Optimize LCP Image Discovery
High Impact+20 points estimated
Why It Matters
The LCP image has a 4.5 second resource load delay because it's not discoverable in the initial HTML.
How to Fix
Move the banner image from JavaScript-rendered content to static HTML. Add fetchpriority='high' attribute to the LCP image element. Use a <link rel='preload'> for the banner.webp image in the document head.

AI Performance Analysis
This website has severe performance issues with a critically low score of 28/100. The biggest problem is excessive JavaScript that takes 3.8 seconds to execute, with the main JavaScript file being 873KB and containing 57% unused code that's blocking the page from becoming interactive for over 20 seconds. The site's images load extremely slowly (18.6 seconds for the largest image) because they're not discoverable in the initial HTML and lack proper optimization. Reducing the JavaScript bundle size, removing unused code, and optimizing image delivery could dramatically improve the score by 40+ points and transform the user experience from frustratingly slow to acceptable.
Other Optimization Recommendations
Reduce JavaScript Execution Time
High Impact+25 points estimatedWhy It Matters:
JavaScript execution takes 3.8 seconds, blocking user interactions and contributing 1,550ms to Total Blocking Time.
How to Fix:
Split the 873KB main bundle using React.lazy() for route-based code splitting. Remove unused code from main.js (56% is unused). Defer Google Tag Manager scripts using async/defer attributes or load them after page interactive event.
Add Image Dimensions and Preconnects
Medium Impact+8 points estimatedWhy It Matters:
Missing image dimensions can cause layout shifts, and missing preconnects delay third-party resource loading.
How to Fix:
Add explicit width and height attributes to all img elements, especially mobile-admin-event.webp and desktop-admin-event.webp. Add preconnect links for cdn.inspectlet.com, api.uticket.com.br, and www.google.co.uk to save 300-326ms on first requests.
