RSS stands for Really Simple Syndication, a simple way to automatically be informed of updates in your online store, for example, when new products have been added. RSS feeds are also often used in blogs and news websites.
Customers may use their RSS reader (for example Google Reader) to stay abreast of the latest changes in your online store, without having to check the entire site for changes or what is new. Within the RSS reader interface, they may click on new products in your online store, if so desired.
To do so, customers will first have to “subscribe” to your online store through an RSS feed.
RSS feeds may be disabled through GENERAL > Settings > Hide RSS Feeds.
