One leak of many

A slow site is just one way your store leaks revenue.

01 — How it works

A real measurement, not a guess

We run a real performance test on your URL, read your actual score and Largest Contentful Paint (how long your main content takes to load), then estimate the revenue you'd recover by getting faster.

02 — Why it matters

Speed is money

Studies from Deloitte, Akamai and Google consistently show conversions fall as load time rises — often around 7% per extra second. On a store doing real revenue, that compounds fast.

03 — The fix

How to get faster

Compress and lazy-load images, cut unused apps and scripts, choose a lean theme, and enable caching/CDN. Grab the free Shopify speed-fix checklist above.

FAQ
