Optimize and Resize Images
High Impact+15 points estimated
Why It Matters
Oversized images are wasting 237KB of bandwidth and delaying LCP by 150ms while causing layout shifts.
How to Fix
Generate responsive image sizes for different screen widths using srcset attributes. Resize the engineer_shocked.webp from 1024x900 to match its 248x218 display size. Add explicit width and height attributes to all img elements to prevent CLS.

AI Performance Analysis
This website has poor performance with a score of 65/100, indicating significant speed issues that are likely frustrating users. The biggest problem is extremely slow loading times - it takes 6.5 seconds for the main content to appear (Largest Contentful Paint), which is far beyond Google's recommended 2.5 seconds. The primary culprits are render-blocking CSS and font files that delay page rendering by nearly 3 seconds, oversized images that are much larger than needed for their display size, and poor caching settings that force users to re-download the same files repeatedly. Fixing these issues by optimizing image sizes, implementing proper caching, and deferring non-critical resources could dramatically improve the site's performance and user experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+25 points estimatedWhy It Matters:
CSS and font files are blocking initial page render, delaying FCP by 2.85 seconds and LCP significantly.
How to Fix:
Inline critical CSS directly in the HTML head to eliminate the 161ms delay from style.css. Use font-display: swap for Google Fonts and preload the Ubuntu font variants. Consider self-hosting fonts to reduce dependency chain length.
Fix Forced Reflows and JavaScript
Medium Impact+10 points estimatedWhy It Matters:
JavaScript is causing 35ms of forced reflows and 103KB of unused Google Analytics code is blocking resources.
How to Fix:
Move DOM geometry queries (offsetWidth) after all style changes to prevent reflows. Defer Google Analytics scripts using async loading or move to Google Tag Manager container. Remove unused tracking code to reduce JavaScript parsing time.
