Question: What enables buyers of digital advertising inventory to manage multiple ad exchanges through one interface?
- Advertising platform
- Demand-side platform
- Keyword manager
- Targeted advertising manager
Explanation
A demand-side platform is the technology used to buy and manage digital ad inventory from multiple sources through one interface. HubSpot defines a DSP as an automated programmatic advertising platform that lets marketers purchase and manage inventory across many ad sources in one place. That centralization is the key difference between a DSP and a general advertising tool. The value is unified buying and management across exchanges, not keyword control or a generic targeting feature. HubSpot Blog+1

Advertising platform This is too broad and does not specifically describe software built to manage inventory across multiple ad exchanges through one interface. HubSpot Blog+1
Keyword manager This refers to keyword organization or search campaign work, not programmatic inventory buying across exchanges. HubSpot Blog+1
Targeted advertising manager This is not HubSpot’s defined system term for multi-exchange programmatic ad buying. HubSpot Blog+1
