How To Speed Up a WordPress Site in 17 Simple Ways


You have a website running on WordPress – it appears to be working fine, and load times seem ok. All this talk about speed feels like it is being blown out of proportion, so why do you need to spend time on how to speed up a WordPress site? The answer is that the definition of fast is changing.

The beginning of this century saw the dawn of the internet age with dial-up connections and slow internet speeds. Fast forward two decades and the world lives on the Web. People spend hours daily consuming information, news, entertainment, and streaming videos on super-fast broadband or fast 4G or 5G connections on their PCs, tablets, or palm-sized smartphones.

The most popular websites in the world are highly optimized, run on scalable infrastructure, and deliver a great user experience when it comes to website speed and page load times.

The bottom line is that today’s users have high expectations with short attention spans, and if you are running a WordPress website, making sure it is fast is an absolute necessity.

Why is It Important to Speed Up Your WordPress Site?

A great user experience for a visitor to your website is crucial because it means that:

  • Users are more likely to spend more time on your site reading articles if you are a news site or a blog or browsing around your shop if you are an e-commerce portal.
  • Which will likely result in higher conversion rates if you are selling products or recommending them,
  • Or higher ad views and clicks if you monetize your website via Google Adsense or similar,
  • Leading to higher revenue

Even if your website is not revenue-focused, a reasonably fast website is an essential prerequisite today.

The expected webpage load time is 2-3 seconds, and every second beyond that means lesser visitors, lower time spent on the site, and fewer conversions.

The speed of a website is also essential because it is used by Search Engines like Google as a ranking factor and impacts your SEO too. Google calls this Core Web Vitals.

Google uses Core Web Vitals as a signal of the user experience of a website. So if you want your keywords and website to rank higher in the search results and drive more visitors, then the website must score well on core web vitals.

To begin with, you will need to test the speed of your WordPress website and then look at steps you can take to improve its speed.

How to Test WordPress Site Speed

If you already have your WordPress website up and running, getting a baseline of the website’s speed and performance is helpful. To do a WordPress website speed test, you can use the speed testing tools listed below:

Test WordPress Website Speed

They not only provide metrics on the performance but will highlight areas where improvements can be found to make the website faster. With this baseline, you can track improvements in speed as you implement the recommendations in this article.

While conducting performance tests, you should test for both desktop and mobile, the geographical location of the user, and internet bandwidth. The WebPageTest tool allows you to configure all three parameters while running the test. This will enable you to replicate the performance of various device combinations, bandwidth, and user locations to give you a better sense of overall performance.

How to Speed Up a WordPress Site

We can break down what you can do into three different areas:

  • Things you can do while setting up a WordPress website that will give you good speed straight out of the box
  • Best Practices you should follow to keep your web pages light and deliver faster load times
  • Advanced Optimization techniques to fine-tune and speed up WordPress.

In many ways, this is no different from building a car to go faster. You start with a fast car, make it lighter to go faster, and then tune up the engine, suspension, et al., to give it an extra edge. Right? Getting WordPress to work more quickly is not all that different, so let’s dive into how to speed up a WordPress site.

Basics of a Fast WordPress Setup

1. Select a Good WordPress Host

There are two aspects to WordPress hosting – the type of hosting and the hosting provider. When we talk about the type of hosting, it is the server setup and the resources you have access to.

Types of WordPress Hosting

  • Shared Hosting: You are essentially sharing a server with other users. This is the most affordable type of hosting and is excellent for beginners to get started and get familiar with the world of WordPress. Do note that in a shared server, performance can vary depending on the load on the server. If some other user’s website on the same server is seeing a spike, it might affect the speed of your website.
  • Virtual Private Server VPS Hosting: A VPS hosting service is similar to shared hosting, with one significant difference. You get dedicated resources for your account in terms of RAM, CPU, and Storage on the server. This helps insulate and de-link the performance of your website from another user’s website running on the same server. This is more expensive than shared hosting.
  • Dedicated Hosting: Dedicated hosting is the top tier of WordPress hosting and also the most expensive. It is similar to VPS hosting in terms of the service, but you get a dedicated server and are not sharing with any other users. So more resources, CPU, and storage allow you to handle a higher website traffic load while maintaining performance levels.

Hosting Providers

Selecting a hosting provider with a robust infrastructure, reliability, and optimized WordPress performance is essential when setting up a WordPress website.

While choosing a hosting provider, you should also check the available server locations. Ideally, you would want to select a provider with servers close to your target audience. For example, if your visitors are from Asia, hosting your website on a server in the USA is not recommended. It would mean that the web traffic has a longer distance to travel, impacting load times and, ultimately, user experience.

2. Use a Fast or Optimized Theme

Why: Going for a theme with many features or themes with a lot of dynamic content, or one that looks great, isn’t always the best for speed. A theme may look great, but if it has not been coded well or has a lot of code, it will negatively impact the website’s performance.

How: If performance is critical, then going for a lightweight, optimized theme is the best thing you can do. Themes like GeneratePress, Neve, Astra, Sydney, and OceanWP are known for being fast and highly optimized.

3. Cache your Web pages

Why: Caching your web pages is the fastest and most straightforward way to speed up a WordPress site. And if you are on shared hosting, it will make a lot of difference to page load times.

If you don’t have a cache setup, WordPress will build the page on the server side every time a user visits your website and then deliver it to the visitor. Building a web page involves putting together HTML, CSS, and JS elements along with queries to the database, which takes time. And remember, this will have to be done for every visitor. This not only increases load time but also increases the usage of resources on the server.

If you implement caching, the webpages are built the first time, and the completed webpage is stored in a cache. Then, every new visitor is served the page directly from the cache. This eliminates the build process for every visitor, decreases load time, and reduces server usage.

How: You can implement this easily using a WordPress caching plugin like WP Rocket, W3 Total Cache, and WP Super Cache. Some hosting providers also provide caching as part of the plan. All you have to do is turn on the built-in cache feature if it is available.

4. Use a Content Delivery Network CDN

Why: Your server is located in one part of the world, but your visitors could be from anywhere across the globe, especially if your website caters to an international audience. Web page load times will vary worldwide depending on the distance to your server. For example, if your website is hosted on a USA server, a US visitor will see faster load times than someone from Australia.

How: Installing a Content Delivery Network or CDN is the best way to equalize load times for your visitors or users worldwide. As the name suggests, a CDN is a network of servers worldwide that can deliver content to users in that region or location.

A CDN will replicate your website on data centers at multiple locations spread geographically by caching all your static web pages, including images. A visitor to your website will have the pages loaded from the server closest to them rather than your origin server. A CDN, in combination with a caching plugin, can deliver a good speed upgrade to your WordPress website.

Cloudflare is among the more popular CDNs in the market and even offers a free CDN plan. BunnyCDN and Stackpath are other popular options that you should consider depending on your needs.

5. Optimize Images

Why: Images add color to your post and give a visual appeal that is known to help with your reader engagement. But Images also mean that the size of your web page increases, directly affecting page load times.

Images usually account for a significant part of the web page’s size, which means that reducing image sizes will significantly reduce the web page’s size. So, this is a must-do activity while developing or uploading content for your website.

How: There are three ways to reduce the size of the images on your website:

a. Resize your original images for the Web:

Photos look great when they are in high resolution. Unfortunately, a high-resolution image with a good camera will usually be upwards of 4000+ pixels with a file size of 7+Mb or more. Using an image of this size will severely slow down your website.

So the first thing you need to do is to resize or scale down the image for the Web, depending on how you use it on your website.

  • Background Image: 1920 x 1080 px width (16:9 aspect ratio)
  • Full-Width Post Featured Image: 1280 x 720 px width (16:9)
  • Blog post image: 1200 x 675 px (16:9)
  • Logo (Square): 250 x 250 px (1:1)
  • Product Images: 800 x 800 px (1:1)

The image sizes listed above are our recommendations. The size and aspect ratio of images you use may vary, but you should size them in line with the display area on the web page.

Use any photo editing tool on your PC, and resize the images to the correct size.

b. Use Image Formats optimized for the Web:

There are many image formats: JPEG, PNG, TIFF, and WEBP. On Coolfundas, we primarily use JPEG and PNG formats for our images.

JPEG is a lossy image format, meaning the image has a slightly lower quality but a smaller file size.

PNG is a lossless format and is great for images where quality is vital or has a transparent background. However, the file size tends to be higher with PNGs.

TIFF images are great quality-wise, but the file sizes can be massive. So they are not recommended for the Web.

WEBP is a new image format developed by Google intended to replace JPEG. WEBP delivers superior compression with minimal reduction in image clarity and is slowly becoming the new standard for images on the Web.

For most sites, the JPEG format is ideal for all images except those where image clarity is essential, for which PNG is your best option.

c. Compress your Images:

The final step is to compress these images using a tool.

You can do this in two ways:

The first option is to use a tool on your PC/Desktop or an online tool to compress the images before uploading them.

Alternatively, the more straightforward option is to use an Image Optimization Plugin which will do the job for you. Install the plugin, set the image format and compression levels, and the plugin will automatically compress the files as you upload images.

Some popular image optimization plugins are ShortPixel, Imagify, Smush, and EWWW Image Optimizer.

In addition to compressing your image files, optimization plugins can convert and deliver the WEBP format in your web pages instead of JPEGs or PNGs.

6. Paginate Comments

Why: Comments are great. It means that you have been able to engage well with your audience, and your users are contributing to valuable discussions around the topic of your post.

A lot of comments can be a problem from a page load point of view – it is that much more content to load on your page and slows it down. However, the solution is relatively simple.

How: WordPress offers an out-of-the-box feature to paginate comments. Go to Settings > Discussion > Other Comment Settings. Then, select the checkbox for the option “Break Comments into pages with x top-level comments per page….” and enter a value for the number of comments per page (25, 50, etc.).

By limiting the comments, your web page will load only the first page of comments instead of all comments, reducing the web page size and allowing it to load faster.

7. Minimize Plugin Usage

WordPress plugins are a great add-on, giving you the power to add features you need that are unavailable in the core WordPress installation.

Examples: Page builder, Contact form, or a Slider plugin.

But too much of anything isn’t necessarily a good thing. The more plugins you add, the heavier your website, and if the plugin is not efficiently coded, it’s more bloatware.

So your approach to plugins needs to be two-fold:

  • Avoid adding plugins for features that are nice to have. Limit plugins to features you need and add value to your website. Remove the rest of the plugins from your WordPress installation, if any.
  • Install or use plugins with quality code or lightweight. This will not be apparent to most of us. Your best bet is to research the feature you need (must have) and select plugins that are highly popular or come from well-known plugin developers.

8. Minimize Third-Party or External Scripts

Why: Third Party or External scripts are typically Javascript, CSS, font files, etc., stored on a third-party server and not on your website. These could include Google Analytics, Facebook Pixels, Twitter, Adsense, Disqus Comments, etc.

The more third-party scripts you need to make requests to, the slower your website.

How: Most of these scripts will be invoked by plugins, so the best thing you can do here is to limit or minimize the plugins you install to only those necessary.

9. Keep the Website Updated

On the face of it, this might not appear to impact your WordPress speed significantly. However, WordPress is an open-source project, and features or bug fixes are continuously released. It is in your interest to keep the website up to date to maximize performance and security.

This applies to WordPress Core installation, Themes, and Plugins. You can take advantage of the auto-update feature or update manually on a periodic basis. Please ensure you back up your WordPress installation regularly (to use for restoration if an update breaks your website).

10. Simple or Minimalist Web Page Design

Keeping the design of your web page simple and minimal is a crucial factor that can help speed up a WordPress site.

Minimalist Webpage Design
Simple or Minimalist Web Page Design

To keep your website simple or minimal, keep the following points in mind:

  • Keep Page elements (Rows, columns, Text boxes, sliders, etc.) to the minimum. If you are unsure you need it, you probably don’t. Fewer elements mean less code.
  • Simplify elements where possible, and avoid nesting elements (elements within elements) as much as possible. More elements mean more code to parse during rendering.
  • If you use a visual page builder tool, it is easy to get carried away designing visually awesome content. It won’t help the speed of the web page. You will need to balance visual appeal and simplicity.

Remember, sometimes less is more.

Advanced WordPress Speed Optimization

11. Optimize Javascript / CSS

Why: The best approach to optimizing Javascript or CSS is to minify them.

But what is minify or minification of Javascript or CSS?

  • When developers write code, they usually add comments for reference or add whitespace and line breaks to make the code readable, meaningful variable names, etc.
  • Minification is the process wherein all redundant comments, whitespace, and line breaks are removed from the code. In addition, longer variables are replaced with shorter variables.
  • Minification results in an optimized code with a compact file size, thus improving webpage load times and website experience.

How: You can minify Javascript and CSS using a WordPress plugin like Autoptimize (free) or WP-Rocket (Premium).

12. Optimize the WordPress Database

Why: With time, the WordPress database will grow, and the larger it becomes, the longer it will take for the server to retrieve or query information from the database. The best thing you can do is clean up or optimize your database regularly.

The cleanup process will involve removing comments marked as spam or trash, data from old or unused themes or plugins, revisions, etc.

How: You can obviously clean this manually using PHPMyAdmin to access the database and tables if you are technically inclined, but it can result in issues if not done carefully and properly.

The best way to optimize the database and speed up a WordPress site is to use any of the plugins listed below to complete this task safely and efficiently.

Important: Before manually optimizing the database or using a plugin, please ensure you have backed up your WordPress installation.

13. Limit Revisions

Why: Revisions, as the name suggests, are a copy of the edits you made to a post. Every time you edit and save a post, the previous version remains in the revision history. This gives you the advantage of reverting to an earlier version of your post in case you need to.

While this is a great feature, it also means you can easily build up revision history over time, taking up space and slowing down your WordPress website. The solution is to limit the number of revisions you want to keep for every post.

How: You can limit the number of revisions to store. Let us say you want to store a post’s last 5 (five) revisions at any time. To implement this limit, you will need to access and open the wp-config.php file and add the following lines of code to it:

define( 'WP_POST_REVISIONS', 5 );

If you want to disable revisions completely, add this line of code instead:

define( 'WP_POST_REVISIONS', false);

14. Implement Compression

Why: Using compression for your website is no different than zipping your files on your PC. The purpose is the same – reduce the file size for storage or transmission.

Gzip and Brotli compression are tools that you can use to compress the size of the webpage on the server side, which is then unpacked on the browser end to display to a user.

Using this website compression test tool, you can check if compression is already enabled for your WordPress website.

Brotli Compression Test

How: To enable gzip compression or Brotli, there are a couple of ways to do it:

  • Manually add code to your .htaccess file
  • Use a plugin like WP-Rocket to implement compression.
  • If you are using a CDN, check if it has an option for compression. For example, Cloudflare CDN has the option to activate Brotli compression.

15. Lazy Load Images

Why: Lazy loading images is another technique to speed up a WordPress site. With lazy loading turned on, you only load those images visible in the browser’s viewport for a user. The images are loaded as the user scrolls down the web page.

In short, the initial web page renders with only the visible images giving the user the feeling that the page is loading fast, improving the general user experience of your website.

How: Smush, Lazy Load by Optimole, and Lazy Load Plugin by WP-Rocket are popular plugins you can use to implement lazy loading images for your website.

16. Host Videos on External Video Platforms

Why: Videos are great for any website, adding what can be a useful visual element to a post or a page. The normal way to use a video in a WordPress post or a page would be to upload the video to the media library and add the video to the page or post using a video block.

While uploading a video to WordPress is the default option, there are disadvantages to this approach:

  • Video files tend to be huge in size and take up storage on your hosting server, and
  • More importantly, videos use bandwidth and resources to stream from your host server. Many hosts have bandwidth limits on your hosting plans, and if you have many videos, you will quickly run out of bandwidth and put your hosting at risk of additional bandwidth fees or even suspension.
  • Your backups will also grow in size, making it more difficult to back up your website easily.

How: The right way to handle videos in WordPress is to use a third-party video hosting solution like YouTube, Vimeo, or Dailymotion to upload and store your videos.

After uploading, get the video URL (see example on embed URL for a YouTube video), and use the video embed block in WordPress to add it to a post. By taking the embed route, you avoid stretching your server resources and minimize storage and bandwidth constraints from your WordPress host.

In addition, third-party video solutions are highly optimized for processing and streaming videos and will deliver a faster and better experience for your users.

17. Update your PHP version

WordPress is written in PHP, a server-side language that runs on your hosting server. PHP updates are released periodically that also include optimizations to help WordPress run faster.

It is highly recommended that your WordPress run on the latest stable version of PHP. You can check the latest version on the PHP website.

You can check the PHP version of your WordPress website by going to Tools> Site Health. Select the Info option at the top, scroll down to the Server section, and look for the PHP version.

If you are not running WordPress on the latest stable version of PHP, you should upgrade it. Most hosts will offer you the option to change the PHP version; if you don’t have the option, contact the support team at your host. If your host only offers an older version of PHP, then it is time to change your WordPress host.

Before updating your PHP version, ensure you have a backup of your WordPress installation. If you run into issues, you can always restore from your backup.

WordPress Website Speed Optimization Plugins

Before we wrap up, it is worth pointing out that quite a few of the recommended steps above can be implemented using a speed optimization plugin. With a plugin, you can cache your pages, minify your JS and CSS files, optimize your database, implement compression, lazy load images, etc.

Free and premium plugins are available that effectively deliver these optimizations for you. WP Super Cache and W3 Total Cache are free WordPress speed optimization plugin options, while WP-Rocket is your premium option.

Wrapping Up

If your website is already up and running and you are keen on a quick speed upgrade, installing a speed optimization plugin and a CDN is your best option. But don’t stop here – implementing the rest of the recommendations should still be on your plate and should be taken up.

Selecting the right WordPress host, using a fast theme, a minimal design philosophy, and offloading videos to a third-party host may take time but are well worth it in the long run, and you should get to it when you can.

If you are starting a new WordPress website, everything in this article should be on your to-do list.
