It also lets publishers sell impressions to a broader audience of clients and make the bidding range usable for maximizing the suppliers’ revenue.

The advertiser uploads advertising materials (link to the landing page, creative) and sets the targeting (GEO, browsers, languages, devices, OS, etc.). Thus, a huge number of different advertising campaigns for different advertising formats and targets are consolidated within one system. Such a platform can also buy traffic directly from webmasters

- The SSPs have a look at the data like demographic, location, etc., through website cookies and determine what ads might be relevant.
- DSPs help advertisers decide which ad slots to bid for, how much to bid, etc.
- SSPs have a look at the bids on the exchange and choose the winner based on their relevance with regards to the bid size, content, and the bid amount.
- The auction is completed, and the ad is displayed on the web page instantly.
- The entire process occurs while the webpage is loading.
