With over 50,000 plugins made for WordPress, It can be over whelming to find good plugins. We listed a select few WordPress optimization plugins that can make your life easier while improving site performance and user experience.

What are WordPress Plugins?

Plugins are small programs that when installed run as part of a WordPress website. They can have their own configuration settings and their interface is integrated within WordPress. You can download them from the official WordPress.org plugin directory or install them directly from within your WordPress dashboard Plugins on the left menu.

Free or Paid WordPress Plugins

There are plenty of free plugins (most cost less than $30). Usually the free plugins offer only part of the paid version, and to utilize all the features and support you need to buy the full version. There are of course very nice plugins that are 100% free and very useful (as we will see below)

Website Speed

Site speed is crucial for good user experience. Given that slow site speeds can frustrate and deter visitors, stop them from returning and negatively affect your Search Engine rankings. Your website speed is something you should not overlook.
A study by ThinkwithGoogle reveals more than 50% of mobile users leave if a website takes more than three seconds to load.

W3 Total Cache

Website speed is not always down to the file sizes and specification of the Hosting account. When files are frequently requested, a cache is built in memory. Serving files from cache can be orders of magnitude faster than trying to pull them all off a hard drive, one at a time. That’s why choosing a cache plugin is one of the biggest optimization steps you can take. W3 total cache is one of has many options for optimizing your website's performance by adding caching and many other techniques that make WordPress load faster. If you combine W3 Total Cache with a powerful managed WordPress hosting package, you will achieve the best performance for your website.

BJ Lazy Load

BJ Lazy Load is one of several lazy loading choices in the plugin directory. Lazy loading is where images below the fold aren’t actually loaded until someone scrolls down the page to where the image is located. This effectively speeds up page Loading Times by not trying to load everything at once, instead relying on a just in time approach. Note that not every lazy load plugin will work with every theme, gallery, and other plug-in out there (there’s 50,000+ possibilities), so set aside a few minutes to test this. Don’t just install and hope! The performance differences can be remarkable, so it’s worth a few minutes of your time.


Automatize makes optimizing your site really easy by optimizing JS, CSS, HTML, Google Fonts and images, async-ing JS, removing emoji cruft and more. Improve your site’s performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site’s specific need.

Broken link Checker

Broken links are not good for SEO or for your users. This plugin will check your website for broken links, create a list of these links and give you a number of options to correct them by either fixing them or removing them. After the initial check, it will also monitor and inform you for any new broken links that require your attention. This is great for search optimization, not page loading speed optimization, but still we are including it for an optimized site.


Taking regular backups of your website can prove to be a life safer, especially when something goes wrong. There are a lot of plugins that do WordPress backups, but one of the simplest and more efficient is the BackWPup. It is simple to set up and configure and can be used to back up both the WordPress database and WordPress folder. Backups must be a key part of the plan when administering a site – especially when installing new features, themes, and plugins.
