How to Setup CloudFlare CDN for WordPress Blog

Using a Content Delivery Network is one of the best ways to reduce page loading time. There are numerous options to choose from, but Cloudflare stands out among the rest because of its exceptional service. What’s great, you can use it for free! Keep scrolling to learn how to set up Cloudflare on WordPress!

What is Cloudflare CDN?

Cloudflare is a Content Delivery Network (CDN) that acts as a proxy between a website and the visitor. This system enables users to receive cached static content from the nearest servers. With shorter physical distance, the site can load faster.

What’s great about Cloudflare is that it has one of the biggest server networks in the world. As such, no matter where your visitors are, Cloudflare will help you deliver the fastest website experience. This surely will help to improve your site’s SEO as speed is one of the ranking factors in search engines.

Compared to traditional CDN, Cloudflare offers many other useful features:

  • DDoS attack mitigation
  • Analytics on all requests made to a website
  • Easy SSL certificate installation
  • Network gateway between protocols

Setting Up Cloudflare on WordPress

Installing CloudFlare on WordPress is a straightforward process. Follow the guide below to know how to do it:

Step 1: Creating a Cloudflare Account

  1. Navigate to the Cloudflare website and click the Sign Up button in order to create an account.

  2. Provide your email and password and then hit Create Account.

Step 2: Adding Domain Name to Cloudflare

  1. Go to your Cloudflare dashboard. Select the +Add Site button below a notification that reads “You currently don’t have any websites.
  2. Now, select your plan. If it’s for a personal site, we recommend you to choose the free plan. Otherwise, choose the Pro or Business plan for business websites.

Step 3: Checking the DNS Records of Your Domain Name in Cloudflare

Once your WordPress site is added to Cloudflare, you’ll be prompted with the DNS details of your domain name. In this step, you can enable or disable Cloudflare for specific subdomains.

To activate, simply toggle the cloud to orange. Cloudflare DNS records

We highly suggest that you enable Cloudflare for your naked domain name and www subdomain. This way, Cloudflare will work on both www and non-www versions of your site.

Once you are done, press the Continue button to proceed to the next step.

It’s not recommended to enable CloudFlare for cPanel, mail, FTP, or any other subdomains as it can result in various DNS issues.

Step 4: Pointing Your Domain Name to Cloudflare Nameservers

After activating Cloudflare for your domain and subdomains, you will be greeted with Cloudflare nameservers on the next page. Now, we need to replace your old nameservers with Cloudflare’s.

  1. Open a new browser tab and visit your hosting control panel. If you’re a Hostinger user, you can find the detail of your nameservers in the Domains tab.

  2. Replace the existing nameservers with those from Cloudflare. Don’t forget to click Update.
  3. Go back to the Cloudflare page and press the Done, check nameservers button.

Note that it may take up to 72 hours for DNS to propagate worldwide. Once the nameservers update has been completed, you will receive an email confirmation message from Cloudflare. Alternatively, you can also check status on Cloudflare website. During this process, your page will not face any downtime.

Step 5: Installing and Configuring Cloudflare Plugin on WordPress

To complete the whole process, we need to install the Cloudflare plugin on WordPress. The tool comes with various handy features to manage the CDN, such as:

  • One-click WordPress optimization
  • Web application firewall (WAF) rulesets
  • Automatic cache purge
  • Statistics
  • Built-in Cloudflare settings for easy modification

Let’s proceed with the plugin installation.

  1. Access your WordPress dashboard and head over to Plugins -> Add New. Search for Cloudflare, then install and activate the plugin.
  2. Go to Settings and select Cloudflare.
  3. Select the get your API Key from here option, located below the log in fields.
    Login page in the settings page of Cloudflare plugin
  4. A window that opens your CloudFlare account will pop up. Go to the API Tokens tab, then, select View from the Global API option.Getting Cloudflare API key
  5. Enter your Cloudflare password, and then copy the provided API key.
  6. Go back to the plugin’s settings page, and paste the key to the login fields. Hit the Save API Credentials button.

After you log in to the Cloudflare plugin, you will see several settings:

  • Optimize Cloudflare for WordPress — enable it by clicking the “Apply” button. It will implement Cloudflare recommended settings for the best performance.
  • Purge Cache — activate this service only after you update your WordPress or website design. This setting will clear all the cached content of your site.
  • Automatic Cache Management — automatically clear all Cloudflare cache every time you switch or edit the theme.


CDN, or Content Delivery Network, is an important service that will help you boost your website speed. Out of so many options, we recommend you to use Cloudflare. It offers a reliable CDN service, as well as security and performance improvements.

What’s cool, you can set up Cloudflare on WordPress for free, as we have explained above. To summarize, here’s how you do that:

  1. Create your Cloudflare account.
  2. Add your domain name to Cloudflare.
  3. Check the DNS records of your domain name in Cloudflare, and then activate the service for your naked and www domains.
  4. Point your domain name to Cloudflare nameservers.
  5. Install WordPress Cloudflare plugin for easy configuration.

That’s it, good luck and enjoy your faster website!

    Hi! I am not able to locate an account with us with your email to see the exact case, but this can occur if you have not added an A record in Cloudflare. A Records are necessary to direct a visitor's browser requests to an origin web server. Access your Cloudflare Dashboard and check if the A record added there is the same as the one in your Hostinger Dashboard. You can see your Hostinger DNS records in your Panel-> Advanced-> DNS zone editor. You will find the A record you need to use there.

    Hey there Salahaddin! Hope you are having a lovely day. Once you set up CloudFlare you may need to tweak few settings based on your DNS configuration, SSL encryption etc. My help is limited via the comments here, but if you message our support team, I am sure they can help you, if your website is hosted here :)

Hi I am getting an error 1000 message. I have checked and the ftp A record is correct. The nameservers I changed both within the domain and hosting. Site launching on Monday - please help!


    Tomislav T.

    Replied on November 06 2020

    Hey there Natasha! :) Make sure to give it 24 hours before your nameservers propagate correctly. After that make sure not only the ftp A record is correct, but the @ A record needs to point to the same IP address as well! Good luck!

Hi! It's a informative guide but I have a query that : Which SSL Certificate we have to activate in it (Hosinger SSL or Cloud Flare SSL) ? Or can we use both at a time ?


    Tomislav T.

    Replied on November 11 2020

    Hey Apurb. You can use both. If you do use both - set CloudFlare's encryption to Full instead of Flexible.

Thanks for the article! I have a question. Is this the same as paying Hostinger SSL ($11.95 ) and Cloudflare ($9.95)? Cheers, Jimmy

    Hey Jimmy. CloudFlare SSL won't replace our Hostinger's SSL, as it can't fully encrypt the connection. If you are using CloudFlare, your domain is connected to CloudFlare, and then the CloudFlare connects to your host (Hostinger). CloudFlare only has the authorization to encrypt the data between the domain and CloudFlare's servers. On the topic of CloudFlare via Hostinger, when you pay the CloudFlare protection via Hostinger, your CloudFlare will be integrated directly in your Hostinger dashboard. This makes it much easier to control, and you won't need to change the DNS at all.
