Engagement Signal Decay

Engagement Signal Decay treats every buyer interaction (a deal room open, a demo replay, a document download) as a perishable asset with a half-life measured in hours, not weeks. The framework asks one question per signal: how long until this observation stops predicting intent? A room revisit at 9am is actionable at 11am and noise by Thursday. Agencies that wire content creation to buyer engagement data inherit this clock whether they plan for it or not, because the retainer promise is pipeline velocity, not content volume. In practice, a shared workspace built in Arrows or a deal room in Dock can log a pricing-page dwell spike, but the signal only converts if a rep follows up inside the window. Forrester's AEO research makes the same point about discovery: answers mediate consideration before a click, so late response forfeits the deal.
