How does the tool detect broken links in my video descriptions?

To detect a broken link in a video description, we use different methods:

• we have a static analysis to find if a link is malformed
• we have a dynamic analysis that "clicks" on every link found in order to check if it the link leads to a valid page on the internet
• we also have a set of analysis that can detect if the website targeted by a link is a valid website or not

We are constantly improving our detection methods to provide the best possible service to our users.
