High Impact+10 points estimated
Why It Matters
Six web fonts create 1025ms dependency chain blocking content rendering.
How to Fix
Add preload links for critical fonts (Lora-600, Cormorant-400) in HTML head. Combine multiple font weights into single variable fonts. Use font-display: swap on all @font-face declarations. Remove unused font weights like IBM Plex Mono variants.

AI Performance Analysis
This website has concerning performance issues with a score of 70/100, primarily due to an extremely slow Largest Contentful Paint of 5.5 seconds - well above the recommended 2.5 seconds. The biggest culprits are unused JavaScript from Google Analytics and Tag Manager that's wasting 127KB of data and delaying page load by 750ms, plus an oversized portrait image that could be reduced by 25KB. Additionally, the site is loading 6 different font files in a chain that takes over 1 second to complete, further slowing down the initial page render. Removing unused tracking code, optimizing the portrait image for its display size, and implementing font preloading could dramatically improve the user experience and Core Web Vitals scores.
Other Optimization Recommendations
Reduce Unused JavaScript Files
High Impact+12 points estimatedWhy It Matters:
Google Analytics/Tag Manager scripts waste 127 KiB and delay LCP by 750ms.
How to Fix:
Move Google Analytics to load after user interaction using gtag delay plugin. Remove unused GTM triggers and tags. Consider switching to Google Analytics 4 measurement protocol for essential tracking only. Use Partytown to run tracking scripts in a web worker.
Optimize Portrait Image Delivery
Medium Impact+5 points estimatedWhy It Matters:
Portrait image is 25KB larger than needed for its display size.
How to Fix:
Resize portrait.jpg to actual display dimensions (282x373px for mobile). Convert to WebP format for additional 30% compression. Ensure srcset serves correctly sized images. Consider using CSS object-fit instead of oversized images.
