Fix LCP Image Discovery
High Impact+20 points estimated
Why It Matters
Your LCP image has a 3.5 second resource load delay because it's not discoverable in the initial HTML document.
How to Fix
Move the hero image from being loaded via JavaScript or CSS to a direct <img> tag in your initial HTML. Add a preload link in the <head> for the hero image with fetchpriority='high'. Ensure the image source is available immediately when the HTML is parsed, not after JavaScript execution.

AI Performance Analysis
This website has poor performance with a score of 61/100, primarily due to extremely slow loading times that hurt user experience. The biggest issue is the Largest Contentful Paint taking 7.5 seconds, which is mainly caused by a 3.5-second delay in loading the main hero image, along with unused JavaScript that's adding another 1.4 seconds of delay. The site is also loading 532KB of unnecessary JavaScript code and 12KB of unused CSS, plus web fonts are blocking text display for 650ms. To improve performance significantly, focus first on optimizing the hero image loading and removing unused JavaScript, which together could reduce load times by several seconds and boost the performance score substantially.
Other Optimization Recommendations
Eliminate Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
532 KiB of unused JavaScript is blocking LCP by 1.35 seconds and severely impacting performance.
How to Fix:
Audit your JavaScript bundles to identify unused code in the main chunks. Implement code splitting to load only necessary JavaScript per page. Remove or lazy-load Google Tag Manager and other tracking scripts until after page interactive. Consider tree-shaking to eliminate dead code from your build process.
Optimize Font Loading Strategy
Medium Impact+8 points estimatedWhy It Matters:
Font loading delays are causing 650ms delay to First Contentful Paint and creating invisible text periods.
How to Fix:
Add font-display: swap to your custom font declarations (SofiaPro-Light and Mandrel Norm Regular). Implement font metric overrides to reduce layout shifts when fonts load. Consider using a system font stack as fallback to improve perceived performance.
