Optimize LCP Image Discovery
High Impact+15 points estimated
Why It Matters
Your LCP image isn't discoverable in initial HTML and lacks priority hint, delaying page loads significantly.
How to Fix
Add fetchpriority='high' to your LCP image (Acrylic Storefront Sign). Move the image source directly into HTML instead of loading via JavaScript. Remove lazy loading from above-the-fold images in your Shopify theme templates.

What This Score Means
A score of 41 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 critically low score of 41/100. The biggest problem is oversized images that are much larger than their display dimensions, wasting over 3MB of bandwidth and delaying your Largest Contentful Paint by 5.2 seconds. Your site also suffers from excessive JavaScript execution (2.8 seconds) and over 1MB of unused JavaScript from tracking scripts like Google Analytics. Optimizing image sizes, removing unused JavaScript, and deferring non-essential scripts could dramatically improve your score by 30+ points and reduce load times from 24 seconds to under 5 seconds.
Other Optimization Recommendations
Reduce Unused JavaScript Payloads
High Impact+18 points estimatedWhy It Matters:
Over 1,128 KiB of unused JavaScript is delaying LCP by 3.45 seconds and blocking user interactions.
How to Fix:
Remove or defer Google Tag Manager scripts until after page load using Shopify's Script Tag API. Audit third-party analytics scripts and load them asynchronously. Consider replacing multiple GTM containers with a single implementation to reduce redundancy.
Implement Responsive Image Sizing
High Impact+12 points estimatedWhy It Matters:
Images are 10x larger than needed for display, wasting 3,316 KiB and delaying LCP by 5.2 seconds.
How to Fix:
Use Shopify's responsive image system with proper srcset attributes. Resize the banner image from 4108x4340 to match display size of 412x435. Configure your theme to generate multiple image sizes automatically using Shopify's image transformation API.
