Let’s see the ten proven strategies for WordPress speed optimization. 

1. Choose A Good Web Host

The first and most important factor in your website’s speed is the web host you are using. No matter how much you optimize other parameters, if your web host does not deliver speed, then you won’t benefit much from your efforts. 

What is a good web host? And how to choose one? For WordPress websites, we recommend using a high-performance Managed WordPress Host. Managed WordPress hosts specialize in providing premium services to WordPress websites. Maintenance, speed, and security are the three most important areas addressed by managed WordPress hosts. Which Managed WordPress hosting should you choose? We recommend Nestify managed WordPress hosting as it offers lightning-fast speed powered with AWS.

Whichever web host you choose, make sure it performs well on the speed factors we discussed above. Customer service is also an overlooked factor that you must keep in mind. Use free trial periods to check the speed optimization offered by the host. Nestify provides a transparent system that you can assess with the free trial.

2. Choose a lightweight theme

WordPress websites are built with themes. The WordPress theme you use defines the basic framework on which you apply customizations to design a website as per your liking. This basic framework affects the speed of your WordPress website. 

What type of theme should you choose? 

Choose a minimalistic theme. The theme should not be bloated or, in other words, it should not have lots of unnecessary features. The theme should be lightweight and responsive.

3. Use a minimum number of plugins

WordPress has a huge plugin repository that offers a plugin for every need there is. This also means you are probably using a plugin you don’t actually need. Having a lot of plugins for your website can affect the loading time. 

Consider using a minimum number of plugins. If a plugin requires a lot of time to load, replace it with a lightweight plugin. There are many plugins that offer combined functionalities. You can benefit from these plugins and reduce the number of plugins you use. With more plugins, it becomes difficult to keep track of updates. Also, there is a possibility of plugin-conflicts that can negatively impact your website’s loading time. 

Also, check if the plugin is tested with the current version of WordPress you are running. Many times plugins are outdated and no longer work with the latest version of WordPress. Plugin updates also resolve speed and security issues. 

Using a few plugins also offers peace of mind. You can easily find which plugin is causing a problem whenever there is an issue with your website’s speed. Fewer plugins mean less maintenance as you have to focus on fewer updates. It also makes plugin conflicts manageable. Troubleshooting becomes easier. For these reasons, minimize the number of plugins you are using for your WordPress website. 

4. Image Optimization

The most important media on your website is probably images. Whether it is your website’s home page, about page, product page, or the blog page, images are everywhere. Images are visually appealing and attract user attention. They also occupy disk space and affect loading time for any website. Therefore, make sure you optimize images to achieve higher website speed. 

The longer it takes for images to load, the slower your website is. Image optimization helps images to load faster. Fast loading images means faster website speed. There are two factors when it comes to image optimization: Image compression and image resizing. These are the two ways to reduce image size. 

A large image size takes a longer time to load. With image compression, you can reduce the size of the image. The quality of the compressed image depends on how the compression is done. There are two types of image compression: lossy compression and lossless compression. 

In lossy compression, image quality is affected by the compression as some data from the image is permanently removed from the image. Lossless compression, on the other hand, retains all the image data while compressing the image.

5. Minify CSS and JS Files

If you tested your website with Google PageSpeed Insights or GTmetrix, you would notice this parameter: Minify CSS and JS. The number of CSS and JS files on your website affect the website speed. The good news is that you can minify these files. But how do you do it if you don’t have the coding experience? WordPress plugins are there to help you. Let’s have a quick look at a few WordPress plugins that can help you minify CSS and JS files. 

Autoptimize

10 Best Tips for WordPress Speed Optimization

This plugin has more than 1 million active installations. It does a lot more than minifying CSS and JS files. In their own words, “It concatenates all scripts and styles, minifies and compresses them, adds expires headers, caches them, and moves styles to the page head, and scripts (optionally) to the footer. It also minifies the HTML code itself, making your page really lightweight.” In short, it speeds up your website. 

WP Super Minify

10 Best Tips for WordPress Speed Optimization

This plugin stands true to its name. It minifies the CSS and JS files. It combines, minifies, and caches inline JavaScript and CSS files. 

6. WordPress Caching

WordPress caching is a well-known way to optimize websites for speed. When a page is rendered, php and MySQL are used. This uses system RAM and CPU. If many visitors come to a site, the system needs to use lots of RAM and CPU. As a result, the webpage is rendered slowly. In this case, you need a cache system. Caching makes it unnecessary to render the page again and again. The cache system generates a static HTML file and serves it. 

If your web host provides caching, then it’s well and good. However, you can benefit from using a caching plugin. Let’s have a quick look at two of the most popular caching plugins for WordPress.

W3 Total Cache

10 Best Tips for WordPress Speed Optimization

W3 Total cache improves the performance and speed of the website by using multiple tactics. This plugin has more than 1 million active installations. 

The plugin provides caching of (minified and compressed) CSS and JavaScript, caching of feeds (site, categories, tags, comments, search results) in memory, on disk, or on CDN. 

WP Fastest Cache

10 Best Tips for WordPress Speed Optimization

WP Fastest Cache is a very popular caching plugin. It has more than 1 million active installations. This plugin is very easy to set up. Also, you get a lot more control over caching. You can block the cache for a specific page or post with Short Code. You can also define the cache timeout. The plugin lets you enable or disable cache options for mobile devices, logged-in users, etc. 

7. Leverage Browser Caching

Leverage Browser Caching means to use browser caching to maximum advantage. Browsers maintain a cache of every website the visitor visits. You can set rules that tell web browsers how to cache your website. These rules can be about the time for which the resources should be stored in addition to how resources can be validated. 

Leveraging browser caching positively adds to the speed of your website. Here is the straightforward guide to leverage browser caching.

8. Using  a Content Delivery Network (CDN)

A CDN or a content delivery network is a network of servers strategically located in different parts of the world. Usually, for a user located far away from the server website hosted on, the loading time will be more. The content delivery network comes to the rescue as it can deliver the content from a server closer to the user location. This results in better loading time. 

Cloudflare is a popular CDN service. You can check with your web host if you get CDN with your hosting account. Nestify provides a free CDN with every hosting plan you choose. 

9. Clean up the Database of your website

It is essential that you regularly clean up the database of your WordPress website. Over time, the WordPress database gets cluttered with a lot of unnecessary data bits. Cleaning up the database, also ensures that only essential things are backed up, reducing the size of each backup.

You can also use plugins to clean up databases.
