Medium Impact+12 points estimated
Why It Matters
Render-blocking CSS is delaying First Contentful Paint by 150ms and slowing initial page rendering.
How to Fix
In your theme's layout/theme.liquid file, inline critical CSS for above-the-fold content. Move the accelerated checkout CSS to load asynchronously using media='print' onload='this.media="all"'. Defer non-critical stylesheets like section-specific CSS files until after page load using Shopify's asset_url with async loading.

What This Score Means
A score of 63 falls in the "Needs Improvement" 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 poor performance issues with a score of 63/100. The biggest problem is extremely slow loading times, with the Largest Contentful Paint taking 5.1 seconds and the site becoming fully interactive only after 15.4 seconds. The main culprits are unoptimized images that could save 127 KiB and improve loading by nearly half a second, plus excessive unused JavaScript (203 KiB) and CSS (18 KiB) that's bloating the site. Compressing and properly sizing images, removing unused code, and addressing the complex network dependency chains could dramatically improve performance and user experience.
Other Optimization Recommendations
Optimize Image Delivery and Compression
High Impact+25 points estimatedWhy It Matters:
Poor image optimization is causing a 450ms LCP delay and wasting 127 KiB of bandwidth.
How to Fix:
In your Shopify admin, use the built-in image optimization features or install TinyIMG app. Resize the hero image to match its displayed dimensions (588x395 instead of 700x470). Increase compression on the main product images which are currently under-optimized. Enable Shopify's automatic WebP conversion in your theme settings.
Reduce JavaScript Bundle Size
High Impact+18 points estimatedWhy It Matters:
203 KiB of unused JavaScript is bloating your site and 357ms of Total Blocking Time is delaying interactivity.
How to Fix:
Remove unused Google Analytics tracking codes (you have two GTM scripts). Update your Klaviyo integration to use modern JavaScript without legacy polyfills, saving 18 KiB. In your Shopify theme, audit vendor.js and remove unused libraries. Consider code splitting for non-critical features using Shopify's Script Tag API.
