What changes were made to my campaigns and can I undo them?

Use the Change History tab to review changes to your campaigns and undo changes to campaigns, ad groups, keywords and ads. Use the graph to quickly see how the changes affect your selects or other metrics.

Have you ever wanted to go back in time to stop yourself from making a change to your campaigns, ad groups, ads or keywords? Do you wonder if the decrease in selects was caused by a certain change?

With change history, you can see each action made to your campaigns in the last six months and compare that to the changes in key performance metrics, like selects or impressions. If you find a change that was made in the last 30 days that you wish you didn't make and it meets the eligibility requirements, you can undo that change.

Changes to campaigns, ad groups, ads and keywords that are eligible to be undone have an arrow button in the Undo column. Only changes made in the last 30 days can be undone. If a change can't be undone, the column will be empty.

The changes that can be undone are:

  • Campaigns: Bidding scheme, Budget amount, Budget type, Conversion goal (added/deleted) Name, Status (Note: Undoing the deletion of a campaign will set your campaign back to its original status—active or paused), Tracking template.
  • Ad groups: Bid (Search/Content), Bidding scheme, Name, Status, and Tracking template.
  • Ads: Ad title, Ad text, Display URL, Final URL, and Status.
  • Keywords: Bid, Bidding scheme, Final URL, Match type, Mobile final URL, Param1, Param2, Param3, and Status.
  • Standard text ads: Status
  • Expanded Text ads: Bidding scheme, Description, Final URL, Mobile final URL, Path 1, Path 2, Status, Title part 1, Title part 2, and Tracking template.


    After February 1, 2023, you will no longer be able to create new or edit existing expanded text ads. For more information, see About responsive search ads.

  • Dynamic Search Ads: Description, Path 1, Path 2, Status and Tracking template.
  • Audience Ads: Business name, Description, Final URL, Landscape Image, Landscape logo, Long headline, Mobile final URL, Short headline, Status, Square image, Square logo, Title, and Tracking template.
  • App Install Ads: Description, Final URL, Status, Tracking template, and Title.

  • Administrator will show in the Date & Time/User column when Microsoft Advertising completes a system-generated change. For example, Microsoft Advertising automatically pauses your campaign when your budget is depleted and then activates the campaign when the budget is replenished.
  • The graph can display up to 200,000 changes. Narrow your results by selecting different change types, a shorter date range, or specific campaigns or ad groups.
  • It can take time for the summary table to show that the change was undone.
  • In a rare circumstance, we might not be able to undo the change even if you selected the arrow button because an action associated with the change has already been deleted. We will let you know if we can't undo the change.
Use the graph to see the relationship between change history and key performance metricsexpando image

Since you can see how each of your changes impacts your campaign’s performance with the change history graph, you can also quickly identify which type of changes have the greatest impact on your campaigns. For example, say you saw a significant rise in selects to your online ad. What happened? Was it something you did? Use this graph to find out what you’ve done that works, and adjust what doesn’t.

  1. From the collapsible menu on the left, select All campaigns > Change history.

    If you're using the new Microsoft Advertising navigation, from the navigation menu on the left, hover over Campaigns and select Change history.

  2. If the graph is closed, select the show graph toggle to open it. It remains open until you close it.
  3. Select the metrics you want to see on the top right of the graph. Each metric is a different color line.
  4. Select the time period on the top right of the graph.
  5. To see the number of changes made on a specific date, hover over a change history marker on the line.
  6. To filter what changes you see in the table, select a change history marker in the graph.
