Optimize CSS Delivery Strategy
Medium Impact+6 points estimated
Why It Matters
Render-blocking CSS and 33KB of unused styles are delaying first paint by 350ms.
How to Fix
Inline critical CSS directly in the HTML head for above-the-fold content. Load the remaining CSS asynchronously using media='print' onload technique. Remove unused CSS rules from index-BjYuMvG_.css (91% unused). Use PurgeCSS or similar tools during build to eliminate dead CSS.

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 moderate performance issues with a score of 72/100, indicating room for significant improvement. The biggest problem is multiple page redirects that are adding 780ms of unnecessary delay before the page even starts loading, which directly impacts user experience. The site is also suffering from bloated code, with 84KB of unused JavaScript and 33KB of unused CSS that could be removed to speed up loading times. Most critically, the Largest Contentful Paint takes 6.4 seconds, which is far too slow and will frustrate visitors - fixing the redirects and cleaning up the unused code could easily improve the performance score by 15-20 points and provide a much faster, smoother user experience.
Other Optimization Recommendations
Eliminate Multiple Page Redirects
High Impact+12 points estimatedWhy It Matters:
Redirects are adding 780ms delay and directly impacting LCP by 800ms, creating the biggest performance bottleneck.
How to Fix:
Update all internal links and canonical URLs to point directly to https://www.prenotaofficina.it/ instead of the non-www version. Configure server to serve the www version directly without redirecting from prenotaofficina.it. Update any external references and social media links to use the final URL.
Remove Unused JavaScript Code
High Impact+8 points estimatedWhy It Matters:
84KB of unused JavaScript is delaying LCP by 450ms and preventing page interactivity.
How to Fix:
Analyze index-DH6OJpmO.js (57KB wasted, 43% unused) and InfoHome-MVBnKouZ.js (29KB wasted, 71% unused) using webpack-bundle-analyzer. Split large bundles using dynamic imports for route-specific code. Implement tree-shaking to eliminate dead code during build process.
