If there's one feature every Google Ads advertiser should know about, it's the Change History. It's a complete audit trail of every modification made to your account — and it's been quietly sitting there the whole time.
Whether you manage your own account or pay an agency, understanding Change History gives you a level of oversight that most advertisers don't have.
What is Google Ads Change History?
Change History is a built-in log inside every Google Ads account. It records every action taken: keyword additions, bid adjustments, ad copy changes, campaign settings modifications, budget updates — everything.
Each entry includes:
- Date and time of the change
- What was changed (the category and specific element)
- Who made the change (a specific user email or "Automated")
- The before and after values (where applicable)
Think of it as your account's CCTV. Nothing happens without being recorded.
Where to find it
In the Google Ads interface, click "Change history" in the left-hand navigation panel. If you can't see it, try the search bar at the top of the page and type "change history".
You can filter by:
- Date range: Last 7 days, 30 days, 90 days, or custom
- User: See changes by specific team members
- Change type: Filter by bids, keywords, ads, etc.
Change categories explained
Not all changes are created equal. Here are the main categories you'll see and what they mean:
| Category | What it means | Why it matters |
|---|---|---|
| Keywords | Adding, removing, or modifying keywords | Shows whether your targeting is being refined |
| Negative Keywords | Blocking irrelevant search terms | Critical for reducing wasted spend |
| Ad Copy | Creating or editing ads | Indicates active testing and optimisation |
| Bids | Adjusting how much you pay per click | Important but often automated; less valuable alone |
| Extensions | Sitelinks, callouts, structured snippets | Improves ad real estate and click-through rate |
| Audiences | Targeting or excluding audience segments | Shows sophistication in targeting strategy |
| Settings | Campaign-level settings (budget, schedule, location) | Usually infrequent; important but not a sign of active management |

This is the single most important distinction in your Change History. Google Ads makes many changes automatically:
- Smart Bidding adjustments — automated bid changes based on machine learning
- Auto-applied recommendations — Google implementing its own suggestions
- System changes — policy updates, format changes, etc.
These automated changes happen regardless of whether anyone is managing your account. So when your agency says "we made hundreds of changes this month", ask them to separate the human ones from the automated ones. The human changes are what you're paying for.
An account with 500 automated changes and 5 human changes is an unmanaged account with a busy algorithm.
How to export your Change History
- Go to Change history in Google Ads
- Set your date range (we recommend 90 days)
- Click the download icon in the top-right
- Choose CSV format
- Open the file or upload it to an analysis tool
The CSV gives you the raw data, which is much easier to analyse than scrolling through the web interface. You can sort, filter, and count changes by category, user, and date.
What to look for
When reviewing your Change History, focus on these questions:
- Are there human-initiated changes every week? Gaps of more than a week suggest neglect.
- Are multiple categories being touched? If only bids are changing, the management is shallow.
- Are negative keywords being added regularly? This is the clearest sign of active search term management.
- Is new ad copy being tested? Stale ads mean no one is optimising your messaging.
- Is activity consistent or clustered? Consistent weekly activity beats cramming before a monthly call.
The bottom line
Your Change History doesn't lie. It's the objective record of what's happening in your Google Ads account. If you're paying an agency to manage your ads, the Change History is where you hold them accountable.
You don't need to be a Google Ads expert to read it. You just need to know what to look for — and now you do.
