With the high popularity on the improvement of WordPress website speed and security, CDN is recognized as a good helper for site development. Have you ever wondered whether CDN is critical for your website? In this article, we explain carefully what is a CDN (content delivery network), how it works, and why you need it for WordPress sites to help clients who are confused with questions about CDN.
CDN, the short of Content Delivery Network, is a globally distributed system of servers which are placed at a variety of data centers across the Internet. It deliveries cached static contents of websites to visitors based on their locations. Is it still confused? Let’s explain it plainly.
Regularly, a visitor is redirected to the host’s web server (i.e BlueHost, locating its web server in Utah, US) to access your website content when she /he visits your WordPress site. If you have a large number of visitors, your website may be caught in slow page loading speed or even the server crash.
For example, your website is hosted on the server located in Utah, US, and someone from Shanghai, China visits it, then she / he can be redirected to the closest server that is probably located in HongKong. However, if someone from Manchester, England, she / he will be redirected to the closest server in London in some cases.
As a result, visitors can obtain the necessary content from the closest server, which improves the response speed of the user to access the site. In addition, visitors from different places access to the different server, so that CDN maximizes the bandwidth for visits and addresses the network congestions.
Why CDN is Important for WordPress Blog?
After learning about CDN, you can clearly understand that CDN has a big influence on your website performance. In below, we have explained the main highlights in detail that why you need CDN for your WordPress sites.
Speed Up Website
Once you start using a CDN on your website, your website data and files are cached and stored in all of the servers across of the Internet. So your visitors can get the content and data from the closest server from their locations, which greatly improve the access speed and page loading speed.
Speed improvement is one of the biggest benefits of using a CDN, especially for international websites which have many foreign visitors. Generally, people can visit the domestic servers quickly, but for distant, they access the foreign websites very slowly. However, if using a CDN on your website, they can access your content from their domestic servers, which greatly increase accessing speed.
As CDN distributes your content into various servers, visitors coming from different places will be redirected to different servers. So instead of bring 100% traffic to your main server which may lead to server overload or crash, CDN distributes the visiting pressure into a large number of servers, thus making your server more reliable and is less likely to go crash.
Improve User Experience
Research shows that a 1 second delay in page response can be a 7% reduction in conversions. The longer a visitor waits for your site to load, the less likely they are to buy the products or services. In addition, we have also seen the increasing of page views. So using CDN service, you can improve the user experience of your website.
Make for SEO
Google search engine has clearly claimed that the faster websites can be ranked higher in search results. We cannot guarantee that your website can get more traffic after using CDN. However, it definitely be ranked higher in search result page, which increases the possibility to drive more visitors.
