Optimize and Modernize Images
High Impact+18 points estimated
Why It Matters
Large unoptimized images waste 7,474 KiB and delay LCP by 450ms with poor user experience.
How to Fix
Convert racing-car.png and award images to WebP format for 60-80% size reduction. Implement responsive images with srcset for proper mobile sizing. Add explicit width/height attributes to prevent layout shifts.

What This Score Means
A score of 37 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 dental practice website has severe performance problems with a score of just 37/100. The biggest issue is massive unused JavaScript and CSS files that are blocking page rendering and taking nearly 21 seconds for the first content to appear - particularly problematic YouTube embed scripts that aren't even being fully utilized. The site is also suffering from unoptimized images (especially a 530KB racing car PNG) and layout shifts caused by images without proper dimensions. Removing unused code, optimizing images to modern formats like WebP, and adding explicit width/height attributes to images could easily improve the score by 30+ points and dramatically reduce the painfully slow load times that are likely driving visitors away.
Other Optimization Recommendations
Eliminate Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
2,710 KiB of unused JavaScript is blocking rendering and delaying LCP by 14 seconds.
How to Fix:
Remove or defer YouTube player JavaScript until user interaction with video elements. Implement code splitting to load only necessary scripts. Use webpack-bundle-analyzer to identify and eliminate dead code from your build process.
Remove Render-Blocking CSS Resources
High Impact+15 points estimatedWhy It Matters:
CSS files block initial page render for 900ms, significantly delaying First Contentful Paint.
How to Fix:
Inline critical CSS for above-the-fold content directly in HTML head. Defer non-critical CSS like animations.css and carousel styles using media='print' then JavaScript. Remove 116 KiB of unused CSS from Bootstrap and YouTube embeds.
