AI Performance Analysis
This WordPress site has poor performance with a score of 61/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 15.3 seconds, caused primarily by oversized banner images that are loading at full resolution (1500x1000) but displaying much smaller (412x275). The site is also blocked by 229 KiB of unused JavaScript from Google Tag Manager and Facebook tracking scripts, plus 84 KiB of unused CSS that's preventing the page from rendering quickly. Converting images to modern formats like WebP, properly sizing them for mobile displays, and cleaning up the excessive JavaScript could dramatically improve load times and boost the performance score by 30+ points.
Other Optimization Recommendations
Optimize Critical Images and Formats
High Impact+25 points estimatedWhy It Matters:
Large banner images delay LCP by 15+ seconds and waste 1,611 KiB with poor compression and sizing.
How to Fix:
Convert banner images to WebP/AVIF format using ShortPixel plugin. Create responsive image sizes matching display dimensions (412x275 for mobile banners vs current 1500x1000). Add fetchpriority='high' to LCP banner image and remove lazy loading from above-the-fold content.
Reduce Main Thread Blocking Time
Medium Impact+12 points estimatedWhy It Matters:
2.1 seconds of main thread work creates 220ms blocking time, preventing user interactions and degrading INP.
How to Fix:
Defer Google Analytics and Facebook Pixel loading until after page interactive using GTM's built-in triggers. Split large JavaScript bundles using code splitting in your theme's build process. Move theme initialization scripts to load after critical content renders.
