Cumulative Layout Shift

A fast-looking store is not always a fast store.
Shoppers and search engines measure performance differently than your theme preview does.
Core Web Vitals affect rankings
Google uses LCP, INP, and CLS as quality signals — slow stores lose visibility in search.

Analytics, chat, and marketing tags often load before your theme is ready to sell.
Mobile shoppers feel the lag first
Slow networks and older devices expose every unoptimized script and image on your storefront.
Speed problems hide in plain sight
A store can look polished to humans while Lighthouse and PageSpeed Insights show a different story.
