Eliminate Render Blocking CSS
High Impact+15 points estimated
Why It Matters
The main CSS file is blocking initial render for 950ms, significantly delaying both LCP and FCP.
How to Fix
Inline critical CSS directly in the HTML head for above-the-fold content. Load the remaining CSS asynchronously using media='print' onload technique or rel='preload'. Split CSS into critical and non-critical parts to reduce blocking time.

What This Score Means
A score of 100 falls in the "Good" 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 achieves a perfect performance score of 100/100, indicating excellent loading speeds and user experience. However, there are still optimization opportunities that could make the site even faster, particularly the render-blocking CSS file (banner.B9Kfk2py.css) which is delaying initial page rendering by nearly 1 second and could be deferred or inlined. The site also has a chain of font loading dependencies where custom fonts load after the CSS, creating a 319ms loading sequence that could be optimized with font preloading. Minor improvements include setting longer cache lifetimes for the analytics script and addressing some forced reflows in JavaScript, but overall this site is already performing exceptionally well.
Other Optimization Recommendations
Optimize Font Loading Strategy
Medium Impact+8 points estimatedWhy It Matters:
Three Space Grotesk font variants are loaded sequentially, extending the critical path to 319ms.
How to Fix:
Add font-display: swap to @font-face rules to prevent invisible text during font load. Preload only the most critical font weight (400) using rel='preload'. Consider using a variable font to reduce the number of font files from three to one.
Extend Cache Lifetime for Analytics
Low Impact+2 points estimatedWhy It Matters:
Plausible analytics script has only 1-minute cache lifetime, causing unnecessary re-downloads for returning visitors.
How to Fix:
Configure your server or CDN to serve the analytics script with longer cache headers (e.g., 1 week). If using a reverse proxy, set cache-control headers to max-age=604800. Consider self-hosting the analytics script for better cache control.
