The prospect's Audits tab shows the history of changes made to the prospect's record, such as field updates, list changes, and assignment dates. These data points can help determine what updates were made during the database clean-up project and how they affected the prospects. The Lifecycle Report, the amount of time the prospect spent viewing the website, and the unique clicks are not data points that can be found in the Audits tab, but they can be found in other reports or tabs in Marketing Cloud Account Engagement.
