Users can vote on your portal Knowledgebase articles.
It's a good idea to monitor these ratings to find and improve articles that are rated unhelpful.
You can use this custom report to find articles that have been rated poorly by users.
SELECT articles.title, articles.id, articles.total_rating
ORDER BY articles.total_rating ASC
To use this:
1. Go to the Reports interface, then Stat Builder (your account may not have access to use reports, so you may need your admins to grant you access or run the report for you).
2. Click Add.
3. Under Query Builder and paste in the code.
