Implement Proper Browser Caching
High Impact+20 points estimated
Why It Matters
Zero cache lifetime on critical assets forces 3.5MB of unnecessary downloads on every visit, adding 15.7 seconds to LCP.
How to Fix
Configure your CDN to serve static assets with Cache-Control headers of at least 1 year (31536000 seconds). Implement filename versioning for cache busting during updates. Set appropriate cache headers for CSS, JS, and font files.

What This Score Means
A score of 30 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 website has severe performance issues with a score of only 30/100, indicating extremely poor user experience. The biggest problem is an excessive 33.4-second Largest Contentful Paint, primarily caused by a massive 2.8MB JavaScript file that has no caching and blocks the page from rendering. The site also suffers from multiple redirects adding nearly a second of delay, and over 2.5MB of unused JavaScript that could be eliminated. Implementing proper caching, removing unused code, and fixing the redirect chain could dramatically improve load times and boost the performance score by 40+ points.
Other Optimization Recommendations
Eliminate Massive JavaScript Bundle
High Impact+25 points estimatedWhy It Matters:
The 2.8MB JavaScript file blocks rendering for 13.7 seconds and wastes 70% unused code, severely delaying all Core Web Vitals.
How to Fix:
Split the monolithic embed_assets bundle using dynamic imports and code splitting. Remove unused libraries and implement tree-shaking to eliminate dead code. Defer non-critical JavaScript modules until after initial page load.
Remove Trailing Slash Redirect
Medium Impact+8 points estimatedWhy It Matters:
The unnecessary redirect from /location to /location/ adds 850ms delay before any content can begin loading.
How to Fix:
Update internal links to use the canonical URL with trailing slash. Configure your web server to serve the correct URL directly without redirects. Update any marketing campaigns or bookmarks pointing to the non-trailing slash version.
