WordPress CDN: Enhance Performance and Security Instantly

Website visitors expect lightning-fast websites. Research shows how speed remains crucial to your bottom line – for e-commerce sites, a 1-second load time results in an average conversion rate of 3.05%. Stretch that delay to 4 seconds and conversions plummet to just 0.67%. To put this in perspective, a site selling $50 products could lose over $1,190 in revenue for every 1,000 visitors simply because of slower load times.

However, integrating a content delivery network (CDN) with your WordPress site can dramatically improve your site's performance and security. In this guide, we'll compare the top providers and show you exactly how to set up and optimize your CDN for maximum performance.

TL;DR: A CDN distributes your site's content across global servers, delivering faster load times and better security. While there are several CDN options available, Pantheon's Global CDN stands out by offering an all-in-one solution that's pre-configured and optimized specifically for WordPress sites.

WordPress CDNs: Boosting Speed and Security for Your Site

A CDN transforms your WordPress site’s performance and security by distributing its content across a global network of servers. This means that when someone visits your site, they access it from a server geographically closest to them. The result? Drastically reduced load times and a far smoother user experience, regardless of where your audience is located.

Faster load times are also a key ingredient for success online. Search engines like Google prioritize fast-loading sites, rewarding them with higher rankings. Plus, with quicker pages, your bounce rates plummet and visitor engagement skyrockets, creating a virtuous cycle of improved user satisfaction and business results.

But speed is only part of the equation. CDNs also deliver a hardy layer of security to your WordPress site. Features like DDoS protection, which defends against malicious traffic and provides secure data transfer, ensure your site stays online and your visitors’ data remains safe. For organizations handling sensitive information or catering to a global audience, this level of security is beneficial and important.

Take PEN America, for example. By using modern WordPress solutions, they amplified their mission of advocating for free expression and also fortified their site’s defenses against potential threats. Their ability to combine powerful performance with resilience is a testament to the value of integrating a CDN.

How To Set Up a CDN for WordPress: Step-By-Step Guide

Setting up a CDN for your WordPress site is one of the most effective ways to improve its performance and security. Here’s a step-by-step guide to get you started:

 1. Select a CDN provider

Choose a CDN provider that aligns with your site’s needs. Refer to our detailed comparison of the top 5 providers!

For easy integration and powerful features, we highly recommend Pantheon’s Global CDN.

2. Back up your WordPress site

Before making any changes, back up your WordPress site to avoid data loss. Use reliable plugins like UpdraftPlus or BackupBuddy to create a full site backup, including your database and files.

3. Sign up for a CDN service

Register on your chosen CDN provider’s website. Enter your website’s URL in the CDN dashboard. Follow any prompts to complete the initial setup.

Note: If you’re using Pantheon, our Global CDN is enabled by default for all sites on our platform, so you can go ahead and skip straight to step 6. 

4. Install a CDN plugin (if required)

For CDNs that require WordPress plugins, log into your WordPress dashboard and navigate to Plugins > Add New. Search for your CDN provider’s plugin, click Install Now, then Activate.

5. Configure CDN settings in WordPress

Your CDN provider will provide a CDN URL or CNAME, which routes your site’s static content through the CDN. Go to the CDN plugin’s settings in your WordPress dashboard and enter the CDN URL or CNAME. Select the types of content (e.g., images, CSS, JavaScript) to deliver via the CDN and save your changes.

6. Update DNS settings (if necessary)

For some CDNs, you’ll need to update your DNS records, so log in to your domain registrar. Locate the section for editing DNS records and point your domain to the CDN’s URL as instructed. On Pantheon, these instructions appear within our dashboard:

Note: DNS updates may take a few hours to propagate globally.

7. Enable HTTPS (SSL certificate)

Make sure your site runs securely over HTTPS by installing an SSL certificate. Update WordPress settings to redirect all traffic to HTTPS. 

By the way, Pantheon simplifies this process by automatically providing free HTTPS certificates via Let's Encrypt once your domain is added and DNS is configured.

8. Test your website

Here’s what you need to do:

• Clear caches: Purge caches in your WordPress and CDN dashboards.
• Check functionality: Browse your site to ensure all elements load correctly.

Run speed tests: Use tools like GTmetrix or Google PageSpeed Insights to confirm performance improvements.

Best Practices for Optimizing Performance

Enhancing your WordPress site’s performance goes beyond simply enabling a CDN. Here are some best practices to ensure you get the most out of your setup:

Caching

Enable both server-side caching and browser caching to reduce server load and speed up content delivery. Use Pantheon’s caching layers, including Redis, for optimized performance.

Performance Monitoring

Use New Relic APM, included with Pantheon, to monitor and debug performance issues.

When we were launching, we ran into performance bottlenecks with the suite of old WordPress plugins... New Relic on Pantheon helped debug a boatload of them.” 

– Paul Sheldrake, Engineering Manager at Kanopi Studios

Development Tools

• Use Multidev environments to test changes without affecting your live site. 
• Schedule automated backups through Pantheon’s dashboard for easy restoration.
• Implement version control with Git to manage code changes effectively.

Optimize Images and Files

• Compress images using tools or plugins like Imagify or Smush. Consider switching to WebP for better compression without sacrificing quality.
• Enable GZIP compression on your server to minimize file sizes sent to users’ browsers.
• Implement lazy loading to delay the image and video loading until users scroll down, reducing initial load times.

Lightweight Themes and Plugins

Choose WordPress themes designed for speed and avoid those with unnecessary features. Also, regularly update WordPress core, themes and plugins to benefit from performance and security improvements.

Database Optimization

Clean up your database using plugins like WP-Optimize to remove spam comments, post revisions and unnecessary data. You can use Pantheon’s Autopilot to keep plugins and themes updated automatically while ensuring compatibility.
