For example, types of advertisements are associated with advertisement slots based on values for presenting various types of advertisements in different advertisement slots and one or more ad placement rules. Candidate advertisements having an advertisement type associated with each advertisement slot are identified, and an expected value of various placements of the candidate advertisements having a type corresponding to advertisement slots is determined. Based on the expected values, a placement of candidate advertisements in advertisement slots is selected and presented to a user.

Abstract: For ad campaigns that have multiple advertisements, each associated with an ad creative, which are automatically selected, an online system may bias selection of advertisements away from underestimated advertisements and towards early-selected advertisements with positive user interactions. To increase the likelihood of various advertisements in an ad campaign being evaluated for presentation to users, the online system may: associate a relatively high performance score with each advertisement in an ad campaign, randomly select advertisements from an ad campaign, modify bid amounts associated with advertisements in the ad campaign, or allocate a portion of the ad campaign's budget for allocation across advertisements in the ad campaign. After presenting a threshold number of advertisements in an ad campaign or receiving an instruction from an advertiser, advertisements from the ad campaign may be selected using conventional methods.
