Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for estimating performance parameters. A method includes: identifying selection criteria including one or more words, phrases or categories for use in a campaign; identifying a time in the future; estimating one or more performance parameters associated with execution of the campaign at the time in the future including for each performance parameter: identifying a time series based on historical inventory for the performance parameter; identifying and correcting for discontinuities in the time series to produce a corrected time series; evaluating the corrected time series for periodic components; evaluating the corrected time series for trends; extrapolating the corrected time series into the future based on the evaluating for periodic components and trends; and determining, for the time, estimated values for the performance parameter; and providing the estimated values for the one or more performance parameters. |
