How do I validate links in a course?
As an instructor, you can verify all external links throughout your course to ensure they are valid. You can check these links using the course link validator, which searches through course content and returns invalid or unresponsive external links in both published and unpublished content. However, please note that some links flagged as unresponsive are inaccessible by Canvas servers and will still work for students.
The link validator also includes deleted links. Deleted links are links that are still in the course, but their linked content has been deleted (such as a course file or page).
If the link validator does not detect any broken links in your course, Canvas may display a celebration. The link validator celebration feature option must be enabled by an account admin. However, you can disable link validator celebrations in your user settings.
Note: The link validator does not validate mailto (email address) links.
In Course Navigation, click the Settings link.
Open Validation Link
In the sidebar, click the Validate Links in Content link.
Start Link Validation
Click the Start Link Validation button.
If any links are found in the course, Canvas displays the number of links , followed by the name of the content item and the content's associated invalid link(s) .
View Unpublished Content
By default, the Show links to unpublished content checkbox is selected . The page will display any broken links in unpublished content .
View Broken Link Details
The validator displays broken links and images by item type . Broken content is identified as either a link or an image . Non-existent content means that the object is invalid and should be replaced . Unreachable objects mean the image could not be displayed .
Note: Course Cards are a supported object type. Any deleted course image added from Flickr displays as an invalid image.
To update links within course content, click the name of the content item .
After you update your content, you can validate your links again by returning to the Link Validator page and clicking the Restart Link Validation button .
