Change history is a tool that lists the changes made to your account, campaigns, and ad groups during the past 2 years. Data older than 2 years won't be available. 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 , clickthrough 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.
- The "User" column will show the email address of the person who made the change if it was done through the Google Ads interface.
- Changes made by automated systems or Google's internal systems may appear under users like "ads-dartsearch-budget" or "Google Ads system".
- These are typically for maintenance or auto-generated targets and usually don't alter active campaign settings or performance. If you use SA360, '"ads-dartsearch-budget" changes might relate to system-derived budget bid strategy plan creations due to a "Plan schedule" setting, which can be disabled in SA360 plan settings. Changes made via the Google Ads API (for example, by a third-party tool) might show "Google Ads API" or a specific tool name in the user column.

If you're having trouble finding specific changes or believe the change history is incomplete, try clearing your browser's cache and cookies, or use an incognito/private browsing window. Sometimes, not all account-level settings changes or changes made by Google representatives during consultations are listed. If discrepancies persist, it might be a temporary display issue.
Note: The "Change history" page limits the details displayed for each change entry. To view all details, we recommend making smaller changes, ideally affecting fewer than 2,000 entities.
