Core Web Vitals

Core Web Vitals are three real-user measurements Google uses to quantify page experience: LCP (Largest Contentful Paint — loading), INP (Interaction to Next Paint — responsiveness) and CLS (Cumulative Layout Shift — visual stability). INP replaced FID in March 2024.

Reviewed October 5, 2026. Prices are quoted per project; nothing on this page is a published price list.

The three signals

LCP — how long until the largest visible element renders. Good: 2.5 seconds or less.
INP — how quickly the page responds to taps and clicks. Good: 200 milliseconds or less.
CLS — how much the layout jumps. Good: 0.1 or less.

Why they matter for small business

Slow, jumpy pages lose calls and bookings — a trades visitor on a phone in the rain is not waiting for a hero film. Page experience is one input among many; it rarely overrides great content, but it caps how far good content can go.

How we keep pages fast

Hand-written pages, no heavy frameworks, images and videos sized and lazy-loaded with posters, fonts self-hosted, and motion that never blocks the main thread. We measure with real devices before we ship, not after we notice complaints.

Questions

Are Core Web Vitals a ranking factor?

They are part of Google's page experience signals — one input, not a switch. Great content can outrank fast content, but slow pages make everything harder, especially on phones.

What is a good INP score?

200 milliseconds or less is good; over 500 milliseconds needs work. INP replaced First Input Delay (FID) as the responsiveness metric in March 2024.
