Cacheability improves your website loading time by making it a well-behaved HTTP citizen.
<h3>Plugin Features</h3>
<h4>Conditional HTTP GET</h4>
Cacheability adds conditional HTTP GET feature for WordPress posts. A repeat request to a post which wasn’t modified, will result in a 304 HTTP response. It quickly tells the browser: “nothing new here” without sending the whole post all over again. This saves the bandwidth and increases performance on both ends.
<h4>Fixes soft 404 errors</h4>
WordPress emits soft 404s on empty search results or an invalid tag page, e.g., either <code>/?s=foo</code> or <code>/tag/bar</code> will always result in the HTTP 200 status code, irrespective of whether any entries were displayed there. Soft 404s are bad for you! Cacheability eliminates them by setting the proper 404 HTTP status upon empty search results or tags.
This improves your SEO ranking.
<h4>Warming cache for updated content</h4>
Every time you edit a WordPress post, your cache is cleared in many places. The post page is cleared, the homepage is cleared, the category, feeds, etc., etc. You edited just a single post or page, but your cache is cleared in many places!
This is cool because you don’t want stale content on your website. But it’s not cool to make your next visitors face slow pages!
Cacheability automatically warms up the pages which were purged from cache:
<ul>
<li>It warms up purged caches as soon as you edit your content, via cron</li>
<li>It warms up both Gzip and Brotli versions of cleared pages</li>
</ul>
All this allows for more happy visitors that hit your cache, and not slow backend!.
This feature requires <a href="https://wordpress.org/plugins/varnish-http-purge/" rel="ugc">Proxy Cache Purge</a> plugin. 
Also, ensure WordPress cron is configured correctly.

Nestify

speedien

This plugin only supports WordPress sites hosted on https://nestify.io. You can signup for a free trial subscription at https://nestify.io
Speedien optmizes your site for best performance on desktop and mobile devices automatically. No coding required. We start by prioritizing resources needed for above-the-fold content and deferring everything else. This helps improve core web vitals metrics automatically and help with search engine rankings.
This plugin enables a high speed global CDN that automatically optimizes site’s static assets, images, and videos. CDN also converts images to WebP format to reduce the file size. Images are automatically resized according to visitor’s screen size.
This core web vitals booster plugin is used to link your speedien.com account and WordPress. After the plugin is installed and activated, your site’s contents are automatically optimized on our cloud servers. These optimized content are then served by WordPress from the cache, which minimizes the response time or TTFB.
This plugin also optimizes your site for marketing campaigns as well as paid traffic or CPC. Usually email marketing campaigns and Facebook or Google Ads add unique query parameters to each visitor’s request. This causes typical cache plugins to bypass cache, making them ineffective in real-world usage. With Speedien, all marketing tags, ad click IDs are automatically ignored and your visitors receive instant response from cache.
This plugin intelligently excludes visitors from cache when they are making any WooCommerce transactions. If you update your site, blog posts, or pages from wp-admin, these pages are automatically removed from the cache and preloaded again with fresh content.
Speedien service includes 24×7 support with 1 hour response time or less. If you run into any issues or need help optimizing your site further, our web performance experts are ready to assist. We also monitor core web vitals of your website each day and send you a report. If your site’s score changes by more than 10 points, it automatically starts a review process on our end.
Using this plugin along with a Speedien.com subscription helps you stay on top of your site’s performance and improve conversions as well as SEO rankings.
