Optimize Large Video File Caching
High Impact+10 points estimated
Why It Matters
18MB of video content lacks proper caching headers, forcing re-downloads on repeat visits and contributing to the 5-second LCP.
How to Fix
Configure your CDN (NitroCDN) to set cache-control headers for .webm files with max-age=31536000 (1 year). Add expires headers in your .htaccess file for video content. Consider using adaptive streaming or poster images with click-to-play for above-the-fold videos to reduce initial payload.

What This Score Means
A score of 78 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 website has below-average performance with a score of 78/100, but faces significant Core Web Vitals issues that hurt user experience. The biggest problem is an extremely slow Largest Contentful Paint of 5.0 seconds, caused primarily by render-blocking JavaScript files from Elementor plugins that delay initial page rendering by 900ms. The site is also bloated with a massive 70MB payload, mostly from large video files that aren't properly cached, and contains 136KB of unused JavaScript from Google Tag Manager scripts. Addressing the render-blocking resources and implementing proper caching for the video content could dramatically improve load times and user experience.
Other Optimization Recommendations
Defer Render-Blocking JavaScript Resources
High Impact+12 points estimatedWhy It Matters:
Elementor JavaScript files block page rendering for 900ms, significantly delaying First Contentful Paint.
How to Fix:
Add defer or async attributes to Elementor frontend scripts. Use WordPress hooks to modify script loading: add_filter('script_loader_tag', 'defer_scripts', 10, 3). Move non-critical Elementor handlers to load after page interactive. Consider using a performance plugin like WP Rocket to automatically defer JavaScript.
Remove Unused CSS and JavaScript
Medium Impact+8 points estimatedWhy It Matters:
136KB of unused JavaScript and 63KB of unused CSS waste bandwidth and slow down page parsing.
How to Fix:
Use Asset CleanUp Pro or Perfmatters to disable unused plugins on specific pages. Remove unused Google Tag Manager containers (you have two GTM instances loading). Purge unused CSS from Elementor by enabling 'Optimized CSS Loading' in Elementor > Settings > Features. Audit and remove redundant tracking scripts.
