RSS (or Really Simple Syndication) is a format that allows online publishers (like yourself) to share and distribute content from your website directly to the users computer via an RSS reader.
Why should I use RSS?
Enabling RSS Feeds on your website can increase website traffic by notifying site visitors to return to your website to view newly added content.
You can add the RSS icon to any dynamic list module where the 'Display RSS Link' tickbox is available in the module settings (i.e. Category List, Product List, Events List, etc). Site users can then subscribe to the related RSS feed. They will receive notification via an RSS reader when new content is added to that particular RSS Feed.
