  • Patent number: 10390065
    Abstract: An online system receives a video-presentation request from a third party system. The video-presentation request comprises a video and a target audience specification for the video. The online system selects a plurality of users as the target audience of the video based on the target audience specification. From the target audience, the online system generates a sample subset of users and determines a sampled video reach count for the subset of users. A sample user who, as determined by the online system, would have viewed the view for at least a threshold duration, is included in the sampled video view count. The online system estimates a total video reach count for target audience by extrapolating the sampled video reach count for the subset of users to the target audience. The total video reach count can be used to determine a parameter for presenting the video on an online system.

  • Patent number: 10390060
    Abstract: An online system presents a video from a third party system based on a video view value generate by the online system. Based on a target audience specification from the third party system, the online system selects a plurality of online system users as the audience of the video. The online system presents the video the selected users in a duration of time equal to a video presentation period received from the third party system. A play of the video by a selected user constitutes a historical view. The online system generates a video view value for the video based on historical views of the video by the selected users. The online system further applies the generated video view value for pacing delivery of the video by the online system.

  • Patent number: 10325283
    Abstract: An advertiser specifies an advertising campaign along with a budget, a duration and one or more objectives associated with the advertising campaign. An online system presenting advertisements from the advertising campaign determines an interval representing a portion of the duration, an interval budget, and one or more interval objectives. Historical information describing selection and presentation of advertisements by the online system is retrieved, and used to determine one or more filters limiting the number of opportunities to present an advertisement in which advertisements from the advertising campaign are included. The scaling filters may be based on the one or more interval objectives, bid amounts determined for advertisements in the advertising campaign, and bid amounts associated with advertisements previously selected for presentation form the historical data.

  • Publication number: 20190172100
    Abstract: An online system guarantees achievement of an impression goal and a reach goal associated with a set of content items received from a content-providing user of the online system within a period of time associated with the goals. To ensure that the goals are achieved within the period of time, the online system may adjust values of filters associated with the set of content items that control a number of impression opportunities for which the set of content items will be eligible for presentation to users of the online system. The online system may compute a normalized ratio throughout the period of time associated with the goals based on the goals and the progress made by the online system towards achieving the goals. Based on the normalized ratio, the online system may track the performance of the content items and adjust the values of the filters.

  • Publication number: 20180218406
    Abstract: An online system scores campaign audiences based on historical scoring data for similar audiences. A third party system selects a target audience and a day on which the target audience should be exposed to a campaign. The online system generates an availability grid and a score grid to determine a score for the target audience. Values in the availability grid are determined based on the availability of exposure time for the target audience on the specified date. Values in the score grid are based on historical scoring data for the same audience. The online system scores the target audience by interpolating between data points in the score grid based on a selected availability from the availability grid.

  • Publication number: 20180150856
    Abstract: An online system provides a third party system with the trend in the total monetary value over time for groups of users that meet specific targeting criteria provided by a third party system. The target groups of online system users are divided further into segments according to demographics within the group and their respective base values are observed over an observation time period. Trend values for each segment are formulated based on changes in the respective base values over time. These trend values are weighed according to the number of online system users comprising each segment. More users in a segment results in a larger weight placed on the trend value associated with that segment; fewer users results in a smaller weight. The final value associated with the entire target group of users derives from combining the trend values for each segment within the target group.
