From internship to full-time work, I’ve encountered various advertising systems of different sizes—from small DSPs that are “small but complete,” to large media platforms that bundle SSP, ADX, and DSP together. This has given me a preliminary understanding of the advertising systems in the industry. Taking advantage of the May Day holiday, I’m organizing my current knowledge of advertising systems. Since the concept of an advertising system is vast and involves many components, I cannot cover everything comprehensively. This article mainly describes several aspects I care about from multiple perspectives (technical, business, product) in a concise manner. The content may not be complete—feedback and corrections are welcome.
Disclaimer: The content of this article is unrelated to my employer and is mainly based on my current understanding. I will only reference public information and will not involve any unpublished internal information from my employer. If any colleagues find sensitive content, please contact me for removal. In today’s era of open source, widely available papers, and increasing personnel mobility, I believe these general techniques are not the core—data + understanding of business + flexible assembly of these general techniques is what matters.
