Reduce Main Thread Blocking Time
High Impact+20 points estimated
Why It Matters
JavaScript execution blocks the main thread for 2.3 seconds, preventing user interactions and delaying TTI to 15.6 seconds.
How to Fix
Audit WordPress plugins and remove unused ones contributing to Script Evaluation time. Use WP Rocket or Autoptimize to defer non-critical JavaScript. Move Google Tag Manager and Facebook Pixel scripts to load after page interactive using async or defer attributes.

AI Performance Analysis
This WordPress site has poor performance with a score of 60/100. The biggest problem is excessive JavaScript execution that's blocking the main thread for 2.3 seconds, causing your Time to Interactive to reach a sluggish 15.6 seconds and your Largest Contentful Paint to hit 15.4 seconds. The site is also loading oversized images (saving potential of 1,611 KB) and has significant unused JavaScript and CSS that could be reduced by 230 KB and 83 KB respectively. Optimizing your JavaScript delivery, compressing and properly sizing images, and removing unused code could dramatically improve your Core Web Vitals and cut loading times by more than half.
Other Optimization Recommendations
Optimize Large Banner Images
High Impact+25 points estimatedWhy It Matters:
Two mobile banner images (1.2MB) delay LCP by 15+ seconds and consume excessive bandwidth.
How to Fix:
Compress banner-spirulina-mobile.png and banner-ovaz-mobile.png using ShortPixel or TinyPNG to achieve 60-80% size reduction. Convert to WebP format and create properly sized versions (412x275) instead of serving oversized 1500x1000 images. Add fetchpriority='high' to the first visible banner image.
Eliminate Render Blocking Resources
High Impact+15 points estimatedWhy It Matters:
Critical CSS and JavaScript files delay First Contentful Paint by 1.57 seconds, blocking initial page rendering.
How to Fix:
Inline critical CSS for above-the-fold content in the HTML head. Use WordPress plugins like WP Rocket to defer jQuery and non-critical CSS files. Minify CSS files (shop.css, style.css, elements.css) to save 20KB and reduce transfer time.
