Click the Start Link Validation button.
If any links are found in the course, Canvas displays the number of links [1], followed by the name of the content item and the content's associated invalid link(s) [2].
A link with the Deleted tag [1] means the linked content has been deleted from the course.
Links without tags [2] are invalid or unresponsive links.
To include links in unpublished course content, click the Show links to unpublished content checkbox [1]. The page will update the linked content to show any broken links in unpublished content, indicated by the unpublished tag [2].
To update links within course content, click the name of the content item [1].
After you update your content, you can check validate your links again by returning to the Link Validator page and clicking the Restart Link Validation button [2].
