How to Fix
Remove or defer Google Tag Manager (107 KiB unused). Audit support.ona.co.il and www.ona.co.il/mzyy/ scripts for actual usage. Use code splitting to load JavaScript only when needed. Implement dynamic imports for non-critical features.

AI Performance Analysis
This website has severely poor performance with a score of just 41/100. The biggest problem is an extremely slow Largest Contentful Paint of 11.7 seconds, primarily caused by excessive unused JavaScript (544 KiB that could be eliminated) and render-blocking resources that delay page loading by nearly 2 seconds. The site is loading far too much unnecessary code from tracking scripts, third-party widgets, and unused CSS/JavaScript files, which is creating a 19.6-second delay before the page becomes fully interactive. Removing unused JavaScript, optimizing CSS delivery, and addressing the massive 3.2 MB network payload could dramatically improve performance and user experience.
Other Optimization Recommendations
Remove Unused CSS Stylesheets
High Impact+20 points estimatedWhy It Matters:
208 KiB of unused CSS delays rendering and LCP by 1.2 seconds.
How to Fix:
Remove completely unused dashicons.min.css (35 KiB). Optimize support.ona.co.il widget CSS to remove 98% unused rules. Use PurgeCSS or similar tools to eliminate dead CSS from Flatsome theme. Inline critical CSS for above-the-fold content.
Optimize LCP Image Discovery
High Impact+18 points estimatedWhy It Matters:
LCP image takes 11.7 seconds to load due to poor resource discovery and lacks priority hints.
How to Fix:
Add fetchpriority='high' to the hero image (mansittingpetrol-copy.jpg). Preload the LCP image in the HTML head section. Remove lazy loading from above-the-fold images. Optimize image size from 567x676 to actual display dimensions.
