Implement Long-Term Browser Caching
High Impact+10 points estimated
Why It Matters
Zero cache lifetime on static assets forces 312 KiB re-downloads on every visit, slowing repeat visits significantly.
How to Fix
Configure WordPress caching plugin (WP Rocket or W3 Total Cache) to set 1-year expiration headers for CSS/JS files. Add cache-busting version parameters to prevent stale content. Set shorter cache (1 week) for frequently updated assets like product images.

AI Performance Analysis
This website has poor performance with a score of 66/100, primarily due to an extremely slow Largest Contentful Paint of 8.9 seconds. The biggest issue is oversized product images that are being loaded at 2267x2152 pixels but displayed at only 186x177 pixels, wasting 682 KiB of bandwidth and significantly delaying page rendering. Additionally, the site has no caching configured for JavaScript files and loads 126 KiB of unused CSS, creating unnecessary render-blocking delays. Implementing responsive images, enabling proper browser caching, and removing unused code could improve the performance score by 25+ points and dramatically speed up the user experience.
Other Optimization Recommendations
Optimize Product Image Delivery
High Impact+12 points estimatedWhy It Matters:
Oversized product images waste 682 KiB and delay LCP by 600ms with images 10x larger than needed.
How to Fix:
Implement responsive image srcset attributes for product thumbnails. Configure WooCommerce to generate properly sized thumbnails (186x177px for grid display). Use WordPress plugins like ShortPixel to automatically serve optimized WebP images at correct dimensions.
Remove Unused CSS and JavaScript
High Impact+15 points estimatedWhy It Matters:
Unused code blocks rendering for 1,050ms and wastes 192 KiB of bandwidth on every page load.
How to Fix:
Remove completely unused Dashicons CSS (100% unused, 35KB). Use Asset CleanUp Pro to disable FontAwesome icons on pages that don't need them. Audit and remove unused WooCommerce and plugin CSS. Consider critical CSS inlining for above-the-fold content.
