The web syndication refers to the retransmission or redistribution of website content in which part of the web page information is made available to other websites.
This can be simply licensing the content so that other people can use it, but in general, web syndication refers to provide informative content from a web source originating from a website to provide other people updating the same (for example, a newspaper news, new articles on a blog, recent comments at a forum, etc.).
Usually this web syndication is done by contract or license between the parties: site of origin and destination website. Although “web syndication” is the correct term, those who use jargon most often use the term content syndication.
To read a web source you must subscribe through an aggregator, an application (desktop or web based) that shows the new contents published by web font provider signed.
This had its origin in the news pages and blogs, but whenever you use more to retransmit any information. The web syndication is also gaining importance in online trading, because Internet users are reluctant to provide personal information for commercial purposes (like joining a newsletter) and instead wait for the opportunity to receive information by subscribing to a source web syndication to allow its contents.
RSS Feed in practical terms

The website or reader receives a summary receiver (web feeds) for the latest information of the sending site. This feature allows Internet users consume in one place and summary form only content of interest to all web sites you visit.
