7 Free Online Feeds Validation Tools


In this article I’m going to share 7 Great Online Feeds Validation Tools, which will be really useful to identify and fix invalid feeds.

Why You Should Validate Feeds?

From W3C, Validators help you to codify the specification (literally, to translate it into code) to make it easier to know when you’re producing RSS correctly, and to help you fix it when you’re not.

Many feed readers (including Google’s FeedBurner service) will not accept invalid blog/site feeds. So it is better to validate your site’s feeds first.

I mentioned 7 free feeds validation tools here and, to my knowledge, they are genuine!


This is a validator for syndicated feeds. It works with RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0, 1.1, and 2.0. It also validates Atom feeds. To use it, simply enter the address of your feed and click Validate. If the validator finds any problems in your feed, it will give you messages for each type of problem and highlight where the problem first occurs in your feed.
