Optimize Images and Implement Caching
High Impact+15 points estimated
Why It Matters
Large unoptimized images waste 375 KiB and poor cache settings force repeated downloads, severely impacting LCP.
How to Fix
Install ShortPixel or Smush to compress images and convert to WebP format. Use WP Rocket or W3 Total Cache to set browser cache headers to 1 year for images. Resize the 600x715 product image to match its 280px display width in WordPress media settings.

AI Performance Analysis
This WordPress site has poor performance with a score of 58/100. The biggest problem is extremely slow loading times, with your Largest Contentful Paint taking 8.0 seconds and pages becoming interactive only after 15.1 seconds. The main culprits are render-blocking CSS files that delay initial page rendering by 630ms, oversized and unoptimized images wasting 375KB of bandwidth, and poor caching settings that force users to re-download the same resources repeatedly. Fixing these image optimization and caching issues alone could potentially save over 1MB of data and improve loading speeds by several seconds, dramatically enhancing user experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+12 points estimatedWhy It Matters:
Critical CSS and fonts block page rendering for 650ms, directly delaying your LCP of 8.0 seconds.
How to Fix:
Install WP Rocket or Autoptimize to inline critical CSS. Move non-critical stylesheets below the fold using media='print' then swap to 'all' via JavaScript. Preload key fonts using <link rel='preload'> in your theme's header.php.
Reduce JavaScript Execution Time
Medium Impact+8 points estimatedWhy It Matters:
Heavy JavaScript processing blocks the main thread for 2.4 seconds, preventing user interactions and delaying page readiness.
How to Fix:
Use Asset CleanUp plugin to remove unused Google Ads and Analytics code from non-conversion pages. Defer non-critical scripts using WP Rocket's JavaScript optimization. Consider switching from Google Tag Manager to lighter alternatives like Plausible for basic tracking.
