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>

<h3>Deprecated</h3>
This plugin is deprecated and will be removed in the future. 
It was coded back in 2019 when WpRocket did not have asynchronous support for CSS. 
Although this plugin operates at a lower level (main php buffer), which helps apply loadsCSS to ALL styles regardless of whether they conform to wp_enqueue or not, we recommend instead using WpRocket’s system: <a href="https://docs.wp-rocket.me/article/1266-load-css-asynchronously" rel="nofollow ugc">Load CSS Asynchronously</a>.
<h3>Description</h3>
Simple high performance plugin to enhance WP Rocket’s css output to use the loadCSS preload polyfill. 
This will ensure any css being loaded via the page output is deferred, and utilizing a preload [rel] attribute. 
Note: This will not affect admin pages. It’s designed only to process front-end pages.
It is recommended to enable the WP Rocket setting for “Optimize CSS”, which will provide your pages with inline Critical-CSS. 
That way an unstyled flash is not seen on page load (if properly configured of course).
This plugin will boost your <a href="https://developers.google.com/web/tools/lighthouse/" rel="nofollow ugc">Lighthouse</a> and <a href="https://developers.google.com/speed/pagespeed/insights/" rel="nofollow ugc">PageSpeed Insight</a> scores.
<h3>Plugin Mission</h3>
We hope that <a href="https://wp-rocket.me/" rel="nofollow ugc">WP Rocket</a> will implement this as a feature of their plugin. 
The existing <a href="https://docs.wp-rocket.me/article/1266-load-css-asynchronously" rel="nofollow ugc">Load CSS Asynchronously</a> only works for supported wp_enqueue styles, which not all plugins/themes properly utilize. 
For normal users, we recommend using WP Rocket’s system instead of this plugin.
<h3>Requirements:</h3>
<ul>
<li>If you intend for logged-in users to see the effect, you must enable WP-Rocket’s setting called “caching for Logged-In Users”</li>
<li>Alternatively, you can run the plugin without WP-Rocket, despite it’s intended purpose. (>^.^)></li>
</ul>
<h3>Features:</h3>
<ul>
<li><a href="https://github.com/filamentgroup/loadCSS/tree/v2.0.1" rel="nofollow ugc">FilamentGroup’s LoadCSS(v2.0.1)</a> inline injector 
(optional – see settings page next to WP Rocket), triggered via wp_head </li>
<li>High performance Regular Expression approach to process WP Rocket’s (php’s) output buffer, to replace stylesheets with the appropriate loadCSS syntax </li>
<li>Option to enable the buffer processor when you don’t have WP Rocket installed. 
** This will respect AMP pages, and Yoast Sitemap output (by not executing). No other considerations have been implemented. </li>
</ul>
No fluff. Just a robust loadCSS implementation.
You can see how it works, & measure the performance, with this(via repl.it): <a href="https://repl.it/@ensemblebd/WPRocketLoadCSSMeasurement" rel="nofollow ugc">Run the Plugin’s code</a> 
Just paste your own page’s url or html into the appropriate variable @ the top.
And you can test this plugin’s regex as well: <a href="https://regex101.com/r/xsugT7/1/" rel="nofollow ugc">WordPress.com html – links filtered by regex</a>

<h3>Last tested with:</h3>
<ul>

<li>WordPress 6.2.x</li>
</ul>
<h3>Dependencies</h3>
<ul>
<li>WP Rocket (optional via settings) </li>
<li>file_get_contents() php function (if included loadCSS lib is used via options — default = yes)</li>
</ul>
