Which is right? Why are they so different sometimes? WT = Wordtracker Free tool GAKT = Google Adwords Keyword Tool The traffic measured is daily traffic. "job boards" - WT - 4532 - GAKT - 2,387 "job board" - WT - 40 - GAKT - 4354 "job search" - WT - 8404 - GAKT - 88,387 "job listings" - WT - 3292 - GAKT - 21,709 "job listing" - WT - 87 - GAKT - 7935 In addition there are key phrases listed on the free GAKT that are not on the Free WT tool at all? Does the pay wordtracker have more phrases?
Seems there's a 1/10thish' difference between WT and GAKT. If I was to put my faith in one or the other, i'd have to be GAKT.
They say that Wordtracker uses information not only from Google but from other SE. Anyway both are helpful only to compare keywords not to get exact numbers.
