Remove Unused CSS Rules
High Impact+3 points estimated
Why It Matters
43KB of unused CSS is blocking render and delaying FCP by 300ms.
How to Fix
Audit Bootstrap CSS usage and remove unused components - only 7.3% is actually used. Remove or defer FontAwesome CSS (99.6% unused) and load only required icons inline. Use tools like PurgeCSS or manual auditing to eliminate unused selectors.

What This Score Means
A score of 93 falls in the "Good" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website achieves a strong performance score of 93/100, indicating excellent overall optimization. The biggest opportunity for improvement is addressing render-blocking resources, particularly CSS and JavaScript files that are delaying the First Contentful Paint by over 1 second, preventing users from seeing content as quickly as possible. The site would benefit from removing 42 KiB of unused CSS (especially from Bootstrap and FontAwesome files) and optimizing image delivery to save an additional 48 KiB in download size. While the Largest Contentful Paint of 2.8 seconds is acceptable, implementing these optimizations could push this already high-performing site to near-perfect scores.
Other Optimization Recommendations
Defer Render-Blocking Resources
High Impact+2 points estimatedWhy It Matters:
Critical path is blocked by 1,090ms worth of CSS and JavaScript resources.
How to Fix:
Add 'defer' attribute to jQuery and vmsite.js scripts to prevent render blocking. Inline critical CSS from Bootstrap (only used portions) directly in HTML head. Load remaining CSS asynchronously using media='print' onload technique.
Optimize Image Dimensions
Medium Impact+1 points estimatedWhy It Matters:
Oversized images waste 48KB and delay LCP by 100ms unnecessarily.
How to Fix:
Resize banner.png from 1352x459 to 388x132 to match display size. Resize left-main.jpg from 896x599 to 388x259. Convert logo-pro.png to WebP format for 11KB savings. Add explicit width/height attributes to prevent layout shifts.
