Choose a phrase that is popular, but not too popular

When trying to decide on a keyword phrase, you want to find one that is popular but not extremely popular. This may seem counter-intuitive, but the reality is that extremely popular keywords are very desirable and so very competitive. It's better to try to optimize for keywords that you can rank higher. You'll get more pageviews from a less popular keyword when you're on the first or second page of the search engines, than from a super popular keyword that you only make it to page 50 of search engines.
