Know your Core Web Vitals without leaving WordPress. Cirv Pulse monitors your Lighthouse performance score and tells you exactly what to fix.
Google uses Core Web Vitals as a ranking factor. If your LCP is slow, your CLS is high, or your INP is poor — you’re losing rankings and traffic. Cirv Pulse puts these numbers on your WordPress dashboard with clear pass/fail indicators and fix-it recommendations.
<h4>Why Core Web Vitals Matter</h4>
<ul>
<li>Google ranking factor – CWV directly impacts search rankings since 2021</li>
<li>User experience – Slow sites lose 53% of mobile visitors (Google data)</li>
<li>Conversion rates – Every 100ms of latency costs 1% in conversions</li>
<li>Competitive edge – Most WordPress sites fail CWV (your competitors included)</li>
</ul>
<h4>Free Features</h4>

Easy Critical CSS

Easy Critical CSS is a lightweight WordPress plugin that lets you add Critical CSS to any page on your site to improve loading speed and performance.
Features: 
– Easily add Critical CSS and Secondary CSS to any page 
– Secondary CSS removes unused CSS rules and stylesheets, ensuring only a single optimized CSS file loads 
– Supports posts, pages, archives, and taxonomy pages 
– Fully compatible with caching plugins (WP Rocket, W3 Total Cache, WP Super Cache, etc.) 
– Customizable settings for individual pages 
– Stores Critical CSS in your choice of the database or as static files 
– Optional API service (API key required) for automated Critical and Secondary CSS generation via <a href="https://criticalcss.net/" rel="nofollow ugc">CriticalCSS.net</a> 
– Background processing to generate CSS without blocking page loads or admin actions
<h3>Why Use Critical CSS?</h3>
Critical CSS ensures above-the-fold content loads first by reducing render-blocking CSS. This helps you boost Core Web Vitals, improve page speed scores, and deliver a better experience to your visitors.
Want to try it out first? You can generate free one-off Critical CSS at <a href="https://criticalcss.net/#free-generator" rel="nofollow ugc">CriticalCSS.net</a> and manually apply it to your site using the plugin settings.
