I use the Adwords Keyword Tool to find Keywords. I only check Exact or Phrase and then I find how many searches the KW gets. I used to use the Competition Bar to find out how competitive a Keyword is. But I think this is actually worthless. Because it is made for Adwords. If it says a Keyword has low Competition it just means not many People are buying this Keyword from Adwords, but it could still be very competitive. Am I right?
