How to Speed Up Your WordPress Site? (27+ Actionable Tips)

How to Speed Up a WordPress Site

Wondering how to speed up a WordPress site? Then, you’ve come to the right place. This article lists some useful tips for you to improve the speed of your WordPress site.

It’s normal to prioritize how a website looks when you’re creating one. After all, that’s the first thing a visitor sees before anything else when clicking on your website. But, what if it loads so slow that people will exit leave your page even before they get to see the first piece of content on it?

Bottom line is that along with the design, you should also think of optimizing the site for speed. Already have a fully functional website that’s starting to perform very poorly? Don’t worry, it’s possible to optimize an existing site for speed as well.

This article has tips for both scenarios. So, read ahead to learn what they are and apply them immediately to your website as well.

Why Improve the Speed of Your WordPress Site?

Would you rather use a fast website to read, download, or buy whatever you’re looking for? Or wait for a slow website to load no matter how long it takes? It’s obvious most people would choose the first option.

So, wouldn’t it be the same for your visitors? Yes, a fast website is important to keep visitors on your site. But, what does that entail for you as a website owner? Here are some things you should keep in mind:

  • Good user experience: A good user experience encourages visitors to stay and explore your site longer and return for more resources.
  • Low bounce rate and high conversion rate: In simple terms, visitors are less likely to exit your website before it fully loads and more likely to download or buy something.
  • More traffic and revenue: A low bounce rate because of a pleasant user experience means an increase in traffic. You may also see an improvement in revenue from conversions.
  • Better search engine rankings: Speed has a major role on Google search rankings. So, a fast website will rank higher on search engine page results (SERPs) than a slower one. So, optimizing speed is also improving your WordPress SEO.

That’s why it’s in your best interest to improve the speed of your WordPress site. With that said, here are the actionable tips you can use to do that.


27+ Actionable Tips to Improve Speed of WordPress Site

1. Use a Speed-optimized WordPress Theme

A WordPress theme is a website’s foundation. So, it naturally affects how your website performs in the long run. That’s why it’s wise to choose a theme that is optimized for speed.

This means that the theme has a small file size and sends fewer server requests while loading the theme, decreasing the load time significantly. It isn’t bloated with unnecessary code responsible for slow-loading pages either.

Zakra is the perfect example of a speed-optimized WordPress theme. Kinsta ranked it 7th on their test of the fastest WordPress themes in 2021.


2. Choose a Good Hosting Provider

Similar to a WordPress theme, picking a hosting provider should come before anything else. These providers store all your website data on their web server and make it available for online viewing.

But with so many options available, which one do you choose?

First of all, determine what type of website you’re going to build and what amount of resources you need from your hosting provider. If you’re starting a completely new website from scratch, then you may not need much storage space, bandwidth, etc. for some time in the beginning.

So, for starting a simple blog or portfolio, you can start with a basic hosting plan from one of the best WordPress hosting companies.

But if your site is a high-traffic website, then it’s a good idea to avoid shared hosting since you have to share server resources with other websites. This can degrade your site’s performance whenever those sites experience an increase in traffic.

That’s why in this case, a good hosting option would be cloud hosting or managed WordPress hosting. Both of them guarantee high performance without downtime even during traffic spikes.

Some of the best and popular hosting providers that offer these hosting options are Kinsta, Siteground, and WPEngine.


3. Use a WordPress Caching Plugin

For every visitor who clicks on a site’s link, they’re served its content only after retrieving and assembling all the data stored in the database. The back and forth of requests and data until the page is fully loaded slows down your site drastically.

This problem can be solved by storing a static version of your web pages and serving them to visitors. And WordPress cache plugins do exactly that to improve the speed of your WordPress site. It reduces the requests to the database and consequently, the load time by serving a cached version of your site to visitors.

WP Rocket cache plugin

Some popular WordPress cache plugins backed up by speed tests are WP Rocket, WP Super Cache, and W3 Total Cache. You should check them out if you plan to put this tip into use.


4. Optimize Your Images

Using high-resolution pictures for an attractive website sounds tempting. But they have large file sizes which take a long time to load. The page load time also depends on the format of the images you’re using.

For example, PNG and JPEG files are the most common types of images used on the web. But WordPress has just introduced support for WebP images from WordPress 5.8 update. The WebP images are smaller in size than PNG and JPEG images, hence better for your site speed.

So first of all, you should create images in the right format. Even if you’re using PNG or JPEG images, make sure to crop them in the proper size before uploading any image to your website.

However, that’s not the only way. There are image optimization plugins like Optimole and Smush that automatically optimize your images for you with lossy and lossless compression.

optimole image optimization

The lossy method reduces image size significantly but also reduces the quality along with it. With the lossless method, you won’t see a dramatic reduction in either the image’s size or quality.

As you become more familiar with these methods, you can decide which level of compression is the best for optimizing your site’s images.


5. Pick premium DNS over free DNS

A Domain Name is a website’s address. For example, themegrill.com is ThemGrill’s domain name. With this very name, your potential audience will reach your website and the business it represents. So, you must get a good domain name for your website as well.

When registering a domain name, you can choose either a premium or a free DNS (Domain Name System). Now, those on a tight budget might go for the free option. But, we recommend choosing a premium one over that since they’re faster, more reliable and offer better security.

Premium DNS is not included as part of most domain services but you can purchase it as an additional service with all the best domain registrars.

For example, you can get premium DNS service at Namecheap, GoDaddy, etc.


6. Minify CSS, HTML, and JS files

You can improve the speed of a WordPress site by minifying its HTML, JavaScript, and CSS files. The process of minification reduces the file size by removing unnecessary spaces, line breaks, and comments.

On top of that, you can combine these files to reduce the number of HyperText Transfer Protocol (HTTP) requests. This eliminates the need for separate calls to the server for each CSS and JavaScript file. And the decreased requests cause your site to speed up.

minify CSS, HTML, JS

Most caching plugins like WP Rocket and WP-Optimize provide settings for minification. So, you can just enable the minification feature in the cache plugin you’re currently using or plan to use.


7. Setup a CDN

Every time a visitor clicks on your website, its contents are fetched from the main server. Now, this is a big problem for a global company with target audiences in every part of the world. The further they are from the main server, the slower your website loads for them.

For example, Asian visitors won’t enjoy the same page speed as American visitors if the server is located in the USA.

To eliminate this problem, you can use a Content Delivery Network (CDN). It has multiple servers distributed across the globe that store a cached copy of all your website data.

So, the request for this data goes to the server nearest to the visitor instead of the main server. This directly improves your WordPress site’s speed for visitors from any region.

KeyCDN how to speed up wordpress site

Stackpath, Cloudflare, and KeyCDN are some of the most trusted CDNs you can use. Refer to this article for a more detailed guide to the best CDN services for WordPress websites.


8. Implement AMP on your site

Not considering the speed of your website on mobile devices is the last thing you want to do. Mobile users are just as impatient, if not more when it comes to page speed. So, to increase the speed of a WordPress website on mobile devices, you can use Accelerated Mobile Pages (AMP).

Basically, AMP boosts page speed by limiting the use of HTML, CSS, and javascript on a mobile site. And the best way to implement it on your site is to use an AMP plugin. This will give your SEO a boost as well as provide a great user experience for mobile users.

9. Regularly update core WordPress

Updating WordPress regularly is the best practice for all users. These updates come with bug and security fixes. So, putting off updating your WordPress can cause your website to be slow and vulnerable to security attacks.

To check whether you have the latest version of WordPress or not, go to your Dashboard’s Updates section. If you’re using an outdated version, then immediately install the latest version of WordPress.

update WordPress

For the step-by-step procedure, please check our guide on how to upgrade your WordPress site, themes, plugins to the most recent version.


10. Update Theme and Plugins timely

Similarly, along with WordPress core, the themes and plugins you’re using should be updated too.

In the Updates section, you’ll see a list of all the plugins and themes with new versions. It’ll also tell you whether the plugin’s new version is compatible with your current version of WordPress. You can select them and update them in bulk for ease.

update plugins

One crucial thing to remember while updating a theme is that any customizations you’ve made to the theme will be lost in this process.

To avoid this, use child themes while customizing the WordPress theme you’re using.

As mentioned above, check our detailed guide on update your WordPress, themes, and plugins.


11. Fewer Plugins are Better

The more isn’t always the merrier. With every plugin you’re installing and activating, you’re also adding more code for the browser to load. So, with every needless plugin you add, you’re reducing your WordPress site’s speed.

For example, you may be using multiple plugins that do the same thing as in the image below. Cachify, Breeze, and Cache Enabler are WordPress cache plugins. You don’t need all of them when one will do the job just fine.

plugins how to speed up wordpress site

You may also be installing lots of plugins to add different features, when you could just be using a single multipurpose plugin offering said features together.

That’s why it’s important to sort through plugins you’re using or plan to use and keep only the necessary ones. The fewer the plugins, the better your WordPress site’s page speed performance.

12. Remove Unused Plugins from Your Site

So, what should you do with all the unnecessary plugins that are cluttering up your site? It’s best if you uninstall and delete the plugins altogether. Just deactivating inactive plugins won’t work since they still bloat your database with stored data.

To do this, go to your WordPress Dashboard. Then, click on Plugins. Here, Deactivate and Delete all unused plugins.

delete plugins

But this still may leave behind tables of the plugin data in the database. To get rid of it completely, you’ll either have to manually clear these tables or use a database cleaner plugin like Advanced Database Cleaner.


13. Avoid Hosting Videos on Your Site

WordPress has the option to directly upload a video from your media library or computer. But this is not ideal for your website’s speed.

What you’re doing is hosting big video files on your site. In addition to the slow performance, you’ll have to pay your web hosting provider large fees based on the video bandwidth use.

Instead, you can host all your videos on third-party hosting platforms like Youtube and Vimeo. Then, use the video embed feature of the WordPress block editor and paste your video’s link to add it to the page. Simple as that!

14. Implement Lazy Loading for your Images

Not every image on your website needs to load at the same time. This will only slow down a page’s loading time unnecessarily. It’s better to prioritize images that are visible to visitors immediately over ones at the bottom of the page.

Lazy Loading is the perfect solution for that. The images on your website will load as a visitor navigates across its different parts. This, in turn, improves your WordPress site’s speed.

lazy loading how to speed up wordpress site

The Lazy Load feature is available in a lot of cache plugins like WP Rocket and image optimization WordPress plugins like Smush. So, you can just use one of them instead of using a separate lazy loading plugin.


15. Turn off Pingbacks and Trackbacks

Pingbacks and trackbacks are mechanisms made to alert you when another site links to your posts. This poses a big problem to sites that receive many pingbacks and trackbacks. It creates needless strain on your server’s resources because every link generates individual requests.

When that happens, your website’s load time suffers. So, the best solution is to disable pingbacks and trackbacks.

For that, go to Settings on your Dashboard and click on Discussion. Uncheck the Allow link notifications from other blogs box and Save Changes.

pingbacks and trackbacks

16. Paginate Blog Posts and Use Excerpts

Too many blog posts loading on a single page makes your website slower. You can solve this problem in two ways.

First, if you plan to include blog posts on your home page, you should only display excerpts of the posts instead of the whole thing.

To do this, go to your Dashboard and click on Settings. In the Reading section, set For each post in a feed, include: to Summary which is Full Text by default.

blog excerpts

The second method is to paginate blog posts. In the same settings, you can define how many blog posts a page should display initially.

paginate blog posts

Let’s say you set it to 10. So, to explore more than 10 posts, your visitors will have to click on a button that will load more blog posts.


Hotlinking is when another website directly links to your website’s media files like videos, images, and infographics.

This practice negatively impacts your WordPress website speed by increasing HTTP requests and load on your web server. Add to that the cost of additional bandwidth and resource consumption.

So, what can you do to prevent this and improve your WordPress site’s speed?

  • One option is to use CDNs like Cloudflare with built-in hotlink protection. 
  • You can also enable hotlink protection with the .htaccess file.
  • Some plugins such as All In One WP Security & Firewall provide hotlink protection.
  • Another way is to disable the right click for your visitors so that they cannot copy your URL. This can be done with a plugin called Prevent Content Theft.
  • Or you can simply change the link of your media files which will display a ‘404 Not Found’ error for the hotlinking party.

18. Limit the Use of Widgets and Social Buttons

Similar to plugins, cramming your website with unnecessary widgets and social buttons does more harm than good. They increase the number of data requests to your database resulting in slow page speed.

limit widgets and social buttons

So, add only those widgets and buttons that are compulsory for your niche.


19. Paginate Comments Under Blog Posts

A few comments under blog posts aren’t that big of a problem. But when you have multiple discussions with hundreds of replies under a single blog post, this can start slowing down your site.

Instead of loading every comment on a single page, you should paginate the comments as you would with blog posts.

Go to Discussion on the Settings page. Enable Break comments into pages and then change the number of comments per page. Don’t forget to Save Changes when you’re done. 

paginate comments

20. Use the Latest PHP version

Newer versions of Hypertext Preprocessor (PHP) offer improved performance for a WordPress website. So, you must update it to the latest version available.

If you’re not sure about which version you’re using, you can check it on the Dashboard. Click on Site Health in the Tools section.

As you scroll down to the recommended improvements, you’ll see a suggestion telling you to upgrade the PHP version. It clearly shows which version you’re using as well.

latest PHP

However, you can’t upgrade PHP from the WordPress dashboard. Since PHP runs on the server, you’ll have to use your web hosting provider to upgrade it to the latest version.


21. Optimize your website’s database

Out of every piece of data stored in the database, there may be some that you no longer have any need for. With all this useless information bloating the database and delaying requests, your WordPress site is bound to slow down.

That’s why it’s important to optimize your site’s database. You can do this by manually cleaning up the database regularly. Or, you can use a cache plugin or database optimization plugin to do the job for you.

optimize database how to improve speed of wordpress site

Advanced Database Cleaner and WP-Optimize are some of your best options.


22. Enable HTTPS and keep your website secure

We know that HTTP is used to transfer data between a browser and a website. HTTPS is the secure version of this protocol which uses encryption for a safe data transfer. Websites using HTTPS display the lock icon in their URL.

enable HTTPS

The good thing about this protocol is that you’re protected from online security attacks that affect your website’s performance. A Distributed Denial of Service (DDoS) attack is one example of this.

And that’s not all. Visitors trust secure sites more than non-secure ones. So, you may see an increase in traffic and conversions. It will also help your site’s SEO since Google favors HTTPS pages over HTTP.

That’s why you should consider enabling HTTPS for your website. How do you do this?

  • First, pick a hosting provider which gives you a dedicated IP address.
  • Buy an SSL certificate from your hosting provider and activate it.
  • After that, install this certificate on your server.
  • Update your WordPress website to enable HTTPS.
  • Redirect your visitors from HTTP to HTTPS pages when necessary.

For more detailed instructions, please check our article on adding SSL and HTTPS to your site.

Not sure about spending money on an SSL certificate? Try web hosting providers like Bluehost that offer free SSL certificates with all dedicated hosting plans.


23. Add Expire Headers

You can define how long a visitor’s browser should display cached content by adding an expire header. Until this designated time, any returning visitor to your website will be served its cached version by their browser. So, these visitors will be able to experience a faster page speed during this period.

Once the expiration time is met, all the old content is replaced by re-downloaded fresh content from the server and stored in the browser cache until it expires again.

It’s possible that the CDN (like KeyCDN and Azure CDN) you’re using automatically adds an expires header to every server request. If not, you’ll need to add them manually or use a plugin like Add Expires Headers.

add expire headers

24. Use HTML instead of PHP when possible

PHP is vital for dynamic website elements like registration, login, e-commerce stores, and more.

But the downside of having unnecessary PHP code in your theme is that it increases requests to the database. As a result of too many requests, your WordPress site’s speed decreases.

This is easily avoidable by replacing PHP codes with simple HTML codes wherever possible.

HTML

HTML doesn’t interact with the database as PHP does. So, the database will have to deal with fewer back and forth requests. Because of this, you’ll see an improvement in your website’s speed.


25. Reduce Redirects on Your Website

A redirect guides a browser from one URL to another. This process obviously consumes time. Even more so when there are too many redirections taking place. So, in order to speed up your WordPress website, you’ll have to reduce the number of redirects.

redirects how to speed up wordpress site

You can use an SEO tool like Screaming Frog to crawl all the links on your website and find out how many redirects you have. Once you do that, delete redirects to dead URLs, fix 404 errors, and remove unnecessary 301 redirect chains.


26. Clean up Your Media Library

There’s a chance you might forget to delete the media files that come with the theme you use for your website. As you continue uploading more images over time, they’ll eat up even more space.

By cleaning up your media library, you’ll be freeing up space in your database. This improves the speed of your WordPress site.

Moreover, the process is quite simple. Just go to your Dashboard and click on Media. All the files in your media library will be displayed here. You can select and delete any file you don’t need using bulk selection.

clean media library

27. Disable, Delete, or Limit Post Revisions

As you’re writing a blog post, your drafts will be saved as a post revision. This feature enables you to recover your old drafts. But too many post revisions will occupy unnecessary database space.

post revisions

So, you can either limit or disable post revisions to increase the load speed of your WordPress website using the following methods:

A. Disable post revisions

First, locate the wp-config.php file in the root folder of your WordPress site. You then need to add this code on top:

define( ‘WP_POST_REVISIONS’, false)

This code prevents any post revisions from being stored in the future.

If you would like to enable your post revision, simply replace the code with this:

define( ‘WP_POST_REVISIONS’, true)

B. Delete post revisions

  • You can delete your post revisions using WP-Optimize or similar plugins that perform database optimization.
  • You can also use a SQL query to do this. Go to phpMyAdmin, choose your database, and run this query in the SQL section.
delete post revisions

C. Limit post revisions

In case you need some post revisions, you can just replace the true or false value in the above code with a number.

define( ‘WP_POST_REVISIONS’, 5)

After this, WordPress will save a maximum of 5 post revisions.


28. Disable automatic updates

WordPress runs background update checks for your installed theme and plugins without your knowledge. It’s a good thing that it’ll alert you as soon as a new version of a theme or plugin is found.

But the glaring drawback is that since these background checks are happening in regular intervals of time, it slows down your admin dashboard. You can easily solve this by disabling automatic updates with plugins like Easy Updates Manager and Disable All WordPress Updates.

automatic updates how to improve speed of wordpress site

Now, this doesn’t mean you can neglect regular updates. Remember to deactivate such plugins weekly and check for new updates manually.
