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!

1. Feedvalidator.org


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 is the W3C Feed Validation Service, a free service that checks the syntax of Atom or RSS feeds. The Markup Validation Service is also available if you wish to validate regular Web pages.

3. Experimental RSS 1.0 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.

4. Validome – Feed Validation

5. RSS Validator

  2. My rss feed is showing some errors, i dun know how to go about correcting them.Kindly guide.


  3. I have seen there are couple of feed validators available in the internet. But why do we need them? Any specific purpose, or just to make our mind more confusing about RSS feeds? 

  4. It's very important post for me, I didn't think about it before. Now, need to check all of my feeds.
    Thanks a lot for sharing

  6. 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…

    1. w3c is a standard, i use it to test my custom CMS or non-wordpress sites all the time. if its a w3c pass, it will most likely do good on most platforms. however, the more you check the better it is 🙂

  7. 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?



    1. CommentLuv detects all the available feeds dood! So you don’t need to worry about that! 🙂

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

      1. 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!
