RSS is a standard format that publishes a website’s newest content as a structured feed. Instead of visiting a site to check for updates, a reader app or automation tool pulls the feed and tells you the moment something new appears. The letters stand for Really Simple Syndication, and simple is the point.
Think of it like a magazine subscription that arrives without you asking. You sign up once, and every new issue lands in your mailbox automatically. An RSS feed works the same way for a blog or news site: you add its feed URL to a reader, and new articles flow in on their own, no algorithm deciding what you see. Behind the scenes the feed is just a tidy XML file, similar in spirit to a JSON API but read-only and built for content updates rather than queries. Open one in a browser and you will see a list of items, each with a title, a link, a date and a short summary.
It quietly powers more than blogs. Every podcast on earth is distributed through RSS, and marketers use feeds to push fresh posts into newsletters and automation flows. Most platforms generate the feed for you, so a content management system often produces one out of the box. Readers like Feedly and NetNewsWire still have loyal users who want a calm, chronological view instead of a sorted timeline. And because the format is plain and open, a tool like Zapier or n8n can watch a feed and fire off an action the second a new item appears.
At TopDevs we include clean RSS feeds on the content sites we build, so a client’s posts can flow into newsletters, readers and automation without any manual copy-paste.
