RSS (Really Simple Syndication) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it — a structured, machine-readable file that lists a site’s latest posts, updated automatically every time something new is published.
RSS solves a problem for people who regularly use the web. It allows you to easily stay informed by retrieving the latest content from the sites you are interested in. You save time by not needing to visit each site individually. You ensure your privacy, by not needing to join each site’s email newsletter. The number of sites offering RSS feeds remains large today, spanning news publishers, blogs, podcasts, and e-commerce platforms alike — and virtually every modern CMS (WordPress, Shopify, Ghost, Substack) generates one automatically without any setup.
Feed Reader or News Aggregator software lets you grab the RSS feeds from various sites and display them for you to read in one place, instead of checking each site individually.
Popular, actively maintained feed readers in 2026 include:
Once you have your Feed Reader, it is a matter of finding sites that syndicate content and adding their RSS feed to the list of feeds your Feed Reader checks. Many sites display a small icon or link labeled RSS, or simply publish their feed at a predictable address like yoursite.com/feed/, to let you know a feed is available.
While RSS started as a way for people to read updates in a feed reader, the same underlying format is now widely used by automation tools to trigger actions the moment new content is published — without a person checking anything manually. PostRSS is one example: instead of a person subscribing to a feed in a reader, PostRSS subscribes to your feed on your behalf and automatically posts each new item to your connected social media accounts (Facebook, X, LinkedIn, Pinterest, VKontakte) the moment it appears. The feed format hasn’t changed since it was standardized in 2003 — what’s changed is how many different tools now read it.
RSS remains the standard, stable format behind podcast distribution, many news readers, and a large share of content automation tools — including social media auto-posting. Its simplicity is exactly why it hasn’t needed replacing: a title, link, and description per item is still all most automation needs.
An RSS feed is controlled entirely by the publisher and pulled directly from their own site, with no platform algorithm deciding what you see or when. Following on social media routes updates through that platform’s feed ranking, which may delay or hide posts depending on engagement signals.
No. Most sites publish a feed automatically, and a free feed reader like Feedly or Inoreader lets you subscribe with just the site’s web address — no coding or configuration required.
Yes — the same feed that a reader like Feedly subscribes to can be connected to an automation tool like PostRSS to auto-post new content to social media, or to other services that watch feeds for changes.
