Why It Matters

Images lack proper sizing causing layout shifts and use outdated formats, wasting 161 KiB and hurting user experience.

How to Fix

Install ShortPixel to automatically convert PNG/JPEG to WebP format for 20-30% size reduction. Add explicit width and height attributes to all img tags including your VisualFizz logo SVGs. Enable responsive images in WordPress to serve appropriately sized images based on device viewport.

AI Performance Analysis

This WordPress site has good performance with a score of 80/100, but there's significant room for improvement. The biggest issue is render-blocking resources that are delaying your page's initial display, causing slow First Contentful Paint (3.2s) and Largest Contentful Paint (3.8s) times. Your main stylesheet and JavaScript files are preventing the page from rendering quickly, with an estimated 2.3 seconds that could be saved by deferring or optimizing these resources. Additionally, you're serving 251KB of unused JavaScript and 64KB of unused CSS, plus your images could be optimized with modern formats like WebP to save another 161KB. Addressing the render-blocking resources first would have the biggest impact on user experience.

Other Optimization Recommendations

Eliminate Render Blocking Resources

High Impact+12 points estimated

Why It Matters:

Render blocking CSS and JavaScript delay LCP and FCP by 2.35 seconds, significantly impacting page load performance.

How to Fix:

Defer non-critical CSS using WP Rocket's CSS optimization feature or manually add media='print' then switch to 'all' via JavaScript. Move the WordPress Popular Posts JS to footer using wp_enqueue_script with 'in_footer' parameter set to true. Consider inlining critical above-the-fold CSS directly in the HTML head.

Remove Unused CSS and JavaScript

High Impact+10 points estimated

Why It Matters:

251 KiB of unused JavaScript and 64 KiB of unused CSS waste bandwidth and slow parsing, directly impacting load times.

How to Fix:

Use Asset CleanUp Pro to disable unused scripts per page. Remove 70% unused code from your main theme JavaScript bundle by code splitting or tree shaking. Purge unused Bootstrap Icons CSS classes using PurgeCSS or similar tools in your build process.
