Fix Image Dimensions for CLS
Medium Impact+8 points estimated
Why 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.

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
Remove Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
Unused JavaScript wastes 892 KiB and delays LCP by 5.1 seconds, severely impacting page load performance.
How to Fix:
Use WP Asset CleanUp to disable unnecessary plugins on specific pages. Remove duplicate reCAPTCHA scripts and unused Sleak chat widget code. Implement code splitting for WordPress themes to load only required JavaScript modules per page.
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.
