1 W3 Total Cache
W3 Total Cache (W3TC) W3TC is one of the most popular cache plugins for WordPress. One reason for its popularity is that it’s compatible with most hosting plans, including shared, VPS, and dedicated server hosting.
You can also set up an integration with your CDN provider for even better website performance. And, you can test all these configurations in preview mode before deploying them on your website.
W3 Total Cache Pro offers even more functionality, including fragment caching, advanced caching statistics, lazy load for Google Maps, and more.
2 LazyLoad by WP Rocket
Usually when a visitor hits your website and tries to load a page it will load the entire page.
If it’s a long page with lots of images this can cause your loading times to skyrocket.
The truth is that you don’t actually need the entire page to load at the same time, especially images which usually take the most time to load.
The idea of ‘lazy loading’ is that specific elements are only loaded when they are needed. And that’s what LazyLoad by WP Rocket will do.
One interesting feature is that you can replace your YouTube iFrames with preview thumbnails.
- Replaces post images, post thumbnails, etc.
- YouTube iFrames can be replaced with preview thumbnails
WP-Optimize started as a database optimization plugin before morphing into a more full-service WordPress speed optimization plugin that can:
Implement page caching
Enable Gzip compression
It can also still optimize your database, of course.
There’s also a premium version that can:
Schedule database cleanups
Remove orphaned (unused) images
Lazy load images
Optimize individual database tables
WP-Optimize comes from the same team as the popular UpdraftPlus backup plugin, so it’s got a good team behind it.
The free version is available at WordPress.org. After that, the paid version starts at $39 per year.
Just download the plugin, upload it in the directory file and activate it through the ‘Plugins’ menu in WordPress.

While Perfmatters is best known for the script manager to remove unused CSS/JS, it also does bloat removal and optimizes for core web vitals.
Take their remove unused CSS feature which uses the faster method of loading used CSS in a separate file. SiteGround Optimizer doesn’t do this while WP Rocket does but uses the slower inline method. Perfmatters can host fonts/analytics locally, includes browser resource hints (preload, prefetch, preconnect), and has more lazy loading settings than most cache plugins.
The worse job your cache plugin does of optimizing for core web vitals and bloat, the better results you should get with Perfmatters. It also has more features compared to Asset CleanUp.

NitroPack is a one-stop WordPress performance plugin that does the job of several plugins. It’s a one-stop solution that provides everything you need to improve your website performance out of the box. You get caching, image optimization, CDN, and more!
The whole point of NitroPack is to make it easier to optimize your WordPress website. Instead of having to piece together a bunch of different plugins that optimize different aspects of your site, you just install one connector plugin and it takes care of all speed optimizations automatically, with built-in features like:
CDN (Content Delivery Network)
Image optimization stack
Code minification (HTML, CSS, and JS)
World-class speed optimization algorithm
The setup process takes less than 5 minutes, and you won’t have to touch a line of code. Just choose how aggressively you want to optimize your WordPress site and NitroPack will take care of the rest.
In many cases, you’ll see instant results. In fact, NitroPack reports that the average user gets a 69% boost on their PageSpeed Score after installing the plugin. Anecdotally, many users report significant reductions in page loading speeds, from 3 seconds to <1 second. You should also see a boost to your Core Web Vitals—an important set of SEO ranking factors this year.
And don’t worry, despite how comprehensive NitroPack’s feature set is, it’s a lightweight plugin that won’t clog up your resources.
All optimizations are run on NitroPack’s own servers to decrease the load on your end, and it’s fully compatible with all the main page builders, so you shouldn’t run into any plugin conflicts (but always backup your site just in case).
On the whole, we’re incredibly impressed with NitroPack. If you’re looking for an all-in-one speed optimization plugin that gets results, there’s no better solution.
