Core Web Vitals
Core Web Vitals, fixed at the cause
Core Web Vitals are three specific measurements of what your visitors actually experience: how fast the main content appears, whether the page jumps around while loading, and how quickly it responds when tapped.
What's included
- LCP: hero content, fonts and server response
- CLS: image dimensions, ad slots and font swap
- INP: JavaScript execution and main thread work
- Field data analysis from Search Console
- Lab diagnosis with Lighthouse and WebPageTest
- Before-and-after reporting on real user data
Why it matters
Google confirmed page experience as a ranking signal, but the stronger argument is commercial: passing Core Web Vitals correlates directly with lower bounce rates and higher conversion, particularly on mobile.
Working with me
Audit first, always
Nothing gets quoted before I've looked at what exists. You get a written scope with what I'd change, what I'd leave alone, and why.
FAQ
Common questions
What counts as passing?
LCP under 2.5 seconds, CLS under 0.1 and INP under 200 milliseconds, for 75% of real visits.
My Lighthouse score is 95 but I'm still failing. Why?
Lighthouse is a lab simulation on one device. Field data comes from real visitors on real connections and devices, and that's what Google uses.
Does this apply to Shopify too?
Yes. Shopify stores fail Core Web Vitals regularly, usually because of app scripts and unoptimised images.
