In one embodiment, a method determines advertisement (ad) impressions previously determined for a site and respective predicted probabilities determined for the ad impressions. A mapping table is generated mapping predicted probabilities to respective precisions using seed data associated with the ad impressions. The method generates optimal options for using the first level and the second level for the segment using the mapping table. The optimal options include a first precision for the first level, a second precision for the second level, and a ratio of ad inventories allocated to the first level and the second level. Then the method selects one of the optimal options. The selected one of the optimal options includes parameters including a first threshold for the first level, a second threshold for the second level, and the ratio that are used to test whether a predicted probability for an ad impression is targeted to the first level or the second level. |

1. A method for providing a first level of ad targeting and a second level of ad targeting, the method comprising:
determining, by a computing device, advertisement (ad) impressions previously determined for a site and respective predicted probabilities determined for the ad impressions, wherein a predicted probability is a probability that an ad impression belongs to a segment that is being targeted; generating, by the computing device, a mapping table mapping predicted probabilities to respective precisions using seed data associated with the ad impressions, the seed data including features for users associated with the ad impressions; generating, by the computing device, optimal options for using the first level and the second level for the segment using the mapping table, the optimal options including a first precision for the first level that is greater than a second precision for the second level and a ratio of ad inventories allocated to the first level and the second level; and selecting, by the computing device, one of the optimal options, wherein the selected one of the optimal options comprise parameters including a first threshold for the first level, a second threshold for the second level, and the ratio that are used to test whether a predicted probability for an ad impression is targeted to the first level or the second level. |
