Best Practices for Setting Up Your Blog with Cloudflare Hosting

Cloudflare isn’t a hosting provider in the traditional sense (like Bluehost, SiteGround, or AWS EC2). It’s a Content Delivery Network (CDN) and security platform that sits in front of your existing web hosting. You still need a separate host for your blog’s files and database. This article focuses on best practices for leveraging Cloudflare’s features to enhance the performance, security, and reliability of your blog, regardless of your underlying hosting provider.

Understanding the Setup:

Before diving into best practices, let’s clarify the typical setup:

  1. Your Web Host: This is where your blog’s files (WordPress, static HTML, images, etc.) and database reside.
  2. Your Domain Registrar: This is where you registered your domain name (e.g., GoDaddy, Namecheap).
  3. Cloudflare: Acts as an intermediary between your visitors and your web host. It caches content, filters traffic, and provides security features.

The flow looks like this:

Visitor Request -> Cloudflare (DNS, CDN, Security) -> Your Web Host -> Response back through Cloudflare -> Visitor

Best Practices:

Here’s a detailed guide to setting up and optimizing your blog with Cloudflare:

1. DNS and Nameserver Configuration:

  • Change Nameservers (Critical): After signing up for Cloudflare, you’ll be given Cloudflare’s nameservers. You must update these at your domain registrar. This is the fundamental step that directs traffic through Cloudflare. Failure to do this means Cloudflare won’t be able to do anything. Find your registrar’s instructions for changing nameservers; they’re usually readily available.
  • Add Your Domain to Cloudflare: Follow the on-screen instructions in the Cloudflare dashboard to add your domain. Cloudflare will usually auto-detect most of your existing DNS records.
  • Verify DNS Records: Carefully review the DNS records Cloudflare imports. Make sure all necessary records (A, CNAME, MX, TXT, etc.) are present and correctly configured. Common mistakes include missing subdomains or incorrect mail server (MX) records.
    • A Records: Point your domain (e.g., example.com) and www subdomain (e.g., www.example.com) to your web host’s IP address. Ensure these are “Proxied” (orange cloud icon) in Cloudflare. This means traffic goes through Cloudflare.
    • CNAME Records: Often used for subdomains (e.g., blog.example.com). If you have subdomains pointing to other services (e.g., a separate email provider), make sure those CNAME records are correct. Often, these are also proxied.
    • MX Records: Essential for email. Ensure these point to your email provider’s servers, not your web host (unless your web host also handles your email). These are typically not proxied.
    • TXT Records: Used for various purposes, including domain verification (e.g., for Google Search Console) and email authentication (SPF, DKIM, DMARC). Ensure these are correctly copied.
  • Understand Proxy Status (Orange Cloud vs. Gray Cloud):
    • Orange Cloud (Proxied): Traffic goes through Cloudflare. You get CDN, security, and performance benefits. Use this for your website (A and CNAME records typically).
    • Gray Cloud (DNS Only): Traffic goes directly to your origin server. Cloudflare only provides DNS resolution. Use this for services that shouldn’t be proxied (e.g., MX records, direct FTP access).
  • Disable your previous DNS host’s services. Once your name servers have been switched over to Cloudflare, you need to disable the services provided by your previous DNS host.

2. SSL/TLS Encryption:

  • Enable “Full (Strict)” SSL: This is the most secure option. It requires a valid SSL certificate on your origin server (your web host). Many hosts provide free Let’s Encrypt certificates; use one. “Full (Strict)” ensures encrypted communication between the visitor and Cloudflare and between Cloudflare and your origin server.
    • “Flexible” SSL: Encrypts traffic between the visitor and Cloudflare, but not between Cloudflare and your origin. This is less secure and not recommended if you can get a certificate on your origin server.
    • “Full” SSL: Encrypts both legs, but doesn’t strictly validate the origin certificate. Less secure than “Full (Strict)”.
    • “Off”: Do not use this. All traffic will be unencrypted.
  • Enable “Always Use HTTPS”: This redirects all HTTP requests to HTTPS, ensuring visitors always use the secure connection. Find this in the “SSL/TLS” -> “Edge Certificates” section.
  • Enable “Automatic HTTPS Rewrites”: This helps fix mixed content issues (where some resources on your HTTPS page are loaded over HTTP). Also found in “Edge Certificates.”
  • Enable HSTS (HTTP Strict Transport Security): This tells browsers to always use HTTPS for your domain, even if the user types http://. This adds an extra layer of security. Configure this with a “Max-Age” (e.g., 6 months or 1 year). Start with a shorter duration and increase it once you’re confident everything is working correctly. Found in “Edge Certificates.”

3. Caching Configuration:

  • Caching Level: Set this to “Standard.” This caches static content (images, CSS, JavaScript) based on standard HTTP headers.
  • Browser Cache TTL: Set this to a reasonable value (e.g., “Respect Existing Headers” is a good default). This tells browsers how long to cache resources locally. If you have resources that change frequently, you might use a shorter TTL.
  • Cache Everything (Page Rule – Advanced): For truly static pages (e.g., “About Us,” “Contact”), you can create a Page Rule to “Cache Everything.” This caches the entire HTML page, significantly improving performance. Be very careful with this, as it can cache dynamic content (e.g., logged-in user areas) if not configured correctly.
    • Example Page Rule:
      • URL: example.com/about* (matches /about and any sub-paths)
      • Setting: Cache Level: Cache Everything
      • Setting: Edge Cache TTL: (Set a reasonable time, e.g., 1 day)
  • Bypass Cache on Cookie (Page Rule – Advanced): If you have dynamic content (e.g., a WordPress admin area, user login pages), you must create Page Rules to bypass caching for those areas. The most common way to do this is to bypass caching based on cookies.
    • Example Page Rule (WordPress Admin):
      • URL: example.com/wp-admin*
      • Setting: Cache Level: Bypass
    • Example Page Rule (Logged-in Users – WordPress):
      • URL: example.com/* (matches everything)
      • Setting: Cache Level: Bypass
      • Setting: If the URL contains a cookie named "wordpress_logged_in" (This is the standard WordPress logged-in cookie. Other platforms will have different cookie names).
  • Development Mode: When making changes to your site, temporarily enable “Development Mode” in Cloudflare. This bypasses the cache, ensuring you see the latest version of your files. Remember to turn it off when you’re done.

4. Security Settings:

  • Web Application Firewall (WAF): Enable the Cloudflare WAF (available on paid plans). This protects against common web attacks (SQL injection, cross-site scripting, etc.).
  • Security Level: Start with “Medium” and adjust based on your needs. Higher security levels might block legitimate traffic, so monitor your logs.
  • Bot Fight Mode: Enable this to challenge or block automated bots, reducing malicious traffic.
  • Rate Limiting (Paid Plans): This protects against brute-force attacks and excessive requests. Configure rules to limit the number of requests from a single IP address within a specific timeframe.
  • IP Access Rules: If you have specific IP addresses that need access (e.g., your development team) or need to be blocked (e.g., known malicious IPs), you can configure IP Access Rules.
  • Page Rules for Security: You can use Page Rules to apply specific security settings to certain parts of your site. For example, you might increase the security level for your login page.

5. Performance Optimization:

  • Auto Minify: Enable minification for HTML, CSS, and JavaScript. This removes unnecessary characters from your code, reducing file size and improving load times.
  • Brotli Compression: Enable Brotli compression. This is a modern compression algorithm that often outperforms Gzip, further reducing file sizes.
  • Rocket Loader (Optional – Test Carefully): Rocket Loader attempts to improve JavaScript loading performance. However, it can sometimes cause issues with certain scripts. Test it thoroughly before enabling it permanently. If you experience problems, disable it.
  • Image Optimization (Paid Plans – Mirage, Polish): Cloudflare offers image optimization features (Mirage and Polish) on paid plans. These can automatically resize, compress, and convert images to WebP format, significantly improving image load times.

6. Monitoring and Troubleshooting:

  • Cloudflare Analytics: Use Cloudflare’s analytics to monitor traffic, performance, and security events.
  • Cloudflare Logs (Paid Plans): If you have a paid plan, Cloudflare Logs provide detailed information about requests and responses, which can be helpful for troubleshooting.
  • Check Your Origin Server’s Logs: If you’re experiencing issues, also check your web host’s server logs (e.g., error logs, access logs).
  • Test Thoroughly: After making any changes, thoroughly test your website to ensure everything is working as expected. Use different browsers and devices.

7. Specific Considerations for WordPress:

  • Cloudflare WordPress Plugin: While not strictly necessary, the official Cloudflare plugin can simplify some configurations (e.g., automatically purging the cache when you update content).
  • Caching Plugins (Careful Consideration): If you’re using a caching plugin in WordPress (e.g., W3 Total Cache, WP Super Cache), you need to configure it carefully to avoid conflicts with Cloudflare’s caching. Generally, you should disable page caching in your WordPress plugin and let Cloudflare handle that. You can still use the WordPress plugin for other features (e.g., database optimization, object caching).
  • Disable XML-RPC: If your blog is getting hit with XML-RPC attacks, you can disable it in your .htaccess file or via a security plugin.
  • Use a security plugin. Use a plugin such as Wordfence or Sucuri Security for additional security features.

Conclusion:

By following these best practices, you can leverage Cloudflare to create a faster, more secure, and more reliable blog. Remember that Cloudflare is a powerful tool, but it requires careful configuration. Test thoroughly, monitor your site’s performance, and adjust your settings as needed. The combination of a good web host and a properly configured Cloudflare setup will provide an excellent experience for your visitors.
