This service tests the validity of an RSS 2.0 feed, checking to see that it follows the rules of the RSS specification. For advice from the RSS Advisory Board on how to implement RSS and handle issues such as enclosures and HTML encoding, read the RSS Best Practices Profile. This checker is also a validator of Atom and RSS 1.0 feeds.

Use this tester regularly to ensure that your RSS feed continues to work well in the wide audience of RSS readers, podcast clients and other software that supports the format.
