Eliminate Render-Blocking Resources
High Impact+12 points estimated
Why It Matters
Render-blocking CSS and JavaScript delay First Contentful Paint by 1.92 seconds and prevent users from seeing content immediately.
How to Fix
Defer bootstrap.min.js by adding 'defer' attribute to the script tag. Inline critical CSS for above-the-fold content directly in the HTML head. Load font-awesome.min.css asynchronously using media='print' onload="this.media='all'" technique.

What This Score Means
A score of 82 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 a decent performance score of 82/100, but has significant room for improvement in loading speed. The biggest issue is render-blocking resources (CSS and JavaScript files) that are delaying the page from displaying content, wasting nearly 2 seconds and causing a slow First Contentful Paint of 3.3 seconds. The site is also suffering from an unnecessary redirect and oversized images that could be optimized with modern formats like WebP. Fixing the render-blocking resources by deferring non-critical CSS/JavaScript and optimizing the large blog images could easily push this site into the 90+ performance range and dramatically improve the user experience.
Other Optimization Recommendations
Fix Redirect Chain
High Impact+8 points estimatedWhy It Matters:
The redirect from koku-scripts.com to www.koku-scripts.com adds 780ms delay to every Core Web Vital metric.
How to Fix:
Update your domain configuration to serve content directly from www.koku-scripts.com without redirecting. Configure your web server (Apache/Nginx) to handle the canonical domain properly. Update all internal links to use the www version consistently.
Optimize Image Delivery Format
High Impact+6 points estimatedWhy It Matters:
Blog images are oversized PNGs that could be 583KB smaller using modern formats, directly impacting LCP performance.
How to Fix:
Convert PNG blog images to WebP format for 60-80% size reduction. Implement responsive images with srcset to serve appropriate dimensions (668x382 instead of 700x400). Add explicit width and height attributes to prevent layout shifts during loading.
