Core Web Vitals

Google's three key metrics for measuring real-world user experience on your website: loading performance (LCP), interactivity (INP), and visual stability (CLS).

Why It Matters for Your Business

Core Web Vitals directly impact two things that matter to your bottom line: search rankings and customer experience. A slow, janky website doesn't just rank lower. It loses customers. 53% of mobile visitors leave a page that takes longer than 3 seconds to load.

For Space Coast service businesses, this is critical. When someone searches "emergency plumber near me" at midnight, they're not waiting for a slow site to load. They're clicking the next result.

How Core Web Vitals Works

Google measures three specific aspects of user experience:

Note

The most common Core Web Vitals killer for local businesses? Hero images that aren't optimized. A 3MB photo of your storefront can single-handedly push your LCP past 5 seconds on mobile.

A Viera dentist's office with a fast, stable website (good CWV scores) will rank higher and convert more visitors than a competitor with a flashy but slow WordPress site loaded with plugins. Google measures real user experience, not visual complexity. Fixing CWV scores at the code level is typical technical SEO agency work (image optimization, render-blocking script audits, font loading, layout shift hunts), and it's where most service-business sites have the easiest wins.

Common questions
FAQ

Tap a question to expand.

How do I check my Core Web Vitals scores?
Use Google PageSpeed Insights (pagespeed.web.dev), Google Search Console's Core Web Vitals report, or Chrome DevTools Lighthouse. PageSpeed Insights shows both lab data and real-user data from the Chrome UX Report.
Do Core Web Vitals really affect rankings?
Yes, they're a confirmed Google ranking factor as part of the Page Experience update. However, they're a tiebreaker. Great content with poor vitals can still rank, but when content quality is similar, faster sites win.
What causes poor Core Web Vitals?
Common culprits: unoptimized images, too many third-party scripts (chat widgets, analytics, ads), slow hosting, render-blocking CSS/JavaScript, and layout shifts from dynamically loaded content like ads or fonts.
