I got pinged this evening on a new free tool that has been floating around. It’s a plugin for firefox called PPCSpy. Basically, you install it in firefox, and it puts a little icon down in the lower right corner of your page.

Turn the plugin on by clicking on the icon and do a google search for your desired niche. You’ll see a bunch of green boxes pop up under the adwords ads. Click those boxes and you get a sampling of the keywords that that advertiser is using.

With the free version, you only get to see the first 10 keywords, but there are levels of paid use that allow for 50 and 100 keywords. There’s plenty of other features as well that make it well worth picking up for free if you do any PPC work. Or at least at first glance.

I’ll be giving it a bit of a test drive over the next few weeks.
