Abstract
The invention relates to a method for preventing search fraud in a content management system. For an update of a content item of a search index of a search service provided by the content management system ranking metrics are calculated using a set of one or more search queries from a collection of search queries previously received by the search service. At least one statistic is computed using the calculated ranking metrics and compared with at least one statistic provided by a statistics history database. Depending on the result of the comparing, the update of the content item is flagged as fraudulent or as non-fraudulent.
