# Core Web Vitals

In plain words

Core Web Vitals are a set of specific metrics Google uses to measure real-world user experience: loading performance, interactivity, and visual stability. They're a confirmed ranking factor, so poor Core Web Vitals scores can hold back an otherwise well-optimized page.

Example

A page that shows its main content in under 2.5 s (LCP), responds to taps in under 200 ms (INP) and doesn't jump around while loading (CLS) passes all three.

    ## Should I Redesign My Website or Optimize What I Have?

    Optimize if your site's foundation is solid but underperforming in specific areas; redesign if the structure, messaging, or technical foundation is fundamentally holding the business back. A full redesign makes sense when incremental fixes keep hitting a ceiling — outdated CMS, poor mobile experience, or messaging that no longer matches your business. If the core is sound, targeted CRO and content improvements are faster and cheaper than starting over.

    ## Why Is My Website Not Ranking on Google?

    Your website likely isn't ranking due to a combination of thin or irrelevant content, weak technical SEO, slow load speed, or a lack of quality backlinks pointing to your site. Run a technical audit first — broken links, missing metadata, and slow pages are common and fixable quickly. If technical health is solid, the issue is usually content: not enough pages targeting real search intent, or content too generic to compete with more specific pages.
