AI Performance Analysis

This WordPress website has severe performance issues with a critically low score of 25/100. The biggest problem is excessive JavaScript execution taking over 19 seconds, primarily from third-party widgets like reviews and YouTube embeds, which is causing a devastating 16.8-second Largest Contentful Paint and nearly 4-second Total Blocking Time. The site is also suffering from a lazy-loaded hero image that should load immediately, over 1MB of unused JavaScript and CSS (especially from YouTube and review widgets), and forced layout reflows that further slow down rendering. Removing or optimizing these heavy third-party scripts, fixing the lazy-loading on critical images, and cleaning up unused code could potentially improve the performance score by 50+ points and dramatically enhance user experience.

Other Optimization Recommendations

Fix LCP Image Loading Issues

High Impact+25 points estimated

Why It Matters:

Your LCP image uses lazy loading and lacks priority hints, delaying it by 1.45 seconds and creating a 16.8s LCP.

How to Fix:

Remove loading='lazy' from the hero car image and add fetchpriority='high'. Use a WordPress plugin like WP Rocket to automatically optimize LCP images. Consider using a smaller, optimized image specifically for mobile viewport.

Optimize Image Delivery and Format

High Impact+15 points estimated

Why It Matters:

Images are oversized and uncompressed, wasting 1MB of bandwidth and slowing LCP by 1.8 seconds.

How to Fix:

Install ShortPixel or Imagify to convert PNG images to WebP format for 50-70% size reduction. Use WordPress responsive images with proper srcset attributes. Resize the Subject image from 768x991px to match its 172x222px display size.
