Web syndication is a form of syndication in which a section of a website is made available for other sites to use. This could be simply by licensing the content so that other people can use it; however, in general, web syndication refers to making Web feeds available from a site in order to provide other people with a summary of the website's recently added content (for example, the latest news or forum posts).

Today many different types of content is syndicated on the Internet. Millions of online publishers including newspapers, commercial web sites and blogs now publish their latest news headlines, product offers or blog postings in standard format news feed.

Syndication benefits both the websites providing information and the websites displaying it. For the receiving site, content syndication is an effective way of adding greater depth and immediacy of information to its pages, making it more attractive to users.

This generates new traffic for the transmitting site — making syndication a free and easy form of advertisement.
