What Is AdTech?
AdTech is short for advertising technology, a broad term that covers tools and software used to target, deliver, and analyze digital advertising. It includes platforms like demand-side platforms (DSPs), data management platforms (DMPs), and ad exchanges, all aimed at optimizing ad performance and audience reach.
Core AdTech Infrastructure

Ad Servers
Ad servers form the backbone of the digital advertising technology ecosystem. They deliver ads to websites, apps, and other digital platforms.
Purpose and functionality:
- Content delivery and rendering
