A lot of decisions are made between the time someone shows up on a website and when an ad loads on the page. But many of those decisions are left up to advertisers and the demand-side platforms they deploy to do their programmatic ad buying. Fewer decisions are made by publishers and the supply-side platforms they use to sell impressions.
But it doesn’t have to be that way. With programmatic processes speeding up, publishers and SSPs can do more merchandising of impressions before they are put up for auction. This merchandising can take different forms — such as setting price floors, adding contextual signals and affixing brand suitability scores to a bid request — all of which can fall under the umbrella term of sell-side decisioning, as the video below explains.
