Signal Decay Window

Signal Decay Window treats every competitive data point as perishable: ad spend figures, traffic estimates, and keyword rankings lose strategic value at different speeds. Display creative from Adbeat can be actionable for weeks, while Similarweb traffic estimates shift meaningfully inside a quarter. The framework asks agencies to timestamp every insight and assign a decay rate before it enters a client deliverable. A pitch deck built on six-week-old spend data reads as stale to a sophisticated buyer. The practical move is a two-tier intelligence cadence: fast signals (creative rotations, new placements) reviewed weekly, slow signals (share of voice, category spend trends) reviewed quarterly. Agencies that publish their refresh cadence in the retainer agreement convert a data-access commodity into a reliability promise, which is harder for a client to price-shop against a cheaper dashboard seat.
