Optimize Image Delivery and Sizing
High Impact+25 points estimated
Why It Matters
Images cause 1,522 KiB waste and trigger major layout shifts (CLS: 0.397), severely impacting LCP by 8.35 seconds.
How to Fix
Install WebP Express plugin to convert images to WebP format automatically. Add explicit width/height attributes to all img tags, especially in the 3D carousel. Use responsive image srcsets with proper sizing for mobile devices. Enable lazy loading for below-the-fold images.

AI Performance Analysis
This WordPress site has serious performance problems with a very poor score of 36/100. The biggest issue is massive layout shifts (CLS of 0.397) caused by images without explicit width and height dimensions, which makes the page jump around as content loads. Additionally, the site loads an enormous 13.7 MB of data with extremely slow loading times - it takes over 59 seconds for the largest content to appear and 69 seconds to become interactive. The most impactful fixes would be adding explicit dimensions to all images, optimizing and compressing the oversized image files (some are over 1 MB each), and removing unused CSS and JavaScript that's bloating the page size.
Other Optimization Recommendations
Eliminate Render-Blocking Resources
High Impact+20 points estimatedWhy It Matters:
Render-blocking CSS and JavaScript delay First Contentful Paint by 12 seconds, blocking initial page rendering.
How to Fix:
Install Autoptimize or WP Rocket to minify and combine CSS/JS files. Defer non-critical JavaScript like RevSlider and ElementsKit widgets. Inline critical CSS for above-the-fold content. Remove unused CSS from blog layout and hover effects plugins.
Reduce JavaScript Execution Time
High Impact+15 points estimatedWhy It Matters:
Heavy JavaScript execution (1.5s) blocks the main thread and causes forced reflows, delaying interactivity.
How to Fix:
Audit WordPress plugins - consider replacing RevSlider with lighter alternatives. Remove unused JavaScript from ElementsKit and 3D carousel plugins. Implement code splitting to load scripts only when needed. Enable WordPress script concatenation and compression.
