One of the ways to promote your website is by providing fresh content regularly and announcing it by the use of feeds. Feeds are a very useful way of distributing fresh content to your visitors and attracting their attention when new stuff is added. They consist of a file (or more) in which you put a summary of the latest content on your website, using a specific format (the most used are RSS and Atom), that allows you to add more information like icons, dates of addition, summaries, URLs, etc. All this information can be read by feed readers, which will alert their users when the content has been updated.
