A web feed or an XML feed is a online file which alerts the user about the frequently updated contents in your blog. It gets automatically updated when you update your blog’s content. An XML feed contains the title and description of latest articles and their links pointing to the original blog’s article. As you already know there are two types of feeds 1. Atom Feed and 2. RSS feed. Both these feeds are different slightly in their structure.
