Change history is a tool that lists the changes you've made to your account during the past two years. View details about changes like when you paused your campaign, who added a keyword, and the amounts of your previous budgets.
- You can view all changes for a particular date range, filter the results by the type of change (such as budget adjustments or keyword edits) or view changes for a particular campaign or ad group.
- The change history tool shows each change within a timeline, mapped to your account data like impressions, clicks, conversions, click-through rate and cost. Compare your changes with the timeline of performance data to help know which changes may have contributed to changes in your performance.
- If you've given other people access to your account using their own login, you can also use the tool to view who made certain changes.
