Monitoring your Google Ads campaigns is key to maintaining performance and catching problems before they compound. One of the most underutilized tools for doing that is change history, but combing through hundreds (or thousands) of entries to find a specific change is its own kind of headache.
In this post, we’ll walk through how Platform Change History helps you catch changes you didn’t make, check your team’s work, and investigate performance drops without manually combing through the full log.
What is the Platform Change History tool?
Platform Change History is a tool inside Optmyzr that gives you a unified view of every change made across all your Google Ads accounts in one place.
The tool can be found under Utilities in the Optmyzr menu, or via Optmyzr Explorer → Entities → Platform Change History. It’s currently available on request, so reach out to support@optmyzr.com to get access.
How the Platform Change History tool helps you monitor your PPC account
1. Catch changes made by auto-apply recommendations
Auto-apply recommendations can make changes to your campaigns without your knowledge. Platform Change History lets you filter by source to isolate changes made by auto-apply, so you can review them and make sure they align with your overall campaign strategy.
Some of the changes you should look out for:
Removing redundant keywords: This might lead to converting keywords being removed. It’s important that you make the call on which keywords to keep. This recommendation triggers based on the rules of close variants, so analyzing what Google sees as redundant will help with account structure.
Adding in ad copy/assets: Creative isn’t automatically better because a human made it. However, brand standards might dictate certain language.
Adding in broad match keywords: Broad match can be useful and when used correctly, absolutely helps improve account performance. Changing existing keywords to broad match or adding broad match where it hasn’t been planned for can hurt the account because keywords have been removed and you might now be bidding against yourself.
Adding in search partners: While search partners can be useful, it often represents unknown inventory. Additionally, because it’s a campaign-wide decision, it typically requires human investigation to determine if it’s worth testing.
2. Check the impact of work and catch changes you didn’t make
Platform Change History shows you who made each change and which platform it came from, so you can filter by user or source to get a clear picture of where changes are originating across all your accounts.
This is useful in two ways. First, you can verify what your own team has been doing, checking that no unexpected changes were made to important campaigns and that the work being done is strategic rather than superficial. For example, if you see that most of the changes are IP exclusions and there aren’t any ad copy, negative keyword, or placement changes, you might investigate whether practitioners are actively working on the account.
Second, for agencies managing accounts where clients also have direct Google Ads access, the filter-by-user view helps you quickly identify whether a change came from your agency or was made directly in the Google Ads UI by the client. If performance dips unexpectedly, you can pinpoint the source of the change and have an informed conversation with your client before spending hours diagnosing a problem that was already created, or solved, on their end.
3. Analyze changes during declining performance
If you notice a decline in performance, Platform Change History lets you filter by date range to narrow the log to the exact window you care about. You can see the precise details of what changed, including the old value and the new value, making it easier to connect a specific change to a shift in performance and take corrective action.
And if you’d rather not manually work through the filters, Ask AI lets you query the log in plain language. Something like “What changes were made to this campaign in the last two weeks?” gets you straight to the relevant entries without digging through the full log.
