What feature can a client use to track changes to a page over time?

The feature that allows a client to track changes to a page over time is versions. In Adobe Experience Manager (AEM), the versioning system enables the management of different iterations of content. Each time a change is made to a page, a new version can be created, allowing users to view and restore previous versions if needed. This is particularly useful for auditing changes, maintaining content integrity, and allowing team members to collaborate without losing earlier content states.

In contrast, workflows typically manage processes and tasks related to content approval and publishing rather than specifically tracking page content changes. Scheduling is focused on setting times for content to be published or unpublished but does not handle version control. Analytics reports generate insights into visitor interactions and behavior on the page but do not record past content changes. This makes versioning the most suitable feature for tracking page changes over time.
