<h4>BENEFITS</h4>
WP Meteor can improve your <a href="https://pagespeed.web.dev/" rel="nofollow ugc">Pagespeed</a> results and the actual loading time of your website by up to 5x! You do not have to take our word for it, it only takes 2 minutes to install the plugin and <a href="https://test.fastpixel.io/" rel="nofollow ugc">test how it improves</a> your website speed. 
And since the plugin is designed to leave no traces on your hard drive or database when deactivated and removed, there is no risk for you.
<h4>HOW IT WORKS</h4>
If the user does not interact with the page immediately, WP Meteor defers loading and firing scripts until the page is rendered, which increases the pagespeed metric, on average, by 2-5x.
This delay in loading scripts greatly improves perceived load times for your visitors. It also significantly improves the following important SEO metrics:
<ul>
<li><a href="https://pagespeed.web.dev/" rel="nofollow ugc">Page Speed</a></li>
<li><a href="https://web.dev/lcp/" rel="nofollow ugc">Largest Contentful Paint (LCP)</a></li>
<li><a href="https://web.dev/tti/" rel="nofollow ugc">Time To Interactive (TTI)</a></li>
<li><a href="https://web.dev/tbt/" rel="nofollow ugc">Total Blocking Time (TBT)</a></li>
</ul>

Let me cut to the chase. WP Meteror is an awesome plugin that actually worked for me and rocketed my score up according to Google Page Speed metrics.
Furthermore, It is fully compatible with Autoptimize and WP Super Cache, two great plugins which I persistently consider among “must-haves.” 
Being always frustrated with GPS scores, I was always looking for a way to minimize the damn “main thread work,” get rid of “render-blocking resources” and improve LCP, TTI and TBT (Ironically, Google still regards its own reCAPTCHA, Tag Manager, etc. as render-blocking or unused JavaScript!)
The optimization of JS files and applying Defer attribute to scripts, among many others, just led to a slight improvement in my score, no way comparable with that of WP Meteor.
Last but not least, using WP Meteor had some downsides on my website as Alex had clearly explained. But there is an inbuilt exclusion session which helped me exclude troublesome scripts easily.
In a nutshell, this plugin kills it on Page Speed and deserves 10 out of 5 stars!

Cacheability makes your WordPress site a better HTTP citizen, improving SEO and cache efficiency.
<h4>Free Features</h4>
Soft 404 Fix
WordPress returns HTTP 200 for empty search results, invalid tag pages, and empty category archives. Google marks these as “soft 404” errors in Search Console, hurting your SEO.
Cacheability fixes this by returning proper 404 status codes when:
<ul>
<li>Search results are empty (<code>/?s=nonexistent</code>)</li>
<li>Tag archives are empty (<code>/tag/nonexistent/</code>)</li>
<li>Category archives are empty</li>
<li>Author archives are empty</li>
</ul>
Smart Cache-Control Headers
Automatically adds <code>s-maxage</code> headers so Varnish, NGINX, and CDNs can cache your pages efficiently without affecting browser caching behavior.
<ul>
<li>Search/404 pages: 1 hour cache</li>
<li>All other pages: 1 year cache (your purge plugin handles invalidation)</li>
</ul>
<h4>Cacheability Pro</h4>
Upgrade to <a href="https://www.getpagespeed.com/web-apps/cacheability-pro" rel="nofollow ugc">Cacheability Pro</a> for advanced features:
