I'm wondering whether there is any chance in ranking first for "2008 stars" when my URL has 2007stars and was so far optimized for "2007 stars" as they keyword phrase? Or would it be more advised to start with a new domain? The domain with 2007stars in it is 5 months old and has a PR5 and ranks well. I would like some advice as to what would be easier to optimize for "2008 stars". I mean, I could always replace all the keywords "2007 stars" with "2008 stars" on the site to help it rank better I guess, but would that seem weird to the SE?
