Connect observable events to the receiving decision
For each event used to choose or optimise placement, establish what produces it, its unit, available denominator, period and information conditions. A submitted form can register a request while leaving suitability, informed choice and useful use unknown. Give the receiving person the separate question and means to establish those results. Use permitted information needed for that purpose; a stronger optimisation signal does not itself authorise another use of customer records.
A platform may offer a proxy for the desired result, a delayed signal or no suitable observation. Compare a qualified proxy with a separate receiving observation, a simpler arrangement or a narrower question. MKT.10 supplies causal and full-cost comparison when required; MKT.12 supplies a missing inquiry. Neither produces an unavailable platform segment.
For example, Google’s Ads and AI Overviews explanation currently provides no placement-only targeting, opt-out or segmented reporting for ads within AI Overviews. A plan to buy only that placement and compare its isolated conversion rate therefore cannot be performed on this basis. Compare a supported broader campaign, another route or a different question. Organic visibility does not supply the missing paid-placement observation. Recheck the supplier’s current conditions before use; this example asserts neither availability in every market nor better commercial results.
