What an 8.8 M‑User Experiment Shows About the True Limits of Agent‑Based Marketing

A longitudinal study of 8.8 million users over 11 months demonstrates that while agentic marketing can sustain performance after human optimization stops, its gains eventually decay, highlighting the emerging “Agentic CDP” model where AI handles baseline decisions while humans drive growth.

Why Simple Click Counts Fail: Smarter Scoring Strategies for Content Recommendation

The article recounts a junior engineer's journey improving a news app's recommendation system, moving from naive click counts to recent clicks, CTR, lower confidence bounds, and advanced multi‑armed bandit techniques like UCB and Thompson Sampling to balance relevance and novelty.
