Remove Unused CSS Rules
High Impact+3 points estimated
Why It Matters
40KB of unused CSS is delaying both FCP and LCP by 150ms, directly impacting Core Web Vitals.
How to Fix
Use PurgeCSS or UnCSS to remove unused styles from the LiteSpeed cached CSS file. Configure your CSS optimization plugin to only load critical above-the-fold CSS inline and defer the rest. Consider splitting CSS by page templates to reduce unused rules.

AI Performance Analysis
This website has excellent performance with a score of 99/100, indicating very fast loading times for users. The biggest opportunity for improvement is reducing unused CSS, which could save 40 KiB and potentially improve loading times by 150ms. The site also has a minor image optimization issue where one banner image is larger than necessary for its display size, wasting about 17 KiB of bandwidth. Additionally, there are some technical issues with font display settings and forced reflows that could be optimized, but these have minimal impact given the already outstanding performance score.
Other Optimization Recommendations

Medium Impact+1 point estimatedWhy It Matters:
The banner image is 17KB larger than needed for its display size, wasting bandwidth unnecessarily.
How to Fix:
Resize the banner image from 1370x180px to match its displayed dimensions of 721x95px. Use responsive images with srcset to serve appropriately sized images for different screen sizes. Configure your image optimization plugin to automatically generate properly sized variants.
Fix Font Display Strategy
Low Impact+1 point estimatedWhy It Matters:
Poor font loading strategy is causing 20ms delays and potential layout shifts during text rendering.
How to Fix:
Add font-display: swap to your custom font declarations in CSS to ensure text remains visible during font load. Consider using font-display: optional for icon fonts like fl-icons.woff2. Implement font preloading for critical fonts to reduce render blocking time.
