Finding competitive keywords from query logs to enhance search engine advertising

This study has proposed a topic based competitive keywords suggestion method called TCK to enhance search engine advertising. On the basis of query logs, the method explores the indirect associations between keywords and extracts the hidden topic information to identify competitive keywords. It can help advertisers not only broaden the choices of keywords but also carry out a competitive strategy for search engine advertising. Extensive experiments have been conducted to demonstrate the effectiveness of the proposed method. Results prove that the proposed method performs better than existing keyword suggestion methods, contributing greatly to the keyword suggestion advertising market. (C) 2016 Elsevier B.V.
