Using a Content Distribution Network, also known as a CDN, can help you significantly reduce page load times<\/strong> for your website. They also often contribute to load balancing, bad bot mitigation, increased reliability, and more.<\/p>\n\n\n\n

With free CDN solutions available, there is little reason not to use one to improve your website performance. Today we\u2019ll be sharing more about these handy services you can use to ramp up your site speed and reliability.<\/p>\n\n\n\n

What is a CDN?<\/strong><\/h2>\n\n\n\n

CDNs are networks that help websites reduce latency during page load<\/strong>. When a web browser sends a request to your website, that request needs to travel a physical distance from the browser\u2019s location to where your hosting server resides.<\/p>\n\n\n\n

Latency is the time taken for data to traverse the distance<\/strong> between browser to web server and back. The further the distance – the higher the latency. <\/p>\n\n\n\n

For instance, a request made from a browser in New York<\/strong> to a server in Dallas <\/strong>will typically have a much shorter latency period than making a request from New York to Singapore<\/strong>.<\/p>\n\n\n\n

How Does a CDN Work?<\/strong><\/h2>\n\n\n\n

CDNs work by caching some of your website content in multiple server locations<\/strong>. For example, your web server may be in Texas, but the CDN could be caching parts of it in Europe, Asia, Australia, and all across the world.<\/p>\n\n\n\n

When a visitor makes a request intended for your website, the request will first go to the CDN. As the content delivery network receives these requests, two things will happen. <\/p>\n\n\n\n

First, the CDN starts serving cached data from the server <\/strong>closest to where the request originated. Simultaneously, the CDN passes the request to your web server<\/strong>, which loads all other elements.<\/p>\n\n\n\n

How Can a CDN Help Your Website?<\/strong><\/h2>\n\n\n\n

When used effectively, content delivery networks help websites in many ways. CDN solutions bring many advantages to the table and come at different price rates that cover projects of any size.<\/p>\n\n\n\n
