Content Delivery Network
Many online services use a content distribution network (CDN) to deliver photos and other files as fast as possible. This improves site speed, which is a metric used by Google and other search engines as a ranking factor for search results.
CDN distribution works by keeping copies of commonly used photos and files simultaneously hosted at several data centers (nodes) around the world. Those photos and files are delivered by the node closest to the shopper, decreasing the distance they have to travel, thus making the site load faster. In this way, your store loads just as fast in Asia as it does in North America, improving the storefront shopping experience.
Currently, BigCommerce has CDN nodes in London, Los Angeles, New York, Sydney, Tokyo, Sao Paulo, Hong Kong, and Singapore.
We recommend taking advantage of the BigCommerce CDN if you want to customize your store's design. Refer to our developer documentation if you are using a Stencil theme, or Referencing Assets in a Theme for the proper format and syntax for Blueprint themes.
