Methods, systems and apparatus, including computer program products, provide adjustments to advertisement impression estimates based on sampled data. According to one method, an estimated number of advertisement impressions is made based on the sampled data and the estimate is discounted to achieve a level of certainty that the resulting discounted estimate is less than the actual number of advertisement impressions. The amount of the discount can be determined based on a sampling error model of the sampling data.
