Selling software over the Internet with Google AdWords has a lot of traps that we should learn to avoid as good as possible, so that our ads reach more targeted prospects every day. One of the trickiest aspects we should be in control of is the use of negative keywords, because they are the toughest candidate for wasting our money and for getting on the nerves of Google users, as it was eloquently explained by Linda Bustos on Get Elastic blog.

Negative keywords in your AdWords keyword list are those for which your ads will not show in search queries containing them.  You can get the general information about negative keywords directly from the AdWords blog.

When you’re trying to sell software through PPC campaigns, your goal is to obtain qualified leads to your software selling business, not to get as much and as untargeted traffic as possible. And that’s when negative keywords come in. Or out, actually:).
