Channel Adstock Decay

How to Interpret Adstock

Adstock, or carryover, measures the "half-life" of your advertising.

  • Fast Decay (e.g., Channel 1): These are typically performance-focused channels where the user is prompted to act quickly. The effect is strong but fades fast.
  • Slow Decay (e.g., Channel 3): These are often brand-building channels like TV or broad-reach video. Their impact on consumer memory and consideration lasts for several weeks.
  • Strategic Implications: Understanding adstock helps in planning the right frequency for your campaigns. A channel with fast decay needs more frequent, "always-on" support, while a channel with slow decay can support more spaced-out, high-impact flights.
