AI Performance Analysis
This Shopify pet store has severe performance issues with a score of 49/100. The biggest problem is an extremely slow Largest Contentful Paint of 23.1 seconds, caused primarily by a lazy-loaded banner image that should load immediately and JavaScript blocking the main thread for 3.4 seconds. The site is loading 4.8 MB of resources with 435 KB of unused JavaScript and poorly optimized images that could save 418 KB. Removing lazy loading from the main banner, adding fetchpriority="high" to it, reducing JavaScript execution time, and properly sizing images could dramatically improve load times and user experience.
