AI Performance Analysis
This WordPress site has severe performance problems with a poor score of 43/100. The biggest issue is an extremely slow Largest Contentful Paint of 24.8 seconds, caused primarily by a massive 1.4MB background image that's poorly optimized and blocks page rendering. The site also suffers from 871 KiB of unused JavaScript from third-party widgets and reCAPTCHA, plus render-blocking scripts that delay initial page display by 4.5 seconds. Compressing and modernizing that large background image, removing unnecessary JavaScript, and deferring non-critical scripts could potentially improve the performance score by 30+ points and dramatically reduce load times from nearly 25 seconds to under 5 seconds.
Other Optimization Recommendations
Optimize Image Delivery and Caching
High Impact+20 points estimatedWhy It Matters:
Images consume 1.4 MB without proper compression and caching, causing 5.7 second LCP delay.
How to Fix:
Install WP Rocket or W3 Total Cache to set proper cache headers (min 1 year for images). Use ShortPixel to compress the 1.4MB bg_block.png.webp by 80%. Implement responsive images with srcset for carousel images to serve appropriate sizes for mobile devices.
Fix Image Dimensions for CLS
Medium Impact+8 points estimatedWhy It Matters:
Missing width/height attributes on carousel images cause layout shifts as content loads and repositions.
How to Fix:
Add explicit width and height attributes to all carousel images in your WordPress theme templates. Set aspect-ratio CSS property as fallback for better browser support. Use WordPress's built-in responsive image features to maintain proper dimensions across devices.
