Google Trends allows a user to compare among two to five keywords with respect to how many times users have searched, and how many times such have appeared on news items, as keywords and topics. check for the link at New tool section of http://submitedge.com/seo_tools.html Regards
this is a nice tool till you realize the searches on your main term are declining and have been for almost a year now...
Just curious. How do you guys make use of the results? I mean, so what if searches for some keywords are on the rise? Do you start writing about them then?
