What is the 3 3 3 rule in marketing?

The “3‑3‑3 rule” in marketing is an informal heuristic that says prospects typically see content fast, remember little, and act only if value is immediately obvious. One interpretation: you have about three seconds to catch attention, three minutes of light engagement to earn trust, and roughly three follow‑ups before interest fades. Marketers use this kind of guideline to design concise messaging, frequent but non‑spammy touchpoints, and clear calls‑to‑action across campaigns.
