Use when someone wants the target CPA or ROAS moved and you need to say what that will actually cost.
smart-bidding-target-change-plan.md
You are a paid media analyst planning a bid strategy change. You are not writing ad copy or restructuring the account.
Campaign, current bid strategy and current target: {{CURRENT_STRATEGY}}
Eight weeks of data as rows of week, spend, conversions, conversion value, average CPA, impression share lost to budget and to rank: {{WEEKLY_DATA}}
The change being asked for and who is asking: {{REQUESTED_CHANGE}}
Business constraints such as payback period, minimum volume and seasonality: {{BUSINESS_CONSTRAINTS}}
Produce:
1. A readiness check from {{WEEKLY_DATA}}: weekly conversion volume, week to week variance, and whether there is enough volume for the strategy named in {{CURRENT_STRATEGY}} to learn. Under 30 conversions a month, say plainly that the target is noise.
2. What {{REQUESTED_CHANGE}} trades away, as a direction only: volume, cost per conversion, impression share, auction position.
3. A staged plan table: Step, Target value, Days to hold it, What to watch, Abort condition. No step may move the target more than 15 percent.
4. Where {{REQUESTED_CHANGE}} conflicts with {{BUSINESS_CONSTRAINTS}}, and which of the two has to give.
5. A short note in plain language on why the change cannot be judged inside a learning period.
Rules:
- Do not forecast a CPA or ROAS figure. Direction and reasoning only.
- Calculate nothing absent from the data. Write "not supplied" instead.
Replace each placeholder with your own detail. The more specific you are, the less the model invents.
When do I need a plan rather than just changing the target?
When somebody has asked for the target to move and you need to state the cost before it happens. Typing a new number takes a second and the argument arrives three weeks later. This gives you a readiness verdict, a staged sequence and abort conditions, which is a document you can agree with the requester in advance.
What do I need in front of me?
Eight weeks as weekly rows, including impression share lost to budget and to rank, rather than a blended average. Week to week variance is what decides readiness and an average erases it. Add {{BUSINESS_CONSTRAINTS}} such as payback period, minimum volume and seasonality, since the requested change is tested against exactly those.
What does it return?
A readiness check on weekly volume and variance, the direction of what the change trades away, a staged table of target values with hold times and abort conditions, the conflicts with your constraints, and a plain note for whoever asked. It will not forecast a CPA or ROAS figure, deliberately. Agree the abort conditions first.
What is the mistake?
Making the whole move in one step and then reading the result inside the learning period. Each step is capped at fifteen per cent for that reason, and each hold should cover a full conversion cycle rather than a tidy calendar week. Under thirty conversions a month the target is noise, and the readiness check says so.
