Eliminate Render Blocking CSS
High Impact+25 points estimated
Why It Matters
CSS files are blocking initial page render, delaying FCP by 2.95 seconds and contributing to the poor 55 performance score.
How to Fix
In your Shopify theme, defer non-critical CSS by adding media='print' onload="this.media='all'" to theme.scss.css and vendor.min.css links. Move critical above-the-fold styles inline in the <head>. Remove the completely unused storeifyapps-formbuilder-styles.css (100% unused) or load it conditionally only when the form is present.
0Needs Improvement
What This Score Means
A score of 55 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 with a score of 55/100, indicating significant issues that hurt user experience. The biggest problem is excessive unused CSS and JavaScript that's blocking the page from rendering quickly - your First Contentful Paint takes 7.4 seconds and Largest Contentful Paint takes a devastating 12.8 seconds, both well beyond acceptable limits. The main culprits are bloated CSS files (87KB of unused styles), render-blocking stylesheets that delay page rendering by nearly 3 seconds, and 341KB of unused JavaScript code that's unnecessarily slowing down your site. Cleaning up these unused resources, optimizing your main banner image (which is oversized), and implementing proper resource loading strategies could dramatically improve your performance score and cut loading times in half.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+20 points estimatedWhy It Matters:
341 KiB of unused JavaScript is slowing LCP by 2.15 seconds and wasting bandwidth on mobile users.
How to Fix:
Audit the storeifyapps-formbuilder-script.js (80% unused) and remove if the form builder isn't essential. Split vendor.js into critical and non-critical bundles, deferring non-essential features. Remove unused Google Analytics features or switch to gtag with selective event tracking to reduce the 59KB waste.
Optimize LCP Hero Image
Medium Impact+8 points estimatedWhy It Matters:
The main banner image is oversized (1920x720 vs 613x230 display), wasting 155KB and not discoverable for preloading.
How to Fix:
Create responsive image variants in Shopify admin for your hero banner at 613w, 1226w, and 1839w sizes. Add fetchpriority='high' and preload the hero image in the document <head>. Use Shopify's responsive image liquid tags to serve appropriately sized images based on viewport.
