Fix LCP Image Loading
High Impact+2 points estimated
Why It Matters
The hero image uses lazy loading and lacks priority hints, potentially delaying LCP and creating suboptimal user experience.
How to Fix
Remove loading='lazy' from the hero image and add fetchpriority='high' attribute. Replace the CSS calc() width value with explicit pixel dimensions. Preload the hero image using <link rel='preload' as='image'> in the HTML head to start downloading immediately.

AI Performance Analysis
This website achieves a strong performance score of 94/100, indicating excellent optimization overall. The biggest issue affecting load times is render-blocking resources (CSS and JavaScript files) that delay the initial page display by an estimated 1.1 seconds, particularly impacting First Contentful Paint. The main image on the page is also problematic - it's lazy-loaded when it should load immediately since it's the largest visual element, and it's oversized for its display dimensions, wasting 41 KB of bandwidth. Quick wins include removing lazy-loading from the hero image, adding fetchpriority="high" to prioritize it, properly sizing the image, and deferring non-critical JavaScript to eliminate render-blocking behavior.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+3 points estimatedWhy It Matters:
JavaScript and CSS files are blocking initial render, delaying FCP by 1.1 seconds and creating a poor loading experience.
How to Fix:
Move the hexfilter.js and Brevo popup script to load after page content using async or defer attributes. Inline critical CSS for above-the-fold content and load the full stylesheet asynchronously. Consider removing non-essential third-party scripts from the critical path.
Optimize Font Loading Strategy
Medium Impact+1 point estimatedWhy It Matters:
Custom fonts are causing 180ms delay in text visibility, hurting First Contentful Paint and user experience.
How to Fix:
Add font-display: swap to your @font-face declarations to show fallback text immediately. Preload critical fonts using <link rel='preload' as='font'> tags. Consider using font metric overrides in CSS to reduce layout shift when custom fonts load.
