Hi guys. I am just giving out review for Traffic Travis which I personally use for keyword research. Now i dont use it for finding the KW search volume..i use it for competition research..here are few screenshots that will help you understand:
Now I mainly use the Seo Analysis part to find info on my competiton..
What the terms mean:
Age and PR you must be knowing.
BL = Backlinks to that page
BLS = backlinks to the whole site
TBL = Backlinks from gov and edu sites
DMOZ & YAHD = whether listed in DMOZ or Yahoo Directory
Title = if the Keyword is present in site title
Desc = if the kw is in site meta description
H1 Tag = if the KW is in h1 tag
GCA = age in days of google's cached version of this page
CEXT = no. of sites linking to the domain from country(tld) of initial search
