What Is RSS

This tag gives a plain-language introduction to RSS, Really Simple Syndication, what it is, how it differs from a social media feed, and why it's still the backbone of most content automation tools today, PostRSS included. An RSS feed is a structured document a website generates automatically, listing recent updates in a format software can read reliably, which is exactly what PostRSS checks every 5 minutes to detect new content. This tag is a good entry point for readers unfamiliar with RSS before moving on to feed-setup or automation guides elsewhere on the blog. Understanding RSS at a basic level makes later, more technical articles about feed troubleshooting and formatting easier to follow. Readers already comfortable with RSS as a concept can skip ahead directly to the automation or platform-specific tags.
