Previously I wrote this similar post for this tool: http://www.goodkeywords.com/products/gkw/ This is one I have used and recommended for many years no ads, no signups, its just a tool put out for free by a company many years now. I am not affilaited with them, and you can see, its not something they (or me for referring) make money for. They have all kinds of advanced softwares and memberships...I HAVE NOT USED ANY OF THEM..so I can't say good or bad, I just know the FREE KEYWORD TOOL is great I still stand by it because of its functionality: 1) Site and link Pop - at a glance for MULTIPLE SITES In a table, one row per site: PageRank, Alexa Rank, Alexa Links, Online Since, Google Links, Yahoo Links, Altavista Links 2) A Keyword PHRASE BUILDER 3) A KEYWORD ORGANIZER - to keep track of all your results 4) MISPELLINGS (which allow you to toggle whether or not you want to take into account duplicate characters, missing characters, swapped characters and oh yes - keyboard proximity errors!) Thats the basics, the tools are all integrated together, and there are a half dozen other useful functions in the software. Check it out yourself, its so good I wish I could SELL IT, but its free for everyone Now PLEASE NOTE: Since overture is dead for research, if ALL YOU WANT IS SEARCH COUNTS Use Googles FREE keyword tool...it is MORE ACCURATE than WORDTRACKERS tool: https://adwords.google.com/select/KeywordToolExternal final note: I use all 3 mentioned here
