Reduce Unused JavaScript Payloads
High Impact+10 points estimated
Why It Matters
446 KiB of unused JavaScript is blocking the main thread and delaying Time to Interactive by 2.25 seconds.
How to Fix
Remove or defer the Shopify Chat widget (136KB unused) if not essential. Optimize Google Analytics implementation by using gtag with selective event tracking. Consider lazy-loading third-party scripts like Facebook Pixel until user interaction occurs.

What This Score Means
A score of 48 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 store has poor performance with a score of 48/100, indicating significant user experience issues. The biggest problem is extremely slow interactivity - it takes 24.4 seconds for the page to become fully interactive, which will frustrate customers and hurt conversions. The main culprits are excessive JavaScript execution (over 3.7 seconds of main thread blocking), render-blocking CSS files that delay initial page rendering, and oversized images that could be compressed by 418 KB. Addressing these JavaScript and CSS blocking issues, along with optimizing images, could potentially improve the performance score by 30+ points and dramatically reduce page load times.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+15 points estimatedWhy It Matters:
Critical CSS files are blocking initial page render, causing a 980ms delay in First Contentful Paint.
How to Fix:
In your Shopify theme's layout/theme.liquid file, inline critical CSS for above-the-fold content directly in <style> tags. Move non-critical CSS like component-discounts.css and theme-mood4.css to load asynchronously using rel='preload' as='style' onload="this.onload=null;this.rel='stylesheet'".
Remove Lazy Loading from LCP Image
High Impact+12 points estimatedWhy It Matters:
The hero banner image has loading='lazy' which delays LCP by preventing immediate image discovery and loading.
How to Fix:
Edit your slideshow template (sections/slideshow.liquid) and remove loading='lazy' from the first slide image. Add fetchpriority='high' to prioritize loading. Ensure the hero image is discoverable in the initial HTML without JavaScript.
