Bulk keyword competition tool?

[AdamThompson]

The SEOmoz Keyword Difficulty tool is great, but the 5 keyword limit is too small. I need a tool that will allow checking the organic competition level of 100's of keywords (to help in selecting blog topics). Anyone know of such a tool?

Hi Adam,

I am a big fan of Long Tail Pro for keyword competition research. It allows you to add as many of your own keyword phrases and check the competitiveness, but I find it more useful by putting in 5-10 keyword phrases and then it will use the Google AdWords Keyword Tool to come up with literally thousands of related phrases to analyze by competition and search volume. Click on an individual keyword phrase and you will get a more detailed competitive analysis of the top 10 results in Google. I'm pretty sure there is a free trial but I found it to be one of the most useful SEO tools I have come across in years so it is money well spent.
