Please consider adding more details to the Article Revision or Article banner details to include a date the article was hidden to improve workflow efficiencies. The current options are not efficient, especially when through the maintenance of broken links. If an article that is hidden has a broken link, it still shows up on the report. If the article is extremely outdated,d there is no way to view this information other than using the Team Audit features when other team members have hidden the article from view.
In this case, please navigate to Settings > Knowledge base portal > General > Team auditing > Now click on 'Events' filter > Then type Article visibility changed. Now you can export the events and confirm on which date the article was hidden.
For smaller Knowledge teams, this is not an efficient workflow and is quite time-consuming.
Perhaps a good place to add this visibility would be to the banner that is present on the Hidden article.
