The answer is: site goal.
Standards take an important place in providing reliable and high-quality information to the public, and defining the purpose of the information is one of the main criteria by which information sources on the Internet are evaluated. When this purpose is clearly defined, it helps provide a reliable basis for people to share the same expectations about a product or service. This facilitates the trade process and provides a practical framework that helps in achieving economies. When decisions are made based on these criteria, the required level of quality is determined and ensured that it is achieved accurately and effectively.
