What is a correct statement about a demand-side platform (DSP)?

A demand-side platform (DSP) is a technology used by advertisers to automate the purchasing of ad inventory across various publishers’ websites and other platforms. The core function of a DSP is to give advertisers the ability to buy ad space efficiently and at scale. By aggregating inventory from multiple sources, a DSP allows advertisers to access a wide network of publishers to reach their target audiences effectively.

The correct statement highlights that a DSP sells inventory on behalf of publishers across the internet, which accurately depicts the role of a DSP in the digital advertising ecosystem. It acts as an intermediary that helps advertisers buy ad space from various publishers, thus facilitating the flow of advertising dollars towards the appropriate digital real estate based on targeting data and campaign goals.

This function makes DSPs essential tools in programmatic advertising, enabling advertisers to optimize their ad spend and achieve better outcomes while also supporting publishers by ensuring their inventory is sold effectively.
