Abstract
Search queries which are used to assess performance of search listings are filtered such that the remaining search queries more accurately represent behavior of human users genuinely looking for information in a search engine. Search queries which come from unrecognized user agents or which come from the same network address too closely together or too regularly are removed. If a volume of search queries for a given search term in a period of time exceeds an expected volume, search queries for that term are discarded.
