Knowledge Health score
The Knowledge Health Score measures the quality of knowledge articles and your knowledge bases using weighted scan metrics. The score helps you to identify and resolve content gaps that affect discovery and user trust.
Benefits
Governance at the knowledge level- the roll-up score gives leadership insights about knowledge quality in the home page.
Visibility into content quality at scale- instead of manually auditing hundreds of articles and KB-level scores give an immediate signal of where quality is degrading.
In-context feedback- The right-side panel shows exactly which parameters are pulling the score down while the author is already in edit mode.
Prerequisites
You must enable the Enable article health score calculation property and Enable article optimization recommendations skill to view knowledge health score.
How the Knowledge Health Score is calculated
Each knowledge article is scanned against seven quality parameters and assigned an article health score from 0 to 100. Knowledge Base scores are the average of all article scores within that Knowledge Base, and the score is the average of all aggregated Knowledge Base scores. See Article health score for the full parameter breakdown and weighted calculation.
Score aggregation across levels
Article scores aggregate upward through two additional levels:
-
Article Health Score
The article health score is a numeric value from 0 to 100 that represents the quality of a single knowledge article. It is calculated by scanning the article against six quality parameters and computing a weighted average of the results.
-
Knowledge Base health
The average of all article health scores within a Knowledge Base selected by the user.
-
Aggregated Knowledge Base score
The average of all Knowledge Base scores across the Knowledge Base. This is the score displayed on the Knowledge Management homepage gauge by default.
A change to a single article score propagates upward: improving an article raises its Knowledge Base score, which in turn affects the average score appearing in the home page.
Knowledge Base health
The Knowledge Base health view provides a filtered, drill-down view of health scores across the knowledge bases you have access to. Use this view to identify which knowledge bases and articles need attention and to navigate directly to articles that require fixes.
The view contains three sections:
-
Needs Attention
Displays a health score indicator for the selected Knowledge Base and a set of top six issue cards, one for each scan parameter. Each card shows the parameter name and the number of articles affected by that finding. Select a card to filter the Articles list to only the articles affected by that parameter. The section updates dynamically when you change the Knowledge Base filter.
Displays a duplicate articles card, showing the duplicate health score and topics needing attention. Select Review Duplicates to go directly to the articles that need fixes.
-
Knowledge bases
Lists the knowledge bases you have access to.
Column Description Knowledge Base Name of the Knowledge Base. Description Brief description of the Knowledge Base. Owner User responsible for the Knowledge Base. Health score Aggregate health score for the Knowledge Base. -
Articles
Lists knowledge articles across the selected Knowledge Base.
Column Description Article Title of the knowledge article. Short description Brief description of the article. View count Number of times the article has been viewed. Knowledge base Knowledge base the article belongs to. Health score Health score for the individual article. Select an article to open it and navigate to the edit view to improve its health score.
