How to Setup Cloudflare Free CDN in WordPress

Disclosure

If you have a website, then a CDN is one of the fastest ways to improve the load times of your WordPress website. Unfortunately, most companies only offer paid plans for their CDN services. But Cloudflare provides a free CDN plan along with a few key features. I will walk you through the steps to setup Cloudflare free CDN plan for your website.

What is a CDN?

CDN, or Content Delivery Network, is a distributed set of servers located worldwide that helps deliver content to your visitors from the server closest to their location.

If you are hosting your website on a server in the USA, then visitors from geographically distant locations like countries in Europe, Asia, the Middle East, or South America would see a delay or take longer for your website’s web pages to load for them.

The longer the distance, the more latency your visitors experience.

The companies providing CDN services set up “Edge servers” in locations worldwide. When you sign up for a CDN service, the static content of your website will be replicated worldwide to these edge servers.

With the CDN in place, a visitor to your site will not need to hit your server in the USA. Instead, the CDN will serve the web page to the visitor’s browser from the closest edge server. For example, if your visitor is from Japan, they will probably be getting the content delivered from an edge server in Hong Kong. This reduces the distance for the data to travel, thus reducing latency.

Deploying a CDN service is a recommended way to speed up a WordPress website and improve user experience.

What is Cloudflare CDN?

Cloudflare is the most popular CDN provider on the internet today. It is estimated that 20% of all websites use Cloudflare today. In addition, Cloudflare has an edge network that is one of the best, with 95% of the connected world within 50 ms of a Cloudflare server.

Cloudflare has a free plan, along with paid plans. The Cloudflare free plan is great for individuals and small businesses with a limited budget. The Cloudflare free plan offers the following features:

  • DNS Resolver services – use Cloudflare nameservers as your DNS service. Cloudflare DNS resolver is one of the fastest in the world and is highly recommended.
  • DDoS Protection – protects your website from DDoS attacks (Distributed Denial of Service)
  • CDN Services – replicates your content on edge servers worldwide and delivers fast load times to your users or visitors
  • SSL certificate (free) – secures data transfers between you and your website’s visitors—peace of mind for every website owner.

All the above services are offered free under the Cloudflare free plan. This is excellent value for money for anyone looking for the first level of protection and fast content delivery.

Steps to setup Cloudflare free CDN in WordPress

Let us start with signing up for the Cloudflare plan, then proceed to add your domain to Cloudflare, and finally, how to integrate it with your WordPress website.

Total Time: 10 minutes

    Cloudflare offers a choice of Pro, Business, Enterprise, and the Free plan. Select the “Free” plan from the list and click on “Continue”.

  6. Review DNS Entries

    Cloudflare will scan for existing DNS records for your domain name and list all the records it finds. You must review these DNS records and compare them with your existing records. If any entries are missed out, use the “Add record” feature to add the missing entry.

    Once you are happy and everything looks okay, click “Continue” to move to the next step.

  7. Update your Nameservers

    This is the final step of routing your domain via Cloudflare. You must log in to your domain registrar and change the nameservers. In our example, GoDaddy is the domain registrar. So we will need to log in to the Godaddy Account, browse to the DNS management section, and change the nameservers on GoDaddy to the new servers provided by Cloudflare.

    Depending on your registrar, it can take up to 24 hours for the change in nameservers to propagate worldwide.

    You can notify Cloudflare to verify the nameservers have been updated by using the “Check Nameservers” option.

  8. Configure Security and Performance Options

    With the DNS configuration settings done, the next step is configuring a few security and performance options to complete the process. Finally, click on the “Get Started” button.

  9. Set up Automatic HTTPS Rewrites

    The first step is to turn on automatic HTTPS rewrites. This converts all mixed content into https content, ensuring that all the content delivered to your website visitors is secure. Next, turn On the feature, and click the “Save” button.

  10. Turn On Always Use HTTPS

    Free Cloudflare Account for Website Always use HTTPS e1681146530323

    Turn On the Always Use HTTPS setting and click on the “Save” button. This ensures all traffic from your website is encrypted.

  11. Turn on Brotli Compression

    Free Cloudflare Account for Website Compression e1681146840303

    Brotli Compression is like GZIP compression. It compresses the files being transferred between your CDN server and the browser and makes it smaller. The smaller the file, the faster the transfer and load times for website users.
    Turn on Brotli compression, and click on the “Save” button.

    To learn more about compression, you can read this article on GZIP and WordPress compression. Brotli is an alternative to GZIP and operates on the same principle.

  12. Finish Cloudflare free CDN Setup for WordPress

    CDN or Content Delivery Network

    You have completed adding your domain, verified DNS entries, changed nameservers to Cloudflare, and set up security and performance options. The free Cloudflare CDN setup for WordPress is now complete and is ready to power your website. The website content will automatically cache on Cloudflare’s edge servers and serve it directly to your website visitors.

Advanced Settings for Cloudflare

With the basic Cloudflare for WordPress setup in place, your website will start to see the benefits of having a CDN. But there is much more that Cloudflare offers, and with a few additional settings, you can take advantage of them.

This doesn’t mean you should turn on every feature you can find. Some of them may not deliver what you expect or might conflict with existing settings or plugins on your website. Take these only as recommendations, and test the stability and performance of your website with any changes you make. If the website breaks, then revert the settings.

I will provide a quick rundown of the settings you can explore and the benefits they will provide.

SSL/TLS Setting

  • Browse to SSL/TLS > Edge Certificates and scroll to TLS 1.3 section and Enable
  • TLS 1.3 is the latest version of the encryption protocol used by HTTPS for communication. This version is faster and more secure.

Bot Fight Mode

  • Browse to Security > Bots, and ensure the Bot Fight Mode is disabled.
  • Bot fight mode is a great feature, but it inserts a javascript into your page, affecting load times. Turn this on only if you suspect your website has a bot issue.

Security Settings

  • Browse to Security > Settings, set the Security level to medium, and turn on Browser Integrity check and Privacy pass support.
  • These security settings protect your website. If the security level is higher than medium, Cloudflare will show a challenge page to your visitors, which may detract from a good user experience. So use it only if absolutely needed.

Speed Optimization

In addition to the CDN service, which delivers an immediate performance improvement for your website, Cloudflare also provides additional speed optimization features.

  • Turn on Early Hints under Optimized Delivery, but disable the rocket loader.
  • Early Hints tells browsers to preload linked assets faster for faster load times.
  • Rocket Loader is a feature that helps improve your pages’ paint time, but it has a known history of conflicts with other plugins. I have faced this issue on the Coolfundas blog, and it took me a while to figure out that this feature conflicted with the WP-Rocket cache plugin. You can try it out and see if it makes a difference, but ensure you do an in-depth test of your website before keeping it enabled long-term.

Cloudflare Caching Settings

Caching content on Cloudflare Edge servers delivers the primary CDN feature for your website.

  • Browse to Caching > Configuration: Set Caching level to Standard, Browse Cache TTL to 1 month, and enable Crawler hints and Always Online.
  • The Caching level and Cache TTL set the level of content cached and how long the browser caches files.
  • Crawler hints make search engine crawling more efficient, and Always Online serves pages of your website even if your server is down.

Cloudflare Page Rules for WordPress

Now that you have set up Cloudflare for WordPress, the next step is configuring some basic page rules for the CDN.

Page rules are a set of rules that lets you control how Cloudflare works on your website at a page or URL level. By setting page rules, you define the pages, conditions, triggers, and actions for when and how the CDN operates.

You can tell Cloudflare to exclude some pages from the CDN (bypass the CDN) or use the wildcard * to apply rules to all website pages or even a subset of pages.

The Cloudflare free CDN plan allows you to set “3” page rules. Let us look at a few key page rules that we can set up on the free plan.

Rule 1: Increase Security for Admin Pages and bypass cache

The administration page of any WordPress site is the gold mine for hackers and like. You want to make sure that this page has the highest protection. You also want to prevent the administration pages from being cached and ensure you see the latest pages.

Enter the URL as per the format below, and then set the security level to “High” and cache level to “Bypass” and disable apps and performance. Save the rule to activate.

Rule 2: Stop Caching Preview Pages

Preview pages are the draft view of your edits, so you want to make sure that these pages are not cached.

Enter the URL per the format below, and set the cache level to “Bypass” to stop the caching of preview pages.

yourdomain.com/*preview=true*

Rule 3: Forward XMLRPC URLs

XMLRPC is a popular target of brute force attacks. XMLRPC is an API that allows WordPress to communicate with external apps. If you were building a mobile app to communicate with WordPress, you would need it.

If you are not using it, you can disable XMLRPC. An alternative is to set a page rule to forward it to any URL like your home page.

To set a page rule, enter the XMLRPC URL as shown in the URL block below, select the “Forwarding URL” option with a 301 direct, and enter a destination URL like your home page.

yourdomain.com/xmlrpc.php*

There are a number of other page rules that can also be set:

  • Decrease bandwidth of WP Uploads
  • Keep important pages always online
  • Obfuscate email on the Contact page
  • Stop caching of eCommerce dynamic content using AJAX
  • Cache everything

You can decide which rules to set based on your need.

How to check if Cloudflare CDN is working?

You can check if Cloudflare is working in three ways:

  • Option 1 – Use the browser inspect tool
  • Option 2 – Use an HTTP Header checker tool
  • Option 3 – Use a CDN Performance tool

I will go through all the options in detail.

Option 1: Use the Browser Inspect tool

  • Open your WordPress website on the browser. You can open any URL on your website.
  • Right-click anywhere on the web page, and select the “Inspect” option
  • Select the network tab on this console. Make sure you set the filter for JS or CSS files
  • Select a JS or CSS file from the left nav bar, and view the header tab
  • Scroll to the Response Headers section, and look for the “cf-cache-status”
  • The cf-cache-status will have the value “HIT” if Cloudflare is working
  • If the cache status is MISS, the page is not coming from the cache. Refresh the page and check again.

Option 2: Use an HTTP Header checker tool

Use an HTTP header checker tool to view the response headers for a website page.

  • Go to the HTTP Header Checker tool.
  • Enter any URL for your website. It could be the home page or any post.
  • Click on the “Check” button to run the checker tool.
  • The header response will be displayed as shown in the image below.
  • Look for the cf-cache-status = HIT. Refresh the page once if it shows as a MISS.

Option 3: Use a CDN performance tool

The previous options explained will help you check the working of the CDN from a single location. But how do you check if the CDN is working correctly for users across different geographical locations? To verify this, you can use the free CDN performance tool from Uptrends.

The test will take a minute or two to complete. The tool will check your website from different locations in the Europe region and will provide you with a summary table of results from each location. You can change the last column from “Date” to “CF-cache-status” to see if the CDN is a HIT or a MISS from that location. You can also click on each location to see the full response headers if you are looking for a drill-down into the details.
