Ultimate WordPress Speed Optimization: Core Web Vitals in 2025

  <h2>Why Core Web Vitals Matter</h2>
  <p>Core Web Vitals (CWV) affect rankings, conversions, and user satisfaction. The three KPIs are <strong>LCP</strong> (Largest Contentful Paint), <strong>CLS</strong> (Cumulative Layout Shift), and <strong>INP</strong> (Interaction to Next Paint).</p>

  <h3>Fast Hosting & CDN</h3>
  <p>Start with performance-first hosting. Consider <a href="/get/hostinger" rel="nofollow sponsored">Hostinger</a> or my <a href="/services/hosting-website-services">Managed Hosting</a>. Add <a href="/get/cloudflare" rel="nofollow sponsored">Cloudflare</a> CDN to reduce latency and improve TTFB.</p>
  <h3>Caching & Delivery</h3>
  <p>Use server-level caching and HTTP/2/3. Minify assets and defer non-critical scripts.</p>
  <pre><code># Example: .htaccess caching headers

<IfModule mod_expires.c> ExpiresActive On ExpiresByType image/webp "access plus 6 months" ExpiresByType text/css "access plus 1 month" ExpiresByType application/javascript "access plus 1 month" </IfModule>
