I just had to tell you about a brand new, free keyword research tool that Brad Callen just released.

It allows you to uncover and view the AdWords keywords of ANY AdWords advertiser! Basically, it’s a small file that gets installed into your web browser (i.e. Firefox).

When you do a Google search, the software automatically places a “view keywords” button below every single AdWords advertiser.

Click the “view keywords” button and really neat popup window appears that not only shows you the keywords that any AdWords advertiser is bidding on, but it also shows you a TON of other information, like how much they’re paying per click and so on.

It’s awesome.

Anyway, here is the link where you can download the software, and it doesn’t cost anything.
