RSS-Feeds

RSS or Really Simple Syndication is a family of web feed formats you can use to publish frequently updated information such as blog entries, news headlines, audio, and video in a standardized format to the subscribers of your RSS-feed.

An RSS document (which is called a "feed", "web feed", or "channel") includes full or summarized text, plus metadata such as publishing dates and authorship.

Web feeds benefit you as a publisher by letting you syndicate content automatically and they benefit readers who want to subscribe to timely updates from your website.

A standardized XML-file format allows the information to be published once and viewed by many different programs.

RSS-feeds can be read using software called "RSS-readers", "feed readers", or "aggregators", which can be web-based, desktop-based, or mobile-device-based. The user subscribes to a feed by entering into the reader the feed's uri or by clicking an RSS-icon in your website that initiates the subscription process.
The RSS-reader checks the user's subscribed feeds regularly for new information, downloads and updates that it finds, and provides a user interface to monitor and read the feeds.

RSS-feeds are an easy-to-maintain channel to keep in continuous contact with your subscribers/customers.
