Site Speed & Performance
Carti + Superspeed
Superspeed is a site speed and performance suite used by over 5,000 Shopify stores. It tunes your storefront automatically and catches revenue leaks like ghost checkouts before they cost you sales.
Why we recommend Superspeed
A fast store helps everything on it convert better, including Carti. Slow pages cost you sales before a shopper ever reaches the cart, and Superspeed keeps your storefront quick without you touching any code. It also finds the quiet leaks, like ghost checkouts and broken links, that drain revenue you never see in your reports. When speed is what's holding a store back, it's the tool we point merchants to.
How it helps your store
- Tunes Core Web Vitals and storefront speed automatically
- Flags revenue leaks like ghost checkouts and broken links
- Built for high-volume Shopify stores
