Fix LCP Image Discovery
High Impact+20 points estimated
Why It Matters
LCP image has 5.8 second resource load delay because it's not discoverable in initial HTML.
How to Fix
Move the hero image (img.uticket.com.br/event/01LSQUKU4KINFH/l) from JavaScript-rendered content to static HTML. Add fetchpriority='high' attribute to the LCP image element. Preload the image using <link rel='preload' as='image'> in the document head.

What This Score Means
A score of 27 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.

AI Performance Analysis
This event ticketing website has severe performance issues with a critically low score of 27/100. The biggest problem is an enormous amount of unused JavaScript (1,285 KiB) that's blocking the page from loading quickly, causing the Largest Contentful Paint to take a devastating 21.7 seconds and First Contentful Paint to reach 7.4 seconds. The site is also suffering from poor caching strategies and inefficient network requests that create long dependency chains, with Google Fonts taking nearly 6 seconds to load. Removing unused JavaScript code, implementing better caching policies, and optimizing the main JavaScript bundle could potentially improve the score by 40+ points and dramatically reduce load times from over 20 seconds to under 5 seconds.
Other Optimization Recommendations
Optimize JavaScript Bundle Size
High Impact+25 points estimatedWhy It Matters:
Unused JavaScript (1,285 KiB) is blocking main thread for 4.3 seconds and delaying LCP by 6.75 seconds.
How to Fix:
Use webpack-bundle-analyzer to identify unused code in main.60c52c31.js. Implement code splitting to load only critical JavaScript initially. Remove unused polyfills and use modern ES6+ features for supported browsers. Consider lazy loading non-critical components.
Implement Efficient Caching Strategy
Medium Impact+8 points estimatedWhy It Matters:
Short cache lifetimes (4 hours for main JS) force unnecessary re-downloads and slow repeat visits.
How to Fix:
Configure your web server to cache static assets (JS, CSS, images) for at least 1 year with cache-control headers. Use content hashing in filenames to enable safe long-term caching. Set up CDN caching for third-party resources like Google Fonts and Facebook scripts.
