Eliminate Unused JavaScript Bundles
High Impact+15 points estimated
Why It Matters
196KB of unused JavaScript creates 920ms delay and blocks the main thread, preventing user interactions.
How to Fix
Configure Next.js bundle analyzer to identify unused code in chunks. Remove or lazy-load the 95% unused code in 2655324f1ab61a54.js and b772289a746aa74b.js chunks. Defer Google Analytics loading using next/script with strategy='afterInteractive' instead of direct gtag implementation.

What This Score Means
A score of 49 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 Next.js site has serious performance issues with a poor score of 49/100. The biggest problem is an extremely slow Largest Contentful Paint of 15.2 seconds, caused primarily by a massive 275KB logo image that's displayed at only 109x105 pixels and suffers from a 4.7-second resource load delay. The site is also bloated with 196KB of unused JavaScript from Google Analytics and other scripts that aren't needed immediately. Resizing and properly optimizing images, removing unused JavaScript, and implementing better caching strategies could dramatically improve the score by 30+ points and make the site usable for visitors.
Other Optimization Recommendations
Optimize Critical Image Delivery
High Impact+18 points estimatedWhy It Matters:
The main logo (275KB) and LCP image cause a 950ms delay to Largest Contentful Paint, severely impacting user experience.
How to Fix:
Resize the logo from 2852x2696 to actual display size (109x105) using Next.js Image component with proper width/height props. Implement responsive images for the event card image using Next.js Image with optimized srcSet. Enable WebP format in next.config.js with formats: ['image/webp', 'image/avif'].
Fix Resource Load Delays
Medium Impact+12 points estimatedWhy It Matters:
4.67 second resource load delay dominates the LCP breakdown, indicating inefficient resource prioritization.
How to Fix:
Add resource hints in next/head for critical assets using <link rel='preload'>. Configure proper cache headers for static assets - set logo.png to 1 year instead of 4 hours. Implement Next.js priority prop on the LCP image element to prioritize its loading over other resources.
