Why Speeding up Your WordPress Website is Important

As we spend more of our time consuming content our attention spans have dropped significantly. We’re constantly seeking out the next tidbit of information, lingering only a few seconds before moving on to the next thing.

As a website owner, this means you have hardly any time at all to grasp peoples’ attention and convince them to stay on your site.

If your website is slow people might even leave your website before it loads and this can result in a loss of conversions. What this means is losing people who might purchase your products or sign up for your mailing list.

What’s more the majority of search engines like Google have started acting against slower websites by pushing them further down in search results, meaning even less traffic.

So if you really want to increase your site revenue, traffic, and subscribers, you need to speed up your WordPress website now.

Check Your WordPress Website Speed

Before you embark on doing anything about your site speed you should find out what the speed is at the moment. That way you can compare it to another test when you’ve made your site faster and take note of the improvements.

A super-easy way to test your site speed is to use IsItWP’s WordPress speed test tool. It’s a completely free tool that lets you establish the speed of your website.

Is It WP Check your WordPress website speed.

When you have your results write them down or take a screenshot for future reference.

In general, a decent website page speed is under 2 seconds. But if you can make it even a few milliseconds faster it will make all the difference.

Before we move on, what actually makes your WordPress site so slow? We’ll discover that next!

Why is Your WordPress Site so Slow?

One of the useful things about running a speed test is the results will give you some suggestions on how to make WordPress faster. This, in turn, helps you identify what’s been making it slow in the first place.

Page speed improvement suggestions

The problem is a lot of those suggestions are technical and not easy to understand for beginners. How about we look at what can make your site slower in language that anyone can make sense of?

The main reasons why your website is slow could be:

  • Web hosting – A hosting server that isn’t configured properly can impact your website speed.
  • WordPress setup – Ideally your WordPress site should be serving cached pages otherwise it can overload your server resulting in crashes or slower speeds.
  • External scripts – Scripts like font loaders and advertisements can also hurt your page speeds significantly
  • Page sizes – Usually this refers to the size of images on your website that aren’t properly optimized for the web.
  • Poor quality plugins – Plugins with poor code can slow down your website and put it at risk of a security breach.

So now we know what can cause your website to be slower than usual it’s time to find out what you can do about it.

How to Make Your WordPress Site Faster

You might think it’s difficult to make your WordPress site faster. But the truth is the steps towards getting a faster website are actually quite simple. The key is knowing what steps to take.

Luckily we’ve got the most important ways to speed up your WordPress website explained in detail below. And don’t worry there’s no complicated tech-speak!

1. Install a Caching Plugin

The thing about WordPress pages is that they’re adaptable and put together on-the-fly whenever someone visits your website post or pages.

WordPress needs to run a special process to find the information needed and to put it all together to your visitor. But that process has a lot of steps and if there’s more than 1 person visiting at a time it can slow your website down.

Using a caching plugin can remove some of those steps and speed things up for your website.

Caching works by making a copy of a web page after the first time it loads and then shows that version to every visitor after that.

There’s a lot of good quality WordPress caching plugins available, many of which you can find in this guide. Plus installing a caching plugin isn’t that difficult as is highlighted in this guide to installing WP Super Cache.

You might find that many web hosting companies offer caching which removes the need for you to use a plugin. And if you have managed WordPress hosting you won’t need to do a thing because caching is built-in and turned on by default.

2. Optimize Your Website Images

Optimize your website images to speed up your wordpress website

There’s no denying that images are a vital part of any website. But if they’re not optimized properly for the web they could be one of the key reasons why your site is running slow.

When you take a picture from your phone, camera or stock photo site the file sizes can be pretty huge. And if you upload them to your site without editing them for the web it can put a significant burden on your site speeds.

The best thing to do is to edit and resize your images before adding them to your WordPress media library. You should also choose the right file type too. Usually, this is either a JPEG or PNG.

A PNG image format isn’t compressed which means the image data hasn’t been made smaller. When you compress an image it loses some of that data. Therefore, an uncompressed image will be of higher quality but a larger file size as a consequence.

On the other hand, a JPEG is a compressed image that reduces the image quality resulting in a smaller file size.

To make it easier to choose between the two you should ideally use a JPEG for images with lots of color and detail and PNG for simpler images or those with a transparent background.

To edit your images you can use image-editing software like PhotoShop and GIMP and you can learn all about optimizing images for web performance in this guide. You can also edit and resize images in WordPress which we show you how to do here.

3. Keep WordPress Updated

Something that new site owners might not see as important is keeping their installation of WordPress up-to-date along with any WordPress plugins and themes.

Updating WordPress

To add new features, fix security issues, and address bugs WordPress is updated open. As a website owner, it’s in your best interests to keep everything up-to-date. Not doing so can make your site slow and expose it to security threats.

4. Optimize Processes Running in the Background

There are usually processes that run in the background of a WordPress website. Some of these scheduled tasks include processes like:

  • Backups carried out by a WordPress plugin.
  • Publishing scheduled posts.
  • Automatically checking for updates.
  • Crawlers and search engines fetching content.

Simple tasks like checking for updates and scheduling posts won’t have much of an impact on your website speed. But background tasks like backups and search engine crawling can slow your WordPress site down.

To combat this, ensure your backup plugin runs at a low traffic time and adjust how often your data is backed up.

For example, you could be running backups every evening 7 days a week when you only publish new content on a Tuesday and Wednesday morning. This makes those extra backups unnecessary.

In terms of your site being crawled often you should keep an eye on this in Google Search Console. This is because crawls that result in errors can make your website slower.

If you’re not sure how to use Google Search Console this guide will show you everything you need to know.

5. Use Post Excerpts on Your Homepage/Archives

When it comes to your blog posts WordPress displays the full content on your Hompage and Archives by default. This means that your homepage and other pages like categories and tags will load slower.

Homepage layout with excerpts

What’s more, showing your full blog posts on the homepage makes it less likely that visitors will click through to the actual article. This can reduce how long they stay on your site and your total page views.

To speed up your page load times to can have your site display an excerpt instead of a full-post in WordPress.

Display a post summary in wordpress

To do this go to Settings » Reading in your WordPress dashboard and next to where it says For each post in a feed, include click the Summary option.

6. Use a Content Delivery Network (CDN)

Using a CDN for your website can speed up WordPress loading times for all your visitors wherever they’re browsing from.

A CDN is a collection of servers all over the world which stores static files used to make up your site.

This includes files that don’t change like:

  • Images
  • JavaScript
  • CSS

Which are unlike your dynamic WordPress pages as we explained earlier.

When anyone visits your site when a CDN is in place static files are displayed from whichever server is closest to them. And it will speed up your web hosting server by doing a lot of the hard work for it.

For suggestions on the best WordPress CDN services take a look at this detailed guide.

7. Host Audio/Video Files Somewhere Else

While it’s possible to upload your audio and video files to WordPress it’s not a good idea to do so because it can eat up your hosting bandwidth. Using a lot of bandwidth can cost you a lot in overage fees and some hosting companies could even shut you down as a result.

Alongside this, hosting audio and video files on WordPress can greatly increase the size of your backups making it harder to restore your site if you need to.

Host video files in YouTube

An alternative is to host your video and audio on services like YouTube and SoundCloud, etc., and let them shoulder the bandwidth for you.

That way you can easily embed videos in WordPress without having to sacrifice your page speeds.

8. Split Comments into Pages

Having lots of comments on your WordPress site is a great way to show that you have an active and engaged audience. But displaying all of those comments can make your site slower.

The good news is there’s a solution right within WordPress to combat that.

All you need to do is head to Settings » Discussion from your WordPress dashboard and simply check the box next to where it says Break comments into pages.

Break comments into pages

9. Use a Speed Optimized WordPress Theme

Speed is an important factor to consider when choosing a WordPress theme for your site. It’s tempting to go for the best-looking design with all the stylish features you can find. But the truth is many of those impressive-looking designs are poorly coded and will make your site run super-slow.

When choosing a WordPress theme, simple is usually best. After all, you probably won’t need all those detailed layouts and flashy animations. And if you do you can add them in later.

Opt for a quality WordPress theme from a premium theme shop like:

All of these stores offer well-coded themes that are both beautifully designed and optimized for speed.

Before changing your WordPress theme it’s important to know how to redesign your website without losing SEO which we explain in full here.

10. Utilize Faster WordPress Plugins

The same problems arise with WordPress plugins too. Many plugins are bloated with unnecessary features and code that’s poorly written which all contributes to slowing down your website and impacting page speeds.

To figure out if a plugin is going to hurt your site speeds run a page speed test both before and after installing a plugin. That way you can compare what the impact will be.

We often publish showcases of the best WordPress plugins on the market. And to help you make an informed choice we always ensure we pay particular attention to the following aspects:

  • Ease of use.
  • User experience.
  • Plugin performance.
  • Code quality.

11. Turn Long Blog Posts into Pages

It’s often the case that the longer and more detailed your blog posts are the higher they’ll rank in search engines. But long-form articles with lots of images could actually hurt your page loading times.

One way around this is to split your WordPress posts into multiple pages so that everything isn’t displayed all in one place.

Thankfully there’s an easy way to do this in WordPress. All you have to do is add the following tag into an article where you wish to split it:


You can repeat this on again to have more pages for that particular post.

Long blog post split into multiple pages

Alternatively, why not consider breaking longer articles down into a multi-part series. That way you can publish shorter blog posts more frequently without hurting your page speeds.

12. Optimize Your WordPress Database

Chances are if you’ve had your WordPress site for a while the database will have a load of information you no longer need to keep. Removing this information can improve your site performance quite a bit.

Optimize your wordpress database to speed up your wordpress website

The WP-Sweep plugin is a free and simple way to optimize your WordPress database. It easily lets you clean up trashed posts, unused tags, and optimize the structure of your database with a few clicks.

13. Limit Post Revisions

While we’re on the subject of cleaning up unwanted information in WordPress post revisions are another area that’s usually overlooked. And post revisions tend to take up space in your database too.

What’s more, some WordPress users think that post revisions can affect database queries run by some plugins. If the plugin doesn’t exclude revisions it can slow your site down by looking through revisions without needing to.

WordPress post revisions

It’s quite easy to limit how many revisions WordPress keeps of each post. All you have to do is add this single line of code to your wp-config.php file:

define( 'WP_POST_REVISIONS', 4 );

If you’re not comfortable editing your site files yourself ask your website developer to do this for you.

Once implemented this code limits the number of articles and page revisions to 4 discarding all older ones automatically.

14. Prevent Hotlinking

A guaranteed sign that you’re creating quality content is that soon or later someone will steal it. This might seem flattering but it damages your reputation and overlooks all of the hard work you’ve done.

Sadly one of the ways people do this is by displaying one of your images on their own website by linking to your original image all without uploading it to their own servers. By doing this these people are stealing your bandwidth and you don’t get any of the traffic to show for it.

To block people from hotlinking to the images on your website add this code into your .htaccess file:

#disable hotlinking of images with forbidden or custom image option RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)? [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)? [NC]
RewriteRule .(jpg|jpeg|png|gif)$ – [NC,F,L]

And be sure to change to your own domain name.

15. Use Lazy Loading

As we mentioned earlier in this article having a lot of images in your posts and pages can dramatically impact how fast your WordPress website loads as well as its performance.

The same can be said for websites that are media heavy in general. So if you have a site that relies on a lot of video embeds and photo galleries you could benefit from using lazy loading.

Lazy loading works by downloading only the images that are visible on the screen instead of downloading all of them at once. All of the other video embeds and images are replaced with a placeholder until you scroll down the page to view them.

It’s not just images you can lazy load either. You can also lazy load the following features:

  • Videos
  • Comments
  • Gravatars
  • Iframes

To lazy load your images, videos, and iframes the Lazy Load plugin by WP Rocket is a solid choice. You can also read through this guide to learn how to lazy load comments.

16. Upgrade to the Latest PHP Version

You might already know this but the main programming language of WordPress is PHP. This language is server side which means it’s installed and run on your hosting server.

All of the good WordPress hosting companies will being using the latest most stable version of PHP on their servers. But it’s certainly possible that your host is using an older version.

The latest version of PHP is twice as fast as those before which is a massive boost to the performance of your website if you’re taking advantage of it.

If you’re not sure which version of PHP your site uses you can find out by installing the Version Info plugin. Once you’ve activated the plugin it will show you your site’s PHP version in the footer of your WordPress dashboard.

WordPress PHP version

Should your site be using an older version of PHP you can ask your hosting provider to upgrade it for you. If it turns out they can’t do that it might be time jump ship and look for a new WordPress hosting company.

And that’s it, folks!

We hope this article has helped you learn how to speed up your WordPress website. Now all that’s left is to put these easy steps into practice so you can have a faster website and take advantage of all those extra visitors.
