What FastMe does
✓Smart Script Delay. Delays heavy third-party scripts like Google Tag Manager, Klaviyo, and Facebook Pixel until user interaction to improve Total Blocking Time and First Contentful Paint.
✓LCP Image Preloading. Automatically detects your storefront's Largest Contentful Paint image for mobile and desktop, then preloads it with high priority for faster perceived load times.
✓Core Web Vitals Protection. Reserves image dimensions to prevent Cumulative Layout Shift, forces font-display: swap, and defers below-the-fold autoplay videos for a smoother visual experience.
