The most direct and quantifiable measure of how often call center agents use Knowledge articles is by tracking how many times an article is attached to a Case. This action explicitly links an article to the resolution of a specific customer issue, providing a clear metric for usage frequency. A report that counts the number of cases each Knowledge article is attached to will accurately identify the most frequently used articles by the support team.

A. Knowledge articles with the most revisions: The number of revisions indicates how often an article's content is updated or modified, not how frequently it is viewed or used by agents to solve cases.

B. Knowledge articles with the highest ratings: Ratings measure the perceived quality or helpfulness of an article, not its usage volume. An article for a rare issue could have a high rating but low usage.
