Fix Massive Layout Shifts
High Impact+30 points estimated
Why It Matters
Your CLS score of 0.839 is extremely poor due to web fonts and unsized images causing content to jump during page load.
How to Fix
Add explicit width and height attributes to all product images in your Shopify theme templates. Preload critical fonts (Merriweather, Poppins) in your theme.liquid file using <link rel='preload'> tags. Add font-display: swap to all @font-face declarations to prevent invisible text during font load.
0Poor
What This Score Means
A score of 0 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 0/100, primarily caused by massive layout shifts (0.84 CLS score) that make the page visually unstable as it loads. The biggest culprit is web fonts loading late and causing text to reflow, combined with unsized images that shift content around when they load. The site is also bloated with a 5.5MB payload mostly from oversized font files (over 1MB total), render-blocking CSS files, and unoptimized product images that could be compressed and properly sized. Fixing the layout shifts by setting explicit image dimensions, optimizing font loading with font-display: swap, and compressing images could dramatically improve the user experience and Core Web Vitals scores.
Other Optimization Recommendations
Optimize Product Images
High Impact+25 points estimatedWhy It Matters:
Product images are oversized and poorly compressed, wasting 304 KiB and potentially delaying LCP.
How to Fix:
Use Shopify's responsive image features with srcset for different screen sizes. Compress product images to 80-85% quality using Shopify's built-in image optimization or apps like TinyIMG. Serve images in WebP format by updating your product image URLs to include format=webp parameter.
Eliminate Forced Reflows
Medium Impact+15 points estimatedWhy It Matters:
PageFly page builder is causing 294ms of forced reflows, blocking the main thread and degrading user experience.
How to Fix:
Review PageFly elements that query DOM properties after style changes. Move geometric property reads (offsetWidth, getBoundingClientRect) before DOM modifications. Consider replacing PageFly with native Shopify sections for better performance, or contact PageFly support about the reflow issues in their helper scripts.
