Introduction

Programmatic advertising has quietly rebuilt itself over the last two years. The rules that shaped campaigns in 2022 barely apply in 2025.

The End of Third-Party Cookies (For Real This Time)

Manual bid strategies are largely gone. Machine-learning bidding now handles pacing, audience discovery, and creative rotation in real time.
