Article usefulness rating allows users to mark articles useful or not useful and help you improve your content.
At the bottom of each knowledge base article users will see a question:
Was this article helpful?
They can click on Yes or No button to cast their vote.
Users can also leave their feedback in a comment and clarify what they need or would like to see fixed.
Open an article in the admin panel and click on the Voters tab to see who rated it and how.
Article usefulness rating can be turned on or off on the Settings > Knowledge Base page in the admin panel.
