I’m not sure if this feature is new or not, but it certainly makes validating all of the links in a Canvas course easy to check.
Start by logging into Canvas and going into the course you want to validate. In the left navigator, click on the “Settings” link:
On the Settings page, look in the right navigator for the “Validate Links in Content” link and click on it.
From the Course Link Validator page you can click on the button to start validating all of the links in all of your content in your course. It may take a few minutes for it to complete, so be patient.
Once completed, you will see a list of all of the content with the associated links that are broken. You can then restart the link validation after you fix and links that the validator finds are broken.
I hope this helps you in developing quality Canvas course shells.
