Website speed is an ever increasingly important search engine ranking factor. Other than that it is also a factor that affects conversions on your website. A slow website can easily affect the user experience and result in high bounce rate. When building a new website you need to ensure it loads fast. This can be achieved in WordPress by using a high quality theme along with a cache plugin and a content delivery network. CloudFlare is the most popular CDN (Content Delivery Network).

What is a Content Delivery Network?

A CDN is a network of servers located around the world that deliver cached copies of websites from locations that are closest to the user. As the servers are closer to the user and the website copies are cached, websites load faster as a result.

CDNs such as CloudFlare also help prevent against DDOS attacks. This is done by forcing suspicious visitors to enter a manual captcha before accessing the website. Thereby eliminating bots. This also means your server resources are not wasted on bots.

The free plan offered by CloudFlare is the main reason it is the most popular CDN. It is perfect for beginners and small website owners.

To set up CloudFlare with WordPress you can use the official CloudFlare plugin.

For your websites URL enforce the https option. For your login url usually set the security level to high. For your admin area i.e. set the security level to high, bypass the cache and disable performance and apps. Here is an example of the page rules we have set up.

Other CloudFlare Settings

Under Attack Mode

If your website is under a DDoS attack you can make every visitor view an interstitial page as their traffic is analyzed before allowing them access to the website. This can be enabled on the settings home page.

Security Level

The security level can be set from “Essentially off” to “Under Attack” This determines when to display a captcha to website visitors. If your website visitors are complaining about this you can reduce the security level as CloudFlare can sometimes be over aggressive with the captchas.

Always online

If you enable this option, your visitors will see a cached copy of the site even if your website’s server is offline.

Development Mode

Since CloudFlare serves cached copies of your website, if you are making design changes you might not be able to see them. This option comes in handy in such situations and helps you to see changes to your website in real time.


There are many other settings you can configure on CloudFlare. Depending on your goals these will vary between various users. We have gone through the most important ones that you need to configure in order to get started with CloudFlare.

The basic plan is great for small website owners. If you have a larger website with high traffic you should definitely consider the paid plans. It is a great option for increasing the speed of your website alongside the security as well.
