Reduce Main Thread Blocking
High Impact+15 points estimated
Why It Matters
JavaScript execution blocks the main thread for 3.8 seconds, preventing user interactions and delaying page rendering.
How to Fix
Use Asset CleanUp or WP Rocket to defer jQuery and non-critical scripts. Remove or replace heavy plugins causing 'Style & Layout' work. Consider lazy-loading WooCommerce scripts only on product pages.

AI Performance Analysis
This WordPress site has poor performance with a score of 74/100, primarily due to excessive main-thread blocking that takes 3.8 seconds to complete. The biggest issue is your Largest Contentful Paint (LCP) at 5.4 seconds, which is caused by a lazily-loaded hero image that should be prioritized for immediate loading. The site is also weighed down by 28 KiB of unused CSS (particularly from the Shoptimizer theme), 65 KiB of unused JavaScript from Google Analytics, and inefficient image delivery that could save 178 KiB through better compression and modern formats. Removing lazy loading from your main hero image, cleaning up unused code, and optimizing your images could improve your performance score by 15-20 points and significantly enhance user experience.
Other Optimization Recommendations
Remove LCP Lazy Loading
High Impact+18 points estimatedWhy It Matters:
Your LCP image uses loading='lazy' which delays the most important content by 2.1 seconds.
How to Fix:
Locate the hero image in your WordPress theme (car-seat-for-dogs image). Remove the loading='lazy' attribute and add fetchpriority='high' instead. Consider using a plugin like WP Rocket to automatically prioritize above-the-fold images.
Optimize Image Compression
Medium Impact+12 points estimatedWhy It Matters:
Poor image compression wastes 178 KiB and delays LCP by 450ms, especially affecting your hero images.
How to Fix:
Install ShortPixel or Imagify plugin to compress existing images. Configure to serve WebP format for modern browsers. Set compression quality to 85% for JPGs. Use WordPress responsive images properly with correct srcset attributes.
