What types of margins are there in programmatic?

Buy-Side Margin: This is the margin taken by demand-side platforms (DSPs) or agencies. It represents the difference between what the advertiser bids and the amount paid to the supply side (publishers). Sell-side margin: The difference between what the advertiser pays and what the publisher receives. Ad Tech Fee: Some platforms charge a fee for using their ad tech services. Markup: In some cases, intermediaries might add a markup to the cost of media before selling it to the advertiser.
