Recently, I had a chance to play with the free version of PPC Web Spy by Brad Callen, and I’ve got to admit it’s one little cool Firefox Plug-in. First I was a bit skeptical about the product. After all, not many free plug-ins live up to the expectations (SEO for Firefox is one of few that does). But I was quite impressed on how easy this tool makes it to spy on others.

Once you download PPC Web Spy, you are going to be asked to restart your Firefox. That’s when great things are going to happen. Once you log back to Google and search for a phrase, you are going to be presented with the following:

The view keywords button allows you to find out the keywords that each advertiser is using to display their ads. Talk about hitting the jackpot.

As you can see in the above image, you get the keywords, the average position, the average CPC, Max CPC, and all that good stuff. You can also see ad per keyword, which should give you an idea about the techniques used by your competitors to achieve a higher CTR.

But that’s not all. You also can expose the destination URL used by these guys (see below).

Now, if you decide to go to with Gold or Platinum editions of PPC Web Spy, you also get a chance to download all the keywords your competitors have, which is pretty convenient. Now, you should be able to see most of the keywords that are used by your competitors, but the domain in question should be at least 45 days old in the Adwords system. This tool is very useful if you want to get a quick report on your competitors or folks advertising in a specific niche.
