reflows are consuming 430ms of main thread time, directly blocking user interactions and increasing Total Blocking Time.
How to Fix
Audit bd-collection-featured-slider.js and theme.js which are causing 90ms+ reflows each. Batch DOM reads before writes, cache layout properties, and use CSS transforms instead of geometric property changes. Consider replacing Swiper.js with lighter alternatives or optimize initialization timing.

What This Score Means
A score of 36 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 Shopify site has severe performance issues with a score of only 36/100. The biggest problem is extremely slow page loading, with users waiting over 28 seconds to see the main content (Largest Contentful Paint) and 36 seconds for the page to become fully interactive. The primary culprit is JavaScript causing "forced reflows" - where the browser repeatedly recalculates page layout, wasting over 400ms of processing time from scripts like collection sliders, GSAP animations, and Swiper components. Additionally, the site loads 465 KB of unused JavaScript and oversized images that could be 2.2 MB smaller, creating a frustrating user experience that likely drives visitors away before the page even finishes loading.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+20 points estimatedWhy It Matters:
465 KiB of unused JavaScript is delaying LCP by 1.65 seconds and wasting bandwidth on mobile connections.
How to Fix:
Remove or defer Tolstoy video widget (175KB unused) and Appstle subscription scripts (49KB unused) from initial page load. Use Shopify's Script Tag API to load these only when needed. Split Google Analytics code and load asynchronously after page interactive.
Optimize Image Delivery Strategy
High Impact+15 points estimatedWhy It Matters:
2.2MB of oversized images are slowing LCP by 300ms, particularly the hero image and product collection thumbnails.
How to Fix:
Use Shopify's responsive image URLs with proper width parameters matching display sizes. Add fetchpriority='high' to LCP hero image. Implement lazy loading for product cards below fold using Shopify's native lazy loading. Compress images further using Shopify's built-in optimization.
