AI Performance Analysis
This WordPress site has poor performance with a score of 67/100, struggling with slow loading times that hurt user experience. The biggest problem is excessive unused JavaScript, particularly from Google Analytics and jQuery, which wastes 125 KiB of data and delays your Largest Contentful Paint by 750 milliseconds. The site takes 5.7 seconds to display its main content, which is far too slow for modern web standards. Removing unused JavaScript code, optimizing images to proper sizes, and cleaning up 19 KiB of unused CSS could dramatically improve loading speeds and boost your performance score by 20+ points.
