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.

Before you buy
Why would I need a change log?
To know what is actually happening in your account. If an agency or team manages it, this shows you every change they make, when, and who made it. If performance shifts, you can see what changed right before. It is proof of work and a way to catch unexpected edits.
What does it flag as unusual?
It surfaces changes worth a second look, large edits, sudden bulk changes, or activity that stands out from the normal pattern. Rather than reading a raw log line by line, you get the notable changes pulled to the top so you can check them quickly.
How does this help me check my agency?
It gives you an independent record. Instead of taking an agency's word on the work they are doing, you see the actual changes in the account, dated and attributed. It is a simple, factual way to verify you are getting the management you pay for.
