RSS, short for Really Simple Syndication, is a web feed format used to publish frequently updated content such as blog entries, news headlines, audio, and video in a standardized format. An RSS document, called a "feed," allows users to access updates to online content in a standardized, computer-readable format. These feeds can be read using RSS reader apps or integrated into websites. In digital marketing, RSS feeds are valuable for distributing content automatically, enhancing content accessibility, and keeping audiences engaged with regular updates.
