Also, when checking for competitors - always use your keyword phrase in quotes. If you are a noob, try to find competition under 100,000 results. Ideally 60,000 or lower.
*Cool tip* Keep clicking on the last page of google results until you come to the last page of results You will find that the 60,000 might reduce down to 2000 or so. It works for me, because it lets me know what keywords I can kill with. Then I work on optimizing those keywords.
