Optimize Image Compression and Loading
High Impact+12 points estimated
Why It Matters
Poor image compression wastes 128 KiB and delays LCP by 800ms, directly impacting your largest contentful paint performance.
How to Fix
Increase compression levels for noise-orange.webp (66KB savings) and noise-beige.webp (51KB savings) using WordPress plugins like ShortPixel or Imagify. Add fetchpriority='high' attribute to your LCP background image in the home banner section. Consider using CSS background-image optimization or converting to an actual img element for better control.

AI Performance Analysis
This WordPress site has good performance with a score of 91/100, but there are still opportunities for improvement. The biggest issue is excessive unused CSS, with 98 KiB of wasted stylesheet code that's not being used on the page, particularly from the site's combined CSS files. Additionally, the site could benefit from better image compression, which could save 128 KiB and improve the Largest Contentful Paint time of 3.5 seconds by 0.8 seconds. The site is also experiencing forced reflows from JavaScript operations, which can cause performance hiccups during user interactions.
Other Optimization Recommendations
Eliminate Unused CSS Rules
High Impact+8 points estimatedWhy It Matters:
98 KiB of unused CSS (80-99% waste in stylesheets) increases download time and blocks rendering of critical above-the-fold content.
How to Fix:
Use WordPress plugins like Asset CleanUp or Autoptimize to remove unused CSS from your NitroPack-optimized stylesheets. Implement critical CSS extraction for above-the-fold content. Split your combined CSS files to load only necessary styles for each page template.
Fix Forced Reflow Issues
Medium Impact+6 points estimatedWhy It Matters:
JavaScript forced reflows consume 28ms of main thread time, potentially causing layout shifts and poor interaction responsiveness.
How to Fix:
Identify the unattributed JavaScript causing 27.7ms of reflow time using browser DevTools Performance tab. Batch DOM reads and writes together to avoid layout thrashing. Review your theme's JavaScript for properties like offsetWidth/offsetHeight queries and optimize the timing of these operations.
