On average, a visitor needs almost six seconds to see if a certain resource seems useful or not. Displaying all the necessary content elements with the minimum time spent on page load is a task for the CDN — Content Delivery Network.In order to keep a user on the site and bring him to the target action, we use different optimization methods: eye-catching design, highly qualified and useful content, SEO optimization, etc. However, we quite often overlook details that end up playing a big role in how the site works, influencing its rankings and visits.The loading speed of the website affects its positions in the list of search results and influences user behavior, which is also important for rankings and conversion rates. Let's talk about the loading speed of page files and CDN, one of the effective ways to optimize the site. What is a CDN?Content Delivery Network is a system to increase the speed of loading files on the website. This is done through several servers located at great distances from each other.How CDN worksThe CDN acts as a bridge: it connects all servers to the same network and allows content to load faster. Sometimes it is possible to reduce user wait time by 5-6 seconds.What is a CDN used for?Of course, no one likes to wait. We don't like to stand in line, wait for a bus or wait C级执行名单 in line until we are connected with someone. Pretty much the same feeling as users staring at the screen for 10-15 seconds and expecting a miracle. However, according to statistics, even 7-10 waits is too much. As a result, people simply run out of patience, leave the site, and we lose potential buyers or readers.The longer the images, texts, files and other page elements, the less interested and patient users are. This is why content loading speed is the most influential factor that positively affects user behavior and overall site reputation.The important role is played by the distance between a server and the user. The longer it is, the longer it will take until all the data appears on the screen. The CDN makes it possible to use and connect several servers which are located as close as possible to the users. This reduces waiting time and helps to speed up page loading for all users, regardless of location.What sites need CDNs? Sites that contain many large files should definitely use the Content Delivery Network. The CDN greatly helps in reducing the loading time and prevents various data loading failures.In addition, for multilingual sites, the use of the CDN is strongly recommended. The content of these sites is generally translated into at least two languages. Therefore, the server must load at least twice as much information. The users of these sites are scattered all over the world and most of them are located quite far from the main server.Thanks to the CDN, we can create a whole chain of additional servers that are located as close as possible to each user, which allows for more sustainable and faster data delivery and makes the resource accessible to a greater number of users.CDN BenefitsOne of the biggest advantages of CND is that it positively influences rankings. Search engines track user actions and behavior on the site.As such, the site is considered useful or not to visitors. The faster the content loads, the less likely the user is to leave the resource. In addition, search engines themselves estimate the speed of the general site.In addition to increasing file loading speed, the Content Delivery Network also has other benefits:1Reduced server traffic. In the case of default hosting, the reception, processing and transmission of all data to each user are ensured by a single server. The CDN helps distribute this load healthily across multiple servers.
