Read the content of the website output by RSS format without opening the website page. This is the aggregate information experience that Rss brings to the user. RSS and Atom, as a kind of information aggregation technology, are used to share content (also called aggregated content) between sites. RSS uses XML as a standard way to share content with each other. It stands for Really Simple Syndication (or RDF Site Summary). RSS and Atom information aggregation technologies are supported by big-name companies such as Useland, Yahoo, Google, etc. It is more efficient to publish and share information, and to share more of the latest Internet information.
