Ad Change Tracking
Ad change tracking is the practice of recording every configuration change across ad accounts — who changed what, when — in a permanent, queryable record, because the platforms' own change histories are thin, short-lived, or missing.

Ad change tracking is the practice of recording every configuration change across your ad accounts — budgets, bids, audiences, creatives, rules, settings — with who made it and when, in a permanent record you can query later. It exists because the platforms' own change histories are thin, short-lived, or missing entirely.
Why the platforms don't solve this
Native change histories vary from partial to nearly absent. LinkedIn's is the thinnest of any major platform (see the LinkedIn change history problem), and retention windows on other platforms mean history disappears on the platform's schedule, not yours (see why ad platforms forget). Meanwhile automation — Advantage+, Performance Max, Smart Bidding — makes changes no human logged.
What a real change record includes
| Dimension | Captured |
|---|---|
| What changed | Setting, campaign, ad set/group, creative, budget, bid, audience, rule |
| Who/what changed it | Named user, automated rule, or platform automation |
| When | Timestamped, in sequence, permanently retained |
| Effect | Which metric moved afterward — and whether the change caused it |
Why it matters
When a metric moves, the first investigative question is "what changed?" Without a record, that's archaeology across four platforms; with one, it's a query. It's also the evidence layer for agencies ("was it us or the platform?") and for governance (see the case for an ad-account audit trail).
