These terms describe different parts of the same campaign. Keep the distinctions clear when reading a report or discussing the next purchase. A metric can be useful for locating an issue without being the customer outcome that controls your budget.
Audience evidence
Information that supports your description of the intended customer situation. Product availability, existing customer questions or compatibility requirements can be useful. An audience label on its own does not prove that everyone reached will want the offer.
Value proposition
A plain explanation of the benefit, the intended customer and the reason the promise is credible. It should be understandable in the advert’s actual context and consistent with the receiving page and material product conditions.
Channel role
The specific contribution expected from a placement. An introduction, a comparison visit and a request for a quote are different tasks. Naming the role helps you select content and interpret what the campaign records.
Primary metric
Choose the primary metric to judge the purchase against its objective. Define whether success means a qualified enquiry, an activated trial or another accepted stage, and keep an early form event distinct from a confirmed customer.
Diagnostic metric
An observation that helps explain the main result. Delivery, landing activity and intermediate completion can reveal where the route changes. A high interaction rate is useful context, but it should not automatically overrule weak customer quality.
Conversion
A defined action recorded in your implementation. Its meaning depends on the actual event: a submitted form, order or activation can all be labelled a conversion. State which one you mean and how it is accepted.
Attribution
The assignment of credit to an observed interaction under a model and reporting window. It helps describe recorded journeys. Credited outcomes alone do not establish how many additional customers the advertising caused.
Incrementality
Measure incrementality as the additional outcome caused by an activity compared with what would otherwise have happened. A suitable comparison method is needed to investigate that difference. An ordinary campaign report showing an advert before an order does not establish proven lift.
Learning budget
The affordable commitment you make to answer the first buying question. Include the work needed to make the purchase interpretable. Keep account funding, the campaign allocation and the media bid as separate numbers.
Quality check
A check for a particular issue such as duplicate events, invalid delivery or ineligible leads. Different problems need different evidence. Commercially unsuitable responses are not automatically proof of fraudulent traffic.
Frequency
How often an exposure is counted for the relevant audience and period under the reporting definition. Use the actual supported controls and scope. Do not infer a complete individual exposure history from a campaign average.
Decision record
A short dated explanation of the setting changed, the reason and what happened afterwards. It allows the next buyer to understand a result without assuming that the current campaign configuration also describes its entire history.
