Implement Responsive Image Sizing
High Impact+25 points estimated
Why It Matters
Images are severely oversized for their display dimensions, wasting 437 KiB and delaying page rendering.
How to Fix
Replace fixed image dimensions with responsive sizes using srcset attribute. Resize the favicon from 960x964 to 48x48 pixels for actual display size. Generate multiple image sizes (320w, 640w, 1024w) and serve appropriate dimensions based on viewport width.
0Poor
What This Score Means
A score of 0 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 0/100, meaning it's extremely slow for users. The biggest problem is that the first content doesn't appear until 8.3 seconds, which is far beyond acceptable standards - users typically abandon sites that take longer than 3 seconds to load. The main culprits are oversized images that are wasting 437KB of bandwidth (like a logo that's 960x964 pixels but displayed at only 52x48) and render-blocking CSS and font files that prevent the page from showing content quickly. Additionally, there are forced reflows in the JavaScript causing 74ms of wasted processing time, which compounds the performance problems.
Other Optimization Recommendations
Optimize Render Blocking Resources
High Impact+20 points estimatedWhy It Matters:
CSS and font files are blocking initial page render, preventing content from appearing quickly.
How to Fix:
Inline critical CSS for above-the-fold content directly in HTML head. Use font-display: swap for Google Fonts to show fallback text immediately. Defer non-critical CSS using media='print' then switching to 'all' onload.
Fix Forced Reflow Issues
Medium Impact+10 points estimatedWhy It Matters:
JavaScript is causing 74ms of forced reflows, blocking the main thread and degrading user interactions.
How to Fix:
Batch DOM reads and writes to avoid layout thrashing. Cache geometric properties like offsetWidth instead of repeatedly querying them. Use CSS transforms instead of changing layout properties for animations.
