Ad Account Audit Trail: Change Tracking Across 5 Platforms
An ad account audit trail that outlives platform limits: a permanent, version-controlled change record across Google, Meta, LinkedIn, TikTok, and Reddit.
Updated July 2026.
An ad account audit trail is a permanent, timestamped record of every change made to an ad account: who made it, what it was (old value and new value), and when it happened. No ad platform actually provides one — Google Ads keeps two years of change history, Meta's log is commonly reported at around 90 days, and LinkedIn Campaign Manager has no change history at all. The Ad Spend maintains an independent, version-controlled audit trail across Google Ads, Meta, LinkedIn, TikTok, and Reddit.
What an audit trail for ad accounts should record
Three fields, for every change, forever:
- Who. The user — or the automation. Automated rules, API calls, and editor tools change accounts constantly; an audit trail that only tracks humans is half a trail.
- What. Not “budget edited” but the diff: old value, new value, on which campaign, ad set, or keyword. Version-controlled, like code.
- When. A timestamp precise enough to line the change up against the performance data around it.
Get those three, keep them permanently, and most Monday-morning fire drills become a thirty-second lookup. Miss any of them and you're back to interviewing coworkers.
Why platform change logs aren't an audit trail
The platforms keep change data for their convenience, not your governance. The gaps are documented:
| Platform | Native change log | Retention |
|---|---|---|
| Google Ads | Yes — Change History page | 2 years in the UI; 30 days via the API's change_event resource |
| Meta | Yes — Account Overview → Change History | ~90 days, per third-party documentation; Meta publishes no official window |
| No change history feature; workaround is filing a support ticket | — |
We've written the long versions: the ad account audit trail makes the case in full, and the LinkedIn ads change history problem covers the platform where the gap is total. The pattern is the same everywhere: the record is short, siloed per platform, and silent — no platform notifies you when a change happens.
The Ad Spend records changes on all five platforms it monitors into one place, from the moment you connect, with no expiry. Retention isn't subject to a platform's policy change, because the record is yours.
“What did the previous agency change?”
Every agency handoff starts with the same forensic exercise: the new team inherits an account shaped by decisions nobody documented. Bids that make no sense until you know they were a Black Friday patch. A negative keyword list with a mystery entry blocking a converting query. With a permanent audit trail, the handoff question has a literal answer — scroll the record, filtered by user and date, old values and new values intact.
It works in both directions. Outgoing agencies get protection too: when performance dips two months after handoff, the record shows exactly what changed after they left. For agencies running The Ad Spend, each client is its own org, so every client's trail stays cleanly separated.
Change tracking is governance, not archaeology
An audit trail you only open during incidents is a smoke detector you check after the fire. The point of change tracking is the operating discipline it enables — the subject of marketing governance in 2026. In The Ad Spend, that discipline is built in: accounts are checked roughly every six hours, change alerts land in Slack with the who, what, and when, and any suggested fix runs through a governed approve-then-execute workflow — nothing executes until a human approves it in the app or Slack, and every approval is itself logged. The audit trail covers the tool's own actions, not just the platform's.
Connecting takes each platform's own OAuth login — no API keys — and the initial sync pulls in a few months of history (see connecting ad accounts). From that moment, every change on every connected account is on the record, permanently. Start with the free tier's performance and budget pacing alerts at The Ad Spend.
FAQ
What is an ad account audit trail?
A permanent, timestamped record of every change to an ad account — who made it, what changed (old and new values), and when. It differs from native platform change logs, which expire (2 years on Google Ads, roughly 90 days on Meta) or don't exist (LinkedIn).
Do ad platforms provide audit trails?
Not really. Google Ads keeps two years of change history in the UI and 30 days via API. Meta's change history is commonly reported at about 90 days. LinkedIn Campaign Manager has no change history feature. None of them notify you when changes happen.
How do agencies use an independent change record?
Two main ways: handoffs — answering “what did the previous agency change?” with actual diffs instead of guesses — and protection, proving what they did and didn't touch. In The Ad Spend, each client is a separate org, so records never mix.
Does The Ad Spend's audit trail cover automated changes?
Yes. It records changes regardless of source — users, automated rules, API tools — and it logs its own governed actions too: any fix suggested by the system must be approved in the app or Slack before executing, and the approval is logged.
