How to optimize ona.co.il
The LCP image has a 2.4 second resource load delay because it's not discoverable in the initial HTML and lacks priority hints.
Remove lazy loading from the hero image by removing data-lazy-src attribute and ensuring it loads immediately. Add fetchpriority='high' attribute to the LCP image. Ensure the image src is directly in HTML rather than loaded via JavaScript to make it discoverable.
A score of 47 falls in the "Poor" 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.

This website has serious performance issues with a poor score of 47/100. The biggest problem is an extremely slow Largest Contentful Paint of 12.5 seconds, primarily caused by a 2.4-second delay in loading the main hero image due to poor resource discovery and lack of proper prioritization hints. The site is also bloated with 545 KB of unused JavaScript and 208 KB of unused CSS, which blocks rendering and slows down the initial page load. Fixing the image loading by adding fetchpriority="high" to the hero image, removing unused code, and implementing better caching could improve the score by 30+ points and dramatically reduce load times for users.
Why It Matters:
CSS files are blocking first paint by 2.05 seconds, significantly delaying when users see content.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Defer non-critical CSS like cart styles and payment gateway CSS using media='print' onload technique. Use WordPress plugins like Autoptimize to automatically handle CSS optimization and critical path extraction.
Why It Matters:
545 KiB of unused JavaScript and 208 KiB of unused CSS are unnecessarily slowing down your site by 1.5 seconds.
How to Fix:
Remove or conditionally load unused WordPress plugins like dashicons.min.css (35KB) that aren't needed on frontend. Use Asset CleanUp plugin to disable scripts/styles on pages where they're not needed. Split large JavaScript bundles and only load required functionality per page.
