Use this worksheet when a campaign readout, attribution report, MMM, lift test, brand study, or attention dashboard is being used to justify a renewal, budget shift, scale, cut, repair, or stronger test.
The worksheet turns a meeting into an evidence record. It does not decide whether a campaign worked by itself. It makes the requested action, evidence rung, included rows, excluded rows, threshold, uncertainty, and next test visible before the recommendation is written.
Primary source trail and a simulated decision gate
This worksheet treats attribution as a credit-allocation record, not as proof that advertising caused the outcome. Google Analytics describes attribution as assigning credit to touchpoints on a path to a key event, while its data-driven model uses converting and non-converting paths. Google also documents that the selected lookback window controls which earlier touchpoints can receive credit. Those settings are important fields in the meeting record, but they do not replace a preplanned comparison or a clear counterfactual.
- Google Analytics: Get started with attribution - defines attribution and explains how data-driven attribution uses converting and non-converting paths.
- Google Analytics: Select attribution settings - documents the reporting model, creditable channels, and key-event lookback window.
- Google Ads: About attribution models - explains that the model changes conversion counting and can affect conversion-based bidding.
- Google Ads: About the Experiments page - describes splitting budget or traffic between an original campaign and an experiment for a defined comparison period.
Simulated worked example - not a live campaign: assume a meeting packet contains 12,000 qualified visits and 360 reported conversions, but only 300 are mature under the team's stated outcome window. A comparable prior period contains 10,000 qualified visits and 250 mature conversions. The current mature conversion rate is 300 / 12,000 = 2.50%; the prior rate is 250 / 10,000 = 2.50%; the observed rate ratio is 2.50% / 2.50% = 1.00x. The 60 immature conversions, any change in traffic mix, and the non-preplanned comparison cap the written recommendation at "retain or repair while planning a stronger comparison," not "the campaign generated lift" or "increase budget."
Assumptions and limits: the example assumes the visit definition, maturity rule, period comparability, attribution settings, and deduplication rule are known and stable. The conclusion changes if any of those fields change, or if an experiment shows a credible difference between comparable arms. Use the worksheet's Weakest material evidence lane, Result after exclusions or sensitivity checks, and Evidence request before the next budget change fields to expose those changes.
What the verified sources establish
Google Analytics documents attribution as a way to assign reporting credit across touchpoints; its model, eligible channels, and lookback-window settings can change how key events and conversions appear in reports. Google Ads likewise explains that an attribution model changes how conversion credit is counted and used for bidding. Its Experiments guidance describes splitting budget or traffic between an original campaign and an experiment for a defined period, then evaluating the comparison before applying a change.
Source-use boundary: those platform mechanics do not validate the simulated visits, conversions, maturity rule, business threshold, or any claim that the campaign caused incremental outcomes. A prior-period comparison is not an experiment merely because it is numerically comparable. The meeting owner must attach the underlying export or study record, state the attribution and lookback settings, and write the comparison design before treating a budget action as supported.
Simulated packet acceptance pass - not a benchmark
Score the example against the six worksheet gates below using 0, 1, or 2 only after writing the evidence used. A score of 2 means the field is inspectable and fit for the proposed meeting action; 1 means it is present but limited; 0 means it is missing.
| Gate | Example evidence | Score |
|---|---|---|
| Decision and scope | The meeting asks whether to retain or repair while planning a stronger comparison; the larger increase-budget action is not supported. | 2 |
| Source trail and row scope | Qualified visits and mature conversions are visible, but placement, creative, and excluded-row details are not attached. | 1 |
| Outcome maturity | 300 of 360 conversions are mature, but the example does not demonstrate qualification or deduplication. | 1 |
| Comparison design | A prior period is shown, but it was not a preplanned holdout or experiment. | 1 |
| Threshold and uncertainty | No interval, minimum effect, cost ceiling, or decision threshold is supplied. | 0 |
| Closeout and reversibility | Retain/repair is bounded, but an owner, due date, and post-action readout are not yet recorded. | 1 |
The reproducible total is 2 + 1 + 1 + 1 + 0 + 1 = 6 / 12 = 50%. Because the threshold-and-uncertainty gate is zero, the packet supports a retain-or-repair handoff and a stronger comparison request, but it does not support scale, cut, lift, or a new planning assumption. Re-score the same six gates after attaching the missing rows, threshold, owner, and closeout readout; the percentage is a packet diagnostic, not a universal quality bar.
Downgrade rules
| If the meeting finds | Downgrade to | Better next action |
|---|---|---|
| The recommendation depends on attributed conversions without a comparison group. | Observed response evidence. | Renew cautiously, repair tracking, or plan a holdout. |
| The strongest result is a small slice without minimum delivery or quality thresholds. | Directional comparison or weaker. | Retest with minimum cells and fixed slice rules. |
| A model rank changes materially when priors, exclusions, or calibration anchors change. | Directional planning evidence. | Use ranges, name assumptions, and require sensitivity review. |
| A survey result lacks sample source, balance, question wording, or uncertainty. | Weak survey evidence. | Request method detail before budget language relies on the result. |
| Outcome rows are still immature or missing buyer-side status. | Preliminary observed response. | Close the status window before final renewal language. |
Pair with
Use this worksheet after the advertising budget decision evidence ladder sets the evidence rung. Pair it with the measurement method selector before choosing a design, the next measurement method guide when the final action needs stronger evidence, the campaign evidence triage tree when the first weak lane is unclear, the uncertainty interval checklist when a threshold needs a range, and the campaign renewal memo template when the meeting result needs final action language.
