OP, is the problem that you do not like the new keyword planner, or that you don't like change?
Me, I just hate someone changing a system I already know.
It will take an hour or so re-learn how to use it. (you Tube)
As for alternatives, I have and use Market Samurai, it is especially useful when looking at the competition you are up against. If you hae trouble figuring out what the data means, MS is a good solution for you. I believe it is available on the forum and has a free trial.
I have and sometimes use long tail pro. I bought the lite version mainly because it is a quick way to use the google adword planner without going thru their interface, and at $17,it was worth it as a convenience. You fire up LTP, and let it do quick and dirty data retrieval, useful for when you just want the raw data or when you want to confirm the numbers from prior research.
I used Stealth Comptition Keyword Analyzer too, and it was my favorite for niche work. but it is not available because of the change. In a few months when it becomes available, I will buy it.
If anyone bought it and do not like it, let me know, I'll swap you for it. (It was available here, and I meant to buy it....)
The folks who own Ultimate Niche Finder are members of this forum, and it is supposed to bea good program. Cannot find a trial, so I haven't tried it.
Also, there is a tool called "Niche Finder". I do not thik it is the same as "Ultimate niche finder", but it may ahave some good points.
All that being said, in IM, you need to b ale to use he major tools to be successful. Google tools are the major tools.
