CoreWebVitals

LCP, INP, CLS — the metrics that define perceived performance and affect SEO.

Why we need this / what value this brings

Poor Core Web Vitals directly hurt both user experience and SEO ranking.

When to use this

Check before launch and after any significant page-weight or layout change.

How to use or implement this

Run Lighthouse on the highest-traffic pages (storefront, listing pages) and fix the largest offender first (usually LCP from an unoptimized image or blocking script).

Research questions

• Has Localz's storefront ever been measured against these? Worth a Lighthouse pass once there's real content.
