Is there any tool out there that gives you an indication of how competitive it is to get high Serps for a particular key word or phrase. i know that google's tool let you know how competitive the advertising is for key phrases...but i was hoping that there was some way to know how how difficult a key word is before starting a link building campaign. (probably only google has such a tool!)
WordTracker assigns KEI which is determined by the number of searches for a particular keyword and the amount of sites competing for that phrase or keyword. The higher the KEI the easier it is to rank well. HTH
