Change History Checker

Problem it solves:

Business owners paying an agency have no way of knowing if their agency is actually making changes — or what those changes are. This is one of the most emotionally charged pain points in the market. Equally important: if your account is being managed by multiple people, unauthorised changes can cause serious damage without anyone noticing.

What it does:

•       Runs daily and emails an alert whenever any change is made in the account

•       Logs: who made the change, what entity was changed (keyword, bid, budget, ad, campaign setting), what the change was, and when

•       Distinguishes between human changes and Auto-Applied Recommendation changes

•       Weekly summary email of all changes made that week — even if no alerts fired

•       Covers: bid changes, budget changes, campaign status changes, ad additions/removals, keyword additions/pauses, negative keyword additions, audience changes

Why it matters for the agency oversight audience:

If you pay an agency £1,000/month and this script runs for 30 days with zero activity logged, you have documented proof that nothing was done. If activity was logged, you can verify it was sensible. Either way, you know. This is the agency accountability tool.

Output:

Daily email alert (only when changes occur) + weekly summary email regardless.

Runs:

Daily at 08:00. Weekly summary every Monday.
