What this question tests
Domain knowledge of the ad tech ecosystem and its key players.
How to approach it
- Structure the answer around the buy side and sell side of programmatic advertising.
- On the buy side, name advertisers, agencies, and demand-side platforms (DSPs) that help advertisers bid on inventory.
- On the sell side, name publishers and supply-side platforms (SSPs) that manage and sell ad inventory.
- Explain the role of ad exchanges, which connect DSPs and SSPs in real-time bidding auctions.
- Mention data providers and verification/measurement companies, which supply targeting data and confirm ad viewability and fraud prevention.
- Summarize how a single ad impression flows through these intermediaries in milliseconds during real-time bidding.
What a strong answer includes
- Clearly separates buy-side (DSPs, agencies) from sell-side (SSPs, publishers) intermediaries, showing structural understanding.
- Names the ad exchange's specific role as the real-time auction connector between both sides.
- Explains data and verification providers as a distinct category, not lumped in with DSPs or SSPs.
- Describes the real-time bidding flow briefly to show end-to-end understanding, not just a list of terms.
Common mistakes
- Listing terms without explaining how they connect to each other in the transaction flow.
- Conflating DSPs and SSPs or ad exchanges.
Likely follow-up questions
- How has this ecosystem changed with rising privacy regulation?
