What is Signal Decay Half-Life?
“Signal age → action window”
Signal Decay Half-Life is the working estimate of how long a detected trend stays useful for a client before it becomes common knowledge and stops conferring advantage. Every monitored signal has a shelf life: a competitor page change caught by Visualping may be actionable for a week, while a topic surfaced by Exploding Topics 12 months ahead of mainstream adoption holds value far longer but with lower confidence. Agencies that never estimate half-life end up pitching stale insight on retainer calls, or worse, treating a two-day spike as a durable shift. The discipline is to tag each signal with a decay estimate at capture, then route fast-decaying items to immediate delivery and slow-decaying ones into quarterly strategy work. Deduplication matters here too: Scoopkit collapsing near-duplicate AI headlines into one event record stops a single story from looking like a trend through repetition.
