Claim:
A system for selecting ad words for purchase, comprising: an information database; and a processor configured for: processing the information database using orthogonal corpus indexing and a seed topic to derive a plurality of candidate ad words; receiving an estimated upper and an estimated lower cost per click (CPC) value for each of the plurality of candidate ad words; computing estimated upper and estimated lower marketing break even (MBE) values for each candidate ad word of the plurality of candidate ad words based on corresponding estimated upper and lower CPC values, wherein each estimated MBE value of a corresponding candidate ad word represents an estimated cost of an advertisement relating to the corresponding candidate ad word; computing an average MBE value for each of the plurality of candidate ad words based on corresponding estimated upper and estimated lower MBE values; selecting one or more ad words from the plurality of candidate ad words as a function of average MBE values associated with the selected one or more ad words; receiving a measured upper and a measured lower CPC value for the one or more selected ad words based on an advertisement deployed relating to the one or more selected ad words, wherein the measured upper and the measured lower CPC values represent actual costs for one click on an advertisement related to the one or more selected ad words; computing a measured average MBE value for the one or more selected ad words based on the measured upper and measured lower CPC values, wherein the measured MBE values for the one or more selected ad words represent actual cost of the advertisement relating to the one or more selected ad words; and removing an ad word from the one or more selected ad words that has a measured average MBE value higher than a threshold.
