Implement Modern Image Optimization
High Impact+18 points estimated
Why It Matters
Images waste 9.5 MB in unnecessary data transfer and cause poor LCP performance with 2+ second resource load delays.
How to Fix
Install ShortPixel or Imagify to convert images to WebP/AVIF format for 30% size reduction. Generate responsive image sizes to serve 616x462 instead of 1440x1080 originals. Add fetchpriority='high' to the mobile logo LCP element and ensure it's discoverable in initial HTML.

AI Performance Analysis
This WordPress site has severe performance issues with a score of only 44/100. The biggest problem is excessive JavaScript execution taking over 6 seconds of main-thread work, particularly from Revolution Slider plugins that are causing 730ms of blocking time and delaying user interactions until 43.6 seconds. The site is also loading nearly 14MB of unoptimized images and has 106KB of unused CSS that could be removed. Removing or optimizing the heavy JavaScript plugins, compressing images to modern formats like WebP, and cleaning up unused code could easily improve the score by 30+ points and make the site usable for visitors.
