FAQ

Speed Optimization & Core Web Vitals FAQs

Can you guarantee a 100/100 score?

No honest developer can guarantee a perfect score — Shopify’s own checkout scripts and essential apps have a cost. We do guarantee measurable improvement, and most stores see major gains.

Will optimization break my store?

All work is done on a duplicate theme and fully tested before publishing, so your live store is never at risk.

Why does speed matter for sales?

Faster stores keep shoppers engaged. Industry studies consistently show conversion rates drop as load time rises, especially on mobile.
