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.

2. W3C Validator

This prototype is based around a Schematron schema for validating RSS 1.0. The schema is used to generate an XSLT stylesheet which performs the actual validation. In this version of the validator the validator produces a simple HTML report listing the errors, as well as copy of the original RSS 1.0 file.

    • Directory Sieve

      for wordpress we won’t require feed validators, however if its a custom CMS and it allows feeds then its time that we test it on the validators and see if there is any error or compatibility problems…

    • Net Age | Web Design

      Nice informative article, which leads me to ask the following question – What feed do you need for CommentLuv? Then the CommentLuv link at the bottom of your comment – does that change every time you update with a new post / content, right across the board? Meaning does the link at the bottom of every comment change every time, including your old comments?



      • S.Pradeep Kumar

        CommentLuv detects all the available feeds dood! So you don’t need to worry about that! πŸ™‚

        And the link won’t change. It will display the recent article at the time you post the comment and it will last forever!

        • Net Age | Web Design

          Thank you for the information, Pradeep. You have been most helpful. It sure is worth adding a feed to your website, especially if you got regular fresh content coming!
