Core Web Vitals
Google’s core page-experience metrics: how fast primary content appears, how responsive the page feels, and how stable the layout is.
What does it mean?
Core Web Vitals are three field metrics: LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift). They describe real-user experience — not only a Lighthouse lab score.
They are one ranking factor among many. Faster pages often crawl and convert better — but vitals do not replace good content and technical SEO discipline.
When you should take them seriously
Organic traffic matters
When Google and landing pages drive the business.
Heavy themes and plugins
Often WordPress or page builders that hurt LCP.
Ecommerce and lead forms
Slow interaction and layout shift cost clicks.
You are changing stack
Migrating to Next.js is a chance to bake vitals in from day one.
Short answers
Is a green Lighthouse score enough?
No. Lab scores help diagnosis; field data (CrUX/Search Console) is what Google weighs.
Does Next.js fix it automatically?
It gives you better tools — you still choose images, fonts, and third-party scripts carefully.
What is the typical first win?
Images, font loading, and removing heavy JS above the fold — before you rebuild the whole CMS.

When does it make sense to hire a Next.js agency?
In-house, freelancer, or a Next.js agency — the choice isn’t about prestige. It’s about pace, ownership, and what happens when the product has to live in production for years.
