High Impact+15 points estimated
Why It Matters
Oversized images waste 378 KiB and delay LCP by 300ms as 2500x1000 images are displayed at only 412x165 pixels.
How to Fix
Configure WordPress to generate proper responsive image sizes in your theme's functions.php with add_image_size(). Install ShortPixel or Imagify to automatically serve correctly sized images. Ensure your srcset attributes include dimensions matching actual display sizes (412px, 768px, 1200px).

AI Performance Analysis
This WordPress site has poor performance with a score of 52/100, indicating significant user experience issues. The biggest problem is extremely slow JavaScript execution taking 2.3 seconds, primarily from ReCaptcha and the site's main app.js file, which is severely delaying page interactivity and causing a terrible Largest Contentful Paint of 17.7 seconds. Additionally, images are oversized for their display dimensions, wasting 378 KiB of bandwidth, and there's 630 KiB of unused JavaScript being loaded unnecessarily. Optimizing or deferring JavaScript execution, properly sizing images, and removing unused code could dramatically improve this site's performance by 15-20 points and provide a much better user experience.
Other Optimization Recommendations
Reduce JavaScript Execution Time
High Impact+18 points estimatedWhy It Matters:
JavaScript execution takes 2.3 seconds and blocks the main thread, causing 350ms TBT impact and preventing user interactions.
How to Fix:
Remove or defer the heavy reCAPTCHA script (730ms execution time) by loading it only when contact forms are accessed. Optimize your theme's app.js file which takes 242ms to execute. Use WP Rocket's JavaScript optimization features to defer non-critical scripts until after page load.
Implement Efficient Cache Headers
Medium Impact+8 points estimatedWhy It Matters:
Poor caching wastes 209 KiB on repeat visits and delays LCP by 1.65 seconds for returning users.
How to Fix:
Configure your WordPress caching plugin (W3 Total Cache or WP Super Cache) to set longer cache lifetimes for static assets. Set browser cache headers for JavaScript files to at least 1 year. Contact your CloudFront CDN provider to fix the zero-cache-lifetime on leadbot.min.js.
