RSS (Really Simple Syndication) allows users to subscribe to frequent updates from their favorite websites through a personalized news feed. By subscribing to RSS feeds from various sites, users can stay up to date with all the latest information in one place. RSS feeds are typically indicated by an icon and are delivered to the user via an RSS feed reader, which compiles feeds from all over the web into a single list. Using RSS in public relations saves time, provides an alternative communication channel, and helps expand audiences through content syndication.
