Reduce JavaScript Execution Time
High Impact+15 points estimated
Why It Matters
JavaScript execution takes 2.5 seconds and blocks the main thread for 600ms, severely impacting interactivity with a 20-second TTI.
How to Fix
Remove or defer the heavy ContentSquare tracking script (737ms execution time) until after page load. Audit WordPress plugins for unused JavaScript and remove unnecessary ones. Use code splitting to load only essential JavaScript initially, deferring analytics and tracking scripts.

AI Performance Analysis
This WordPress site has poor performance issues with a score of 59/100. The biggest problem is extremely slow JavaScript execution taking 2.5 seconds, which causes an alarming 20-second delay before the page becomes fully interactive. The site is also suffering from render-blocking resources that delay initial page display by 650ms and oversized images that waste 637KB of bandwidth. Reducing JavaScript execution time, deferring non-critical scripts, and optimizing image sizes could improve your score by 30+ points and dramatically reduce the painfully long wait time users currently experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+25 points estimatedWhy It Matters:
CSS and JavaScript files are blocking initial page render, delaying FCP by 650ms and contributing to the poor 2.7s FCP score.
How to Fix:
Use a WordPress optimization plugin like WP Rocket or LiteSpeed Cache to automatically inline critical CSS. Defer non-critical JavaScript files including ua-parser.js and move them to load after page content. Minify and combine CSS files to reduce the number of blocking requests.
Optimize Images for Performance
High Impact+20 points estimatedWhy It Matters:
Oversized images waste 637KB of bandwidth and the hero banner alone is 4600x2251 pixels when only 668x327 is displayed.
How to Fix:
Install ShortPixel or Smush to automatically compress and resize images. Create responsive image sets using WordPress's built-in srcset functionality. Convert PNG badge images to WebP format for 60-80% size reduction. Set proper dimensions in your theme's image elements.
