Top WordPress Plugins for Site Optimization

If you want your website to run smoothly, then you need to maintain it. The problem is that even simple WordPress sites have a lot of moving parts, so keeping everything in top shape can take up a lot of time.

The good news is that there are plenty of plugins you can use to simplify – and even automate – your WordPress optimization efforts. You just have to configure the tools you want to use, and let them work for you in the background.

In this guide, we’re going to introduce you to 12 of our favorite WordPress optimization plugins. Let’s get right to it!

Speed Optimization Plugins

Excellent performance is essential on all websites. That’s why in this section, we’re going to focus on all-in-one plugins that help you speed up your site.

1. Autoptimize

Even the simplest WordPress website usually has several third-party scripts running in the background, as well as additional CSS. Those scripts can add up, slowing down your site’s loading times.

Minification, the process of removing unnecessary characters from source code (like whitespace and newline characters), is one way to improve page load times. Autoptimize helps with WordPress site optimization by minifying certain assets of your site, like CSS, HTML, and JavaScript files.

Simply install the plugin and then checkmark the boxes for the code you want to be minified. You can even add scripts for the code you don’t want to be compressed, as well as control whether or not you want the compressed files in the HTML code header or footer.

2. Hummingbird Page Speed Optimization

Hummingbird Page Speed Optimization offers a ton of functionality, helping you tackle script minification, file compression, and caching. That means Hummingbird can help visitors load your site’s pages much faster.

Overall, Hummingbird is an excellent all-in-one optimization tool. However, be careful not to set up any other caching or minification plugins, since that might cause conflicts.

3. WP-Optimize

All the information you upload to your WordPress website goes into a unique database. Over time, that database can become bloated, which may slow down your site. WP-Optimize is a WordPress site optimization plugin built to help clean up your WordPress database for maximized efficiency. The plugin works to de-fragment MySQL tables as well as remove data like pingbacks, trashed comments, expired transient options, post revisions, and so on.

The plugin offers great control over which areas of your site you want to optimize. You also have the option to run automatic, scheduled cleanups of your site’s database.

It’s worth noting that in our experience, WP-Optimize only has a significant impact on sites with large libraries of content. If you just set up your website, it may not make a huge difference.

The SEO Framework is less popular, but provides you with all the SEO functionality you’ll need. It’s also remarkably lightweight, which makes it well worth considering.

Image Optimization Plugins

One of the factors that most affects your site’s performance is its media. High-quality images tend to weigh a lot, which can slow things down. The following plugins come in handy for optimizing your images.

1. Smush Image Compression and Optimization

According to, images account for 62 percent of a page’s total weight. Therefore, using a plugin like Smush Image Compression and Optimization can make a huge impact on page load times. This plugin takes the image files you upload, and compresses them so they don’t take as long to transmit and display. It can also enable you to optimize images outside your media library, and resize graphics.

What’s more, Smush offers the most user-friendly interface of all the WordPress image optimizers we’ve tried. If you want a hassle-free experience, then it’s worth checking out.

Like our previous picks, ShortPixel Image Optimizer can reduce your image file sizes. However, it supports more file types than the competition, including JPGs, PNGs, GIFs, and even PDFs.

That last one isn’t an image format, of course. However, the feature can come in handy if you share a lot of PDF content through your site.
