An XML feed is a form of Paid Inclusion or Search Engine Submission in which an XML document is used to provide a search engine with information about multiple web pages. An XML feed is particularly useful for multimedia sites or database sites that draw a variety of relevant search queries.
An XML feed is a data format that is used to store, process, or pass structured information between systems. On the one hand, there is a source of information that generates the content of the XML feed into a file with a suffix. xml, and on the other hand there is a system or even several systems processing data from the generated file.
