Quick question:

When choosing the most important keyword set that I would like to rank for, would I be better off optimizing my homepage, or a sub page for this keyword.

My thinking goes as follows: The homepage (IE www.mysite.com) naturally has more backlinks and thus a better Google Page Rank.

However, there are certain things I could do to a subpage (IE www.mysite.com/green-widgets-los-angeles ) that I wouldn't want to do to the homepage, which might be more "optimal" overall.

Option C, I suppose, would be to optimize both the homepage, and a single sub-page, which is seeming like a pretty good solution, but I have been told that having multiple pages optimized for the same keywords might "confuse" search engines.

Would love any insight on this!
