Remove Unused JavaScript Code
High Impact+12 points estimated
Why It Matters
347 KiB of unused JavaScript from Google Tag Manager and Facebook SDK increases load time by 1.95 seconds.
How to Fix
Audit Google Tag Manager configurations to remove unused tags and triggers. Use Google Tag Manager's built-in tag loading optimization. Consider replacing Facebook SDK with lighter pixel implementation or loading it conditionally only when needed.

What This Score Means
A score of 59 falls in the "Needs Improvement" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This WordPress site has poor performance with a score of 59/100. The biggest problem is extremely slow page loading, with the Largest Contentful Paint taking 19.7 seconds - far beyond acceptable limits. The site is loading way too much JavaScript (347KB of unused code) and has massive images that aren't optimized, including a 1.6MB PNG file that should be converted to WebP format and properly resized. Fixing these image issues alone could save nearly 2MB of data transfer and dramatically improve loading times, while removing unused JavaScript could save an additional 1.9 seconds of load time.
Other Optimization Recommendations
Eliminate Render Blocking JavaScript
High Impact+18 points estimatedWhy It Matters:
Critical JavaScript files are blocking initial render, delaying LCP by 800ms and preventing content from displaying.
How to Fix:
Use a WordPress optimization plugin like WP Rocket to defer jQuery and other non-critical scripts. Move jQuery to load asynchronously or use defer attribute. Consider inlining critical JavaScript or loading it after the initial render.
Optimize Image Delivery Performance
High Impact+15 points estimatedWhy It Matters:
Large unoptimized images waste 1,952 KiB of bandwidth and significantly delay LCP, especially the main content image.
How to Fix:
Install ShortPixel or Imagify to automatically convert PNG images to WebP format for 70% size reduction. Resize the main hero image to match display dimensions (581x656 instead of 768x1152). Enable responsive images with proper srcset attributes in your WordPress theme.
