Optimize Hero Image Delivery
Medium Impact+8 points estimated
Why It Matters
The main content image is oversized by 33KB, causing unnecessary bandwidth usage and slower LCP.
How to Fix
In Shopify admin, replace the current 900x311px image with a properly sized 378x131px version for mobile. Use Shopify's responsive image URLs with ?width=378 parameter. Add multiple srcset sizes for different breakpoints using Shopify's image transformation API.

AI Performance Analysis
This Shopify site has poor performance with a score of 68/100, primarily due to extremely slow loading times that hurt user experience. The biggest problem is the Largest Contentful Paint taking 10 seconds, caused by an oversized image that's using lazy loading when it shouldn't be and lacks proper priority hints. The site is also bloated with 308 KiB of unused JavaScript from Google Analytics and 44 KiB of unused CSS, which delays interactivity by over 11 seconds. Quick wins include removing lazy loading from the main image, adding fetchpriority="high" to it, properly sizing images for their display dimensions, and deferring non-critical JavaScript to dramatically improve loading speeds.
Other Optimization Recommendations
Fix LCP Image Loading Issues
High Impact+15 points estimatedWhy It Matters:
The LCP image uses loading='lazy' and lacks fetchpriority='high', delaying page load by several seconds.
How to Fix:
Remove loading='lazy' from the hero image (rocker-plate-installation-guide.webp). Add fetchpriority='high' attribute to prioritize loading. In Shopify theme editor, locate the image element and update the liquid template to exclude lazy loading for above-the-fold images.
Reduce Unused JavaScript Payload
High Impact+12 points estimatedWhy It Matters:
Google Analytics scripts contain 308 KiB of unused code, slowing LCP by 1.9 seconds.
How to Fix:
Implement Google Tag Manager to load analytics conditionally. Use Shopify's Web Pixels API instead of multiple gtag implementations. Consider using Partytown to run analytics in a web worker, reducing main thread blocking.
