How to Setup Cloudflare Free CDN in WordPress (Step by Step)

How to Setup CloudFlare Free CDN in WordPress


Do you want to use the free Cloudflare CDN on your WordPress site?

Cloudflare is one of the best WordPress CDN services available in the market. They offer a free CDN that speeds up your website along with a suite of powerful security features for small business websites.

The challenge is that many entry-level users are not able to use Cloudflare because they think it is hard to set up.

In this guide, we will walk you through a complete Cloudflare setup in WordPress to help you improve your website speed.

What Is a CDN?

A CDN or content delivery network is a system of distributed servers that helps deliver your website files faster to users based on their location.

Typically, a web hosting service serves your website visitors from a single location. All the users access the same server, no matter where they are located.

This can cause a delay in content delivery for users living further away from your website’s central hosting server.

That’s why CDNs set up multiple edge servers in different locations around the globe.

These CDN servers cache static content from your website’s origin server and present it to users when they visit your WordPress website.

Content Delivery Network (CDN)

When there is a user request, the CDN server closest to the user’s location will handle it.

For example, if someone in the USA wants to access a UK-hosted website, then a CDN server in the USA will serve that request, not the main server in the UK.

With a CDN, all the user requests are handled by the nearest CDN servers. This reduces the physical distance between the visitors and your website’s server.

As a result, a CDN improves your website performance and speed for all users regardless of their geographic location.

A faster website also improves the user experience and can give your website a slight boost in SEO rankings. Using a CDN also reduces the load on your primary server and protects it from crashing during traffic spikes.

What Is Cloudflare CDN?

Cloudflare CDN

Cloudflare is one of the most popular free CDN providers available on the internet. It is a large network of globally-distributed servers that automatically cache static content and deliver dynamic content quickly.

On top of a CDN service, Cloudflare is also a cloud-based website firewall and a distributed proxy server. It monitors all incoming traffic to your website and blocks suspicious traffic even before it reaches your server.

They offer a free basic plan that’s suitable for small business websites and blogs. They also offer paid plans starting at $20 per month.

Cloudflare is an excellent choice for small businesses looking for a free CDN. However, if you want to fully utilize all of Cloudflare’s features, then you will need the Business plan, which costs $200 per month.

Note: We do not use Cloudflare on WPBeginner. Instead, we use Sucuri as a website firewall and CDN. This firewall has the double benefit of improving speed and security. You can learn more in our comparison of Sucuri vs. Cloudflare.

With that being said, let’s take a look at how to set up Cloudflare Free CDN in WordPress. You can use the quick links below to jump to the different parts of the tutorial:

Setting Up Cloudflare CDN in WordPress

To begin, you need to visit the Cloudflare website and click on the ‘Sign Up’ button.

Visit Cloudflare website

On the next page, you need to enter your email address and password to create a Cloudflare account.

Simply enter the information required, and then click on the ‘Sign up’ button.

Create Cloudflare account

When you finish signing up, you will see a thank you page confirming that your Cloudflare account has been set up.

The next step is to add your website to Cloudflare. You should click the ‘Add a website or application’ button to get started.

The Cloudflare Thank You Page

You can now enter your website into the ‘Enter your site’ field.

Make sure you only type your site’s domain name, such as example.com. You don’t need to type the full URL or any extra characters.

Enter Your Website's Domain Name

On the next screen, you will be asked to choose the type of Cloudflare plan you want.

For this tutorial, we will choose the free Cloudflare plan. Then, click the ‘Continue’ button.

Select Cloudflare free plan

After that, Cloudflare will show you a list of all DNS records their systems found. These will include your subdomains as well.

The DNS records you want to be passed through Cloudflare should have an orange cloud icon. The DNS records that will bypass Cloudflare will have a gray cloud icon.

You need to review the list to make sure that your primary domain is active on Cloudflare with an orange cloud icon. Simply click the ‘Proxy status’ toggle to change the status.

Verify DNS Records to Set up Cloudflare

Once you have verified your DNS records, just click on the ‘Continue’ button at the bottom.

During the next step of your setup, Cloudflare will ask you to update your nameservers. You will be asked to change your nameservers and point them to Cloudflare nameservers.

Change to Cloudflare nameservers

Note: Changing nameservers can take some time to propagate throughout the internet. During this time, your website may become inaccessible to some users.

You can change nameservers from your domain registrar account, like Domain.com.

Or, if you got a free domain from your web hosting provider like Bluehost, then you will have to change the name server by logging in to your hosting account.

For the sake of this tutorial, we will be showing you how to change the nameservers from the Bluehost control panel.

While the process is similar across hosting companies, you can always ask your hosting provider for detailed instructions for their control panel.

Once you are logged in to your Bluehost cPanel dashboard, go to the ‘Domains’ section, and select your domain name. After that, click on the ‘Name Servers’ tab and the ‘Edit’ button.

Edit nameservers in hosting cPanel

Next, you need to select ‘Custom’ and enter the nameservers provided by Cloudflare.

Then, click the ‘Save’ button.

Save new Cloudflare nameservers

After that, you need to go back to the Cloudflare setup page, and click the ‘Done, check nameservers’ button to finish the setup.

It will now check your new nameservers automatically.

Check Cloudflare nameservers

That’s it! It will take a few minutes to update your domain nameservers and activate Cloudflare.

Once activated, you will see the success message in your Cloudflare dashboard.

Cloudflare success message

In the meantime, the Cloudflare Quick Start Guide will open automatically, and you can use it to customize your Cloudflare settings. We will show you how in the next section.

Note: The above screenshots show the Bluehost control panel. Your nameserver settings may look different if you are using a different hosting provider.

Configuring Cloudflare With the Quick Start Guide

The Cloudflare Quick Start Guide should have opened automatically after you clicked on the ‘Done, check nameservers’ button above. This setup wizard will help you improve the security and performance of your website.

The first setting is ‘Automatic HTTPS Rewrites’.

Cloudflare Automatic HTTPS Rewrites

This will help you avoid the mixed content error in WordPress. It does this by automatically changing ‘http’ to ‘https’ in the URLs of all resources and links on your site that can be served with a secure ‘https’ URL.

This setting is on by default. We recommend you leave it on and click the ‘Save’ button.

The next setting is ‘Always Use HTTPS’.

Always Use HTTPS

Some users have reported issues when using this setting with Cloudflare. This setting is disabled by default, and we recommend you leave it that way. We will show you how to redirect from HTTP to HTTPS using the All in One SEO plugin later in this article.

Now you can click the ‘Save’ button to move on to the next option.

The next setting is Brotli compression.

Brotli Compression

Cloudflare can use Brotli compression to unlock 15-20% speed improvements. This setting is on by default, and we recommend you leave it on.

Make sure you click the ‘Save’ button to store this setting.

Now you will see a summary of what you have configured with the Quick Start Guide.

Cloudflare Quick Start Summary

You should see:

Automatic HTTPS Rewrites: ON

Always Use HTTPS: OFF

Brotli: ON

You have now completed the Quick Start Guide and can click the ‘Finish’ button. However, there are still some additional important settings that need to be configured.

Configuring Additional Important Cloudflare Settings

Your basic Cloudflare setup is complete, but there are a few essential settings you need to configure to keep your WordPress site secure.

1. Secure Your WordPress Login Page

You can set up page rules to customize how Cloudflare works on specific pages on your site. This is especially useful for securing critical pages such as the login page and wp-admin area.

The Cloudflare free account allows you to set up 3 page rules. If you want to add more page rules, then you need to pay $5 per month for 5 extra rules.

First, you need to click the ‘Rules’ option in the menu on the left of the page. After that, you can click the ‘Create Page Rule’ button.

Cloudflare Page Rules

Now you can set up 3 different page rules. You can start by creating a rule that secures your WordPress login page.

Simply add the following settings below to secure your website:

Page URL: example.com/wp-login.php*

Settings: Security Level – High

Secure WordPress login page

When you are done, just click ‘Save and Deploy’ to store and activate the rule.

2. Exclude the WordPress Dashboard from Cloudflare

You will be returned to the Page Rules page, where you can see your first rule listed.

Now you can create a second rule to exclude the WordPress dashboard from Cloudflare caching and enable high security.

Click the Create Page Rule Button

You’ll need to click on the ‘Create New Rule’ button to create your second rule.

After that, you need to type the following settings into the rule. You can click the ‘+ Add a Setting’ button to add new rows for additional settings:

Page URL: example.com/wp-admin*

Settings: Security Level – High

Cache Level – Bypass

Disable Performance

Disable Apps

Exclude WordPress dashboard

When you are done, make sure you click ‘Save and Deploy’ to add the new rule.

3. Configure SSL Certificate Settings

Another important setting is the SSL certificate available in the ‘SSL/TLS’ menu on the left.

Set SSL certificate settings

Make sure to click the ‘Full’ radio button if you are already using SSL.

If you don’t have an SSL certificate, then see our guide on how to get a free SSL certificate for your website.

Once you are done, Cloudflare will provide the essential green padlock in your visitors’ address bar to signify that your website is secure.

4. Redirect from HTTP to HTTPS Using All in One SEO

We mentioned earlier that we don’t recommend using Cloudflare’s ‘Always Use HTTPS’ feature. A great alternative is to use the All in One SEO plugin. It’s the best SEO plugin for WordPress, used by over 3 million sites.

The first thing you need to do is activate and install the All in One SEO plugin. For more details, see our guide on how to install a WordPress plugin.

After that, navigate to All in One SEO » General Settings and then enter your license key into the ‘License Key’ box and click ‘Connect’.

Enter AIOSEO license key

You can find your license key in your account profile on the All in One SEO website.

Next, navigate to All in One SEO » Redirects and then click the ‘Full Site Redirects’ menu navigation option.

AIOSEO Full Site Redirect

You will need to scroll down the page until you find the ‘Canonical Settings’ toggle. You should click this toggle so that it turns blue.

Next, turn on the ‘Redirect from HTTP to HTTPS’ toggle. This will create a redirect from HTTP to HTTPS, making sure that your visitors always have a secure connection to your website.

Using AIOSEO to Force HTTPS

When you are done, make sure to click the ‘Save Changes’ button at the bottom or top of the screen to store this setting.

Optimizing Cloudflare for WordPress Using a Plugin

Cloudflare offers a dedicated WordPress plugin for one-click WordPress-optimized settings.

The plugin lets you quickly set up Cloudflare on your WordPress site, add web application firewall (WAF) rulesets, automatically purge the cache, and more.

Once done, you need to visit Settings » Cloudflare in your admin panel to configure the Cloudflare settings.

On the settings page, you will see a ‘Create Your Free Account’ button and a sign-in option for existing accounts. Simply click the ‘Sign in here’ link.

Cloudflare plugin settings

On the next screen, you will need to enter your Cloudflare email and API key.

Click the ‘Get your API key from here’ link.

Entering API Credentials Into the Cloudflare Plugin

This will bring up a popup for your account area on the Cloudflare website.

Make sure you are on your ‘My Profile’ page, and then click on the ‘API Tokens’ tab in the left sidebar.

After that, go to the ‘Global API Key’ section and click on the ‘View’ button.

Get global API key

This will open a popup and display your API key.

Simply click on the key to copy it.

Click to Copy the Global API Key

Next, you need to come back to your WordPress dashboard and enter your email address and API key.

Then, click the ‘Save API Credentials’ button.

Save Cloudflare API Credentials in WordPress

After that, the Cloudflare settings will appear on your dashboard.

From here, you can apply a single-click WordPress optimization, purge the cache, enable automatic cache, and more.

To optimize your WordPress site, just click the ‘Apply’ button next to ‘Apply Default Settings’.

Apply to optimize WordPress

Next, click on the ‘Settings’ menu option.

Here you will find more site optimization settings.
