# Feed validation tool

Google maintains an
[open source feed validator](https://github.com/google/cap-library)
that provides specific feedback that you can act on beyond straightforward XML
validation.

To validate your feed, go to the
[CAP Validator](http://cap-validator.appspot.com/).

> [!NOTE]
> **Note:** The CAP feed validator is the most effective and efficient way to prepare your feeds for ingestion. We recommend that you run the validator on your feeds before you send them to Google.
