If your keyword looks bad, do not consider yourself totally loser. Try again (and think differently) and stay free. There are more comfortable words you can go to. For example, getting a rating for a keyword like a "Buy Website Traffic" is harder than, for example, a "Buy Traffic". If you can optimize your site for a few keywords, you will be more likely to attract visitors by gaining rank for a hard word.
