Why It Matters
JavaScript is causing 92ms of forced reflows, blocking the main thread and delaying user interactions.
How to Fix
Optimize the Kadence accordion JavaScript by batching DOM reads and writes. Update to the latest Kadence Blocks version which may have performance fixes. Consider replacing heavy accordion functionality with CSS-only solutions where possible.

AI Performance Analysis
This WordPress site has good performance with a score of 93/100, but there are still some optimization opportunities. The biggest issue is render-blocking CSS files from the Kadence Blocks plugin that are delaying page rendering by 530ms and affecting the First Contentful Paint. Additionally, JavaScript code is causing forced reflows (layout recalculations) that waste about 93ms of processing time, mainly from the accordion functionality. Quick wins include deferring or inlining the blocking CSS files, implementing better caching (currently missing for some resources), and optimizing the accordion JavaScript to reduce layout thrashing.
Other Optimization Recommendations
Eliminate Render-Blocking CSS
High Impact+12 points estimatedWhy It Matters:
Kadence Blocks CSS files are blocking initial render and delaying First Contentful Paint by 550ms.
How to Fix:
Install a WordPress optimization plugin like WP Rocket or Autoptimize to inline critical CSS. Defer non-critical Kadence Blocks stylesheets using loadCSS or similar techniques. Combine multiple small CSS files to reduce HTTP requests.
Implement Proper Browser Caching
Medium Impact+5 points estimatedWhy It Matters:
The TrustIndex script has no cache headers, forcing unnecessary downloads on repeat visits and adding 200ms to LCP.
How to Fix:
Add cache headers via your WordPress caching plugin or .htaccess file for all static assets. Set cache lifetime to 1 year for versioned resources. Configure your CDN or hosting provider to serve assets with proper Cache-Control headers.
