How CDN works
A Content Delivery Network (CDN) works by bridging the physical gap between a website’s server and its visitors. When you access a site, your request doesn’t have to travel all the way to the main server; instead, the CDN’s intelligent network redirects it to a nearby edge server.
This server, also known as a Point of Presence (PoP), holds a cached copy of the website’s content. By serving content from the closest location, a CDN dramatically improves website performance and website speed, leading to a better user experience and higher search engine rankings.
What is Cloudflare?
Cloudflare is a global content delivery network (CDN) and DNS provider. It sits between your website and visitors, caching content worldwide to speed up load times, block malicious traffic, and provide uptime resilience.
As illustrated in the diagram, a Cloudflare CDN improves website loading speed and user experience by routing traffic to the nearest edge server. This process, known as latency reduction, ensures visitors are served content from a server close to their location, which drastically cuts down on loading times. By leveraging Cloudflare’s global network, your site can deliver a faster, more reliable experience to users worldwide.
- CDN Explained: Your site’s assets are served from servers closest to users, reducing latency.
- Free vs Paid: The free plan is enough for most personal, small business, and affiliate sites. Pro plans add features, but the basics—including CDN, DDoS protection, and SSL—are robust.
Step 1: Creating a Cloudflare Account
Creating a Cloudflare account is the first step toward optimizing your website. To get started, simply register with your Gmail account or any preferred email address. After entering your details, you will receive a verification link in your inbox. Click the link to verify your email and activate your account. Once verified, you can log in to your Cloudflare dashboard, where you’ll be able to add and manage your website’s settings to improve its performance and security.
- Go to Cloudflare Signup and create a free account.
- Verify your email and log in to the dashboard.
Step 2: Adding Your Domain
Once you’ve logged in to your Cloudflare dashboard, the next step is to add your website domain. This process is straightforward and typically starts with a prompt to add a new site. Simply enter the full domain name of your website (e.g., techfin2k.com) into the provided field and click ‘Add Site’. Cloudflare will then automatically scan your existing DNS records to prepare for the setup (Select the option- Quick scan for DNS records). This is the crucial step that connects your domain to Cloudflare’s powerful network, enabling it to handle your site’s traffic and provide its performance and security benefits.
- Click “Add Site” in the Cloudflare dashboard.
- Enter your domain (e.g., techfin2k.com).
- Choose the Free Plan during setup.
Step 3: DNS Records Review
- Cloudflare will auto-scan your domain’s DNS records.
- Review all records (A, CNAME, MX).
- Orange cloud: “Proxied through Cloudflare.”
- Grey cloud: “DNS only.”
Tips:
Always keep essential records (like mail) on DNS only—email hosting might break if proxied.
Step 4: Nameserver Configuration
After Cloudflare has scanned your domain’s DNS records, the final and most crucial step is to update your nameservers. Cloudflare provides you with two unique nameservers (for example, aria.ns.cloudflare.com and gabe.ns.cloudflare.com). These nameservers act as the new address book for your domain, directing all your website’s traffic through the Cloudflare network.
To complete this step, you will need to log in to your domain registrar (e.g., GoDaddy, Namecheap, Hostinger) where you originally purchased your domain. Locate the DNS management or nameserver settings page. Here, you will replace your registrar’s default nameservers with the two provided by Cloudflare.
This change signals to the internet that your domain’s DNS records are now managed by Cloudflare. It may take up to 48 hours for these changes to fully propagate across the internet, though it often happens much faster. You can check the status in your Cloudflare dashboard; once the configuration is successful, it will show a confirmation message.
- Cloudflare provides two nameservers (e.g., aria.ns.cloudflare.com, gabe.ns.cloudflare.com).
- Open your domain registrar and replace existing nameservers with those shown by Cloudflare.
- Example with Hostinger, GoDaddy, or Namecheap
- It may take up to 48 hours for propagation (Generally it takes less than in one hour). Check Cloudflare for success confirmation.
Step 5: A Record Configuration
To complete the setup, you need to configure your A records in Cloudflare. The A record links your domain name to your server’s IP address.
First, log in to your hosting provider’s dashboard (e.g. Hostinger) and locate the IP address of your website. This is typically found in the hosting details or DNS zone editor section. Copy this IP address.
Next, go to your Cloudflare dashboard and navigate to the DNS settings. Here, you’ll create a new A record. In the ‘Name’ field, you’ll enter ‘@’ to represent your root domain. In the ‘IPv4 address’ field, paste the IP address you copied from Hosting provider. This ensures that Cloudflare directs all traffic for your main domain to the correct server. You can also create A records for subdomains (e.g., ‘www’) by entering the subdomain name in the ‘Name’ field.
- In Cloudflare dashboard, navigate to DNS > Records.
- To point your domain to your hosting’s IP address:
- Set the “A” record: Name =
@, Content = Your host IP - Set www as CNAME pointing to root
@or add separate A record.
- Set the “A” record: Name =
Step 6: Performance Optimization
Cloudflare offers a range of performance-enhancing features to supercharge your website’s speed. To access these settings, navigate to the Speed and Optimization sections of your Cloudflare dashboard.
Here are the key settings to enable:
- Auto Minify: Turn on Auto Minify for HTML, CSS, and JavaScript. This feature removes unnecessary characters like comments and white spaces from your code, reducing file sizes without affecting functionality.
- Speed Brain & Early Hints: To take advantage of Cloudflare’s smart optimization, turn on Speed Brain and Early Hints. Speed Brain uses AI to automatically apply various performance tweaks, while Early Hints tells a user’s browser about important resources before the main page has even loaded, significantly reducing the time it takes for your site to become interactive.
- HTTP/2 and HTTP/3: Ensure that HTTP/2 and HTTP/3 are enabled. These are the latest versions of the web protocol and allow for faster, more efficient data transfer between the server and the user.
- Caching Level: Under the Caching tab, set your caching level to “Standard” for most websites. This ensures that static content is cached and served quickly to your users.
- Always Online: For added reliability, consider enabling the Always Online feature. This serves a cached version of your site to visitors even if your origin server is temporarily offline, ensuring your content is always accessible.
Step 7: SSL/TLS Setup
Once your domain is successfully connected to Cloudflare, the next vital step is to configure your SSL/TLS settings to secure your website. Navigate to the SSL/TLS menu in your Cloudflare dashboard.
For the best security, we recommend choosing either Full or Full (strict) mode. This ensures that traffic is encrypted not only between your visitors and Cloudflare but also between the Cloudflare network and your origin server.
To complete your security setup, enable these two crucial features:
- Automatic HTTPS Rewrites: This feature automatically changes insecure “http” links on your website to “https,” ensuring a fully encrypted connection and preventing mixed-content warnings.
- Always Use HTTPS: This feature automatically redirects all your visitors from the insecure “http” version of your site to the secure “https” version, guaranteeing every connection is encrypted.
Step 8: Caching Configuration
To maximize your website’s performance, it’s essential to configure Cloudflare’s caching settings to your advantage. Navigate to the Caching section in your dashboard.
- Browser Cache TTL: Adjusting the Browser Cache TTL (Time To Live) setting is a simple yet powerful way to speed up your site for returning visitors. By setting it to a longer duration, such as 1 month, you instruct visitors’ browsers to store a copy of your static files for a longer period. This means that when a user returns to your site, their browser can load assets like images, CSS, and JavaScript instantly from their local cache without needing to re-download them from your server.
- Page Rules: For more granular control, use Page Rules to create custom caching instructions for specific URLs or sections of your site. This is particularly useful for optimizing static content. For example, you can create a rule for yourwebsite.com/wp-content/uploads/* to set a higher caching level for all your image files, ensuring they are served directly from the CDN with maximum efficiency.
Troubleshooting Common Issues
Even with a smooth setup, you might encounter a few common issues. Here are some solutions to help you troubleshoot and ensure your site runs flawlessly on Cloudflare:
- Propagation Delays: While a full DNS propagation can take up to 48 hours, it’s important to note that changes often take effect in less than an hour. If you’re experiencing delays, simply be patient. You can use an online DNS checker to monitor the progress of your nameserver update.
- SSL Errors: If visitors see an SSL error, double-check your Cloudflare settings. The most common fix is to switch your SSL/TLS encryption mode to ‘Full’ or ‘Full (strict)’. This ensures traffic is encrypted all the way to your origin server, which must have its own valid SSL certificate.
- Email Issues: If your email service stops working after the nameserver change, it’s likely a DNS record issue. Make sure that you do not proxy your MX (Mail Exchange) or any other mail-related records through Cloudflare’s network. These records should have their orange cloud icon turned off, allowing them to bypass Cloudflare’s proxy.
- Mixed Content: If your site is showing a “Not Secure” warning despite having SSL enabled, it’s a mixed content error. This occurs when your secure HTTPS page is trying to load insecure HTTP assets (like images, SVGs, or CSS files). The easiest way to fix this is by enabling Automatic HTTPS Rewrites in Cloudflare, which automatically changes the insecure URLs to their secure HTTPS versions.
A Note on Performance Metrics
Since we do not have the initial performance test results, we cannot provide a direct “before and after” comparison. However, the optimizations enabled through Cloudflare are well-known to significantly improve core web vitals. The setup we’ve completed generally leads to a notable reduction in First Contentful Paint (FCP), Largest Contentful Paint (LCP), and overall Speed Index, resulting in a much faster and more responsive website for all visitors.
