High Impact+18 points estimated
Why It Matters
CSS files are blocking page rendering for 3,050ms, preventing users from seeing content quickly.
How to Fix
Install WP Rocket or LiteSpeed Cache to inline critical CSS and defer non-essential styles. Use WordPress plugin Asset CleanUp to remove unused CSS from specific pages. Combine multiple CSS files into fewer requests through your caching plugin.

AI Performance Analysis
This WordPress site has poor performance with a score of 60/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 49 seconds, primarily caused by inefficient image delivery that could save 541 KB and improve loading by 750ms. The site also suffers from render-blocking CSS files that delay initial page rendering by over 3 seconds, and has no caching configured for large image assets totaling 7 MB. Optimizing image sizes, implementing proper caching headers, and deferring non-critical CSS could dramatically improve the site's performance and user experience.
Other Optimization Recommendations

How to Fix:
Resize the banner image from 1920x1080 to 721x406 to match display dimensions. Convert the 379 KiB GIF to MP4 video format for 80% size reduction. Use WordPress plugins like ShortPixel or Smush to automatically compress and serve WebP formats.
Remove Unused JavaScript Code
Medium Impact+12 points estimatedWhy It Matters:
80 KiB of unused JavaScript is delaying LCP by 350ms and wasting user bandwidth.
How to Fix:
Disable unused WordPress plugins and remove Google Analytics if not needed. Use Asset CleanUp Pro to selectively load scripts only on pages that need them. Defer non-critical JavaScript using your LiteSpeed Cache plugin's optimization features.
