I’ve been asked over and over what’s the best keyword tool and I only have one pick.
Keyword Elite.
Go there and get yourself a thorough education on keyword research because if you pick the wrong keyword for your blog, you’ll never get good rankings in the search engines. This goes for the keywords you use in your post titles as well.
I’d like to go into a long discourse on keyword research but will save that for the pros.
The person to get schooled on about keywords is Brad Callen the creator of Keyword Elite.
Brad is not some fly by night internet marketer trying to sell you crap in a box. He’s been in the keyword business for a long time and I respect his craft. So much, I’ll promote him.
