DSP stands for Demand-Side Platform. It’s a technology platform used by advertisers and agencies to manage ad campaigns across multiple ad exchanges, websites and other digital media platforms. DSPs give advertisers access to a large pool of digital ad inventory and the ability to target specific audiences with their ads.

Some of the key features of DSPs are:

1. Real-time bidding: DSPs use real-time bidding (RTB) to automate the programmatic buying of ad space in real-time auctions.
2. Ad targeting: DSPs allow advertisers to target specific audiences based on demographics, interests and behaviour.
3. Ad Spending Optimisation: DSPs use algorithms and machine learning to optimise campaigns and improve performance over time.
4. Analytics: DSPs provide advertisers with detailed analytics and reporting on ad performance, impressions, clicks, conversions and more.

In summary, DSPs help advertisers reach their audience better, maximise their ad spend and get better results from their programmatic campaigns.
