AI Performance Analysis

This WordPress site has poor performance with a score of 51/100, indicating significant issues that need attention. The biggest problem is an extremely slow Largest Contentful Paint of 7.4 seconds, which is well above the recommended 2.5 seconds and creates a frustrating user experience. The site is loading 235 KiB of unused CSS and 272 KiB of unused JavaScript (primarily from Google Analytics and tracking scripts), while also suffering from major layout shifts caused by improperly sized images and web font loading. The most impactful fixes would be removing or deferring unused code, properly sizing images (which could save 97 KiB), and adding explicit dimensions to prevent layout shifts - these improvements could easily boost the performance score by 30+ points.

Other Optimization Recommendations

Fix Layout Shift Issues

High Impact+25 points estimated

Why It Matters:

Layout shifts (CLS: 0.309) cause poor user experience and significantly hurt search rankings.

How to Fix:

Add explicit width and height attributes to all images, especially the carousel images causing shifts. Set font-display: swap for custom fonts and use font fallbacks with similar metrics. Reserve space for dynamic content with CSS min-height properties.

Implement Responsive Image Sizing

Medium Impact+8 points estimated

Why It Matters:

Images are 97KB larger than needed, wasting bandwidth and slowing LCP.

How to Fix:

Configure WordPress responsive images with proper srcset attributes. Use ShortPixel to generate multiple image sizes automatically. Set max display dimensions in your Divi theme to match actual usage (577px vs 980px currently served).
