Find Change History in Google Ads Account

Change History is a built-in audit log in Google Ads that records every modification made to your account — including bid changes, budget edits, ad pauses, keyword additions, and more. It shows who made the change, what was changed, the old value, and the new value, along with a timestamp. It's invaluable for diagnosing sudden performance drops or unexpected account changes.

Google Ads stores Change History for up to 2 years. You can use the date range selector within the Change History view to look back at any period within that window, making it easy to audit changes from months ago.

Yes. Change History records the email address of the user who made each change. This is especially useful for agencies or teams managing a single account, as it lets you identify which team member updated bids, budgets, or creative without needing to ask manually.

Yes. Google Ads lets you filter the Change History log by change type — for example, you can show only budget changes, only bid adjustments, or only ad status changes. Use the filter bar at the top of the Change History page to narrow the results by type, campaign, or date range.

Yes. Automated changes — such as those made by Smart Bidding, automated rules, or Google's recommendations that you approved — are also logged in Change History. The log will show the change source as "Automated" or list the specific rule or recommendation that triggered it, so you maintain full visibility over all account modifications.

Change History is a read-only audit log — it does not have a built-in undo button for most change types. However, you can use the old and new values displayed in the log to manually revert a change. For some change types like bid adjustments or budget edits, you can simply re-enter the original value in the campaign settings.
