Optimize Hero Image Delivery
High Impact+6 points estimated
Why It Matters
The hero image is 70KB larger than needed and delays LCP by 500ms as the largest contentful paint element.
How to Fix
Resize hero image to match display dimensions (463x823 instead of 682x1365). Convert to WebP format using WordPress plugins like ShortPixel. Add responsive srcset with multiple sizes for different viewport widths.

What This Score Means
A score of 88 falls in the "Needs Improvement" 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 WordPress site has good performance with a score of 88/100, but there's significant room for improvement in user interactivity. The biggest problem is excessive main-thread work (2.9 seconds) caused primarily by style and layout calculations, which is creating delays when users try to interact with the page. The site is also suffering from forced reflows triggered by the GSAP animation library, which causes the browser to repeatedly recalculate page layouts and hurts responsiveness. Reducing unused JavaScript (especially the 76% unused jQuery code) and optimizing the animation scripts could eliminate these bottlenecks and make the site feel much more responsive to user interactions.
Other Optimization Recommendations
Reduce GSAP Forced Reflows
High Impact+8 points estimatedWhy It Matters:
GSAP animations are causing 200ms+ of forced reflows, severely blocking user interactions and degrading Core Web Vitals.
How to Fix:
Optimize GSAP animations by batching DOM reads/writes using requestAnimationFrame. Replace geometric property queries (offsetWidth) with CSS transforms. Consider using will-change CSS property on animated elements to promote them to their own layer.
Remove Unused jQuery Code
Medium Impact+4 points estimatedWhy It Matters:
jQuery library wastes 22KB (76% unused) and adds 150ms to LCP with unnecessary JavaScript execution.
How to Fix:
Audit WordPress theme for actual jQuery usage and replace with vanilla JavaScript where possible. Use Asset CleanUp Pro to conditionally load jQuery only on pages that need it. Consider switching to a modern WordPress theme that doesn't rely on jQuery.
