Increasing Page Rank
Using the right keywords in your title tag will not ensure you a top ranking with Google, but ignoring it or using poor keywords can certainly damage your chances. Choosing solid relevant keywords for your title tag is one of the most basic steps in SEO
Finding your target keywords
You will notice with the Google Keyword Tool that if you type in a keyword (you can use short or long tail) not only will it give you the level of advertiser competition displayed on a bar, and the local and global search results for that keyword, but it will also give you the results for some more targeted keywords that you might be interested in. It occasionally gives you some results out in left field, but for the most part the data is helpful in at least getting the ball rolling.
