8. A system comprising: at least one processor; a memory coupled to the at least one processor; and a processor-implemented keyword selection module configured to: receive a plurality of keywords to be trafficked on a search engine; automatically select at least one of the plurality of keywords to be omitted from trafficking on the search engine based on pruning criteria, the automatically selecting comprising: for each one of the selected at least one of the plurality of keywords, determining a corresponding confidence level with which a corresponding predicted value of the at least one of the plurality of keywords is expected to satisfy the pruning criteria; and for each one of the selected at least one of the plurality of keywords, determining that the corresponding confidence level satisfies a configurable confidence level threshold, the automatic selection of each one of the selected at least one of the plurality of keywords being based on the determination that the corresponding confidence level satisfies the configurable confidence level threshold; generate a report, the report comprising the selected at least one of the plurality of keywords and a corresponding value for each one of the selected at least one of the plurality of keywords, the corresponding value being based on the corresponding one of the selected at least one of the plurality of keywords being omitted from trafficking on the search engine; cause the report to be displayed to a user; and remove at least a portion of the selected at least one of the plurality of keywords from being trafficked on the search engine based on the selection of the at least one of the plurality of keywords to be omitted, the removing of the at least a portion of the selected at least one of the plurality of keywords being performed in response to a user input corresponding to the report, the user input being used to determine the at least a portion of the selected at least one of the plurality of keywords to be omitted.

The system of claim 8 , wherein the corresponding value comprises a corresponding loss of revenue.
